| Comparative example 4 | 45 | 46.1 |
Compared with example 1, in comparative example 1, the content of phospholipid in the sesame oil product prepared by using an oil mixer without a zirconium phosphate coating is higher. Comparative examples 2-4 where sesame oil extraction was not performed according to the extraction process disclosed in the present application, the oil yield was low. Comparing example 1 with comparative example 1, in example 1, the blending and oil stirring are carried out by using the stirring machine containing the zirconium phosphate coating, so that the prepared product has lower phospholipid content, and no additional degumming treatment is needed, thus the sesame oil processing process is simpler, and the process cost of the sesame oil processing process is reduced. Compared with the example 1, in the example 6, the slurry mixing and oil stirring are completed by using the oil stirring pot after the zirconium phosphate coating is regenerated, the phospholipid content of the prepared product is low, and the zirconium phosphate coating can be regenerated and reused.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
