Abstract

The invention discloses a preparation method of a cod skin collagen peptide copper chelate. The preparation method is characterized by comprising the following steps of: weighing a certain amount of cod skin collagen peptide and copper sulfate, putting the weighed cod skin collagen peptide and copper sulfate into a beaker, adding 100ml of distilled water, fully mixing and dissolving, and heating in a water bath. The cod skin collagen peptide copper chelate prepared by the method is simple in process method and less in environmental pollution, can obtain good economic and social benefits, and promotes the development of the deep processing industry of marine aquatic products.

Description

Technical field [0001] The present invention relates to a method for preparing a trout-skin collagen peptide copper chelate. Background technique [0002] Copper is one of the trace elements necessary for animals, participating in hemoglobin synthesis and activation and activation in animals. The lack of copper will affect the use of animals to iron, thereby producing anemia. Copper is a necessary trace element necessary for animal, there is an important nutritional function, and there is a strong impact on the immune system and antioxidant stress of animals. However, the biological utilization efficiency of different copper sources is different. The total utilization rate of copper elements is low, but it promotes the growth effect of young animals, so the case of supercodes of copper elements in feed is more common, resulting in problems such as high copper excretion, pollution environment, and resource waste in animal feces. Therefore, looking for a new type of copper source, ...
