| 摘 要： | 以绿豆淀粉为原料,采用湿热处理制备颗粒态抗性淀粉,并研究其颗粒形貌、直链淀粉含量、溶胀度、黏度及结晶性质等。试验表明:淀粉经过湿热处理后,抗性淀粉含量显著提高;湿热处理淀粉仍保持完整的颗粒外观,属于颗粒态抗性淀粉,部分淀粉颗粒表面出现了裂纹和凹坑,偏光十字强度有所减弱;湿热处理淀粉的直链淀粉含量明显增加,而溶解度、膨胀度和峰值黏度下降,淀粉糊化变得困难;X-射线衍射图谱表明原淀粉和湿热处理淀粉都为"A"型结晶,且湿热处理淀粉在15.2°、17.4°、22.9°左右的衍射峰强度有所加强。

| Abstract: | Granular mung bean resistant starches(RS)were prepared by heat-moisture treatment(HMT)and the properties of granule morphology,amylase content,and solubility,swelling power,viscosity and crystalline structure were investigated.Compared to native starch,the RS contents of HMT starches were increased significantly.After heat-moisture treatment,the integrity of starch granules was retained and HMT starches belonged to the type of granular resistant starch.Concavity as well as crack could be observed on HMT sta... |
