Problems solved by technology

However, the pomegranate oil produced by the extraction method cannot be completely removed due to the large amount of organic solvent residues, which destroys the natural, environmentally friendly and safe characteristics of pomegranate seed oil. It is not accepted by high-end products and can only be used for low-end products; at the same time, The extraction method is a selective extraction, and cannot extract all the active ingredients in the pomegranate seeds as a whole, thus causing the loss of some effective active substances

Embodiment 1

[0019] Preparation process:

[0020] 1. Process the dried pomegranate seeds with a rubbing machine to remove pomace residues and dust attached to the shell;

[0021] 2. Grind 10kg of clean pomegranate seeds on a pulverizer, the mesh of the pulverizer is 30 mesh, and the motor speed is 1500 rpm; the cavity of the pulverizer is fed with cooling water and inserted into a temperature feedback device. , the feedback device sends a signal, the pulverizer stops, and starts to run after the temperature drops;

[0022] 3. Use a 40-mesh sieve to screen on a vibrating sieve machine. The seed kernels are soft and can pass through the sieve after being crushed, while the seed shells are blocked by the sieve.

[0023] 4. Put the kernels into the mixer, add pure water to make the moisture content of the kernels 15%, and stir and mix for 50 minutes;

[0024] 5. Use a tablet machine to compress the stirred kernels into round grains with a diameter of 4-6 mm.

[0025] 6. Put the kernels into...

Abstract

The invention relates to a method for preparing pomegranate seed oil, which can extract various nutritional components and protect the nutritional components from being destroyed. The method comprises the following steps: pomegranate seeds are pulverized on a pulverizer, the pulverizer stops if the temperature of the pomegranate seeds in the pulverizer is higher than 50 DEG C, and the pulverizer continues to work after the temperature drops; the pulverized pomegranate seeds is screened with a screen stencil, so pulverized pomegranate seed kernels pass through the screen stencil, and seed shells are blocked by the screen stencil; water is added into the seed kernels to make the water ratio of the seed kernels reaches 10 to 15 percent; the seed kernels are pressed into round grainy seed kernels by a performing machine, and the diameter of the round grainy seed kernels is 3 to 6 millimeters; the seed kernels are put into a vacuum adjusting box, and the water ratio of the seed kernels is reduced to 6 to 8 percent by adjusting the vacuum degree and the temperature; the seed kernels are put into a screw oil mill to obtain crude oil through extrusion; and the oil mill stops if the temperature of the crude oil rises to 50 DEG C, and the oil mill continues to work when the temperature drops.

Description

technical field [0001] The invention relates to a method for preparing pomegranate seed oil, in particular to a method for preparing pomegranate seed oil by cold-pressing pomegranate seeds (the whole process temperature does not exceed 48.8°C). Background technique [0002] Pomegranate seed oil is rich in polyunsaturated fatty acids, especially the content of conjugated linoleic acid (punicic acid) can reach more than 70%-80%. Therefore, pomegranate seed oil is recognized as having a strong antioxidant capacity and is a kind of Excellent raw material for natural health products, cosmetics, skin care products. In addition to polyunsaturated fatty acids, pomegranate seed oil also contains phytosterols and other substances, which play a synergistic protective effect on human health and skin maintenance. [0003] In recent years, with the gradual improvement of people's awareness of the value of pomegranate seed oil, some methods for preparing pomegranate seed oil have been app...
