Spring silkworm "eggs" were originally genetically modified
Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.

According to the person in charge of the company, traditional silkworm cocoons are generally white. In recent years, a small amount of colored cocoons have appeared because silkworms eat color feed. Since last year, the company and Zhejiang University have teamed up to transform the genetics of silkworms to produce genetically modified silkworms that can produce natural colors. At present, the market price of this new type of color silkworm is at least twice as high as that of the traditional silkworm cocoon.
