example 1

[0020] Example 1 takes the extraction of composite collagen from chicken breast cartilage as an example, but the present invention is not only applicable to taking chicken breast cartilage as a raw material. In fact, cartilage tissue of other animals can also be used as a raw material, but because chicken breast cartilage is relatively easy to obtain, it is preferred. Chicken breast cartilage. Please refer to figure 1 As shown, the present invention performs the following operation steps in sequence.

[0021] Step A: take healthy and hygienic chicken breast cartilage as a raw material, add water to the reaction tank until it is completely submerged, and soak for 4 hours; stir and clean the water for 20 minutes and let it go;

[0022] Step B: first add 10 times the amount of water, then add 30% aqueous sodium hydroxide solution to adjust the pH to 11, start stirring, and raise the temperature to 30°C to 35°C for hydrolysis for 4 hours;

[0023] Step C: After the hydrolysis is...

Abstract

The technological process for extracting compound bone collagen from animal soft bone includes the following steps: cleaning, hydrolyzing by using basic aqueous solution, cooling and adding acid, filtering, concentrating, alcohol precipitation, dewatering, drying and packaging so as to obtain the invented product which is low in fat content, high in collagen protein content and contains trace elements of calcium, magnesium and potassium, etc and 19 amino acids. The chondrine content is up to abouve 20%, and the content of harmful substances of lead, arsenic and mercury is less than National Food Safely Standard. Said product can be used for producing several health-care foods, and can be added in various foods, and can be used in domestic chemical industry.

Description

technical field [0001] The invention relates to a processing technology for extracting nutrients from animal tissues, in particular to a processing technology for extracting composite collagen from animal cartilage. Background technique [0002] As we all know, animal cartilage tissue contains a variety of nutrients, especially chondroitin, collagen is the most abundant, but also contains calcium, magnesium, potassium and other trace elements, more than ten kinds of amino acids. In the past, the above-mentioned nutrients in animal cartilage existed in macromolecular complexes, which were extremely difficult to digest and absorb, so they were discarded. Unfortunately, it was also a waste. [0003] Therefore, if we can change its molecular structure through a certain industrial processing extraction process, extract useful substances from animal cartilage tissue, so that the ingredients with nutritional value are highly concentrated and easy to digest and absorb by the human b...
