Abstract

The invention provides a preparation method and an application of citrus pomace ultramicropowder rich in pectin and total flavones. The method comprises the steps of carrying out pre-drying, drying, pre-grinding and grinding to prepare the citrus pomace ultramicropowder. The pectin content and the total flavone content of the citrus pomace ultramicropowder prepared with the method are 80% and more than 85% of fresh citrus pomace respectively, so that effective active substances such as pectin, total flavones and the like in the fresh citrus pomace are reserved to a great extent; and the operation is simple and the added value is high. The citrus pomace ultramicropowder prepared with the method is small in particle size, so that a solution is transparent when the citrus pomace ultramicropowder is dissolved in water and other solvents, and the citrus pomace ultramicropowder can be well applied to food processing, medicine research and cosmetic configuration.

Description

technical field [0001] The invention relates to the technical field of superfine powder preparation, more specifically, to a preparation method and application of citrus peel superfine powder rich in pectin and total flavonoids. Background technique [0002] Citrus peel is the waste produced during the consumption or food processing of citrus. The water content of the citrus peel can reach more than 80%, and the citrus peel is rich in nutrients such as protein, fat, carbohydrate compounds and trace elements, wherein the content of pectin in the citrus peel exceeds 20%. [0003] Pectin has a wide range of uses. In dairy product processing, pectin is usually used as gelling agent, thickener, stabilizer, suspending agent, emulsifier and flavor enhancer, etc., such as fruit pulp, jelly, candy, Stabilizer for baby food, ice cream and fruit juice, egg yolk emulsifier and thickener; in the pharmaceutical industry, pectin is a good antidote and preventive agent for metal poisoning ...
