![]() Crude protein (CP) content of freeze and oven-dried mealworms were similar ( p > 0.05), but higher ( p 0.05) for all drying methods. Yellow mealworms (exposed to sun, oven and freeze drying) were later analyzed for their chemical composition and body color. Thus, the core aim of this study was to investigate different drying procedures and their impact on the chemical composition of yellow mealworm larvae. However, the energy costs associated with these methods are usually high for smallholder insect-rearing farmers. To preserve the quality of the yellow mealworm, different drying methods are being explored by farmers and processors. However, it is important to monitor and determine the microbial growth so the final product whether it meets the food safety standard. Oven and freeze-drying strategies can be used to formulate mealworm-based feed and food products without noticeable nutritional changes. It can be concluded that sun drying had the same nutritional composition as freeze and oven drying despite the color changes. ![]() The majority of the essential amino acids were higher in the sun-dried mealworms than both the oven and freeze-dried samples. The color of the sun-dried mealworms changed slightly to brownish this could probably be related to Maillard reaction. The crude protein content of freeze and oven-dried mealworms were similar however, higher than those of the sun-dried samples. ![]() The yellow mealworm samples were gently frozen in a −20 freezer afterwards blanched and exposed to sun-drying, oven-drying, and freeze-drying then were later analyzed for their chemical composition. Thus, the study sought to investigate the different drying procedures and their impact on the chemical composition and body color of yellow mealworm larvae. ![]() ![]() The energy cost of drying mealworms varies according to the drying technique that is used. Insects such as mealworms must be dried to preserve their quality different drying methods have been applied before. Edible insects are rich in nutrients and moisture and this may cause high microbial growth. ![]()
