Infant formulas (IFs) are the key nutritional source for infants who cannot be breastfed. There is currently a growing interest in these sensitive products in order to control their quality and to design their composition with regard to nutritional balance. In a context of sustainable development and increasing growth of the world population, it seems essential to search for alternative to animal protein in food today. Plant proteins offer interesting nutritional and functional benefits thanks to the latest improvement through research and development. In this context, five model IFs were developed with identical composition, except that 50% of the proteins were either whey proteins in the "milk-reference IF", pea, faba bean, rice or potato proteins in the four "plant IFs" tested. The IFs were evaluated using an in vitro static gastro-intestinal model simulating infant conditions. The protein hydrolysis degree (DH) and the amino acid bioaccessibility (AAB) were used as indicators of protein digestibility. Results showed that both DH and AAB were very similar between the milk-reference IF, pea and faba bean IFs, but significantly lower for the rice and potato IFs. This study provides new insights into the impact of protein sources on IF digestibility.
婴儿配方奶粉（IFs）是无法母乳喂养的婴儿的主要营养来源。目前，人们对这些敏感产品越来越感兴趣，以便控制其质量，并在考虑营养平衡的情况下设计其成分。在可持续发展和世界人口不断增长的背景下，寻找食品中动物蛋白的替代品似乎至关重要。植物蛋白通过研究和开发的最新进展，提供了有趣的营养和功能益处。在这种情况下，开发了五种模型 IF，除了 50%的蛋白质分别是乳清蛋白（在“牛奶参考 IF”中）、豌豆、蚕豆、大米或土豆蛋白（在测试的四种“植物 IF”中）外，它们的组成完全相同。使用模拟婴儿条件的体外静态胃肠模型评估 IF。蛋白质水解度（DH）和氨基酸生物利用度（AAB）被用作蛋白质消化率的指标。结果表明，在牛奶参考 IF、豌豆和蚕豆 IF 之间，DH 和 AAB 非常相似，但大米和土豆 IF 则显著较低。这项研究提供了有关蛋白质来源对 IF 消化率影响的新见解。
