天然防腐剂连翘精油的研究进展

连翘是一种具有很高利用价值的药食两用的植物,不仅有抗菌、强心、利尿、镇吐等药理作用,而且还可以应用于食品、化工、医疗保健等方面,具有很大的科研价值。其精油主要是从连翘的种子中提取的一种挥发性活性物质,具有多种生物学功能,如抗氧化、抑菌消炎、抑制病毒等。随着人们对食品安全性的日益重视,近年来以天然防腐剂代替化学合成防腐剂成为一种发展趋势,因而人们热衷于开发安全、天然的防腐剂。连翘作为一种新型的天然食品防腐剂,因其具有价格低廉,对食品风味影响小等特点,已成为了科研领域研究的热点。本文着重介绍了连翘精油的提取方法、包合工艺的研究、不同产地连翘精油的成分差异以及其抑菌和抗氧化作用,并对其应用前景进行了展望,为以后的应用研究提供一定的理论基础。

Research progress on a natural preservative - Forsythia suspense essential oil

Forsythia suspense is a higher exploitation value plant because of its edible and clinical function.It has some pharmacological actions including bacteriostasis,cardiotonic,diuresis and antemetic,and can be applied to many fields such as food,chemical industry,and medical care.F.suspense essential oil is extracted from the seeds and has various biological functions,such as anti-oxidation,bacteriostasis and anti-phlogosis,anti-virus.As people pay more and more attention to food safety,natural preservative replacing chemical synthetic preservative has become a developing trend.As a new type of natural preservative,F.suspense has become a hot research project for its characteristic of low price and little effect on food flavor.This paper mainly reviews the extraction methods and conditions,components different from different places;bacteriostasis and anti-oxidation of F.suspense essential oil from.The future application is also discussed.The new trends of research on the essential oil from F.suspense are depicted to provide theoretical basis in the application of the essential oil.
