The nutritional composition and sensory properties of masa produced from rice enriched with edibles insects [grasshopper (Zonocerus variegatus) and caterpillar (Lepidopteran larva)] were evaluated. The rice, grasshopper and caterpillar flour were blended in the ratios of 100:0 (control), 95:5, 90:10, 85:15, 80:20, 75:25 respectively. Sensory attributes, proximate compositions and amino acids profile were determined using standard analytical methods. The result showed that control sample (100% rice-masa) was preferred by consumers with a mean score above 7 in all the sensory parameters considered. Similarly, the result also shows significant (p < 0.05) increase in protein, ash, fibre, and carbohydrate contents while ash and moisture content decrease significantly in the enriched masa. Again, essential amino acid distributions histidine, isoleucine, leucine, methione, phenylalanine, threonine, tryptophan, valine, lysine and the non-essential amino acid arginine, glutamate, cysteine, glycine, proline, serine, alanine, aspartate, tyrosine enriched with 15 and 25% caterpillar increased significantly (p < 0.05). Also, the essential and non essential amino acid contents in samples enriched with 5, 10 and 20% grasshopper were significantly increased (p < 0.05). This study shows that enriching rice-masa with grasshopper and caterpillar has the potential of raising the nutritional status of the snack. Thus, this may be recommended as snack or breakfast meal for school feeding program as well as a possible means in fighting hidden hunger and malnutrition. This research showed that caterpillar and grasshopper used as enriching agents could serve as excellent sources of protein to combat protein-energy malnutrition and supply limiting amino acids to the rice-based masa.
