Tangerine whole-fruit superfine powder and preparation method thereof

Abstract

The invention discloses a method for preparing tangerine whole-fruit superfine powder and the tangerine whole-fruit superfine powder. The preparation method comprises the following steps: performing ozone washing treatment on tangerines; and sequentially performing coarse grinding, wet-processing superfine grinding, ultrasonic grinding, enzymolysis, colloid grinding and high-pressure homogenizingto obtain whole-fruit pulp having the grain size of 5-15mu m; and performing vacuum freezing and spray drying on the whole-fruit pulp to obtain the whole-fruit superfine powder. According to the preparation method, the problem that fibers, pectin and other macromolecules in peels and seeds of tangerine whole fruits are water insoluble can be effectively solved, complete utilization of tangerines can be realized, and nutritional ingredients can be furthest maintained; the stability of the superfine powder under a juice system can be realized by utilizing the pectin of tangerines; the effects ofoxidation resistance, inflammation resistance and the like can be enhanced due to functional ingredients including flavone, limonin, carotenoid and the like; and the tangerine whole-fruit superfine powder has rich fragrance, bright color, rich functional nutritional ingredients and good stability.
