摘要

本综述将讨论迄今为止已优化的将皂料酶解成富含游离脂肪酸的混合物的方法,以便为目前在工业水平上将皂料转化为副产品酸油(或油素,即从原料植物油中去除的游离脂肪酸,溶解在残余的甘油三酯中)的过程提供可持续的替代方法。将进一步描述用于生产生物柴油和精细化学品(表面活性剂、增塑剂和添加剂)的皂料或相应的酸油的生物催化操作,并特别关注在连续流模式下进行的过程。在工业脂肪酶生产中,皂料作为碳源的增值也将被考虑。

Enzymatic Methods for the Manipulation and Valorization of Soapstock from Vegetable Oil Refining Processes
The review will discuss the methods that have been optimized so far for the enzymatic hydrolysis of soapstock into enriched mixtures of free fatty acids, in order to offer a sustainable alternative to the procedure which is currently employed at the industrial level for converting soapstock into the by-product known as acid oil (or olein, i.e., free fatty acids removed from raw vegetable oil, dissolved in residual triglycerides). The further biocatalyzed manipulation of soapstock or of the corresponding acid oil for the production of biodiesel and fine chemicals (surfactants, plasticizers, and additives) will be described, with specific attention given to processes performed in continuous flow mode. The valorization of soapstock as carbon source in industrial lipase production will be also considered.
