Abstract

The invention discloses pitaya pericarp dietary fiber powder, belonging to the field of functional food additives. The high activity dietary fiber powder is prepared by drying, crushing and sieving the pitaya pericarp. The pitaya pericarp dietary fiber powder is characterized in that: the dietary fiber powder comprises no less than 69 % of dietary fibers, proper amount of vegetable protein, and low content of vegetable oil and is rich in phenols; the content of soluble dietary fibers is very high, and the ratio of the soluble dietary fibers to the insoluble dietary fibers is good; the test results show that the dietary fiber powder has high antioxidative activity, outstanding water-keeping ability, oil-keeping ability, swelling property, dialysis retardation index of glucose and other physical and chemical activities; and the dietary fiber powder can be used as a functional food additive which enhances the dietary fiber content of food, and has health care functions of enhancing the moistening intestines, relaxing bowel, satisfying appetite, reducing fat, resisting oxidation, preventing cancer and the like.

Description

technical field [0001] The invention relates to a dietary fiber powder of pitaya peel, which belongs to the field of food technology and functional food additives. Background technique [0002] Dietary fiber (Dietary Fiber, DF) is a general term for plant polysaccharide polymers that can be combined with lignin and other non-sugar compounds, divided into water-soluble dietary fiber (Soluble Dietary Fiber, SDF) and water-insoluble dietary fiber (Insoluble Dietary Fiber, IDF) two categories. IDF mainly acts on the intestinal tract to produce mechanical peristalsis, while SDF exerts more metabolic functions, such as affecting the metabolism of available carbohydrates and lipids. [0003] Although dietary fiber cannot be digested and absorbed in the human body, it has a variety of special functions and physiological effects. Studies have shown that dietary fiber has physiological functions such as promoting gastrointestinal motility, inducing the reproduction of beneficial bac...
