几种蛋白壁材制备紫苏油微胶囊

Different Protein Preparation of Perilla Oil Microencapsule Wall Material Research

以紫苏油为芯材,固定芯壁比1︰1,利用乳化和喷雾干燥制备紫苏油微胶囊。以包埋率为主要考察指标,考察酪蛋白酸钠、乳清分离蛋白、大豆分离蛋白分别与麦芽糊精复配,以及酪蛋白酸钠与麦芽糊精不同比例复配,酪蛋白酸钠与不同壁材填充剂(麦芽糊精、玉米糖浆、乳糖)复配。结果表明,酪蛋白酸钠与麦芽糊精复配包埋率远高于其他蛋白与麦芽糊精复配,酪蛋白酸钠与麦芽糊精以质量比1︰1复配时包埋率达最高,玉米糖浆作为壁材填充剂有助于提高包埋率。

With perilla oil as core material and fixed core wall ratio of 1︰1, the microcapsules of perilla oil were prepared by emulsification and spray drying. The embedding rate was used as the main index to investigate the combination of sodium caseinate, whey protein isolate and soybean protein with maltodextrin, sodium caseinate with maltodextrin in different proportions, sodium caseinate with different wall material filler. The results showed that the embedding rate of sodium caseinate and maltodextrin was much higher than that of other proteins and maltodextrin, and the embedding rate was the highest when the sodium caseinate was mixed with maltodextrin 1︰1.
