Researchers compared the yellowing behavior, chemical composition, X-ray structure, and disscolution properties of silk fibroin and sericin produced by silkworms reared on an artificial diet with those of silkworms reared on a mulberry leaf diet. An experiment raised silkworms of an artifical diet (A), consisting primarily of tofu cake, or a mulberry leaf diet (M) for an entire instar. Amino acid composition and X-ray diffraction patterns of a and M fibroins were almost identical. The dissolution rate of the A sericin was higher than that of the M sericin. Although yellowing of M samples was significant after irradiation with ultraviolet light, it was scarcely evident ofr a samples. Researchers attributed the difference in yellowing to the large quantity of nucleotide compounds in the hot water soluble fraction of the A samples. 11 refs.
