蛋白基乳液模板法构建油凝胶的研究进展Research progress of construction of oleogels by protein based emulsion template method

Abstract

传统塑性脂肪带来健康问题，液态油固化成为构建零反式、低饱和脂肪酸塑性脂肪替代品的新策略。蛋白质是优质的食品营养组分，是来源广泛的可再生资源，具有独特的界面特性。为扩大蛋白资源的应用范围及促进功能性油脂的开发，对蛋白质的结构化及蛋白基乳液模板法构建油凝胶（结构化油脂）研究进展进行了综述，同时介绍了蛋白基乳液模板法构建的油凝胶的应用。蛋白质在一定条件下可作为凝胶剂固化液态油；蛋白基乳液模板法构建油凝胶具有安全性高、对环境污染小等优点。采用蛋白基乳液模板法构建的油凝胶可应用于替代传统塑性脂肪、荷载生物活性成分方面。 The traditional plastic fats cause health problem, and solidification of liquid oil is considered as a new strategy to obtain plastic fat with zero-trans and low-saturated fatty acids. As a high quality nutrition component of food, protein is a renewable resource with a wide range of sources, and it has unique interface properties. To expanding protein applications and development of functional fats, the research progress of structuring protein and constructing oleogels by protein based emulsion template method was reviewed. The application of oleogels constructed by protein based emulsion template method was also summarized. Under certain conditions, protein could be used as a gelling agent to solidify liquid oil to prepare oleogels. Constructing oleogels by protein based emulsion template method has the advantages of high safety and low environmental pollution. The oleogels constructed by protein based emulsion template method could be used to replace traditional plastic fats and load bioactive ingredients.
