Use Pangasius skin, basa fish as a cosmetic

Scientists from An Giang Department of Agriculture and Rural Development and Ho Chi Minh City Polytechnic University have successfully separated collagen from pangasius fillet to use in cosmetic production.

According to experts, collagen is simply understood as the main component of connective tissue in the human body, the most common protein in the body (a quarter of the total protein). For skin, in addition to bonding, this substance also creates elasticity. So when we get older, the collagen in the skin is broken, the damage to our skin is loss of elasticity, firmness, rapid flow and formation of wrinkles.

At this time, the skin begins to dry, tan in some areas exposed directly to the sun as the cheekbones, forehead. According to research, collagen extracted from fish skin is much smaller than collagen extracted from other animal species such as pig skin or cow skin, so the collagen permeability of fish is higher.

The scientists used two methods, acetic acid and the use of solvents combined with enzymes. When kept below 39.5 ° C, collagen is not denatured in structure and is easy to store. Currently, the research team is testing technology to extract collagen from skin and bones of tra and basa catfish for use in the food, pharmaceutical and cosmetic industries. If successful, this technology will not only help processing waste from seafood processing plants, reduce environmental pollution but also increase the value of catfish and basa fish.
