以大米粉为原料,研究压热法、湿热法、韧化法处理对大米粉及其抗性淀粉成分微观结构、结晶学和热力学性质的影响。研究结果表明,压热处理后,大米粉及其抗性淀粉晶型由A型转化为特殊B型,抗性淀粉在20 = 12.9。、19.8。出现2个特征峰象征脂质淀粉复合物的形成;湿热处理后,大米粉形成有一定淀粉酶抗性的外壳结构,晶型转向A型,升温在115 ℃附近出现巨大的特征吸热峰;韧化处理后形成了粒度较大但内部疏松的淀粉团粒。表明压热处理后,大米粉及其抗性淀粉形成特殊晶体结构,晶体和热稳定性均提高;湿热处理对大米粉结晶学和热力学性质有一定影响,但对抗性淀粉影响不大;韧化处理对大米粉及抗性淀粉结晶和热...

In this paper, rice was used as a raw material. The effects of hydrothermal treatments on the particle morphology, crystal and thermal properties of rice powder and rice resistant starch were investigated. Results showed that autoclaving caused transition of crystallization from A-to a special B-type aggregates with X-ray pattern peaks at 2θ=12.9° and 19.8° that were attributed to the formation of amylose-lipid complexes. Heat-moisture treatment (HMT) resulted in the formation of enzyme resistant shell structures, and caused reversal to A-ty...
