Abstract

The invention discloses a method for degumming sesame oil, which is characterized by comprising the following steps: degumming sesame oil crude oil by an ultrasonic-assisted acid process to obtain a product after the acid process degumming; adding a compound enzyme into the product degummed by the acid method, treating for 55-60 minutes under the condition that the ultrasonic power density is 0.6 W / cm < 2 >, heating to 90-100 DEG C, treating for 10-15 minutes, centrifuging for 10-20 minutes at the rotating speed of 8000-10000 / min, and collecting an upper oil layer, so as to obtain the final degummed sesame oil. Aiming at the technical problems that the cold precipitation time of hydratable phospholipids in the sesame oil is too long and non-hydratable phospholipids are difficult to remove, an ultrasonic-assisted acid method degumming process is combined with a subsequent compound enzyme method degumming process, so that the removal time of the hydratable phospholipids and the non-hydratable phospholipids in the sesame oil is short, and the removal rate is high.

Description

Technical field [0001] The invention belongs to the field of grease processing, and is specifically involved in a process of sesame oil deletion. Background technique [0002] The preparation method of sesame oil is mainly the water generation and crushing method after high temperature and fried seeds. Although the sesame sesame oil produced by these methods is rich in fragrance, but because the sesame oil is high-temperature fried seed and high temperature oil, the sesame oil is deep However, the transparency is not good, especially the impurities such as phospholipids such as phospholipids, the heating test of sesame oil is unqualified, and a floc in the oil, etc., it is necessary to pass a certain refining treatment, which can be used as high quality finished sesate oil. [0003] Sesame oil will have turbidity under low temperature or long-term placement conditions and precipitate, and the main component of the precipitate is made of triglyceride, phospholipid, protein, and sm...
