Abstract

The invention relates to an acid-proof type microalgae DHA oil microcapsule powder and a preparation method thereof. The acid-proof type microalgae DHA oil microcapsule powder is prepared from 12.6%-30.3% of core materials and 69.7%-87.4% of wall materials, concretely comprising the following active ingredients in percentage by weight: 12.5%-30.0% of microalgae DHA oil, 0.1%-0.3% of antioxidant, 25.0%-50.0% of whey protein, 3.0%-8.0% of food emulsifier, 20.0%-54.4% of sweetener, 4.40%-8.0% of hydrophilic colloid, and 0.60%-1.20% of acidity regulator. The prepared acid-proof type microalgae DHA oil microcapsule powder has good acid-proof property, and can be applied in a food system of an acid water system with pH of more than or equal to 3.5, the oxidization speed of microalgae DHA can be effectively reduced and delayed, the activity of the microalgae DHA can be maintained, the stability of microalgae DHA in acid water system food can be enhanced, and the shelf life of the acid water system food with microalgae DHA can be prolonged.

Description

technical field

[0001] The invention belongs to the technical field of food production, and relates to an acid-resistant microalgae DHA oil microcapsule powder and a preparation method thereof. Background technique

[0002] DHA (docosahexaenoic acid), also known as docosahexaenoic acid, commonly known as brain gold, is a very important long-chain polyunsaturated fatty acid (LCPUFA), which belongs to the n-3 series of polyene fatty acids. An important member of the polyunsaturated fatty acid family. DHA is a main element for the growth and maintenance of nervous system cells. It is an important component of the brain and retina. Its content in the human cerebral cortex is as high as 20%, and it accounts for the largest proportion in the retina of the eye, accounting for about 50%. DHA helps For the vision and eye development of adolescents and children, it is mainly manifested in the following aspects: (1) promote brain development and memory; (2) promote the functional deve...
