Problems solved by technology

However, when DHA microcapsule powder is applied to liquid beverages, it is prone to the problems of sinking and oxidation. Although the microemulsion prepared by nanotechnology can slow down the oxidation process due to its embedding characteristics and the produced micellar system, it still has Due to the existence of oxygen, light and heat, it will lead to split reaction, which will reduce the retention rate of DHA

Abstract

The present invention relates to the technical field of functional beverages and more particularly to an algal oil DHA liquid beverage and a preparation method thereof. The algae oil DHA liquid beverage comprises the following components in mass concentration: 0.5-5 g / L of an algal oil DHA preparation, 10-200 g / L of green tea, 0.2-5 g / L of bioflavonoids, 0.1-3 g / L of vitamin C, 0-10 g / L of a foodadditive and the balanced deionized water. A cold soaking technology is used to extract tea polyphenol components in the green tea; and at the same time, the green tea is reasonably combined with theantioxidants of the vitamin C, bioflavonoids, etc. to produce the algae oil DHA liquid beverage. The algal oil DHA liquid beverage solves an oxidation problem of DHA algae oil applied in the beverages, helps to improve mouthfeel and nutritional value, and extends a shelf life.

Description

technical field [0001] The invention relates to the technical field of functional beverages, in particular to an algae oil DHA liquid beverage and a preparation method thereof. Background technique [0002] Cis-4,7,10,13,16,19-Docosahexaenoic Acid (DHA), commonly known as brain gold, is an important member of the omega-3 unsaturated fat family and is important for maintaining the nervous system The important fatty acid components in cells and visual cells play an important role in the normal performance of human physiological functions and the prevention and treatment of various diseases. Since the DHA algae oil derived from marine microalgae was approved as a new resource food by the Ministry of Health in March 2010, it has gradually been applied in the fields of prepared milk, edible oil, health food, cake, beverage and so on. [0003] The molecular structure of DHA contains six unsaturated double bonds, which are easily oxidized under conditions such as oxygen, light, an...
