Development of Fermented Cricket Paste and Its Characteristic Comparison with Traditional Fermented Shrimp Paste (terasi)

The demand for sustainable protein has increased interest in edible insects, and fermentation can improve the sensory and nutritional profiles of novel foods. This study aimed to develop a fermented cricket paste using a method analogous to traditional shrimp paste and evaluate the physiochemical, nutritional, microbiological, and sensory properties. Both pastes were produced via a biphasic fermentation protocol and subsequently analyzed for their physicochemical, nutritional, microbiological, and sensory properties including consumer acceptance testing in a chili paste. The cricket paste showed a comparable protein content, but higher in carbohydrates and lower in fat. It also showed enhanced stability and safety, with a significantly lower level of histamine (2.37 ppm) compared with shrimp paste (50.51 ppm). While the microbial profiles were broadly similar, the cricket paste had a lower lactic acid bacteria community. Sensory analysis revealed distinct profiles, with the cricket paste characterized by a dark color, coarse texture, nutty/earthy aroma, bitter, and less umami. Despite these differences, consumer liking for chili pastes made with either product was statistically identical. Cricket paste is therefore a safe, stable, and nutritionally advantageous alternative that is highly acceptable to consumers when used as a culinary ingredient.
