Abstract: The physical properties of the raw materials used to produce foods for special medical purposes intended for infants need to be considered in the process of formulation design. In order to facilitate the formulation design and rapidly determine the amount of the major raw materials with complex chemical composition used to produce foods for special medical purposes intended for infants, some physical properties of these materials and auxiliary materials such as granularity, tap density and angle of repose were investigated. Moreover, the granularity, tap density, angle of repose and particle size distribution of commercial produced products from the formulations developed in this study were also analyzed. The results showed that all the products had identical physical properties, indicating these formulations can meet the requirements of commercial applications without modification.

Key words: foods for special medical purposes for infants; physical properties; formulation design

摘要： 探究特殊医学用途婴儿配方食品实践中，从原料物性角度进行配方设计。通过对原、辅料的颗粒度及振实密度、休止角等物性进行研究，有助于便捷的配方设计，快速确定成分复杂和用量较大的原料量。对该配方商业化试制成品的颗粒度、振实密度、休止角和粒径分布进行分析，结果表明：不同批次成品具有相对一致的物性，表明该方法设计的配方不需进行纠偏即能满足商业化生产的需要。
