Problems solved by technology

But the extraction of wheat germ oil is more difficult. About 1000 kg of wheat can extract 15 kg of germ, and only 4--6% of wheat germ oil can be extracted from 100 kg of wheat germ, which restricts the market development of wheat germ oil
[0005] The traditional compound oil production is to press the oil crops separately first, and then mix the finished oils obtained by pressing separately to obtain the final compound oil. May cause structural changes in some functional components, which may have adverse effects on nutritional quality

Embodiment 1

[0024] The production method of described cold-pressed peanut corn wheat germ compound oil comprises the following steps:

[0025] (1) Wheat bran pretreatment: first add wheat bran to a high-speed rotary blade grinder, pulverize for 1 to 3 minutes, and then steam treat the pulverized wheat bran under normal pressure for 20 to 30 minutes;

[0026] (2) Corn germ pretreatment: first put the corn germ into a low-temperature dryer for drying, the temperature of the hot air is 80-100°C, and the drying time is 20-30 minutes, and then it is cooled to make the discharge temperature reach the normal room temperature; then The cooled corn germ is then sent to the cleaning sieve for cleaning twice, the impurities are sorted out, and the germ is rolled; finally, it is steamed and fried;

[0027] (3) Pretreatment of peanut kernels: first, put the peanut kernels into a low-temperature dryer for drying. The temperature of the hot air is 80-100°C, and the drying time is 20-30 minutes. Then, it...

Abstract

The invention belongs to the technical field of producing and processing cold pressing edible oil and particularly relates to a production method for cold pressing compound oil of peanut, corn and wheat germs. The production method for the cold pressing compound oil of the peanut, corn and wheat germs comprises the following steps: (1) preprocessing of wheat bran, (2) preprocessing of corn germs, (3) preprocessing of peanut kernels, (4) modifying, (5) cold pressing, and (6) filtering, wherein the specific steps of (4) modifying are as follows: uniformly mixing the preprocessed wheat bran, corn germs and peanut kernels with the weight ratio of (1-3):(2-6):(7-23) to prepare a raw material, adding water with the weight of 2%-4% of the weight of the raw material and water temperature of 60-80 DEG C to the raw material and keeping 40-60 minutes for water absorption and softening. The compound edible oil abundant in unsaturated fatty acid and vitamin E is produced with the adoption of the method by utilizing the peanut kernels, corn germs and wheat bran as the raw materials and adopting the cold pressing process.

Description

technical field [0001] The invention belongs to the technical field of cold-pressed edible oil production and processing, and in particular relates to a production method of cold-pressed peanut-corn-wheat-germ compound oil. Background technique [0002] Since the advent of cold-pressing technology, it has developed rapidly. Due to the light color of cold-pressed oil, the extremely small phospholipid content, and the nutritional factors have not been destroyed by high temperature, the crude oil does not need complicated refining and can be eaten only by physical filtration. "Green environmental nutrition oil". Cold-pressed peanut oil contains more than 80% unsaturated fatty acids, and the composition of fatty acids is reasonable, which is easy for human body to digest and absorb. Cold-pressed peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste, and is widely welcomed in the market. However, due to the low temperature of the cold ...
