Collagen fiber quality judgment method

Abstract

The invention relates to a collagen fiber quality judgment method, and belongs to the technical field of collagen detection. The method comprises the following steps of: (1) taking treated and extracted collagen fibers, performing mixing and kneading, carrying out moisture detection, then conducting calculating according to a moisture detection result, supplementing ice water into a collagen fibercluster, and uniformly mixing and kneading the substances; (2) carrying out centrifugal treatment on the collagen fiber cluster; taking out the product and measuring moisture at the upper end and thelower end, and if moisture has no difference, indicating that the fiber water absorption capacity is strong; if the lower moisture is higher than the upper moisture, indicating that the water absorption capacity is weak; and (3) detecting the surface viscosity of the collagen fiber cluster: detecting the surface viscosity of the fiber cluster, and under the condition of the same moisture, the smaller the viscosity is, the better the moisture is bound by the fibers, and the better the opening degree of the collagen fiber bundle is; if collagen fibers are damaged, the water absorption capacitybecomes poor, and the surface viscosity is high. The method is scientific, reasonable, easy and convenient to operate and low in cost, and can better guide production by rapidly judging the quality ofthe collagen fibers.

Description

technical field

[0001] The invention relates to a method for judging the quality of collagen fibers, belonging to the technical field of collagen detection. Background technique

[0002] Collagen casings are woven from collagen fibers, and the extraction of collagen fibers from cowhide is very important in the entire production process. Collagen fibers are bundled in the dermis. The pre-treatment of the skin not only removes albumin, globulin and mucin in the fibrous interstitium, but also disperses the collagen fiber bundles to make the obtained collagen fibers fine. Braided collagen casings have smoother surface, more uniform texture and more stable quality.

[0003] How to judge whether the collagen fiber bundles are evenly opened, has not found a method suitable for large-scale production. In scientific research, transmission electron microscopy can be used to see the dispersion state and size of collagen fibers, but it is time-consuming, costly, and complicated to ope...
