Problems solved by technology

However, this process has certain deficiencies in the production process. The last step is winterization dewaxing. It will cause the moisture in the air around the oil to condense into water and enter the oil when it is condensed, so that the moisture in the oil after winterization and filtration will increase; since the winterization and dewaxing process is the last process of production, it will inevitably cause defects in product quality. To ensure the quality of the final product, a comprehensive temperature insulation device and corresponding refrigeration equipment must be installed in a large space around the winterization filtration process, which will directly increase the production cost

Embodiment 1

[0013] Embodiment 1: The production method of this wheat germ oil adopts following processing steps.

[0014] 1. Degumming and deacidification process: 1000kg of wheat germ crude oil is heated to 40°C, and food-grade citric acid with an oil weight of 1.5% is added to the oil, stirred rapidly for 15 minutes, and then sodium hydroxide solution is added for alkali refining (deacidification) , the addition of sodium hydroxide solution is the same as the conventional deacidification addition;

[0015] 2. Water washing process: After alkali refining, raise the oil temperature to 85°C, add 95°C hot water according to the proportion of 9% of the oil weight, let it rest for 40 minutes, drain water, and wash twice;

[0016] 3. Decolorization process: After washing with water, heat the oil to 110°C in a decolorization pot. After removing most of the water, the oil temperature quickly drops to 90°C. Add activated clay with an oil weight of 3% and activated carbon with an oil weight of 0.3...

[0019] Embodiment 2: The production method of this wheat germ oil adopts following processing steps.

[0020] 1. Degumming and deacidification process: 1000kg of wheat germ crude oil is heated to 40°C, and food-grade citric acid with an oil weight of 1.5% is added to the oil, stirred rapidly for 15 minutes, and then sodium hydroxide solution is added for alkali refining;

[0021] 2. Water washing process: After alkali refining, raise the oil temperature to 85°C, add 95°C hot water according to the proportion of 9% of the oil weight, let it rest for 40 minutes, drain water, and wash twice;

[0022] 3. Decolorization process: After washing with water, heat the oil to 110°C in a decolorization pot. After removing most of the water, the oil temperature drops to 90°C. Add activated clay with an oil weight of 4% and activated carbon with an oil weight of 0.2% to decolorize for 20 minutes Cool down to 70°C and filter;

[0023] 4. Winterization and dewaxing process: After decolorizat...

Embodiment 3

[0025] Embodiment 3: The production method of this wheat germ oil adopts following processing steps.

[0026] 1.

Abstract

The invention discloses a method for producing wheat germ oil. The method comprises the following steps: degelatinizing, deacidifying, rinsing, decoloring, winterizing, dewaxing and deodorizing wheat germ crude oil, so as to obtain the finished wheat germ oil product. As the winterizing and the dewaxing processes are carried out before the deodorizing process, water entering into the wheat germ crude oil during the winterizing and the dewaxing processes can be desorbed with odor materials in the deodorizing process under the high-temperature high-vacuum condition, which effectively reduces the water content of the wheat germ oil. As no production equipment and no chemical assistant are additionally adopted, the process is simple, the operation is convenient, and the water content of the finished wheat germ oil product fully meets the moisture content index required in the national standard, and the product quality of the wheat germ oil is ensured.

Description

technical field [0001] The invention relates to a production method of edible oil, in particular to a production method of wheat germ oil. Background technique [0002] At present, the edible oils used in people's daily life in our country are mainly soybean oil, cottonseed oil, rapeseed oil and other bulk oils and fats. With the improvement of living standards, people's demand for small varieties of oils and fats is increasing day by day, but the processing of small varieties of oils must adopt intermittent production methods due to the lack of raw materials and special nutrients. At present, the intermittent production and processing of wheat germ oil still adopts the traditional production process, namely extraction, degumming and deacidification, washing, decolorization, deodorization, and winterization and dewaxing processes. However, this process has certain deficiencies in the production process. The last step is winterization dewaxing. It will cause the moisture in...
