Abstract

The invention provides microcapsule powder containing linseed oil and walnut oil. The microcapsule powder is prepared from, by weight, 1-1000 parts of wall material, 5000-50000 parts of core material, 10-1000 parts of emulsifier and 1-200 parts of stabilizer, the wall material comprises one or multiple of dextrin, starch and protein, and the core material comprises the linseed oil and the walnut oil according to a weight ratio of 1-2:1. The invention further provides a preparation method of the microcapsule powder. The preparation method includes: sequentially preparing a water phase and an oil phase; emulsifying, homogenizing, and spraying and drying to obtain the microcapsule powder. The microcapsule powder has the advantages that the linseed oil and the walnut oil are mixed and emulsified according to a certain proportion to prepare oil-in-water microcapsule powder, and the microcapsule powder is easy to store, long in shelf life, balanced in nutrition, needless of antioxidant adding and highly good for human health.

Description

technical field [0001] The invention relates to the field of microcapsules, in particular to a microcapsule powder containing linseed oil and walnut oil and a preparation method thereof. Background technique [0002] Flaxseed, commonly known as flaxseed, is the seed of the herbaceous plant flax. Flaxseed is rich in a variety of substances that are beneficial to human health, such as rich oil and protein. In addition, the content of dietary fiber, minerals, lignans, lecithin and vitamins A, B, D, E and other nutrients is also high. The linseed oil extracted from flaxseed is an important source of α-linolenic acid, which is the vegetable oil with the highest content of α-linolenic acid in the world. α-linolenic acid is the basic substance that forms cell membranes and biological enzymes, and plays a decisive role in human health. , is the material basis of human health. α-linolenic acid is the original substance of omega-3 unsaturated fatty acids, which can be metabolized to...
