Abstract

The invention discloses a preparation method and application of a wolfberry extract. The method comprises the following steps: evenly mixing wolfberries with petroleum ethers, performing extraction and solid-liquid separation and distilling a filtrate so as to obtain an extract; performing heat extraction on filter residues twice by adding water, filtering and concentrating a filtrate so as to obtain an extract; mixing the extracts, drying and smashing so as to form fine wolfberry powder of 500 to 700 meshes; evenly mixing the fine wolfberry powder with ethyl alcohol; performing extraction and solid-liquid separation and distilling the filtrate so as to obtain an extract; performing heat extraction on filter residues twice by adding water; filtering and concentrating a filtrate so as to obtain an extract; mixing the extracts, drying and smashing so as to form fine powder of 500 to 700 meshes, thereby preparing the extract product. The method is complete in extraction, high in efficiency and large in economic value. The wolfberry extract can be applied to wine products, soft or solid beverages, flavoring agents and nutritional supplements.

Description

technical field [0001] The invention relates to a preparation method of natural plant fruit extracts, and also relates to the field of functional foods, in particular to a preparation method and application of wolfberry extract. Background technique [0002] Lycium barbarum tastes sweet and nutritious. my country has a long history of medicinal and edible use of wolfberry. As a nutritious food, it mainly includes dried fruit, medicinal food and dishes. In recent years, it has been developed into beverages, alcohol, dried fruit, wolfberry powder, and preserved fruit of wolfberry. and other products are supplied to the market, satisfying the partial demand of the market to varying degrees, but, as a kind of wolfberry with high nutritional value and health care effect, it is far from being integrated into the lives of ordinary people, so that wolfberry cannot be widely used. application to benefit more people. With the improvement of people's living standards, the pursuit of hea...
