Abstract

The invention discloses a preparation method for nigrum fruit products. The preparation method comprises the steps that immature nigrum fruit in June, or July or August is used as a raw material, washed, squeezed or boiled, then squeezed or dewatered, squeezed and filtered, secondary filter residues and filter liquid are obtained; the secondary filter residues are added with 60-85% ethanol to be extracted for 2-3 times, and extracting solution combining, concentration, pH adjusting, water adding, filtering and drying are conducted, and a nigrum fruit extract is obtained; the filter liquid is concentrated and dried, and nigrum fruit juice powder is obtained; and the nigrum fruit extract and the nigrum fruit juice powder are evenly mixed to be powdery or granular, and the nigrum fruit products are obtained. The preparation method is reasonable in design and simple and convenient to operate, and the content of effective components in the nigrum fruit products is increased; the products obtained through the preparation method are portable, easy to store, can be directly brewed by adding water to serve as a nigrum fruit beverage to be drunk, and can also be reprocessed to be applied to the fields of functional food and health food, and the application ways of nigrum fruit food is broadened.
