Siraitia grosvenorii cellulose sugar with low glycemic index and preparation method thereof

Abstract

The invention discloses siraitia grosvenorii cellulose sugar with low glycemic index and preparation method thereof. The preparation method comprises the following steps: 1) preparing siraitia grosvenorii, adding water for extraction, cooling the extracted feed liquid to 50-60 DEG C, adding protease for enzymolysis, and filtering after enzyme deactivation to obtain the filtrate, an extracting solution, and loading the extracting solution on a macroporous resin column, and collecting the effluent, then eluting the effluent with 50-70% ethanol after column loading is completed, collecting the eluent, recovering ethanol, and drying the eluent to obtain a momordica grosvenori component A; (2) adding yeast into the effluent for fermentation, adding water into the fermented feed liquid, and uniformly stirring the liquid, filtering the liquidand collecting filtrate, then adding ethanol into the filtrate until the ethanol content is greater than or equal to 80%, collecting the precipitate, and drying the precipitate to obtain a fructus momordicae component B; and 3) uniformly mixing the momordica grosvenori component A, the momordica grosvenori component B, supplementary cellulose and a flavoring agent according to a ratio, granulating the mixture, and drying the mixture to obtain the momordica grosvenori beverage. The siraitia grosvenorii cellulose sugar prepared by the method disclosed by the invention is low in micromolecule sugar component content and high in water-soluble dietary fiber content.

Description

technical field [0001] The invention relates to deeply processed products of Luo Han Guo, in particular to a low-glycemic index Luo Han Guo fiber sugar and a preparation method thereof. Background technique [0002] Luo Han Guo (Siraitia grosvenorii) is a perennial rhizome plant of Cucurbitaceae Luo Han Guo. It is a unique economic and medicinal plant in my country and a traditional specialty in northern Guangxi. The fruit has high nutritional value and is rich in vitamin C (400-500 mg per 100 grams of fresh fruit), glycosides, fructose, glucose, protein, lipids, etc. [0003] Dietary fiber refers to polysaccharides and lignin that cannot be decomposed by enzymes in the human digestive tract. It is indispensable for a healthy diet and plays an important role in maintaining the health of the digestive system. It is reflected in: the absorption of water in the digestive system increase the volume of food in the intestinal tract and stomach, which can increase the feeling of s...

AI Technical Summary

Problems solved by technology

Although the glycemic index of the beverage described in this invention is low, due to the high content of glucose, fructose and total sugar in Luo Han Guo (Qi Yiping, etc., "Chemical Composition and Application Research of Luo Han Guo Fruit", Fujian Medical Journal, the 23rd volume in 2001 5), and these sugars are all water-soluble substances, which are directly retained in the beverage, resulting in a high content of small molecule sugars such as glucose and fructose in the beverage
