Embodiment 1

[0023] Example 1, a cold pressing process for non-genetically modified soybean oil was achieved by adopting the following process steps:

[0024] 1. Selection of raw materials: select 1000kg of non-GMO soybeans that are well preserved, not contaminated by molds, high in protein content, above 34.0%, the higher the better, and the full-grained soybeans;

[0025] 2. Selection of raw materials: 1) First pass through a vibrating screen to remove impurities, ash and soil with a larger diameter than bean grains; 2) Then pass through a wind screen to remove impurities with lighter weight such as grass clippings; 3) Impurity removal by specific gravity machine: send the pre-selected soybean raw materials into the specific gravity impurity removal machine to remove impurities that are similar in volume to soybean particles but different in density, such as sand, etc.; 4) Picking and sorting with the machine: removing impurities The soybean raw materials are sent to the conveyor. After the c...

Embodiment 2

[0033] Example 2 is the same as Example 1. The difference is that in step 4, when the crude oil yield reaches 12%, the pressurization is stopped. At this time, the soybean cake residual oil is generally 6.0%. This process produces about 110kg of crude soybean oil. Soybean meal is about 890kg; the irradiation dose in step 7 is 400 J / m 2 , The irradiation time is 5 seconds; in step 8, heat the processed soybean oil obtained in the previous step to 100°C for standby; turn on the heating device of the vacuum tank to maintain the temperature in the tank at 100°C; start the vacuum pump to make the absolute The pressure drops below 400Pa; open the feed valve, slowly suck in the heated soybean oil, so that the hot soybean oil that enters is instantly bumped, and the peculiar smell is removed; the feed volume is controlled, and the liquid temperature in the vacuum tank is maintained at 100°C, absolute pressure Not more than 400Pa; after the feeding is completed, keep the operating condit...

Embodiment 3

[0034] Example 3 is the same as Example 1, except that in step 4, when the crude oil yield reaches 10%, the pressurization is stopped. At this time, the soybean cake residual oil is generally 7.5%. This process produces approximately 96kg of crude soybean oil. Soybean meal is about 900kg; the irradiation dose in step 7 is 200 J / m 2 , The irradiation time is 15 seconds; in step 8, heat the processed soybean oil obtained in the previous step to 90°C for standby; turn on the heating device of the vacuum tank to maintain the temperature in the tank at 90°C; start the vacuum pump to make the absolute The pressure drops below 400Pa; open the feed valve and slowly suck in the heated soybean oil, so that the hot soybean oil that enters will boil instantaneously to remove the peculiar smell; control the feed volume and keep the liquid temperature in the vacuum tank at 90℃, absolute pressure No more than 400Pa; after the feeding is completed, keep the operating conditions unchanged and co...

Abstract

The invention discloses a non-transgenic soybean oil cold pressing preparation process which is characterized by including the steps of raw material selection and polishing and dehulling, pressing moisture adjustment, pressing and residual oil control, crude oil filtering, removal of lipoxygenase by hyperfiltration and removal of beany flavor by bumping in vacuum at the low temperature. Non-transgenic soybeans serving as raw materials eliminates potential hazard possibly caused by transgenic raw materials, and using the physical cold pressing technology enables a product to be free from organic solvent residues, eliminates contamination of aflatoxin on the raw materials and biological factors resulting in deterioration during soybean oil storage, effectively removes the beany flavor and other peculiar smell in soybean oil and is rich in natural antioxidants such as VE (vitamin E) and the like so that extra antioxidants do not need to be added during oil storage.

Description

Technical field: [0001] The invention relates to the technical field of soybean oil processing, in particular to a cold-pressing preparation process of non-genetically modified soybean oil. Background technique: [0002] Soybean oil is an indispensable edible oil in people’s daily life. It is mainly used for cooking, frying, frying and frying food. The consumption is very large. The safety and nutritional health value of soybean oil are becoming more and more hotspots. . [0003] At present, soybean oil products mainly have the following safety hazards: [0004] 1. Unsafe factors caused by raw material problems. At present, most soybean oil production uses genetically modified soybeans, which causes potential food safety hazards in the products; [0005] 2. Unsafe factors caused by the solvent extraction process. At present, the production of soybean oil generally uses a solvent extraction process with a high degree of mechanization and a high oil yield. The soybean oil produced by t...
