Abstract:Indonesia’s agroindustry is an economic pillar but is hampered by high food loss and waste (FLW) caused by inefficient logistics, inadequate cold chain infrastructure, and fragmented supply chains. FLW leads to economic losses of 4%~5% of Indonesian GDP, further leading to food insecurity and environmental degradation. This paper proposes a Smart Agroindustry Framework that integrates the Internet of Things (IoT), Artificial Intelligence (AI), Blockchain, and Cloud Computing to optimize food supply chain performance and reduce FLW. Compared to conventional methods, this approach offers real-time monitoring, forecast-based analysis, and traceability to support stakeholder decisions and counter inefficiencies in the supply chain. The three-stage recommended road map comprises: (1) short-term: pilot implementations targeting high-risk perishable commodities, (2) medium-term: expansion into inter-island and multi-modal logistics, and (3) long-term: Nationwide implementation of a Food Logistics 4.0 ecosystem. Through these digital technology approaches, Indonesia has the potential to transition towards a proactive, data-enabled agroindustry that minimises losses and environmental footprints. Beyond Indonesia, this model is adaptable for other developing nations facing similar food security challenges, reinforcing the global movement towards more efficient and sustainable food systems.

Abstract:The digitalization of the grain industry chain plays a significant role in ensuring food security, improving industrial efficiency, and advancing the high-quality development of the grain industry. Survey results from government departments, circulation enterprises, research institutions, and testing organizations indicate that digitalization technologies have been widely applied across various links of the grain industry chain, though the depth of application varies significantly among different links. Digitalization technology equipment primarily consists of domestic brands, with relatively high equipment values. Digitalization technologies can effectively promote grain quality safety and improvement, and demonstrate notable management effectiveness in enhancing management levels, economic benefits, and social benefits. Currently, the digitalization of the grain industry chain faces issues such as insufficient supply in terms of policies, technologies, and investments. It is recommended to provide active policy support in areas such as digital infrastructure construction, financial taxation, pilot demonstrations, and talent cultivation.

Abstract:Grains, as the cornerstone of the global food supply, require quality inspection that is crucial for ensuring food safety and improving production efficiency. Traditional laboratory methods, while accurate, are time-consuming and costly, making them unsuitable for online, real-time monitoring. Near-infrared (NIR) spectroscopy, with its advantages of rapid, non-destructive, and multi-component simultaneous detection, has been widely applied in grain quality inspection. However, the high dimensionality, complexity of NIR spectral data, and variations among different instruments, environments, and samples pose challenges to modeling methods and model transfer. This review summarizes the application of NIR spectroscopy in online grain quality inspection, systematically outlining the development from traditional linear modeling (e.g., partial least squares regression), nonlinear modeling (e.g., support vector machines, artificial neural networks) to deep learning methods (e.g., convolutional neural networks). It focuses on the strategies, challenges, and latest advances of model transfer techniques in addressing issues such as instrument differences, environmental changes, and sample diversity, including calibration transfer with and without standards. Furthermore, this review summarizes the challenges, experiences, and future research directions in practical industrial applications, aiming to provide references for the widespread application of NIR technology in the grain industry.

Abstract:The study explored the effects of different degrees of milling, including the moderate processing technology on the quality of japonica rice using Longdao 18, Longjing 31, Yanfeng 47, Yujingxiang, and Nanjing 46 rice varieties. The results indicated that as the milling intensity increased, the whiteness of the japonica rice and broken rice rate continuously increased, but the bran retention rate decreased. The taste value first increased and then plateaued, while the content of vitamin B1 and mineral elements generally showed a declining trend. From brown rice to the first stage of milling, there was a significant decrease in protein content. During the milling process, the vitamin B1 content in japonica rice was significantly positively correlated with the levels of magnesium, phosphorus, potassium, calcium, manganese, iron, copper, and zinc. Iron was more concentrated in the outer layers, and reducing the milling degree could significantly increase the retention rate of iron. Analysis of the coaxial curve diagram based on the proportion of the maximum value in each group relative to the brown-to-white rice yield for broken rice rate, taste value, vitamin B1, and iron content of five japonica rice varieties revealed that the moderate processing range for japonica rice corresponds to a brown-to-white rice yield of 88% to 92%. Within this range, the taste value of japonica rice reached its highest level, and more vitamin B1 and mineral elements such as iron were retained.

Abstract:To analyze the effects of five kinds of coarse cereals, namely quinoa, highland barley, black rice, triticale and oat, on the glycemic index (GI) and quality of steamed bread. The 5 kinds of coarse cereals were incorporated to steamed bread at proportions of 10%, 20%, 30%, 40% and 50%. The GI values of the steamed bread were measured through a GI20 automatic in vitro simulated digestion system. The effects of the coarse cereals on the sensory score, color, texture and other quality related indicators of steamed bread were analyzed. Compared with ordinary steamed bread made from regular wheat flour, with increasing proportions of coarse cereals, the GI value of steamed bread gradually decreased. The sensory quality declined, with lower sensory scores, the internal structure gradually became rough, the hardness increased and the brightness decreased. Under the condition that the sensory score was greater than 75 points, the maximum permissible addition proportions for quinoa, highland barley, black rice, triticale and oat were 10%, 40%, 30%, 60% and 30%, respectively, and the corresponding GI values were 79.94, 67.49, 72.45, 69.61 and 74.52, respectively. The coarse cereal steamed bread made with 40% highland barley flour substitution had the lowest GI value, the best hypoglycemic potential, the highest dietary fiber content, and good sensory quality. This study provides a reference for the development of coarse cereal steamed bread with blood glycemic regulation ability.

The results showed that the optimal extraction conditions for buckwheat polysaccharides were as follows: sieving mesh size of 830 μm, solid-liquid ratio of 1∶35 (w/v), 200 W ultrasonic treatment for 30 minutes, and constant temperature extraction at 85 ℃ for 2 h. The polysaccharide yield was 10.03%. After sequentially separating and purifying DEAE-52 and sephadex G-100, the FTP1 and FTP3 were obtained. Both exhibited characteristic FT-IR absorption peaks of polysaccharides and showed abundant cross-linked networks and porous structures under SEM observations. polysaccharides were composed of glucose, glucuronic acid, mannose, and galactose. They belonged to the β-type and have a triple helix conformation in the aqueous phase. The Mass average molar mass of FTP 1 and FTP 3 were 442 791 g/mol and 25 587 g/mol, respectively. Rheological studies indicated that the tartary buckwheat polysaccharide solutions exhibited shear-thinning behavior, characteristic of non-Newtonian fluids. At a mass concentration of 3.0 mg/mL, FTP1-1 and FTP3-1 showed scavenging rates of 69.16%, 40.66%, 51.98% and 70.33%, 41.48%, 48.52% for DPPH free radicals, hydroxyl free radicals, and superoxide anions, respectively. The ferrous ion chelating rates of the two components were 80.79% and 60.54%, respectively. In conclusion, the two polysaccharides extracted from Jin Buckwheat No. 2 possessed high antioxidant activity. This research could contribute to the processing and utilization of tartary buckwheat polysaccharides.

Abstract:The processing stage plays a key role in connecting upstream and downstream in the industrial chain, and reducing food processing losses is crucial for ensuring food security. Based on field survey data from Anhui and Hubei provinces, this study provides an in-depth analysis of the current processing losses and the potential for loss reduction. The study indicates that rice processing enterprises are oriented to consumer demand, leading to excessive processing behaviors such as multiple whitening and polishing stages. However, improvements in processing equipment and streamlining of processing steps could increase the yield. To address the practical challenges faced in rice processing, it is essential to reduce processing losses by guiding consumer attitudes, promoting moderate processing practices, and upgrading processing equipment. Additionally, efforts should focus on developing deep processing techniques and enhancing the comprehensive utilization of by-products, in order to fully tap into the potential for loss reduction in rice processing and strengthen the foundation of national food security.

Abstract:Superheated steam, as an emerging thermal treatment technology, has garnered significant attention in the field of grain processing due to its high thermal penetration in an oxygen-free environment. This article has reviewed the research progress on the effects of superheated steam treatment on the properties of grain components, edible quality, and storage characteristics. Superheated steam treatment can promote the breaking of disulfide bonds in proteins, altering their conformation, increasing disorder, and enhancing random coil structures. Moreover, the gluten protein network structure can be changed more loose by this treatment, thereby affecting the elasticity and extensibility of the dough. The crystalline structure within starch was also destroyed by superheated steam treatment, promoting the dissolution and swelling of starch molecular chains, causing partial gelatinization of starch, and thus affecting the swelling power and peak viscosity of starch granules. During the treatment process, the presence of an oxygen-free environment helped slow down oxidation reactions and reduce the loss of bioactive substances. The cooking time of grains can be shortened and the production of unpleasant odors can be effectively reduced by superheated steam treatment with high temperature and high permeability. This review also explored the application research of superheated steam technology in inactivating enzyme and grain-related oxidases, and improving the sterilization ability and storage quality of grains. This may provide references for further exploration of the application of superheated steam technology in the field of grain processing in the future.

At last, some suggestions are presented and discussed from the aspects such as strengthening policy support and guidance, promoting R&D and technological innovation and expanding market awareness and acceptance, so as to provide some research foundation and case references to help revitalize China’s soybean industry and promote the further development of plant-based meat industry.

Abstract:Plant phenolic acids are widely distributed in the plant kingdom, mainly divided into two categories: hydroxybenzoic acid and hydroxycinnamic acid, with good biological activity. Starch, composed of amylose and amylopectin, has unique structural and functional properties. After the interaction between plant phenolic acids and starch, the excellent properties of plant phenolic acids are not only transferred to starch, but also modified to further enhance the edible value of starch. This paper has described the interaction mechanism between plant phenolic acids and starch, including non-covalent and covalent binding promoted by physical, chemical and enzymatic methods, and the regulation of their interactions by physical, chemical and biological techniques, and these interactions affect the key properties of starch, such as gelatinization, retrogradation, digestion, swelling, and rheology. These findings not only laid a theoretical foundation for the development of functional foods, but also pointed out the direction for further research on the health benefits and molecular mechanism of plant phenolic acids.

Abstract:Pea protein has broad market prospects due to its low cost, low fat content, absence of animal cholesterol and low allergenicity. However, its poor solubility limits its application. This paper employs the pH-shifting method to modify pea protein and explores the impact of the optimized modified pea protein on the functional properties of various starches. When the pH-shifted modified pea protein was incorporated into different starch systems, it was observed that the peak viscosity and breakdown value of potato starch decreased, whereas those of corn starch and pea starch, as well as their final viscosity and setback value, increased. Thermal analysis (DSC) revealed that the 7-day retrogradation rates of potato starch, corn starch, and pea starch decreased from 31.61%, 49.94%, and 31.85% to 10.75%, 21.70%, and 18.78%, respectively, indicating that the modified protein effectively inhibits the long-term retrogradation of starches. Resistance starch (RS) assays showed that the RS content of potato, corn, and pea starches increased significantly from 4.2%, 4.8%, and 6.3% to 21.4%, 20.7%, and 17.8%, respectively. These results demonstrate that pH-shifted modified pea protein holds significant potential in improving starch properties and enhancing starch resistance to digestion, particularly promising for broad applications in the food and functional materials industries.

Abstract:Upon analyzing literature and patent data sourced from the China National Knowledge Infrastructure (CNKI) and IncoPat, this study delves into the research hotspots and development trends in Gastrodia elata food. The results reveal that the number of Chinese publications on Gastrodia elata food has shown fluctuating growth over the past two decades, with a significant acceleration noted in the last three years. The collaboration network in the Gastrodia elata food research community has become polarized. Major research areas include the identification of active ingredients, the investigation of pharmacological impacts, and process optimization. China leads in terms of patents related to Gastrodia elata food, with Guizhou Province at the forefront. While China is innovatively developing various forms of Gastrodia elata food, South Korea focuses on the compositions of Gastrodia elata food. Health supplements derived from Gastrodia elata are primarily available in granule and tablet forms, with those aimed at enhancing immune enhancement being the most widely prevalent. Looking ahead, strengthening industry-academia-research collaboration and fostering international partnerships is crucial to accelerate the translation of Gastrodia elata food research into practical applications. Additionally, there is a need for a deeper exploration of its diverse potential health benefits.

Abstract:To address the challenges of peeling Cyperus esculentus, a spiral kneading peeling machine was designed using Solidworks, and the material motion within the peeling drum was simulated using EDEM discrete element software. The results show that there is a positive correlation between the angle of the peeling drum relative to the horizontal plane and the the average particle velocity. A larger angle results in more pronounced changes in particle velocity. The offset distance between kneading rollers has a certain influence on the average particle velocity. When the dislocation distance between kneading rollers group is less than 45mm, an increase in the distance leads to a greater amplitude of velocity variation. The curvature radius of the circular section of the kneading claw has insignificant impact on the average velocity of the particles; however, during the kneading process, a larger curvature radius increases the duration of particle interaction. The research shows that when the angle between the drum and the horizontal plane is 5°, the offset distance between roller groups is 45 mm, and the curvature radius of the circular section of the kneading claw is 100 mm, the average particle velocity and particle distribution in the cylinder of the peeling machine are optimized. The research findings not only provide a theoretical basis for optimizing the design and process conditions of spiral kneading peeling machines, but also have practical value for improving the peeling efficiency and oil extraction quality of Cyperus esculentus. Moreover, the research method also serves as a reference for the research on the peeling/shelling mechanisms oother crops similar to Cyperus esculentus.

Abstract:The high-quality grain project serves as the most direct and effective approach to promote the high-quality development of grain industry.

Abstract:The establishment of a sound quality classification standard system in consumer goods, such as food, is conducive to promoting the upgrading of product standards. Although the grade establishment has been incorporated within certain product standards in both national and industrial food standards in a variety of segments, no systematic study on grade establishment has yet been conducted. The present study is an analysis of the establishment of medium grades for 222 products involved in 64 national and 105 industry standards, including liquor, tea, grains and oils, brewing, edible fungi, aquatic products, spices, salt, sugar and general rules of quality.  The number of levels set in 222 products ranged from 2 to 7, with the most established grades being 2 and 3. There are many types of grade names in each standard, and it is most common to use all numbers as grade names. The majority of grade indexes established in the products encompass organoleptic qualities, with numerous products being graded exclusively on the basis of organoleptic attributes. At the same time, certain standards eschew the use of organoleptic quality, employing solely physical and chemical indicators. Conversely, the preponderance of products utilises both types of indicators.. The establishment of these grades has effectively guided and promoted the high-quality development of food products. Nevertheless, challenges persist, including the suboptimal applicability of name establishment and the inadequate characterisation of indicators. This study aims to propose a set of guidelines for the naming of product grades in China's food standards, with a view to enhancing the establishment of such grades. The study also puts forward recommendations for the greater utilisation of indicators such as characterised nutrition and the amount of major raw and auxiliary ingredients input.

Abstract:In this study, the concept of storage temperature and humidity was clarified, and the storage temperature and humidity equations were defined by analogy with the storage temperature and humidity equations, according to which the relationship between storage temperature and humidity and their fatty acid values during the storage period of rice grains was investigated. The paddy with an initial moisture content of 14% was the research object. Under different storage periods, the base storage temperature and storage humidity under different storage temperatures and humidity conditions had been investigated, and the cumulative storage temperature, cumulative storage humidity, and cumulative storage temperature and humidity, as well as their correlations with fatty acid values were calculated. The model between cumulative storage temperature and humidity and fatty acid value was established and validated.The results showed that in the paper, the base storage temperature for fatty acid value of paddy was 15 ℃ and the base storage humidity was 55%. Cumulative storage temperature, cumulative storage humidity and cumulative storage temperature & humidity were significantly correlated with fatty acid values and positively correlated. The model equation was: Y=48.9×exp(−((x−7.566)/8.637)^2) (R2=0.844 1; RMSE=2.063) where: x is cumulative storage temperature and humidity (℃×%×d); Y is fatty acid value (mg KOH/100 g). The model was validated R2=0.867 8, RMSE=2.152, the model is more accurate and can provide a new research method for the analysis and prediction of fatty acid values in rice storage practice.

Abstract:Low-altitude economy refers to an economic form that leverages low-altitude flight technology to promote the development of related industries; It has an importance in the national development strategy. The food industry, as a core part of public life, is particularly closely integrated with the low-altitude economy. The drone industry is at the heart of the low-altitude economy, and this paper systematically analyses a range of drones applications in the food industry within the low-altitude economy, in particular the practical applications and challenges in the areas of drone monitoring of the growth of agricultural products, conducting related agricultural activities, delivering food supplies (including takeaways, perishable food, etc.), and aerial photography. Although the application of low-altitude economy in the food sector has shown initial promise, it faces a series of problems such as limited consumer acceptance, underdeveloped industrial depth, and inadequate legal and regulatory frameworks, etc. There is an urgent need for the government to introduce more supportive policies to facilitate the further development and application of low-altitude economy technologies in the food sector. Additionally, sustained technological innovation is the key to ensuring long-term progress in this field, alongside public convenience. In addition, this paper also discusses how scientific and technological innovation, along with policy guidance can solve the possible problems in the current development of low altitude economy, promote the deep integration of low altitude economy with the food industry,and drive the prosperity of related sectors.

Abstract:Based on panel data from 30 Chinese provinces (excluding Xizang, Hong Kong, Macao and Taiwan) from 2013 to 2021, and building on the theoretical analysis, this paper empirically tests the impact of digital economy on the high-quality development of food industry and its transmission mechanisms. The results show that the digital economy can significantly promote the high-quality development of the food industry, with a greater impact on the eastern region. The mechanism analysis reveals that the digital economy fosters regional innovation capacity, thereby driving high-quality development in the food industry.. Furthermore, the high-quality development of food industry exhibits significant spatial agglomeration and spatial dependence, with high-quality talents playing an key role in transmitting the spatial spillover effects of this development of food industry. Therefore, it is important to leverage talent, stimulate the innovation- driven growth of the development of the digital economy, promote the deep integration of the new generation of information technology with agricultural land, food processing and circulation, and facilitate the integration of urban and rural areas as well as internal and external regional connections within the region, to achieve a high-quality development of food industry.

Abstract:Research on precision and moderate processing of rice and wheat is an effective approach to grain saving and loss reduction, ensure food supply security, safeguard "China's rice bowl" and promote "Healthy China 2030". At present, the precision and moderate processing technology of rice and wheat still faces challenges in balancing taste, nutrition and safety. The development of industrialization is restricted by the conflict between the moderate processing accuracy and market demand, the contradiction between the shelf life of moderately processed products and the purchasing experience of consumers, and the conflict between the balance relationship of the product yield and the cost of enterprise input equipment. Therefore, it is recommended to strengthen the research and development of relevant core technologies and equipment, in-depth science popularization and consumption advocacy, improve the financial compensation policy. Through these multi-end joint efforts, it is possible to improve quality, reduce cost and increase efficiency, enhance consumption drive and enterprise enthusiasm, significantly improve the utilization efficiency of grain resources in the three aspects of quantity, quality and health, facilitate grain saving and loss reduction, and promote industrial upgrading.

Abstract:China is the world's largest producer and consumer of non-Genetically Modified Organism soybeans, and domestic soybeans are mainly used in the field of food processing, which is an important link in the soybean industry chain. Giving full play to the advantages of soybean food processing is the key to promoting the sustainable development of the domestic soybean industry, and it is also an important way to solve the oversupply of domestic soybeans under the background of expanding and increasing production. The study found that China's soybean food processing industry still has some shortcomings, such as insufficient supply of special soybean raw materials, the mismatch between processing demand and production supply, low level of initial processing and low added value, single structure of the deep processing, low level of market demand development, insufficient support for industrial development as well as high international market competition pressure. Therefore, it is suggested that we should adhere to the supply-side structural reform and demand-side management, give play to the leading role of new quality productivity, and take multiple measures from promoting the construction of the whole industrial chain, enhancing innovation guidance, and strengthening policy support, so as to stimulate the power of the processing end and promote the high-quality development of China's soybean food processing industry.

Abstract:An empirical analysis based on China's 2021 Land Economic Survey data, examining the impact of internet use on planting structure adjustments, revealed the following: First, internet use can significantly reduce the proportion of grain cultivation by farmers, leading to a “de-grainization” of the planting structure. This conclusion remained valid after addressing endogeneity issues using instrumental variables in a two-stage least squares estimation. The results remained robust after conducting sensitivity tests using alternative independent variables. Second, heterogeneity analysis by grouping household heads by gender showed that the impact of internet use on planting structure varied under different household head gender conditions. Third, internet use can reduce the proportion of grain cultivation and cause a “de-grainization” adjustment in the planting structure by improving farmers’ access to financial credit availability and reducing the costs of economic crops. According to the research results, it is necessary to firmly hold the bottom line of ensuring food security, pay attention to agricultural production activities of different types of households, and establish multiple paths to promote the “grain-oriented” planting structure.
