However, despite its importance in food preparation, an optimal sacrifice method for insects is under research. Therefore, this study sought a suitable sacrifice method for mealworm (<i>Tenebrio molitor</i>), a representative edible insect. Mealworms were sacrificed via freezing, sonication, blanching, and roasting and processed into powder, the predominant form in food industries. Freezing and sonication increased the free amino acid content but significantly decreased water-adhesion capacity and acceptance scores. Blanching and roasting produced mealworm powders with higher overall acceptance scores (3.33±1.06 and 3.53±1.20, respectively) than freezing and sonication (2.00±1.00 and 2.33±1.07, respectively; p<0.05). Moreover, blanching yielded higher water- (1.84± 0.01 g/g) and oil- (1.53±0.07 g/g) adhesion capacities than roasting (1.29±0.02 and 1.21± 0.14 g/g, respectively; p<0.05). Therefore, blanching was deemed a suitable sacrifice method that potentially enhances mealworm powder usability in the food industry. Additionally, to expand the application of blanching-sacrificed mealworms, we cooked them via steaming, boiling, panfrying, and deep-fat frying and verified their characteristics. Moist-heat cooking methods (steaming and boiling) conferred chewy/juicy textures and steamed-grain/mushroom odors to mealworms; conversely, dry heat-cooked (panfrying and deep-fat frying) mealworms exhibited a crispy texture, roasting odor, and savory taste. Among the four cooking methods, panfrying yielded the highest volatile compound content, with 2-methylbutanal and isobutyraldehyde being the most abundant. Our findings provide insights into optimizing sacrifice and cooking methods to improve the quality and sensory traits of mealworms and their derived products.</p>","PeriodicalId":12459,"journal":{"name":"Food Science of Animal Resources","volume":"45 3","pages":"855-870"},"PeriodicalIF":4.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12246911/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cultured meat production, scaffolds play an important role as structural and biochemical supports for cell adhesion, proliferation, and differentiation. The selection of biomaterials directly influences cellular processes and consequently shape the texture, flavor, and overall quality of the cultivated meat. This review provides a comprehensive overview of biomaterials employed in cultured meat scaffolds, encompassing sources such as animals, plants, algae, and microorganisms. The strengths and limitations of each biomaterial type are critically analyzed to guide scaffold fabrication strategies. Furthermore, potential applications are explored to address the constraints of individual biomaterials. Animal-derived biomaterials improve cell adhesion and biocompatibility by imitating extracellular substrates but are limited by high cost and low mechanical strength. Although plant-derived biomaterials are cost-effective and biodegradable, their mechanical strength and biocompatibility should be enhanced through chemical modification or combination with other biomaterials. Algae-derived biomaterials provide gelling properties but lack cell-binding sites and mechanical stability. Microbial-derived biomaterials provide high mechanical strength, while the lack of nutritional value and cell-binding sites limits their application in scaffold fabrication. Each biomaterial possesses unique properties, presenting both advantages and disadvantages. By leveraging their strengths, individual biomaterials can serve as effective sources for scaffold construction.
