Problems solved by technology

Ordinary cold pressing only performs flaking treatment on the oil embryos without special treatment, resulting in incomplete destruction of the oil seed cell wall and high oil residue rate, and the cold pressing adopts constant pressure leaching method, and the extraction efficiency is not high. In addition, the traditional Oil seed coats and residues will absorb and consume part of the oil, further reducing the oil yield

Embodiment 1

[0028] A method for preparing grape seed oil with high oil yield, comprising the steps of:

[0029] (1) Impurity removal: After removing the large particles of impurities, use a sieve to remove the small particles of solid matter from the grape seeds, and remove the impurities from the grape seeds for later use;

[0030] (2) Soaking: soak the de-impured grape seeds in a 3% tartaric acid solution that is 4 times its total mass for 2 hours, then put it in a 3% baking soda solution that is 4 times its total mass Soak it in water for 2 hours, and finally take it out and rinse it with clean water for later use;

[0031] (3) Warm cooking: put the washed grape seeds into clear water that is 3 times the total mass, heat to keep the water temperature at 40-42°C, boil for 15-20 minutes, take it out for later use, and keep stirring during the boiling;

[0032] (4) Pretreatment: Put the boiled grape seeds into an airtight container, and cool down the grape seeds at a cooling rate of 5~6°...

Abstract

The invention discloses a high-oil yield preparation method of grape seed oil. The preparation method comprises the following steps: (1) impurity removal; (2) soaking; (3) warm boiling; (4) pretreatment; (5) peeling; (6) screening; (7) low-temperature grinding; (8) enzymolysis; (9) drying; (10) squeezing; and (11) purification. In the method disclosed by the invention, the collocation is scientific and reasonable, the overall energy consumption is low, and the cost is low; without introducing chemical substances, the safety of the grape seed oil is guaranteed, the content of harmful substances in the oil is reduced, and the condition and mouthfeel of the oil are improved; and moreover, the final oil yield of the grape seeds can be kept over 98%, thereby bringing great economic benefits and popularization values.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of grape seed oil with high oil yield. Background technique [0002] The waste (skins, seeds, stems) produced in the winemaking process accounts for about 20%-30% of the total fresh fruit, of which grape seeds account for about 7%-10% of the total weight of fresh fruit. more than 42,000 tons. The northern slope of the Tianshan Mountains in northern Xinjiang and Turpan and Hami in eastern Xinjiang are rich in wine grapes, and there are many wine companies. The Shihezi reclamation area has produced 50,000 mu of wine grapes, and 40,000 mu of wine grapes are growing. It is planned to expand the planting area to 2015. 200,000 mu. At present, except for a small part of grape seeds used as feed and fertilizer, most of them are directly discarded, which not only causes waste of resources, but also increases environmental pressure. [0003] The ...
