A kind of dragon fruit stem powder not easy to absorb moisture and preparation method thereof

Abstract

The invention provides stable pitaya stem powder difficult in moisture absorption and a production method thereof.The pitaya stem powder is produced by mixing pitaya stem slurry, beta-cyclodextrin, maltodextrin, lecithin, konjac glucomannan and water-soluble chitosan through formula I, performing vacuum spray drying or vacuum freeze drying and adding anti-caking agent, and the granularity of the pitaya stem powder is not smaller than 60 mesh.The production method includes raw material processing, swelling, mixing, homogenizing, performing vacuum spray drying or vacuum freeze drying, adding anti-caking agent, crushing, sieving and the like.The pitaya stem powder has the advantages that the moisture absorption rate of the pitaya stem powder is lowered evidently, and the pitaya stem powder is high in stability, capable of being added to food made of flour to serve as raw material, rich in nutrition, bright in color, capable of avoiding waste of a large amount of pitaya stems, capable of increasing the overall utilization value of pitaya plants and capable of increasing economic benefits.

Description

technical field [0001] The invention relates to the technical field of pitaya stem processing, in particular to a stable and non-hygroscopic pitaya stem powder and a preparation method thereof. Background technique [0002] Pitaya stems contain a variety of phytosterols, such as dandelion sterol, brassicasterol, β-sitosterol, ergosterol, stigmasterol, etc. Sterols are a class of substances with cyclopentane perhydrophenanthrene as the skeleton (also known as steroid nucleus), which exist in free and combined forms in nature. Sterols can be divided into three categories: animal sterols, plant sterols, and fungal sterols. Phytosterols are a class of physiologically active substances that can inhibit the body's absorption and biochemical synthesis of cholesterol, promote the degradation and metabolism of cholesterol, and can be used to prevent and treat coronary atherosclerosis-like heart disease. Secondly, phytosterols also have the functions of inhibiting platelet aggregati...
