Abstract Acheta domesticus is one of the most promising reared insects because of their attractive nutritional profile and lower feed conversion ratio than other animals. Hence, it has potential to increase the nutritional value of food products. The aim of this study was to evaluate the effects of enrichment, with different quantities of Acheta domesticus powder, on protein content, physicochemical properties, and extrusion parameters of extruded corn snacks. Extrudate characteristic parameters were fitted against Acheta domesticus concentration and these represented equations were very closed with the experimental data according the obtained adjusted R2. Using Acheta domesticus powder increased the protein content of extrudates showing suitable extrusion parameters. Extruded snack enrichment with 12.5 and 15% of Acheta domesticus powder are foods classed as “source of protein” according to European law n. 1924/2006. However, high Acheta domesticus concentration in mixtures resulted in low expansion and less crunchy extrudates, but low risk of molecular damage by molecules solubilised in water, gave more stability due to lower values of water solubility index. To maintain typical extrudate parameters, the use of 7.5% Acheta domesticus is recommended for extruded snack mixtures.

添加 Achetadomesticus（家蟋蟀）对挤出产品的蛋白质含量、颜色、质地和挤出参数的影响。

摘要 家蚕是最有前途的饲养昆虫之一，因为它们具有诱人的营养特征和比其他动物更低的饲料转化率。因此，它具有提高食品营养价值的潜力。本研究的目的是评估用不同数量的 Acheta 家兔粉进行浓缩对挤压玉米零食的蛋白质含量、理化特性和挤压参数的影响。根据获得的调整后的 R2，将挤出物特征参数与 Acheta domesticus 浓度拟合，这些方程与实验数据非常接近。使用 Achetadomesticus 粉末增加了挤出物的蛋白质含量，显示出合适的挤出参数。12 挤压膨化零食。5% 和 15% 的 Achetadomesticus 粉是根据欧洲法律第 1924/2006。然而，混合物中高浓度的 Acheta domesticus 导致低膨胀和更少松脆的挤出物，但溶解在水中的分子造成分子损伤的风险低，由于水溶性指数值较低，因此稳定性更高。为了保持典型的挤出物参数，建议在挤出的零食混合物中使用 7.5% 的 Achetadomesticus。
