Abstract
The name of the invention is: a method for extracting oil from food material with solvent is provided. The invention relates to a processing method for extracting oil from food materials by adopting a solvent and removing fat from the food materials. The core technology of the invention is as follows: extracting oil and fat in the food material by adopting a solvent. The process comprises soaking food materials such as meat, nuts and fried food materials in a solvent, dissolving oil and fat in the solvent at a proper temperature and pressure, separating the oil-containing solvent from the food materials, removing the solvent from the food materials to obtain oil-removed food materials, separating the oil and fat in the oil-containing solvent from the solvent, and allowing the oil and fat to be eaten, wherein the solvent is recycled.
Description
One, the technical field
The invention relates to a processing method for extracting oil from food materials by adopting a solvent and removing fat from the food materials.
Second, background Art
The food material is raw material required for preparing food.
In life, food materials such as meat, nuts and fried food materials contain high fat, and the fat exists in the following modes: the free state is that the food material is on the surface and in the gap in a free mode; or in a bound state in the cell structure of the food material.
A large amount of grease contained in the food materials can enter various foods finally, and a large amount of grease can be ingested when people eat the foods, so that the health of the people is not facilitated; meanwhile, due to the existence of a large amount of grease in food, greasy taste of the food is easily caused.
Therefore, the reduction of fat in food is a problem to be solved.
Third, the invention
The core technology of the invention is as follows: extracting oil and fat in the food material by adopting a solvent.
The process comprises soaking food materials such as meat, nuts and fried food materials in a solvent, dissolving oil and fat in the solvent at a proper temperature and pressure, separating the oil-containing solvent from the food materials, removing the solvent from the food materials to obtain oil-removed food materials, separating the oil and fat in the oil-containing solvent from the solvent, and allowing the oil and fat to be eaten, wherein the solvent is recycled.
The food material in the invention refers to natural oil-containing meat, oil-containing nuts or semi-finished food material after frying.
The solvent in the present invention means an organic solvent such as propane, butane, hexane, etc. or a supercritical gas such as carbon dioxide.
The temperature of the process is-20 to 150 ℃, and the pressure is normal pressure to 18 Mpa.
Description of the drawings
The process flow chart is shown in figure 1
The process equipment mainly comprises a grease extractor, a grease separator and the like.
Fifth, detailed description of the invention
The operation process is as follows:
1. putting the food material into a grease extractor;
2. adding a solvent into a grease extractor, and extracting grease in the food materials at a proper temperature and pressure;
3. discharging the fat-containing solvent to a fat separator;
4. separating residual solvent in the oil extractor food material, and taking out the oil-removed food material;
5. separating the grease and the solvent in a grease separator to respectively obtain the grease and the solvent;
6. and (5) recycling the solvent.
Claims (4)
1. A method for extracting oil from food materials by adopting a solvent is characterized in that the oil in the food materials is extracted by adopting the solvent, the food materials are processed, and the oil in the food materials is removed.
2. The method of claim 1, wherein the oil is extracted from a food material selected from the group consisting of natural oil-containing meat, oil-containing nuts, and fried food.
3. The method for extracting oil from food material with solvent according to claim 1, wherein the solvent is organic solvent such as propane, butane, hexane, etc. or supercritical gas such as carbon dioxide.
4. The method for extracting the oil and fat from the food materials by adopting the solvent according to the claim 1, wherein the temperature of the process is-20 ℃ to 150 ℃, and the pressure is normal pressure to 18 Mpa.
