Extraction technology of randia cochinchinensis volatile oil

Abstract

The invention relates to an extraction technology of a randia cochinchinensis volatile oil, and belongs to the technical field of food processing. The extraction technology comprises following steps:(1) preparing randia cochinchinensis peel powder; (2) preparing volatile oil: adding 10 grams of randia cochinchinensis peel powder into a three-necked flask, carrying out reflux extraction for a while at a room temperature in vacuum, and collecting the distillate; (3) re-extracting: repeatedly extracting the collected distillate by 50 mL of petroleum ether, merging the extracts, transferring theextract to a water bath with a constant temperature of 35 DEG C, and volatilizing the petroleum ether to obtain a light-yellow transparent oily liquid namely randia cochinchinensis volatile oil; and (4) analyzing the components: adopting head-space extraction gas chromatography to analyze the components of the obtained randia cochinchinensis volatile oil. The technology is simple. The content of extracted randia cochinchinensis volatile oil reaches 8.17 k / kg. The main components of the randia cochinchinensis volatile oil are 4-carene, myristicin, terpinolene, limonene, and the like, and the use value is high.
