Insects, especially crickets, have been proposed as a novel source of nutrients in human nutrition since they possess bioactive molecules, including high protein content, lipids, chitin, vitamins and minerals. In this work, the nutritional and functional properties of a novel Italian spray-dried (SD) cricket powder were evaluated. The powder was characterized by physico-chemical properties (morphology, size distribution, solid state, thermal profiles, and surface zeta potential), and antioxidant properties. Moreover, preclinical properties (cytocompatibility and pro-inflammatory immune response) were assessed. The powder was characterized by microparticle structure with bulges and rough surfaces, showing distinctive antioxidant properties. The preclinical results suggested that the SD crickets were biocompatible towards Caco-2 and macrophages without immune response, representing an interesting material for the food industry that could provide health benefits in addition to the basic nutritional value of traditional foods.
昆虫，尤其是蟋蟀，已被提议作为人类营养中一种新型营养来源，因为它们含有生物活性分子，包括高蛋白含量、脂质、几丁质、维生素和矿物质。在这项研究中，对一种新型意大利喷雾干燥（SD）蟋蟀粉的营养和功能特性进行了评估。该粉末通过物理化学性质（形态、尺寸分布、固态、热特性和表面zeta电位）以及抗氧化特性进行了表征。此外，还评估了临床前特性（细胞相容性和促炎免疫反应）。该粉末具有带有凸起和粗糙表面的微粒结构，表现出独特的抗氧化特性。临床前结果表明，SD蟋蟀对Caco-2细胞和巨噬细胞具有生物相容性且无免疫反应，这使其成为食品工业中一种有趣的材料，除了传统食品的基本营养价值外，还能带来健康益处。
