Preparation method of citrus whole fruit superfine powder and citrus whole fruit superfine powder

Abstract

The invention discloses a preparation method of citrus whole fruit superfine powder and citrus whole fruit superfine powder. The preparation method comprises the following steps: the citrus is subjected to ozone cleaning treatment, and then coarse pulverization, wet superfine pulverization, ultrasonic pulverization, enzymolysis, Colloid milling and high-pressure homogenization to obtain whole fruit pulp with a particle size of 5 μm to 15 μm; then vacuum freeze and spray dry the whole fruit pulp to obtain whole fruit superfine powder. The invention effectively solves the problem that macromolecules such as fiber and pectin in the whole fruit peel and seeds of citrus are insoluble in water, realizes the full utilization of citrus, and retains the nutritional components to the greatest extent; realizes superfine powder by using its own pectin The stability in the fruit juice system reduces chemical addition; the use of its own essential oils promotes the effective antibacterial effect of the fruit powder; functional components such as flavonoids, limonoids, and carotenoids enhance the effects of anti-oxidation and anti-inflammation; the obtained citrus is whole The fruit powder has strong aroma, bright color, rich in functional nutrients and good stability.

Description
