Abstract

The invention belongs to the technical field of processing food healthy product, and particularly relates to a dragon fruit peel active dietary fiber powder and a preparation method thereof. The preparation method comprises the following steps: performing puffing drying to dragon fruit peels and grinding, soaking the ground dragon fruit peels and extracting water-soluble dietary fiber constituents, filtering and performing enzymolysis to filter residues so as to further improve the content of the water-soluble dietary fiber constituents, performing spray drying to the two filtrates, mixing the filter residues and dragon fruit seeds, and grinding and performing microwave drying; mixing the spray-dried materials with the microwave-dried materials according to a proportion, and performing superfine grinding, thus reducing the particle fineness, and improving the activity of the materials.

Description

technical field [0001] The invention belongs to the technical field of food health product processing, and in particular relates to a dragon fruit peel active dietary fiber powder and a preparation method thereof. Background technique [0002] Dietary fiber (DF) is a general term for plant-based polysaccharide polymers, which cannot be decomposed by human digestive tract enzymes, but because of its ability to improve food quality, reduce food calories, promote intestinal peristalsis, and increase satiety , preventing obesity and intestinal diseases, lowering cholesterol, lowering blood sugar, lowering blood pressure, anti-oxidation and free radical scavenging ability, improving human immunity and other physiological functions, has also become an indispensable substance for the human body, known as the "first" of human beings Seven Nutrients". Dietary fiber is divided into two types: soluble dietary fiber (SDF) and insoluble dietary fiber (IDF). [0003] Insoluble dietary f...
