摘要
以淮山药粉为原料,以复合指数(composite index,CI值)为指标,制备淮山药粉-硬脂酸复合物(Chinese yam powder-stearic acid complex,CYP-SAC)并研究其理化特性。结果表明,淮山药粉-硬脂酸复合物的最佳制备工艺为:硬脂酸添加量为淮山药粉质量的4%、复合温度为55℃、复合时间为2 h,所得CYP-SAC的复合指数为(86.81±1.40)%,其平均消化率(5.62±0.4)%、透明度为(28.1±0.8)%、凝沉稳定性为55%~65%。
Taking the Chinese yam powder as raw material,the preparation technology and physicochemical properties of Chinese yam powder-stearic acid complex(CYP-SAC)were studied with the index of composite index(CI). The result showed that the optimum preparation process of CYP-SAC was that the addition of stearic acid was 4 % of the content of Chinese yam powder,the composite temperature was 55 ℃,and the composite time was 2 h. The composite index of CYP-SAC was(86.81±1.40)%,the average digestibility was(5.62±0.4)%,the transparency was(28.1±0.8)%,and settlement stability was 55 %-65 %.
