Problems solved by technology

However, the bitter taste of the grape seeds itself and the fermentation taste produced during the fermentation of wine will affect the taste
One method is to use solvent method or macroporous resin adsorption method to produce relatively pure proanthocyanidins first, and then add them to the beverage system. On the one hand, this method will greatly increase the cost, and on the other hand, the solvent or resin debris Residues will have a certain impact on the safety of beverages

Abstract

The invention provides a grape seed proanthocyanidins health beverage and a preparation method. The beverage is prepared by the following steps of: extracting leftover grape seeds in a wine plant, performing combined membrane separation technology on the extract to obtain clarified, deastringented and proanthocyanidins-enriched purified liquid, and adding water and various flavoring agents into the purified liquid in a ratio to obtain the product. The beverage does not have the astringent taste of the grape seed per se and yeast taste generated in the wine fermentation process, and also fully keeps the medicinal values of the grape seed.

Description

technical field [0001] The invention relates to a method for preparing a health drink, in particular to a method for preparing a grape seed proanthocyanidin health drink by extracting and purifying leftover grape seeds from a winery. Background technique [0002] Recent studies have shown that natural plant extracts containing polyphenols exhibit strong antioxidant capacity and have beneficial effects on human health. Among them, proanthocyanidins, a flavonoid compound, have attracted increasing attention. After years of research and development, proanthocyanidins have been approved by people for their superior antioxidant capacity and free radical scavenging activity, and they have a wide range of uses in the fields of medicine, health care, and food. [0003] Proanthocyanidins are widely found in plants, especially in the seed coats of grape seeds. Each part of grapes contains phenolic chemical components to varying degrees. With the deepening of research, many researcher...
