Edible insects constitute a potential source of alternative proteins as a food supplement. The present study aimed to investigate the chemical composition, energy and nutritional values, the digestibility and functional properties of Carbula marginella (Thunberg) and Cirina butyrospermi (Vuillet) defatted flour, protein concentrates, and isolates. Carbula marginella has shown the highest content of protein (41.44%), lipid (51.92%), calcium (33.92 mg/100 g) and sodium (185.84 mg/100 g) while the highest contents of carbohydrate (34.54%), ash (4.77%), iron (31.27 mg/100 g), magnesium (150.09 mg/100 g), and potassium (1277 mg/100 g) have been observed for C. butyrospermi. Linoleic (30.23%), palmitic (27.54%), oleic (26.41%) and stearic (8.90%) acids were the most dominant fatty acids found in C. marginella. Cirina butyrospermi was characterized by high levels of oleic (27.01%), stearic (21.02%), linolenic (20.42%), palmitic (13.06%), and linoleic (8.01%) acids. Protein and essential amino acid contents of the protein isolates in both insect species were 1.7–2 times higher than that of their defatted flours. The protein isolate of C. marginella exhibited the highest protein digestibility (87.63%), while the highest fat absorption capacity (8.84 g/g) and foaming capacity (48.40%) have been obtained from the protein isolate of C. butyrospermi. These findings indicate that the protein concentrates and isolates of C. marginella and C. butyrospermi have great potential for industrial applications.

脱脂面粉、蛋白质浓缩物和分离物的化学成分、能量和营养价值、消化率和功能特性,来自 Carbula marginella(半翅目:五翅目)和 Cirina butyrospermi(鳞翅目:Saturniidae)

食用昆虫构成了替代蛋白质作为食品补充剂的潜在来源。本研究旨在调查 Carbula marginella (Thunberg) 和 Cirina butyrospermi (Vuillet) 脱脂面粉、蛋白质浓缩物和分离物的化学成分、能量和营养价值、消化率和功能特性。Carbula marginella 的蛋白质(41.44%)、脂质(51.92%)、钙(33.92 mg/100 g)和钠(185.84 mg/100 g)含量最高,碳水化合物(34.54%)、灰分( 4.77%)、铁 (31.27 mg/100 g)、镁 (150.09 mg/100 g) 和钾 (1277 mg/100 g) 已观察到 C. butyrospermi。亚油酸 (30.23%)、棕榈酸 (27.54%)、油酸 (26.41%) 和硬脂酸 (8.90%) 是在 C. marginella 中发现的最主要的脂肪酸。Cirina butyrospermi 的特点是油酸 (27.01%)、硬脂酸 (21.02%)、亚麻酸 (20.42%)、棕榈酸 (13.06%) 和亚油酸 (8.01%) 含量高。两种昆虫中分离蛋白的蛋白质和必需氨基酸含量比脱脂面粉高 1.7-2 倍。C. marginella 的蛋白质分离物表现出最高的蛋白质消化率 (87.63%),而从 C. butyrospermi 的蛋白质分离物获得最高的脂肪吸收能力 (8.84 g/g) 和发泡能力 (48.40%)。这些发现表明 C. marginella 和 C. butyrospermi 的蛋白质浓缩物和分离物具有巨大的工业应用潜力。两种昆虫中分离蛋白的蛋白质和必需氨基酸含量比脱脂面粉高 1.7-2 倍。C. marginella 的蛋白质分离物表现出最高的蛋白质消化率 (87.63%),而从 C. butyrospermi 的蛋白质分离物获得最高的脂肪吸收能力 (8.84 g/g) 和发泡能力 (48.40%)。这些发现表明 C. marginella 和 C. butyrospermi 的蛋白质浓缩物和分离物具有巨大的工业应用潜力。两种昆虫中分离蛋白的蛋白质和必需氨基酸含量比脱脂面粉高 1.7-2 倍。C. marginella 的蛋白质分离物表现出最高的蛋白质消化率 (87.63%),而从 C. butyrospermi 的蛋白质分离物获得最高的脂肪吸收能力 (8.84 g/g) 和发泡能力 (48.40%)。这些发现表明 C. marginella 和 C. butyrospermi 的蛋白质浓缩物和分离物具有巨大的工业应用潜力。40%) 已从 C. butyrospermi 的蛋白质分离物中获得。这些发现表明 C. marginella 和 C. butyrospermi 的蛋白质浓缩物和分离物具有巨大的工业应用潜力。40%) 已从 C. butyrospermi 的蛋白质分离物中获得。这些发现表明 C. marginella 和 C. butyrospermi 的蛋白质浓缩物和分离物具有巨大的工业应用潜力。
