新疆核桃粉的微胶囊化研究

The Research on Microcapsules of Walnut Powder in Xinjiang

以核桃粉微胶囊为试材,研究其抗氧化稳定性。通过对微胶囊壁材乳化剂的溶解性和不同溶剂对微胶囊粉中油脂溶解度的试验,确定正己烷对壁材溶解性最佳。通过进行核桃粉微胶囊氧化稳定性的试验,确定其包埋率80.2%,微胶囊的货架期233 d,采用索氏抽提法得到微胶囊油脂含量30.4%。研究表明,经微胶囊化后核桃粉中油脂氧化稳定性明显提高。

Based on walnut powder microcapsule material, this paper studies its oxidation stability. By means of the microcapsule wall material solubility and fat solubility in different solvents on the micro capsule powder of the test, determine the n-hexane for the solubility of the smallest reagent for wall. Through walnut powder microcapsule oxidation stability test, determine the embedding rate is 80.2%, the microcapsules of shelf life for 233 days, soxhlet extraction and microcapsule oil content is 30.4%. After the study shows that the microcapsule of walnut oil oxidation stability improves obviously in the powder.
