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
[0004] 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

[0021] The production method of cold-pressed peanut and wheat germ compound oil comprises the following steps:

[0022] (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;

[0023] (2) Pretreatment of peanut kernels: firstly, 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 is cooled to make the discharge temperature reach the normal room temperature; then The cooled peanut kernels are immediately sent to the undressing machine to remove the red coat, and then the kernel skin is separated, and the unreddened peanut kernels and the discolored peanut kernels are sorted out; finally, the selected ones that have taken off the red coat are The peanut kernels are added to the splitter for crushing, and the particle size is 4...

Abstract

The invention belongs to the technical field of production and processing of cold pressing edible oil, and particularly relates to a production method of cold pressing peanut and wheat germ compound oil. The production method of the cold pressing peanut and wheat germ compound oil comprises the following steps: (1) preprocessing of wheat bran, (2) preprocessing of peanut kernels, (3) modifying, (4) cold pressing and (5) filtering, wherein the specific steps of (3) modifying are as follows: uniformly mixing the preprocessed wheat bran and the peanut kernels with the weight ratio of (1-2):(4-12) to prepare a raw material, adding water, with the weight of 2%-4% of the weight of the raw material and the water temperature of 60-80 DEG C, to the raw material, and keeping 40-60 minutes for waterabsorption and softening. In the method, the wheat bran added to the peanut kernels can increase the oil yield of the peanut kernels; in addition, the peanut and wheat germ compound oil prepared by the method is rich in vitamin E, and integrates the nutritional functions of peanut oil and wheat germ oil, and the nutritional value is increased.

Description

technical field [0001] The invention belongs to the technical field of production and processing of cold-pressed edible oil, and in particular relates to a production method of cold-pressed peanut and 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 col...
