Problems solved by technology

The disadvantages are 1. The source of calcium and collagen is not clear, and the cost of animal bone calcium is relatively high, while the chemical calcium source is mainly synthesized from inorganic drugs, which is not clean and environmentally friendly; 2. The description of the synthesis process is too general, and there is no clear definition of collagen and calcium. the solution

[0016] Example Collagen Chelated Oyster Calcium Preparation

[0017] The oyster shells are washed, dried and pulverized, then ashed at 550°C to obtain ash, which is then used for later use. Pigskin is degreased and hydrolyzed with papain and alkaline protease to obtain collagen, which is set aside. Ash content and the hydrochloric acid of 0.48mol / L fully react and filter to obtain calcium chloride solution with solid-liquid ratio 1: 50 (g / ml), and collagen protein and calcium chloride solution are mixed at 50 with solid-liquid ratio 2: 25 (g / ml). Warm water at ℃ for heating and stirring reaction in a water bath for 30 minutes, centrifuge the reaction solution at 3000r / min for 15 minutes, take the supernatant, slowly heat and concentrate to dryness, add 95% ethanol for separation and purification, the amount added is about 8 times the volume of the concentrated solution , refrigerated at 4°C for more than 8 hours, discarded the supernatant, retained the gel precipitate, washed...

Abstract

The invention provides a method for preparing collagen chelated calcium. Animal skin and shell ash content are used as main raw materials; the animal skin is subjected to enzymatic hydrolysis to form collagen and a shell is ashed to form the ash content; the ash content is subjected to acidolysis to form a calcium chloride solution; temperature is controlled to be within a range from 50 to 60 DEG C under the condition of a water phase; and an economic and practical method with the best chelating effect is implemented by optimizing reaction conditions according to three influence factors, namely a mass ratio of the fed ash content to the fed collagen, reaction time and a pH value through single factor experiments and orthogonal experiments. The prepared collagen chelated calcium has double nutrition of collagen and calcium; and a human body can absorb the collagen chelated calcium better.

Description

technical field [0001] The invention relates to a method for preparing collagen chelated calcium by using animal skins and shells, belonging to the technical field of food science and engineering. Background technique [0002] There are many sources of calcium that humans can eat, but people tend to think of them as waste, such as shells, eggshells, animal bones, and ancient vertebrate bone fossils. There are tens of millions of shell wastes on the coast of the Bohai Sea in my country every year. These wastes not only cannot be used well, but also pose a great threat to the environment. [0003] According to the data released by the Chinese Nutrition Society "Chinese Residents' Dietary Nutrient Reference Intake", the daily calcium intake of infants should be about 300mg, increase to 400mg per day after the age of 5, and reach 800mg per day after the age of 7, and 800mg for adults. The calcium requirement of the elderly increases, 1000mg per day, and the requirement of pregn...
