Embodiment 1

[0014] Crush the tomato seeds, pack them with filter paper, put the packed filter paper tube into an extraction bottle, extract at 35°C and 8MPa for 180 minutes, and the flow rate of carbon dioxide during extraction is 24L / h. After the extraction, concentrate with a rotary evaporator to obtain tomato seed oil, and the extraction rate is 57.3%.

Embodiment 2

[0016] Crush the tomato seeds, pack them with filter paper, put the packed filter paper tube into an extraction bottle, extract at 50°C and 20MPa for 180 minutes, and the flow rate of carbon dioxide during extraction is 24L / h. After the extraction, concentrate with a rotary evaporator to obtain tomato seed oil, and the extraction rate is 59.1%.

Embodiment 3

[0018] The tomato seeds were crushed, packed with filter paper, and the packed filter paper tube was placed at 60° C. for 10 minutes. Then put it into an extraction bottle, extract at 35°C and 8MPa for 180 minutes, and the flow rate of carbon dioxide during extraction is 24L / h. Concentrate with a rotary evaporator after extraction to obtain tomato seed oil, and the extraction rate is 70.1%.

Abstract

The invention relates to a method for purifying edible vegetable oil and belongs to the fields of food additives and preparation methods thereof. The method for extracting tomato seed oil comprises the following steps: grinding tomato seeds, packaging by using filter paper, putting the packaged filter paper cylinder into an extraction bottle for extracting, concentrating by using a rotary evaporator after the extraction is ended, thereby obtaining the tomato seed oil. The experiment proves that high-quality products can be produced by the method disclosed by the invention, and the content of unsaturated fatty acids contained in the prepared tomato seed oil is about 2 percent higher than that of the traditional solvent method.

Description

technical field [0001] The invention relates to a purification method of edible vegetable oil, which belongs to the field of food additives and preparation methods thereof. Background technique [0002] Tomato is an important vegetable crop in the world. In 2008, its output reached 130 million tons, one-third of which was used for industrial production, and a large amount of waste (3-5% of tomato fresh weight) was generated during tomato deep processing. , 60% of which are tomato seeds. These wastes are mainly sold at low prices as primary feed. Therefore, how to efficiently utilize these wastes has become an urgent problem for tomato paste processing enterprises. [0003] Tomato seeds contain 20% to 36.9% (dry weight) of oil, which is higher than soybean oil, and unsaturated fatty acids account for more than 70% of oil; in addition, it is also rich in bioactive components such as tocopherol and phytosterol, It is a high-quality edible vegetable oil resource. If these di...
