    The objective of this study was to compare the nutritional quality of larvae and pupae of the silkworm (Bombyx mori). A proximal analysis was performed on: energy (kcal/kg), minerals (%), protein (%), and in vitro digestibility of larvae and pupae of Bombyx mori on wet and dry bases. One hundred (100) larvae and 100 pupae produced under laboratory conditions in July and August 2013 were used. Analysis was performed one month after collection in the laboratory of the Department of Animal Nutrition and Biochemistry of the Faculty of Veterinary Medicine of the National Autonomous University of Mexico. According to statistical analysis, on dry bases, the pupae showed higher energy (4231.89 kcal/kg), mineral (6.25%), protein (64.31%), and fat extract (20.63%) content; as compared with larval energy (4115.79 kcal/kg), mineral (5.02%), protein (62.60%), and fat extract (12.90%) content. Silkworm larvae and pupae are ingredients for the production of cattle rations and the preparation of conventional foods that are rich in protein, fat, and minerals.

    Sericin applications: a globular silk protein
    (Universidad del Valle, 2016-07-08) Barajas Gamboa, Jaime A.; Serpa Guerra, Angélica M.; Restrepo Osorio, Adriana; Álvarez López, Catalina
    (Eng) Sericin is a protein found in silk. This one has different biological functions such as oxidation resistance, antibacterial and antimicrobial activity, and solar ultraviolet radiation (UV) protection, easy absorption and moisture release, inhibition of tyrosine and kinase’s activity and cellular additivity, anticoagulants and anticancer properties, and also promotes cell growth and wound healing. In this scientific review article will be reviewed general characteristics of both the fiber of silksilk worm Bombyx mori, and specifically of silk sericin (physico-chemical composition, structural properties and extraction methods). The potential use of sericin in food, drug and cosmetics applications will be also detailed, due to its valuable bioactive properties.
