Problems solved by technology

The existing corn germ oil production process is to deodorize the oil at a high temperature of 260°C to 280°C for 2 to 6 hours, and to dewax it at a temperature of 15°C to 30°C. Formula acid oil is not conducive to human health; steam distillation makes oil easy to hydrolyze, so that polyunsaturated acid oil has polymer formation; it is easy to cause loss and damage of trace elements and their nutritional components, reducing the nutritional value of oil; steam A large amount of energy is wasted, and the production cost is increased
Due to the long process time, the deodorization temperature is too high, the deodorization effect is not ideal, the high wax content of the product makes the mouth feel bad when eaten, the taste is not good, and the taste is not good, which affects the consumption of corn germ oil.

Embodiment 1

[0025] Under the condition of sealing and air-free, take 100kg of corn germ crude oil and heat it to 80°C, add 0.1kg of edible phosphoric acid with a concentration of 65%, mix well and react with the colloid in the oil, and then add 8kg of alkali (NaOH) for neutralization Free fatty acids and excess phosphoric acid form soapstock at last. The soapstock is separated from the oil by a centrifuge, and the liquid is washed with hot water at 80°C to 95°C to remove residual soapstock and lye in the oil. After dehydration and drying Add 1 kg of activated clay, heat at 105-130°C for 15-25 minutes, absorb the pigment in the oil, filter and decolorize; after the oil is decolorized, at 85°C-90°C, it enters the first frozen crystal growth tank through the cooler, and in the tank Stir in the crystal growth tank, the cooling rate in the crystal growth tank is 6-10°C / h, the stirring speed is 10-13 rpm, when it cools to 25°C-30°C, it is pumped into the second crystal growth tank, and then cool...

Embodiment 2

[0027] In a vacuum state, heat 100kg of corn germ crude oil to 90°C, add 0.15kg of 80% edible phosphoric acid, mix well and react with the colloid in the oil, then add 10kg of alkali (NaOH) for neutralization after the reaction , centrifuge and separate soapstock and oil, take the separated liquid and wash it with hot water at 80°C to 95°C to remove residual soapstock and lye in the oil, add 1kg activated clay after dehydration and drying, heat at 105 to 130°C, 15 to 25 Minutes, absorb the pigment in the oil, filter and decolorize; after the oil is decolorized, at 85°C-90°C, it enters the first frozen crystal growth tank through the cooler, and stirs in the tank, and the cooling rate in the crystal growth tank is 6-10°C / h , with a stirring speed of 13 rev / min, pumped into the second crystal growth tank when cooled to 25°C-30°C, and then cooled to 13°C-15°C, when the stirring speed slowed down to 5°C-8°C, the final temperature of dewaxing was 6 ℃, the small particles of wax are...

Embodiment 3

[0029] Get 50 kg of corn germ oil, 10 kg of rice bran oil, 5 kg of safflower oil, and 5 kg of pine nut oil obtained in Example 1 or Example 2 and put them into a mixing tank respectively, heat at 80° C. and stir evenly, remove impurities through high-pressure filtration, and prepare Get corn germ table oil.

Abstract

The present invention provides a production process of maize germ oil, at the same time discloses a table oil made up by its product. It is characterized by that it makes the maize germ raw material oil undergo the processes of degumming, deacidification, water-washing, decolouring, dewaxing and deodorization so as to obtain the refined edible finished oil. According to the physicochemical properties and nutrient components of other plant oil said maize germ oil and other plant oil can be made into the table oil using maize germ oil as main component. The described plant oil can be one of rice oil, carthamus oil, walnut oil, scabish oil, pine seed oil, sesame oil, peanut oil, wheat-germ oil, sunflower oil and soybean oil or their mixture.

Description

Technical field: [0001] The invention provides a production process of corn germ oil, discloses a table oil made from the corn germ oil, and relates to the technical field of vegetable oil processing and preparation methods. Background technique: [0002] Because corn germ oil is rich in unsaturated fatty acids, vitamins A, D, E and other trace elements, it plays a certain health care function on human health and taste adjustment and human blood, soft tissues and organs, so it is an ideal table. Oil. The existing corn germ oil production process is to deodorize the oil at a high temperature of 260°C to 280°C for 2 to 6 hours, and to dewax it at a temperature of 15°C to 30°C. Formula acid oil is not conducive to human health; steam distillation makes oil easy to hydrolyze, so that polyunsaturated acid oil has polymer formation; it is easy to cause loss and damage of trace elements and their nutritional components, reducing the nutritional value of oil; steam The consumption...
