Embodiment 1

[0014] Embodiment 1, a kind of pressing method of black pearl sunflower oil, comprises the following steps:

[0015] Keep the black pearl sunflower seeds under the microwave power of 32W / g and the pressure of 0.15MPa for 20 minutes, and then drop it to a vacuum state for 12 minutes;

[0016] Knead and shell the black pearl sunflower seeds;

[0017] The shelled black pearl sunflower seeds were pressed repeatedly for 30 minutes at a temperature of 40°C and a pressure of 60 MPa to obtain crude oil and pressing residue;

[0018] Crush the crushed residue to 200 mesh, add water at a volume ratio of 1:3, adjust the pH to 5, add papain to enzymolyze at 50°C for 30 minutes, then inactivate the enzyme, pass through a 60-mesh sieve, and retain the enzymatic residue;

[0019] Dry the enzymolysis residue at 60-80°C until the water content is less than 10%;

Abstract

The invention relates to the technical field of edible oil processing, in particular to a pressing method of black pearl sunflower seed oil. Black pearl sunflower seeds are kept for 20-22 min under the pressure of 0.15-0.18 MPa in the microwave power of 32-35 W/g, the pressure is reduced immediately until the black pearl sunflower seeds are in the vacuum state, the black pearl sunflower seeds are kept for 12-15 min in the vacuum state, rolled and shelled, the shelled black pearl sunflower seeds are repeatedly pressed for 30-40 min, crude oil and pressed residues are obtained, the pressed residues are crushed, water is added, the volume ratio of water to the pressed residues is 1:3, the PH (potential of hydrogen) is adjusted to 5, papain is added for enzymolysis, enzymolysis residues are reserved and dried until the water content is lower than 10%, the enzymolysis residues are fed to a steam generator and distilled at the steam temperature of 100-120 DEG C under the pressure of 0.022-0.025 MPa until no clear oil droplets flow out of effluent, distillation is stopped, and distilled oil is obtained; the crude oil and the distilled oil liquid are mixed and introduced into the steam generator to be distilled at the steam temperature of 130-150 DEG C under the pressure of 0.035-0.038 MPa until no clear oil droplets flow out of effluent, and distillation is stopped.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a pressing method of black pearl sunflower oil. Background technique [0002] Sunflower seeds are the fruits of sunflowers. Their kernels contain 30%-45% fat, up to 60%. Sunflower oil is golden in color, clear and transparent, and has a delicate smell. It is an important edible oil. It contains a large amount of linoleic acid and other essential unsaturated fatty acids, which can promote the regeneration and growth of human cells, protect skin health, and reduce the accumulation of cholesterol in the blood. It is a high-grade nutritional oil. Its color is golden and clear. Transparent, with aromatic odor. The consumption of sunflower oil in the world ranks fourth after palm oil, soybean oil and rapeseed oil among all vegetable oils. The global sunflower oil production is stable between 10 million and 12 million tons. It is one of the important edible oil varieties...
