Infancy may represent a sensitive window for establishing food preferences that could affect the individual's long-term potential to establish healthy eating patterns. Our study was based on the hypothesis that preserving the natural flavor of the ingredients of commercially prepared complementary foods would increase the acceptance of new foods, especially vegetables. Frozen vegetable-based meals for infants were developed to preserve the natural taste of the ingredients better than sterilization of meals in jars. In a 3-month randomized, controlled intervention study, 51 infants were fed either frozen menus (intervention group) or commercial sterilized meals in jars (control group) on at least 5 days per week. Then the acceptability of a known vegetable-based puree was tested in comparison to an unknown puree, measuring the quantities consumed and also the mother's assessment of the infants' liking. In conclusion, the results of this study clearly indicated that infants fed vegetable-based frozen meals for 3 months accepted a new vegetable better than infants fed sterilized commercial meals in jars.

婴儿期可能是建立食物偏好的敏感窗口，可能会影响个人建立健康饮食模式的长期潜力。我们的研究基于这样一个假设，即保留商业制备的辅食成分的天然风味会增加对新食物的接受度，尤其是蔬菜。婴儿冷冻蔬菜餐的开发目的是比罐装食品的灭菌更好地保留成分的天然味道。在一项为期 3 个月的随机对照干预研究中，51 名婴儿每周至少有 5 天被喂食冷冻菜单（干预组）或罐装商业消毒餐（对照组）。然后将已知的蔬菜泥与未知的泥进行比较，测试其可接受性，测量消耗量以及母亲对婴儿喜好的评估。总之，这项研究的结果清楚地表明，喂食以蔬菜为基础的冷冻膳食 3 个月的婴儿比喂食罐装无菌商品的婴儿更好地接受一种新蔬菜。
