Embodiment Construction

[0029] The present invention will be described in further detail below through specific examples.

[0030] Take 1.0kg of bitter melon powder, add 8.0L of water and stir to form a slurry, add 4.5% (w%) hydrochloric acid dropwise to the slurry until the pH value is 4.2±0.2, heat to 85°C±5°C for extraction for 3 hours, cool to room temperature after extraction . Adjust the pH of the slurry to 3.5 ± 0.2 with 4.5% (w%) hydrochloric acid, add 40,000 international units (specific activity) cellulase per kg bitter melon powder and add 40,000 international units (specific activity) pectinase per kg bitter melon powder Add 40,000 International Units (specific activity) of cellulase and 40,000 International Units (specific activity) of pectinase in the same ratio, stir well, maintain the pH to 3.5±0.2, and enzymatically hydrolyze at 48°C±2°C 90min. After enzymatic hydrolysis, heat to 100°C for 10 minutes to inactivate the enzyme, cool down to room temperature, and use 500W-5000W ultras...

Abstract

The invention discloses a balsam pear extract and preparation thereof. The extract liquid is made from extraction using fruit of cucurbit balsam pear as raw material. The extraction process includes using water as the solvent, and extracting the balsam pear extract liquid by zymohydrolysis, ultrasonic processing or the like. The balsam pear extract liquid is in light yellow or yellow, contains active substance such as balsam pear saponins, balsam pear polypeptides and active polysaccharide. The process is simple and fast, easy for industrial production, with nutritious extract, without environment pollution, and having low cost. The balsam pear extract has evident function of blood glucose and blood lipid lowering.

Description

technical field [0001] The invention relates to a raw material of food and health products and a preparation method thereof, in particular to a preparation method of bitter melon extract. Background technique [0002] Bitter gourd, also known as brocade litchi, toad, grape, bitter gourd, red sheep, is a vine herb of Cucurbitaceae Bitter gourd. Bitter gourd is bitter and cold in nature. It is one of people's favorite melon vegetables. [0003] Chinese Patent Document No. CN1209155C discloses a preparation method of bitter gourd containing hypoglycemic ingredients. The bitter gourd is deseed and refined, treated with pectinase, cellulase or hemicellulase, and the pulp residue is removed by filtration and centrifugation , and then the impermeable off-white insoluble matter A was separated by microfiltration, and the clear liquid was separated by nanofiltration to obtain component B. The preparation contains saponin, protein and polyphenol oxidase for lowering blood sugar. ...
