Abstract:Rice was packed by different barrier material with vacuum packing.The relationship between rice quality and time in high temperature and high humidity conditions was studied with moisture content, fatty acid value, amylose content, chewiness, adhesion as evaluation indexes.The results indicated that the high-barrier material such as PA/EVOH/PE could reduce the effect of bad environment on the moisture content of rice, delay the change of fatty acid value and amylose content, reduce the rate of the decrease of the adhesion, and keep the rice chewiness in relatively stable. As result, high-barrier material could effectively delay the quality deterioration of rice and extend the rice storage period in high temperature and high humidity conditions.
