This study aimed at exploring the possibility of substituting powdered milk (PM) with migratory locust powder (MLP) as a cheap and sustainable alternative protein source in peanut-based ready-to-use therapeutic foods used in treatment of malnutrition. The migratory locust is a wide spread and underutilised high protein edible insect. Peanut-based ready-to-use therapeutic foods (RUTFs) were formulated according to the MSF/UNICEF 2013 nutritional standards. Milk powder was substituted with MLP at 5-30% levels. RUTF containing 30% milk powder was used as the control. Nutritional, antioxidant and antinutrients composition of the insect-enriched RUTFs were compared with RUTF containing milk powder only and a standard. The protein content of the insect-enriched RUTFs ranged from 19.58-26.38% exceeding the MSF/UNICEF minimum standard for protein. RUTF with 10% PM and 20% MLP had the highest (p < 0.05) mineral contents. All formulations had more thiamine (vitamin B1) than the recommended level of 0.5 mg/100 g. Niacin (Vitamin B3) was the most abundant vitamin in the formulations with considerable amounts of vitamin D and E. All MLP-enriched RUTFs met the FAO 2011 standard requirements for amino acids for children aged six months to three years. Therapeutic food with 30% MLP had the highest radical scavenging ability against DPPH, and iron chelating activity. Levels of phytate and tannin were below the tolerable limits. Therefore, MLP can be used as a low-cost substitute for milk powder in producing ready-to-use therapeutic foods.
本研究旨在探索用飞蝗粉（MLP）替代奶粉（PM）作为廉价且可持续的替代蛋白质来源的可能性，用于治疗营养不良的花生基即食治疗性食品中。飞蝗是一种广泛分布且未得到充分利用的高蛋白可食用昆虫。花生基即食治疗性食品（RUTFs）是根据无国界医生组织/联合国儿童基金会2013年的营养标准配制的。奶粉被MLP以5%-30%的水平替代。含有30%奶粉的RUTF用作对照。将富含昆虫的RUTFs的营养、抗氧化和抗营养成分与仅含奶粉的RUTF和标准品进行比较。富含昆虫的RUTFs的蛋白质含量在19.58%-26.38%之间，超过了无国界医生组织/联合国儿童基金会的蛋白质最低标准。含有10%PM和20%MLP的RUTF矿物质含量最高（p < 0.05）。所有配方的硫胺素（维生素B1）含量均高于推荐水平0.5 mg/100 g。烟酸（维生素B3）是配方中含量最丰富的维生素，还有相当数量的维生素D和E。所有富含MLP的RUTFs均符合粮农组织2011年针对6个月至3岁儿童的氨基酸标准要求。含有30%MLP的治疗性食品对DPPH的自由基清除能力和铁螯合活性最高。植酸盐和单宁的含量低于可耐受限度。因此，MLP可作为奶粉的低成本替代品用于生产即食治疗性食品。
