Maize germ oil production process with six fresh-keeping steps

Abstract

The invention belongs to the technical field of oil processing, and in particular relates to a six-stage fresh-keeping production process of corn germ oil. The technical scheme of the present invention includes the following process steps: raw material preservation, screening preservation, pressing preservation, refining preservation, nitrogen filling preservation and airtight preservation. From the selection of jade raw materials to the packaging of finished oil, the whole process of corn germ oil preparation is carried out. While removing impurities and harmful substances in it to the greatest extent, it ensures the freshness of corn germ oil, thereby retaining the beneficial ingredients in it. .

Description

technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to a six-stage fresh-keeping production process of corn germ oil. Background technique [0002] In the molecular structure of oil, the molecular weight of fatty acid accounts for about 95% of the molecular weight of the whole triglyceride. The composition of fatty acid has an important influence on the nutritional function of oil, and the type and proportion of fatty acid are closely related to human cardiovascular and cerebrovascular health and nutritional status. relevant. [0003] The country's "2020 Medium and Long-term Development Plan---New Technology of Vegetable Oil and Oil Processing" gave a high evaluation to corn oil. Corn oil contains 86% unsaturated fatty acids, 56% of which are linoleic acid, and the human body absorption rate It can reach more than 97%; it is rich in vitamin E, which plays an important role in human cell division and anti-aging. ...

AI Technical Summary

Problems solved by technology

It often happens that corn that is more than 2 years old enters the starch factory for separation and germ extraction. During the long-term storage of old corn, mildew and moths often appear. Remove, seriously affect product quality, urgently need to find a way to solve this problem

[0007] 2. Germ raw materials have high impurity content

[0008] 3. The pressing temperature is too high, the crude oil is stored at high temperature in the oil tank, the oil will undergo peroxidation and deterioration, the difficulty of refining will increase, the addition of auxiliary materials will increase, and the process indicators will not be easy to control

[0009] 4. The refining process is managed extensively, and oils and fats produce trans fatty acids under high temperature and high pressure, which is harmful to the human body

[0010] 5. Corn germ oil is rich in oleic acid and linoleic acid, which is easy to change color

[0011] 6. Poor airtightness

[0012] The low degree of automation in crude oil plants has become a technical barrier to the industry, and the randomness of workers' operations has become an insurmountable phenomenon

The main manifestations are: uneven germ ingredients, for example, different manufacturers have different germ moisture and impurities, which directly affect the thickness and powder degree of the germ slices, and there is a lack of online moisture monitoring equipment
