Abstract

The application of supercritical technologies as an alternative to conventional methods for encapsulating food compounds is an area of research that can lead to significant innovations in various segments of industrial food processing. The existing supercritical techniques are classified as follows according to the function of the supercritical fluid used in the process: solvent; antisolvent; cosolvent or solute; nebulization compound; extractor and antisolvent techniques. Supercritical carbon dioxide (scCO2) is the substance most widely used for obtaining micro/nanoparticles due to its unique characteristics, and among the existing encapsulation supercritical techniques, those using scCO2 as the antisolvent are more likely to be successful because food compounds are generally less soluble or even insoluble in scCO2. In this context, this review presents and discusses the applications of supercritical processes using scCO2 as the antisolvent for the encapsulation of substances of interest to the food industry.
用超临界技术包封食品化合物:超临界二氧化碳作为抗溶剂的应用
应用超临界技术替代传统的食品化合物封装方法是一个研究领域,可以在工业食品加工的各个环节带来重大创新。现有的超临界技术根据工艺中所用超临界流体的作用分为以下几种:溶剂;antisolvent;助溶剂或溶质;雾化化合物;萃取和抗溶剂技术。超临界二氧化碳(scCO2)由于其独特的特性是获得微/纳米颗粒最广泛使用的物质,而在现有的封装超临界技术中,使用scCO2作为抗溶剂的技术更容易成功,因为食品化合物通常不溶于scCO2,甚至不溶于scCO2。在此背景下,本文介绍并讨论了超临界工艺中使用scCO2作为抗溶剂对食品工业感兴趣的物质进行封装的应用。
