Effects of Edible Insect Enrichment of Meat-Based and Meat Analogue Products on the Nutritional Composition, Techno-Functional Properties, and Acceptability to Consumers: A Systematic Review

BACKGROUND: Meat-based and meat analogue products are commonly consumed foods for protein nourishment across the globe. These food products are promising carrier media that can be targeted for the delivery of edible insect products as a strategy to overcome food neophobia. This systematic review aimed to evaluate the effect of edible insect enrichment on the nutritional, physicochemical, techno-functional, and acceptability of meat-based and meat analogue products for consumers. METHODS: A systematic search for relevant articles was conducted on the databases PubMed, ScienceDirect, and Scopus on 5 November 2025. A total of 25 papers were included. RESULTS: Edible insects and larvae from mealworms, crickets, grasshoppers, silkworm pupae, and superworms were commonly used to enrich meat-based and meat analogue products. Commonly reported meat products were sausages from pork and beef, pork patties, meat emulsion, and frankfurters. Soya flour was commonly used for meat analogue formulation. CONCLUSIONS: Acceptable edible insect incorporation is matrix-dependent, with conventional meat products generally tolerating low substitution levels (≈2.5-10%) before sensory and structural quality declines, whereas meat analogue systems can accommodate substantially higher inclusion (≈10-40% and, in some cases, up to ~60%). However, heterogeneity in formulations and sensory evaluation methods restricts direct comparison across studies.
