Abstract

The encapsulation by spray drying is a common method of encapsulation on the food industry. Many biopolymers are described on the literature as wall materials for this purpose. As different wall materials are applied on spray drying, it is necessary to know their physicochemical characteristics. In view of the different applications for this technology, the objective of the present study is to discuss the physicochemical characteristics of several wall materials used in encapsulation of bioactive compounds by spray drying for human consumption. Among all biopolymers make blends of carbohydrate-based and protein-based biopolymers seems to be the better way to encapsulate bioactive compounds, especially when using vegetable proteins in view of reach a less allergenic product.

摘要

喷雾干燥封装是食品工业常用的封装方法。许多生物聚合物在文献中被描述为用于此目的的壁材料。由于在喷雾干燥中应用不同的壁材，因此有必要了解它们的理化特性。鉴于该技术的不同应用，本研究的目的是讨论用于通过喷雾干燥封装生物活性化合物供人类食用的几种壁材料的物理化学特性。在所有生物聚合物中，碳水化合物基生物聚合物和蛋白质基生物聚合物的混合物似乎是封装生物活性化合物的更好方法，尤其是在使用植物蛋白以减少过敏性产品时。
