Embodiment 1

[0023] (1) Weigh 20g of walnut kernels (with an oil content of 60%~70%), dry them at about 40°C, and grind them into a slurry with a sesame oil refiner;

[0024] (2) Add 1.6g of sodium chloride, 0.16g of α-amylase (activity ≥ 3700 activity units / g), 2.0g of cellulase (activity 10000u / g) into the slurry, then add 100mL of distilled water and stir well mixed;

[0025] (3) The mixed system was stirred and enzymolyzed at 50°C for 2 hours to obtain the enzymolyzed product;

[0026] (4) Centrifuge the enzymatic hydrolysis product at a temperature of 15°C and a speed of 6000r / min for 15 minutes; collect the centrifuged product in the upper layer, which is pure natural walnut seed oil, and the extraction rate is 78.93%.

Embodiment 2

[0028] (1) Weigh 20g of walnut kernels (with an oil content of 60%~70%), dry them at about 50°C, and grind them into a slurry with a sesame oil refiner;

[0029] (2) Add 2.0g sodium chloride, 0.2g α-amylase (activity ≥ 3700 activity units / g), 2.4g cellulase (activity 10000u / g) into the slurry, then add 120mL distilled water and stir well mixed;

[0030] (3) The mixed system was stirred and enzymolyzed at 55°C for 3 hours to obtain the enzymolyzed product;

[0031] (4) Centrifuge the enzymatic hydrolysis product at a temperature of 20°C and a rotational speed of 7000r / min for 20 minutes; collect the centrifuged product in the upper layer, which is pure natural walnut seed oil, and the extraction rate is 80.35%.

Embodiment 3

[0033] (1) Weigh 20g of walnut kernels (with an oil content of 60%~70%), dry them at about 60°C, and grind them into a slurry with a sesame oil refiner;

[0034] (2) Add 2.4g sodium chloride, 0.24g α-amylase (activity ≥ 3700 activity units / g), 2.8g cellulase (activity 10000u / g) to the slurry, then add 140 mL of distilled water, Stir to mix well;

[0035] (3) The mixed system was stirred and enzymolyzed at 60°C for 4 hours to obtain the enzymolyzed product;

[0036] (4) Centrifuge the enzymatic hydrolysis product at a temperature of 25°C and a speed of 8000r / min for 30 minutes; collect the centrifuged product in the upper layer, which is pure natural walnut seed oil, and the extraction rate is 79.06%.

Abstract

The invention provides a method for preparing walnut seed kernel oil by adopting a brine enzymatic method. The method comprises the following steps of: firstly, drying walnut seed kernel at 40-60 DEG C, grinding the dried walnut seed kernel into pulp by a pulping machine, adding sodium chloride, alpha-amylase, cellulose and distilled water into the pulp, and evenly stirring and mixing; carrying out enzymolysis for 2-4h at 50-60 DEG C by stirring to obtain an enzymoiysis product; finally, carrying out centrifugation on the enzymoiysis product to obtain a centrifugal product which is the pure natural walnut seed kernel oil. After being analyzed by a gas chromatography-mass spectrometer (GC-MS), the walnut seed kernel oil prepared by the method contains rich unsaturated fatty acid, is high in oil quality, and has rich nutritive value, thus being high-quality edible oil and having functions of medical treatment and health care; furthermore, the enzymoiysis is carried out by compounding enzyme and the sodium chloride, so that the walnut seed kernel oil is low in dosage of enzyme, low in extraction cost and high in extraction ratio (79-82%) of oil product.

Description

Technical field [0001] The present invention involves a method of preparation of walnut -breed oil, especially the method of preparation of walnuts for salt enzyme -based leatroger, which belongs to the field of vegetable oil processing technology. Background technique [0002] Juglans (Juglans) belongs to the quilt plant door Gemini Plant Plants, also known as walnutae, also known as walnuts. It is native to southeast Europe, West Asia and other regions. It is one of the ancient fruit trees with a long history and rich germplasm resources in my country.Walnut is an important nut and woody oil tree species, which has high economic value: the walnuts are as high as 50%, they are rich in nutrition and delicious, can be eaten raw, and they are also high -quality raw materials for making cakes., Capital and sticks are tied as the world's four major dried fruits.Walnuts have a good health effect at the same time. The people of our country call it "long live son" and "longevity fruit"....
