摘　　要：综述了用于评价稻米加工品质的拉应力、弯曲应力、剪切应力的测定方法和主要设备,阐述了稻米力学特性与其品质的关联性。并分析了稻米的胚乳结构、厚度、裂纹、垩白、水分、直链淀粉含量、蛋白质含量等因素对稻米力学特性的影响。研究结果表明,稻米的力学特性是决定其加工品质的一个重要因素。目前对稻米力学特性的研究尚未成熟,还需进一步深入研究。Methods and main equipments to determine the tensile stress, bending stress and shear stress for evaluating rice processing quality were summarized. Endosperm structure, thickness, crack, chalkiness, moisture content, amylase content, protein content and other factors of rice on its mechanical properties were analyzed. Seen from the research results, rice mechanical property was an important factor to determine its processing quality. At present, researches on rice mechanical properties haven＇t become mature yet, thus further research work is still required.
