To analyze crude protein, crude fat, crude ash, crude fiber, amino acids, fatty acids, and minerals in insect-based dog foods and to evaluate their compliance with nutritional guidelines.
Proximate analysis, mineral analysis, amino acid profiling, and fatty acid composition analysis were conducted from November 27, 2023, through February 2024 on 18 commercially available insect-based dog foods formulated for all-life-stage or adult dogs.
Proximate analysis results revealed that all 18 pet foods met the Association of American Feed Control Officials guidelines. However, discrepancies were observed between the values listed on the packaging and those measured in 7 foods. Mineral analysis showed that while all foods met the Association of American Feed Control Officials guidelines for magnesium, discrepancies were found in calcium, phosphorus, zinc, iron, and copper content, with several samples failing to meet recommended levels. Additionally, 2 foods exceeded the recommended maximum ratio for certain fatty acids. Black soldier fly larvae-based foods contained higher levels of lauric and myristic acids compared to other insect-based foods.
Insect-based dog foods show promise as sustainable protein sources, but discrepancies in mineral content and fatty acid ratios highlight the need for both stricter regulation and better enforcement of existing guidelines to ensure nutritional adequacy for dog health and accurate labeling.
This study provides valuable insights into the nutritional composition of insect-based dog foods, revealing inconsistencies in mineral content and fatty acid ratios. These findings can help the pet food industry develop more nutritionally consistent insect-based diets.
分析以昆虫为原料的犬粮中的粗蛋白、粗脂肪、粗灰分、粗纤维、氨基酸、脂肪酸和矿物质，并评估其是否符合营养指南。
于2023年11月27日至2024年2月，对18种为全生命周期犬或成年犬配制的市售昆虫基犬粮进行了近似分析、矿物质分析、氨基酸谱分析和脂肪酸组成分析。
近似分析结果显示，所有18种宠物食品均符合美国饲料管理官员协会的指南。然而，在7种食品的包装列出的值与实测值之间存在差异。矿物质分析表明，虽然所有食品的镁含量均符合美国饲料管理官员协会的指南，但在钙、磷、锌、铁和铜含量方面存在差异，有几个样品未达到推荐水平。此外，2种食品的某些脂肪酸含量超过了推荐的最大比例。与其他昆虫基食品相比，黑水虻幼虫基食品的月桂酸和肉豆蔻酸含量更高。
以昆虫为原料的犬粮有望成为可持续的蛋白质来源，但矿物质含量和脂肪酸比例的差异凸显了需要更严格的监管以及更好地执行现有指南，以确保犬类健康的营养充足和准确标签。
本研究为以昆虫为原料的犬粮的营养成分提供了有价值的见解，揭示了矿物质含量和脂肪酸比例的不一致。这些发现有助于宠物食品行业开发营养更一致的昆虫基犬粮。
