Pinenut oil pinolenic acid microcapsule and preparation method thereof

Abstract

The invention belongs to the field of food processing and discloses a pinenut oil pinolenic acid microcapsule and a preparation method of the microcapsule. The pinenut oil pinolenic acid microcapsule has a weight reduction function and can reduce cholesterol (TC) and triglyceride (TG) and increase high density lipoprotein (HDL). The preparation method comprises the following preparation steps of: extracting pinolenic acid, preparing a core material solution, preparing a wall material solution, and encapsulating a microcapsule. By adopting the preparation method disclosed by the invention, the extraction rate of the pinolenic acid from pinenut oil is more than 70%, the pinenut oil pinolenic acid which is easily oxidized is microencapsulated to effectively prolong the quality guarantee period, and the encapsulation rate is more than 85%.

Description

Technical field:

[0001] The invention belongs to the technical field of intensive processing of agricultural by-products and comprehensive utilization of by-products, and relates to a preparation method of pinolenic acid microcapsules in pine nut oil, which can achieve an embedding rate of more than 85%. Background technique:

[0002] Pinolenic acid is an unsaturated fatty acid in pine nuts first announced by Norwegian scientists in 1997. It is different from unsaturated fatty acids in all plants on the earth. It only exists in pine nut oil and can not only lower cholesterol (TC) , triglyceride (TG), increase high-density lipoprotein (HDL), and can also inhibit and eliminate the adverse effects of other unsaturated fatty acids on the body. It is a functional weight loss health food with development prospects. Pinot Leptinic acid can significantly reduce the body weight of nutritionally obese mice, but its stability is poor, and it is very prone to denaturation reactions unde...
