Problems solved by technology

Ordinary cold pressing only performs flaking on the oil embryos without special treatment, resulting in incomplete damage to the cell wall of the oil seeds, resulting in an excessively high oil residue rate, and the cold pressing adopts a constant pressure leaching method, and the extraction efficiency is not high. The seed shell is hard, the cellulose content is high, and the repeated friction with the press chamber makes the processing temperature difficult to control, the oil yield is low, the anisidine value is high, and the punicic acid isomerization phenomenon is serious, which greatly affects the nutritional value of the product
In addition, traditional oil seed coats, residues, etc. will absorb and consume part of the oil, further reducing the oil yield

Embodiment 1

[0028] A kind of preparation method of high-quality pomegranate seed oil, comprises the steps:

[0029] (1) Removal of impurities: take fresh pomegranate seeds, remove impurities, moldy and deteriorated pomegranate seeds for later use, then pick out large particles of impurities, and then use a sieve to screen out the small solid particles of pomegranate seeds, and remove impurities for use ;

[0030] (2) Soaking: Soak pomegranate seeds in a 3% citric acid solution 4 times its total mass for 2 hours, take it out and put it in 3% baking soda 4 times its total mass Soak in the solution for 2 hours, and finally take it out and rinse it with clean water for later use;

[0031] (3) Warm cooking: Put the washed pomegranate seeds into water 3.5 times the total mass, heat to keep the water temperature at 42-44°C, boil for 15-20 minutes, take it out for later use, and keep stirring during the boiling;

[0032] (4) Pretreatment: Put the boiled pomegranate seeds into an airtight contai...

Abstract

The invention discloses a preparation method of high-quality pomegranate seed oil. The preparation method comprises the following steps: (1) removing impurities; (2) soaking; (3) boiling with a warm fire; (4) carrying out pretreatment; (5) peeling; (6) screening; (7) carrying out cryogenic pulverization; (8) carrying out enzymolysis; (9) drying; (10) squeezing; and (11) purifying. The preparation method disclosed by the invention has the advantages that technology matching is scientific and reasonable, the whole energy consumption is low, cost is low, no chemical substance is introduced, safety of the pomegranate seed oil is guaranteed, content of harmful substances in oil is also reduced, and appearance quality and taste of the oil are improved; and finally oil extraction rate of pomegranate seeds is more than 20%, and good economic benefit and popularization value are obtained.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of high-quality pomegranate seed oil. 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 see...
