Clanis bilineata larvae are widely consumed in China. In this study, chitooligosaccharides were prepared from C. bilineata larvae skin by demineralisation, deproteination, washing, drying, deacetylation, hydrolysis using commercial alpha-amylase, filtration, setting the preparation at approximately 15% (w/v), precipitation with 6 volumes of ethanol, and drying at 60 C for 2 h. The optimal hydrolysis conditions were determined as follows: pH 5.5; temperature, 55 C; enzyme amount, 40. mg/(g chitosan); reaction time, 4 h. The Fourier transform infrared spectra revealed that chitooligosaccharides with a degree of polymerisation in the range of 2-8 were the main component of the resulting product, with the chitooligosaccharide content and yield being 95.8% and 96.2% (w/w), respectively. The resulting product showed high antibacterial activity compared with the original chitosan.
