Embodiment 1

[0014] Embodiment 1: After being pulverized to the tomato seed 800W microwave treatment of 50 order particle size ranges 10 minutes, add the dehydrated alcohol of 10% (v / w) to make entrainer, supercritical CO 2 Extraction, extraction conditions: pressure 50MPa, extraction temperature 60°C, extraction time 2.0h, separate the obtained product, which is tomato seed oil.

Embodiment 2

[0015] Embodiment 2: After being pulverized to the tomato seed 500W microwave treatment of 100 order particle size ranges 8 minutes, add the dehydrated alcohol of 8% (v / w) to make entrainer, supercritical CO 2 Extraction, extraction conditions: pressure 40MPa, extraction temperature 50°C, extraction time 1.0h, separate the obtained product, which is tomato seed oil.

Embodiment 3

[0016] Embodiment 3: after the tomato seed 300WW microwave treatment of 30 order particle size ranges is pulverized to 5 minutes, add the dehydrated alcohol of 5% (v / w) to make entrainer, supercritical CO 2 Extraction, extraction conditions: pressure 30MPa, extraction temperature 40°C, extraction time 3.0h, separate the obtained product, which is tomato seed oil.

Abstract

The invention relates to a method for preparing tomato seed oil. The method comprises the following steps of: performing microwave treatment on tomato seeds crushed to the particle size between 30 and 100 meshes, extracting by using supercritical CO2 for 1.0 to 3.0 hours, and separating a product, namely the tomato seed oil. The tomato seed oil prepared by the method has better property; unsaturated fatty acid content of the prepared tomato seed oil is about 5 percent higher than that of the tomato seed oil prepared by using the conventional solvent method; the fatty acid composition of the tomato seed oil better satisfies the needs of the human body; and more than 90 percent of the tomato seed oil is extracted from the tomato seeds.

Description

technical field [0001] The invention relates to a method for preparing oil, in particular to a method for preparing tomato seed oil. Background technique [0002] With the improvement of nutritional needs, people are not satisfied with only eating peanut oil, soybean oil, sesame oil, etc. There are many new vegetable oils that will become people's future edible oil. [0003] Oil is not only one of the main sources of life energy, but also has many important physiological functions. Vegetable oils are rich in linoleic acid, gamma-linolenic acid and other components, which are essential fatty acids that cannot be synthesized by the human body. Lack of linoleic acid can cause symptoms such as dry skin and growth retardation in babies. Y-linolenic acid can prevent and treat many diseases, such as senile dementia, hyperlipidemia, coronary heart disease and so on. [0004] my country is rich in tomato seed resources, and my country's tomato production is second only to the Unit...
