Nutritional characteristics, microbial loads and consumer acceptability of cookies enriched with insect (Ruspolia differens) meal

Abstract:

Utilization of Ruspolia differens Serville as functional food ingredient is rapidly gaining popularity. This study evaluated the nutrient quality, microbial safety and consumers’ acceptability of cereal-based cookies fortified with various processed products of R. differens meals. Cookies fortified with blanched, boiled, and toasted R. differens meals had higher protein, fat and energy levels, respectively, than the control cookies. Enrichment of cookies with differentially processed R. differens meals had elevated levels of isoleucine and leucine. Omega-3 fatty acid, methyl (9Z,12Z,15Z)-octadecatrienoate, was detected only in cookies prepared from wheat-insect meals blends. Blanched and boiled R. differens meal significantly (p < 0.05) boosted iron (1.70-folds) and zinc (1.12–1.16-folds) contents of the cookies. The cookie products had reduced Enterobacteriaceae, S. aureus, yeast and mould with permissible exposure limits for human consumption. The overall acceptability of insect-enriched cookie product by male and female respondents ranged between 57 and 80%. The survey revealed that the flavour, colour, mouthfeels and texture of the cookie products were important motivation for consumers to accept grasshoppers as a food source. Further research on the flavour of cookie products enriched with grass-hopper meal would be required to increase acceptability to market-driven consumer appealing food products.
