Abstract

Protein malnutrition remains a significant challenge in many Nigerian households. House crickets, are a rich nutritional alternative protein source. This study aimed to assess the shelf life of house cricket meals under varying temperature and storage conditions, employing a modified logistic mathematical model. Adult and nymph house crickets were procured from Olabisi Onabanjo University, Ago-Iwoye, Nigeria. Samples underwent different drying processes, analyzed for microbial load and shelf life across various storage periods. Modified logistic model was used for shelf-life calculation. Periodic samplings revealed distinct microbial counts for the samples at different intervals. Sun-dried samples showed an average microbial load (2430.0 CFU/g), increasing slightly (2442.5 CFU/g) after thirty days. Oven-dried samples exhibited lower initial counts, ranging (272.5 CFU/g -287.5 CFU/g), with a slight increase observed after ninety days. Growth rates varied between adult and nymph samples, with adults showing rates of (0.400 CFU/g, 0.086 CFU/g, and 0.055 CFU/g), compared to nymph (0.525 CFU/g, 0.079 CFU/g, and 0.064 CFU/g). The maximum shelf life determined was 117 days at 80°C. House cricket meals demonstrate promising shelf life under controlled temperature conditions, suggesting potential for long-term storage and distribution. Further research is warranted to optimize processing methods and explore broader applications of house crickets as a sustainable protein source in Nigeria.
