Production process of sesamol-rich fragrant sesame oil

Abstract

The invention discloses a production process of sesamol-rich fragrant sesame oil. The production process is characterized by comprising the following steps of: cleaning and removing impurities; soaking and washing; naturally draining and germinating; frying seeds at a high temperature; cooling; grinding into pulp with a stone mill; adding water and stirring; turning oil (shaking oil); skimming oil; and standing and settling to obtain a finished product. The production process has the advantages that the defects of high probability of getting burnt during direct roasting of dry sesame and high probability of producing 3,4-benzopyrene after burning are avoided by soaking the sesame with water, draining and then roasting at the high temperature, the sesame seeds are germinated during washing, soaking and drainage of the sesame, the germinated sesame seeds are roasted at the high temperature and then grease is extracted, the sesamol content in the sesame oil is higher than that of the sesame oil extracted from the ungerminated sesame, sesame pulp has high water absorbing speed and high oil yield speed, the obtained sesame oil has better flavor, the content of vitamin E in the sesame oil extracted from the germinated sesame, which is washed and soaked with water and drained, is higher than that of the sesame oil extracted from the ungerminated sesame, and the oil yield is improved by 1-2 percent compared with that in the prior art.

Description

technical field [0001] The invention belongs to the fields of deep processing of vegetable oils and production of high-quality edible oil, and specifically relates to a production process of sesame oil rich in sesamol, which is a process technology suitable for the production of high-quality sesame oil. Background technique [0002] Sesame is not only rich in oil and protein, but also has good health care and medicinal value. According to the determination results of more than 4,200 sesame resources and varieties by the Institute of Oil Plants, Chinese Academy of Agricultural Sciences, the oil content of sesame is 53.59% on average, and the highest can reach 61.65%; the protein content of sesame is 22.1% on average, and the highest is 29.28% [1] . Sesame oil contains ingredients that are not found in other oils, namely sesame lignans (also known as sesame lignans), and is also rich in tocopherols, namely vitamin E. Lignans and vitamin E in sesame oil are the material basis...

AI Technical Summary

Problems solved by technology

This kind of seed frying process is easy to cause local overheating and burnt sesame, and tritetrabenzopyridine is easy to be produced after burnt, which increases the risk of tritetrabenzopyridine in sesame oil exceeding the standard

In addition, too high temperature may also produce trans fatty acids in the prepared sesame oil, and at the same time, the color of the sesame oil will deepen and the transparency will deteriorate.
