Embodiment 1

[0021] A kind of preparation method of the citrus dietary fiber with antiallergic effect is carried out according to the following steps:

[0022] (1) Grinding of citrus peels: using citrus peels as raw materials, soaking in clean water, washing, crushing, and setting aside;

[0023] (2) Extraction of dietary fiber: extract the pulverized material by immersing it in a hydrochloric acid solution with a pH value of 1.5, the extraction temperature is 85°C, and the extraction time is 2 hours; after leaching, filter and collect the extract; the extract is vacuum Concentrate to one-third of the original volume; then add an appropriate amount of ethanol until the ethanol concentration in the solution reaches 70% for precipitation, and the precipitate is dried at 60°C until the water content reaches 9%, and then crushed to obtain dietary fiber powder;

[0024] (3) Compounding: 10 grams of tea polyphenols and 10 grams of proanthocyanidins are added to every 100 grams of dietary fiber p...

Abstract

The present invention relates to the technical field of dietary fiber preparation, specifically to an antiallergic citrus dietary fiber preparation method and a product thereof. The method comprises: (1) crushing citrus peel residue, (2) extracting dietary fibers, and (3) compounding and other steps. According to the present invention, characteristics that citrus soluble dietary fibers can be provided for inhibiting hyaluronidase and removing free radicals to carry out immunoloregulation are utilized to compound with nature plant extracts having a certain antiallergic activity, such that the obtained product has good antiallergic activity, wherein the nature plant extracts comprise tea polyphenol and proanthocyanidins; the product is the functional component extracted from the nature plant, does not provide toxic-side effects for human body, has an immunoloregulation function, and is suitable for long-term use; and the production process is simple, mass production can be achieved, and economic values and utilization values of the citrus peel residue can be substantially increased.

Description

technical field [0001] The invention relates to the technical field of preparation of dietary fiber, in particular to a preparation method of citrus dietary fiber with antiallergic effect and its product. Background technique [0002] Dietary fiber (dietary fiber, DF) is a carbohydrate or its analogue that has anti-digestive properties and cannot be digested in the small intestine, including some indigestible polysaccharides, oligosaccharides, and other plant associates, according to their solubility Can be divided into water-soluble dietary fiber (soluble dietary fiber, SDF) and insoluble dietary fiber (insoluble dietary fiber, IDF) two categories. Water-soluble dietary fiber includes the storage and secretion of certain plant cells and microbial polysaccharides. Research on the physiological function of dietary fiber is also relatively active at home and abroad, and a large number of data have reported that dietary fiber is effective in the treatment of diabetes. [1] , p...
