The current problem is that the application of collagen derived from livestock is restricted in areas where people believe in Islam and Muslims live together. At the same time, due to the outbreak and prevalence of infectious diseases such as mad cow disease and foot-and-mouth disease in recent years, people are concerned about collagen derived from livestock. The safety of collagen has cast great doubts
However, due to the low gel strength of fish skin collagen, its development and application are limited, making the biological material with high potential value into waste

Embodiment Construction
[0007] Freshwater fish (bighead carp, crucian carp, tilapia, etc.) fish skin collagen is formulated into an aqueous solution with a concentration of 0.5-1.5% (weight percent concentration, the same below), and 1-1.5% prepared in advance is added to the solution sucrose aqueous solution, stirred evenly, and left to react for 1 to 2 hours.
[0008] Since collagen is a macromolecular colloidal substance, adding carbohydrates can enhance its hydration and increase the stability of its intermolecular hydrogen bonds, thereby enhancing its gel strength. The present invention improves the gel strength of fish skin collagen by adding carbohydrates.
[0009] The carbohydrate sucrose in this embodiment can be replaced with other carbohydrates such as algin, agar or xanthan gum, and the effect is similar.

Abstract
The invention provides a method for modifying freshwater fish skin collagen by using carbohydrate which comprises, charging water solution of carbohydrate into the water solution of fresh water fish skin collagen, agitating homogeneously, stewing for reaction 1-2 hrs, the carbohydrates can be sucrose, algin, agar agar or xanthans, the aqueous solution concentration is 1-1.5%. The invention can be applied to increase the fresh water fish skin collagen gelatin strength by one time, and high safety can be achieved.
Description
technical field [0001] The present invention relates to a method for modifying freshwater fish skin collagen with carbohydrates. Background technique [0002] Collagen is the main protein component of all connective tissues (skin, tendons, ligaments, cartilage, etc.) in animals. Because collagen has many excellent properties, it has a wide range of uses, and its application fields involve medicine, food, daily cosmetics, photography, etc. Especially the application in medicine and food industry is more eye-catching. In the field of medicine, in addition to surgical dressings, hemostatic sponges, surgical sutures, and hemostatic agents, foreign researchers mainly focus on the use of collagen to prepare collagen injections that can expand human soft tissues, collagen-based drug delivery systems, Alternative materials for skin, bone, cardiovascular, esophagus, and trachea, etc., while domestic research and clinical application are still in their infancy. In the food industry...
