Process for separating and extracting natural ferulic acid with content not more than 98% from wastes in rice bran oil processing

Abstract

The invention discloses a process for separating and extracting natural ferulic acid with the content not more than 98% from wastes in rice bran oil processing. The process is characterized in that the wastes generated in the rice bran oil processing method are used as raw materials; the process comprises the following steps of: washing by using alcohol, saponificating and filtering, acidifying and filtering, dissolving by using alcohol and filtering, refining by using ion exchange resin, decoloring, concentrating, pumping and filtering, and drying by vacuum to obtain the white powder product with the natural ferulic acid content not more than 98%. The invention has the advantages of easy obtainment of raw materials, utilization of wastes, simple and process, high purity of product by more than 98%, and industrial production.

Description

technical field The invention relates to the extraction of natural ferulic acid, in particular to a process for separating and extracting natural ferulic acid with a content greater than or equal to 98% from rice bran oil processing waste. Background technique Ferulic acid is one of the derivatives of cinnamon acid. There are two types, cis and trans. The cis is a yellow oil, and the trans is a white to slightly yellow powder. It generally refers to the trans. The relative molecular mass is 194.19, and the melting point is 174°C. Ferulic acid has anti-platelet aggregation, inhibits the release of platelet 5-hydroxytryptamine, inhibits the generation of platelet thromboxane A2 (TXA2); enhances the activity of prostaglandins; removes nitrite, oxygen free radicals, and peroxynitroso; antibacterial, anti-inflammatory, Anti-tumor, anti-mutation; enhance human immune function, enhance human sperm vitality and motility, etc. It can be used as the basic raw material of drugs for ...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to provide a kind of raw material that is easy to obtain and extract process for the problem that the rice bran oil processing waste containing natural ferulic acid precursor is discarded, and the output and quality of natural ferulic acid cannot meet the needs. Simple and reliable, the purity of the extracted natural ferulic acid is up to 98%, and the process of separating and extracting natural ferulic acid from the waste of rice bran oil processing can be carried out in industrial production
