Problems solved by technology

[0005] CO 2 Although the supercritical process retains the natural substances of pomegranate seed oil, it is difficult to be accepted by consumers due to its inherent pungent acidic smell
At the same time CO 2 Supercritical equipment requires large investment, high technical requirements, and high product costs, making it difficult to scale up
[0006] In the conventional machine pressing process, due to the hard pomegranate seed shell and repeated friction with the pressing chamber, the processing temperature is difficult to control, the oil yield is low, the anisidine value is high, and the isomerization of punicic acid is serious, which greatly affects the product. nutritional value

Abstract

The invention discloses a preparation method of pomegranate seed oil. The method comprises the following steps: taking fresh pomegranate seeds, removing impurities and rotten and bad pomegranate seeds, and grinding to remove 10-40% of pomegranate seed peel; uniformly spreading pure water to the pomegranate seeds subjected to peel grinding to adjust the water content of the pomegranate seeds to 5-15 wt%; squeezing the pomegranate seeds in a squeezer to obtain raw oil, wherein the squeezing temperature is controlled at 40-100 DEG C; and adding a filter aid, which accounts for 0.5-2 wt% of the raw oil, into the raw oil, stirring uniformly, and filtering to obtain the pomegranate seed oil. The preparation method has the advantages of simpleness, favorable effect, fewer impurities in the product, and low production cost, effectively controls the decomposition of punicic acid, lowers the generation of harmful substances, does not need the high-temperature refinement processes of decolorization, deacidification, deodorization and the like, and is convenient for industrial production.

Description

technical field [0001] The invention relates to a method for preparing edible oil, in particular to a method for preparing pomegranate seed oil by pressing. Background technique [0002] Pomegranate seed oil is a new type of oil that is widely used in medicine and light industry. The main fatty acid in pomegranate seed oil is punicic acid, the structure is cis-9, trans-11, cis-13-octadecatriene, and it is a polyunsaturated fatty acid with a conjugated structure. The content in pomegranate seed oil can reach 70 %above. [0003] Pomegranate seed oil contains a large amount of conjugated triene fatty acids (namely: punicic acid), which is very active in nature. It is a very unique and effective antioxidant that can resist inflammation and oxygen free radical damage. It has the functions of delaying aging and preventing atherosclerosis Hardening, anti-cancer, hypoglycemic and anti-diarrheal effects. With people's continuous understanding of pomegranate seed oil, Europe and th...
