大蒜油树脂微胶囊生产工艺的研究

Studies on microencapsulation process of garlic Oleoresin

本文报导以鲜大蒜为原料，用５５％酒精为溶剂，经连续渗漉所得油树脂为心材，以食用胶为壁材，经乳化、均质、喷雾干燥而得制备大蒜油树脂微胶囊的工艺程序，并进行了技术参数的检测：微胶囊含水率７．１２％、心材包埋率９７％、收得率８９．５％、有效成分含量０．４７５８％（Ｗ／Ｗ）、溶剂残留量４．２ｐｐｍ。

Microencapsulation process of garlic oleoresin which was extracted as core-material from fresh garlic with a 55% ethanol solution was .investigated,including emulsion and spray-drying,The edible gums were selected as wall-material.The moisture content in microencapsulation of garlic oleoresin microencapsulation and retention ratio of core-material are 7.12%, 89.5% and 97% respectively.The content of garlic active principle in microencapsulation is 0.4758%.(w/w) remnant of solvent is .2ppm.
