Nutritional Content and Microbial Quality of Complementary Foods Produced from Blends of Orange-Fleshed Sweet Potato and Edible Insects

Abstract

Objectives: Improved formulations of complementary foods (CFs) with animal-source foods (ASFs) is an eminent strategy to improve infant nutrition, but they are expensive and not readily available in many food insecure settings which are a haven of edible insects. Hence, we developed orange-fleshed sweet potato (OFSP) based CFs supplemented with Cricket or palm weevil larvae (PWL), examined its nutritional content and microbial quality for infant feeding. Methods: OFSP roots were sourced from local farmers, peeled, sliced, steam cooked and mechanically dried into OFSP flour. Cricket powder and PWL paste were obtained from commercial producers, steam cooked, and mechanically dried into Cricket/PWL flours. OFSP flour was mixed with either Cricket/PWL flours in the ratios of 100:0 (control), 85:15, 70:30, and 50:50 and used to produce ready-to-eat CFs. The CFs were evaluated for nutrient composition and microbial contamination using standard methods. ANOVA followed by Dunnett's test was used to compare all the formulations to the control.
