Problems solved by technology

The acid hydrolysis method requires high temperature, and the hydrolysis reaction lacks specificity. In addition to hydrolyzing glycosidic bonds, it can also destroy other groups on the mother nucleus, resulting in the reduction or even disappearance of blueberry anthocyanin activity, and acid hydrolysis will pollute the environment. The application effect is not ideal

Abstract

The invention relates to a preparation method of blueberry anthocyanins with high bioavailability. The method comprises the following steps: preparation of blueberry anthocyanin solution, glycosidase-catalyzed conversion of blueberry anthocyanin, membrane separation of blueberry anthocyanin conversion product, separation of blueberry anthocyanin in permeate, high bioavailability Drying and preservation of blueberry anthocyanins. Beneficial technical effects are: (1) Enzyme-catalyzed reaction is carried out by using a membrane reactor integrating reaction and separation, which not only improves the use efficiency of enzyme, reduces production cost, but also continuously discharges reaction products, reduces or even eliminates reaction The inhibitory effect of the product on the enzyme improves the speed of the catalytic reaction; (2) The integrated membrane reaction system, reverse osmosis system, and extraction system prepare blueberry anthocyanins with high bioavailability, which is suitable for industrialization; (3) The present invention obtains High bioavailability The bioavailability of blueberry anthocyanins is higher than 60%, which has higher health care value and wider practical application fields.

Description

technical field [0001] The invention belongs to the field of deep processing of food functional components, and in particular relates to a preparation method of blueberry anthocyanins with high bioavailability. Background technique [0002] Blueberry anthocyanin is a flavonoid compound extracted from blueberry (also called lingonberry) fruit with 2-phenylbenzopyran as the core. It consists of delphinidin, cyanidin, paeoniflorin, There are 5 kinds of anthocyanin aglycones in mallow pigment and morning glory anthocyanin, and anthocyanin glycosides formed by linking each anthocyanin aglycon with glucose, galactose, arabinose, acetylglucose, acetylgalactose, and acetylarabinose composition. The antioxidant activity of blueberry anthocyanins is V C 20 times of V E It has physiological functions such as anti-oxidation, anti-aging, anti-virus, anti-cardiovascular disease, promotion of resynthesis of retinoid, and protection of eyesight. For this reason, blueberry anthocyanins a...
