Popis: s The mulberry silkworm, Bombyx mori, has provided valuable fabrics and foods to humans for > 5000 years. We invented the protocol for processing mature silkworms, which contain various functional substances, into edible steamed and freeze-dried mature silkworm powders (SMSPs). However, previously reported technique could not create powders smaller than 0.1 mm and had problems with loss of product due to large SMSP particles sticking to hammer mill machines during the pulverizing process. To resolve these problems, we invented a new pulverization protocol that could create particle sizes smaller than 0.01 mm. Reduced particle sizes in SMSPs offered several advantages: increased nutrient contents in the nutritional aspect and extended life expectancy and enhanced locomotor activity in the pharmacological aspect. In addition, four SMSPs were enriched with flavonoids, poly-phenols, and vitamins that are known to act as oxidative stress inhibitors in cells and tissues. Nutrient and phytochemical composition analysis results suggested that this is why SMSPs extended healthspans and inhibited onset of Parkinson's disease. Although most nutrient and phytochemical compositions among the four SMSPs were comparable, certain nutrients and chemicals were significantly higher in certain SMSPs. Therefore, further research using these four SMSPs will identify the specific health-promoting effects of each SMSP, resulting in the further development of sericulture and entomology.
