Embodiment 1

[0039] S1. Take pomelo peel, add 1.5% cellulase and 1.5% pectinase according to the weight of pomelo peel, add water at 50°C, the weight ratio of water and pomelo peel is 25:1, high shear Dispersing and emulsifying machine 10000r / min under the treatment of 10min, enzymatic hydrolysis for 1.5 hours, to obtain enzymatic hydrolysis liquid, take a part of the enzymatic hydrolysis liquid, leaching, to obtain a polysaccharide content of 9.49%

[0040] S2. Take the enzymolysis solution obtained from S1, add ethanol so that the concentration of ethanol in the solution is 45~55%, ethanol analysis at a temperature of 25°C-4°C, centrifuge, and centrifuge to obtain a precipitate 1 and a supernatant 1, and the obtained precipitate Object one is that the yield of a crude polysaccharide is 13.12%, the purity of the polysaccharide in the a crude polysaccharide is 42.2%, and the yield of a polysaccharide after purification is 5.6%,

[0041] S3. Add ethanol to the supernatant obtained in step S...

[0044] 1. Materials

[0045] The honey pomelo was collected from the pomelo garden in Meizhou, and the honey pomelo with the same variety, size, uniform fruit color, basically the same maturity, no mechanical damage, no disease and pest infestation was selected as the test material. After the peel is cut into thin slices, it is dried in a constant temperature drying oven, and it is ground into powder by a pulverizer for later use. Reagents were analytically pure glucose, absolute ethanol, propylene glycol, 5% phenol, concentrated sulfuric acid, deionized water, chloroform, n-butanol, activated carbon, etc. were purchased from Guangzhou Yima Biotechnology Co., Ltd. Pectinase: Tianjin Enzyme Preparation Factory; Cellulase: Shanghai Boao Biotechnology Co., Ltd.

Abstract

The present invention provides a method for extracting honey pomelo pomelo peel polysaccharides and its products and applications thereof. A preparation method for honey pomelo pomelo peel tobacco humectant is provided. The honey pomelo peel is used as a material, and high-speed shear emulsification is combined with a compound enzyme two The polysaccharides from pomelo peel were extracted by first-time wall-breaking method, and the polysaccharides from pomelo peel were prepared by temperature-variable osmotic precipitation with organic solvents. The molecular weight distribution differences of the polysaccharides were studied by gel chromatography. The determination of the molecular weight of polysaccharides of different grades shows that there are significant differences in the molecular weight of polysaccharides graded by different solvents. Among them, the weight average molecular weight of peak ① of a crude polysaccharide is 24100 Da, the weight average molecular weight of peak ① of b crude polysaccharide is 11700 Da, and the weight average molecular weight of peak ① of c crude polysaccharide is 11700 Da. The weight average molecular weight of peak ① is 2130 Da. It shows that the lower the ethanol concentration, the larger the molecular weight of the precipitated polysaccharide. The optimal moisture retention concentration of pomelo polysaccharide is 1.5g / 100Ml. When different solvents are selected, the moisturizing effect of pomelo polysaccharide is different, and the moisture retention of water-soluble pomelo polysaccharide is significantly higher than that of alcohol-soluble pomelo Polysaccharides, in general, are higher than currently used humectants such as propylene glycol.

Description

technical field [0001] The invention relates to the field of polysaccharide extraction, more specifically, to a method for extracting and grading pomelo pomelo peel polysaccharides and the application of the product. Background technique [0002] Pomelo belongs to Rutaceae citrus and is one of the most popular fruits. Guangdong Meixian pomelo is the leading product of the "three high" agricultural strategy in Guangdong Province. At present, Meizhou golden pomelo has been cultivated for nearly a hundred years. The total area of ​​the city is 400,000 mu, and the output is 300,000 tons. Above, the output of pomelo in the province is as high as 400,000 tons, and it is the largest production base of pomelo in the country. In 1995, it was named the "Hometown of Golden Pomelo" by the Organizing Committee of the first batch of 100 Chinese Specialty Hometowns. At present, the city has a total area of ​​300,000 mu and an output of more than 300,000 tons. It is the largest production ...
