Background

The essential fatty acids (EFAs) are recognized as functional oils for humans as they possess nutritional and pharmaceutical benefits and can promote whole-body health in different ways.

Scope and approach

This review describes and classifies different types of EFAs, gives an overview of the spray drying process alongside its probable challenges for encapsulation of functional oils. Also, various used wall materials, and the effects of the process conditions on the encapsulation efficiency of functional oils have been discussed. Moreover, it focuses on the spray drying encapsulation of functional oils derived from marine and plant-based sources in recent years (2016-2019), and the fortification of different foods with encapsulated functional oils.

Key findings and conclusions

Protecting EFAs through efficient methods such as spray drying encapsulation and enriching the various foods with encapsulated functional oils is an emerging field, which has drawn lots of attention these days. The wall materials (carriers) and spray drying conditions are two major influential factors that can easily affect the properties of final produced powders.

必需脂肪酸和功能油喷雾干燥封装的最新进展

背景

必需脂肪酸（EFA）具有营养和药学益处，并且可以通过各种方式促进全身健康，因此被认为是人类的功能油。

范围和方法

这篇综述描述和分类了不同类型的EFA，概述了喷雾干燥过程以及其对功能油封装的挑战。另外，还讨论了各种使用的壁材料，以及工艺条件对功能油包封效率的影响。此外，它着重于近年来（2016-2019年）对海洋和植物来源的功能油进行喷雾干燥封装，以及使用封装的功能油强化各种食品的方法。

主要发现和结论

通过喷雾干燥封装等有效方法保护EFA，并用封装的功能油丰富各种食品是新兴的领域，近来引起了很多关注。墙壁材料（载体）和喷雾干燥条件是两个很重要的影响因素，它们很容易影响最终生产的粉末的性能。
