摘　　要：采用吡啶甲酸铬、乳酸锌和可溶性膳食纤维等作为功能成分制备辅助调节血糖的保健奶粉。生产过程采用微胶囊技术,将膳食纤维、吡啶甲酸铬和乳酸锌作为功能成分,酪蛋白、糊精和膳食纤维为壁材,植物油(富含油酸、亚油酸)为芯材,经喷雾干燥得到降糖奶粉基料,与脱脂奶粉干法混和得到一种功能保健食品——高纤、有机铬、锌、降糖奶粉。实验摸索了降糖奶粉中试生产的工艺条件,讨论了影响乳酸锌乳化液稳定性的因素,并利用火焰原子吸收法对产品中铬、锌的分布情况进行了分析。Diet fiber, chromium picolinate and zinc lactic are the effective components for lowing blood glucose level in human body. Vegetable oils (corn and soybean oils) rich in oleic acid and linoleic had been encapsulated by casein, dextrin and soluble diet fiber, the emulsion was dried in pilot scale sprayer. The optimum processing parameters by pilot scale production were determined. Factors of zinc lactic influencing emulsion stability were investigated and distribution of chromium and zinc in end product was analyzed by FAAS.
