Product prepared by shark cartilage for supplementing calcium and promoting metabolism and development of cartilage and preparation method thereof

Abstract

The invention discloses a product prepared by shark cartilage for supplementing calcium and promoting metabolism and development of cartilage, comprising the following matters according to part by weight, 20-80 parts of shark cartilage organic calcium, 1-20 parts of collagen and 1-20 parts of mucopolysaccharide. The invention also discloses a preparation method of the product prepared by shark cartilage for supplementing calcium and promoting metabolism and development of cartilage. The preparation method of the shark cartilage organic calcium comprises the following steps: curing, acidizing, enzymolysis, deproteinization, crystallization, resin pretreatment, resin exchange, ultra-filtration dehydration, filtrate calcification, dehydration and drying. The preparation method of the collagen and the mucopolysaccharide comprises the following steps: boiling the shark cartilage by water, then crushing and conducting homogenate on the shark cartilage, removing sediments by filtering, adding filtrate with macroporous resin for absorption, then conducting elution by sodium chloride solution, and finally adding ethanol in eluent for settlement. The product has the beneficial effects that calcium is supplemented, the cartilage metabolism is promoted, the cartilage development of children is enhanced, the cartilage injure is repaired, the absorption rate of a human body is high, and the side effect does not exist.

Description

technical field [0001] The invention belongs to health products and a preparation method thereof, and relates to a product prepared from shark cartilage for calcium supplementation and promoting cartilage metabolism and development and a preparation method thereof. Background technique [0002] According to the "Nutrition and Health of Chinese Residents" survey report in 2002, the calcium deficiency in China is still very serious, and the daily calcium intake of residents is 391 mg, which is only equivalent to 41% of the recommended intake. Oxalic acid and dietary fiber in vegetables can also prevent calcium absorption. The eating habits of Chinese residents directly cause 90% of people in our country to be in a state of calcium starvation throughout their lives. At present, a large number of calcium supplement products have emerged in the market, but most of them have problems such as low calcium content and extremely difficult absorption. As an important part of ...

AI Technical Summary

Problems solved by technology

The traditional methods for extracting organic calcium from shark cartilage mainly include alkaline extraction, enzymatic hydrolysis, alkaline extraction, ultrasonic-assisted method and acetic acid extraction. The common alkaline production process still has the defects of low purity and high production cost due to the large amount of ethanol used.
