Abstract： In the food packaging industry，the color of packages made from collgen （Col） material is relatively single. With the continuous improvement of consumers' requirements for food appearance， giving edible packages some colors to enhance the atractivenessof food appearance has become a research focus. In this study，two kinds of water-soluble natural pigments， namely cochineal（Coc）and betacyanin（Bet），are mixed with collagen solution to make colored collagen membranes，and the effects of the pigments on the properties and color stability of collagen membranes are studied. The results show that compared with pure colagen membrane，the addition of pigments improves the mechanical properties and thermal stability of collagen membranes. In addition，cochineal collagen membrane （ [Coc-Col] ） and betacyanin collagen membrane （Bet-Col） have better UV blocking properties，and can still maintain the original color wellafter light and heat treatment. Colored colagen membranes can help to enrich the existing food packaging market and expand the application of collagen materials in condiment packaging and other fields.
