Problems solved by technology

The protein and phospholipid film on the outer layer of oil droplets can be destroyed by high-temperature steaming and frying to improve the oil yield, while the extraction process will cause solvent residues in the finished oil
The steaming processing temperature is generally 100°C-140°C, the frying processing temperature is generally 200°C-300°C, and the cavity temperature of the screw press is generally 200°C-250°C. The above processing process will generate carcinogen benzene. And (a) pyrene, simultaneous leaching and steaming processes will cause a large amount of free fatty acids to exist in the oil, which will increase the acid value, resulting in a large amount of peroxides in the oil

Embodiment 1

[0038] Use the sorting machine to classify the purchased camellia seeds, and separate them into: fresh fruit, semi-dried fruit, and dried fruit, and only use fresh camellia seeds for oil extraction.

[0039] The size of fresh camellia oleifera seeds was screened by mesh sieve and divided into two groups.

[0040] The camellia seeds are grouped and dried, spread out to make them evenly heated, and dried until the moisture content of the camellia seeds is below 10%.

[0041] Camellia oleifera seeds are sprayed with 3% salt water, then frozen at -30°C for 45 minutes for crushing, and the crushed camellia oleifera seeds are pressed for the first time to make oil. The pressing conditions are as follows: low temperature press, pressing temperature 45°C, rotating speed 40r / min, pressing chamber pressure 3.5Mpa, to obtain crude oil.

[0042] Pour the crude oil into the pot and heat it to 70°C, then add a sodium chloride solution with a temperature of 80°C and a concentration of 40% b...

Embodiment 2

[0054] Use the sorting machine to classify the purchased camellia seeds, and separate them into: fresh fruit, semi-dried fruit, and dried fruit, and only use fresh camellia seeds for oil extraction.

[0055] The size of fresh camellia oleifera seeds was screened by mesh sieve and divided into two groups.

[0056] The camellia seeds are grouped and dried, spread out to make them evenly heated, and dried until the moisture content of the camellia seeds is below 10%.

[0057] Camellia oleifera seeds are sprayed with 6% salt water, then frozen at -30°C for 60 minutes for crushing, and the crushed camellia oleifera seeds are pressed for the first time to make oil. The pressing conditions are as follows: low temperature press, pressing temperature 55°C, rotating speed 45r / min, pressing chamber pressure 3.5Mpa, to obtain crude oil.

[0058] Pour the crude oil into the pot and heat it to 75°C, then add a sodium chloride solution with a temperature of 90°C and a mass percentage concen...

Embodiment 3

[0070] Use the sorting machine to classify the purchased camellia seeds, and separate them into: fresh fruit, semi-dried fruit, and dried fruit, and only use fresh camellia seeds for oil extraction.

[0071] The size of fresh camellia oleifera seeds was screened by mesh sieve and divided into two groups.

[0072] The camellia seeds are grouped and dried, spread out to make them evenly heated, and dried until the moisture content of the camellia seeds is below 10%.

[0073] Camellia oleifera seeds are sprayed with 5% salt water, then frozen at -30°C for 50 minutes for crushing, and the crushed camellia oleifera seeds are pressed for the first time to make oil. The pressing conditions are as follows: low temperature press, pressing temperature 50°C, rotating speed 43r / min, pressing chamber pressure 3.5Mpa, to obtain crude oil.

[0074] Pour the crude oil into the pot and heat it to 72°C, then add a sodium chloride solution with a temperature of 85°C and a mass percentage concen...

Abstract

The invention discloses a preparation method of tea oil. The preparation method has the beneficial effects that the operation of a cold pressing process is simple, the oil extraction rate of tea seeds is guaranteed, and the quality of the tea oil is not influenced; preparations required to be added in a refining process are common substances in the daily life and are low in cost, silicone oil and fatty acid monoglyceride succinate or citric acid monoglyceride succinate are added, so that a grease composition for heating and cooking in oil content remained in cooking objects can be efficiently reduced; by virtue of a method for treating tea oil through ultrahigh magnetism and ultrahigh pressure techniques, polyunsaturated fatty acid in the tea oil can be converted into monounsaturated fatty acid, the color is relatively deep, the fragrance is relatively strong, and the guarantee period is relatively long; natural plant polysaccharide and a biological enzyme regent are utilized as raw materials for removing a trace plasticizer in the tea oil, and organic solvents are not used, so that the residual solvent is avoided, and the safety of the tea oil is greatly improved.

Description

technical field [0001] The invention belongs to the field of edible oil production, and in particular relates to a preparation method of camellia oil. Background technique [0002] Vegetable edible oil is a compound composed of unsaturated fatty acid and glycerol. It is widely distributed in nature and is obtained from the fruit, seed and germ of plants. Such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc. The main components of vegetable oil are esters of straight-chain higher fatty acids and glycerol. In addition to palmitic acid, stearic acid and oleic acid, fatty acids also contain a variety of unsaturated acids, such as erucic acid, oleic acid, and ricinoleic acid. Vegetable oil mainly contains vitamin E, K, calcium, iron, phosphorus, potassium and other minerals, fatty acids, etc. Vegetable oil is one of the indispensable and important foods in people's daily life. [0003] Camellia oil is rich in nutrients and contains fatty acids (93% unsat...
