Problems solved by technology

The physical method usually uses mechanical force to squeeze the raw material to produce oil. The process is simple, the oil yield is low, and the residual oil of the oil residue is high, which is easy to cause a certain degree of waste; the chemical method usually takes a long time to extract and consumes a lot of solvent. High chemical residues of solvents, resulting in poor quality oils

Embodiment 1

[0032] The preparation method of tomato seed oil comprises the following steps:

[0033] (1) select the tomato seeds produced in the current year, crush them to 40 meshes, put them into a hot air dryer and dry them with 800°C hot air to obtain tomato seeds with a moisture content of 3wt%;

[0034] (2) Extraction of crude oil: the tomato seeds with a moisture content of 3wt% were subjected to supercritical CO 2 Fluid extraction, adding entrainer during the extraction process, in which CO 2 The flow rate is 15kg / h, the flow rate of the entrainer is 0.9kg / h, the extraction pressure is 35Mpa, the extraction temperature is 36°C, and the extraction time is 2h to obtain crude oil;

[0035] (3) Hydration degumming: mix crude oil and acid solution in a mass ratio of 100:5, stir at 300 rpm for 30 minutes, and centrifuge to obtain degummed oil;

[0036] (4) Decolorization: Stir and mix the degummed oil and activated carbon (50 mesh activated carbon produced by Qingdao Jiade Filter Mate...

Embodiment 2

[0042] It is basically the same as Example 1, the difference is only that: in the step (2), the entrainer is composed of 1,2-propanediol and glycerin, wherein the flow rate of 1,2-propanediol is 0.45kg / h, and the flow rate of glycerin is 0.45kg / h. The tomato seed oil of embodiment 2 can be obtained.

Embodiment 3

[0044] It is basically the same as Example 1, the difference is only that: in the step (2), the entrainer is composed of 1,2-propanediol and 1,3-propanediol, wherein the flow rate of 1,2-propanediol is 0.45kg / h, 1, The flow rate of 3-propanediol is 0.45kg / h. The tomato seed oil of embodiment 3 can be obtained.

Abstract

The invention discloses tomato seed oil and a preparation method thereof. The preparation method includes following steps: (1), crushing and drying tomato seeds to obtain tomato seeds with water content of 1-5 wt%; (2), subjecting the tomato seeds with the water content of 1-5 wt% to supercritical CO2 fluid extraction, and adding an entrainer in the extraction process to obtain crude oil; (3), mixing the crude oil and acid liquid according to a mass ratio of (95-105):(2-7), stirring for 25-35 min, and centrifugally separating to obtain degummed oil; (4), decoloring; (5), filtering. In the extraction process, the preparation method is mature in process, easy to operate and environment-friendly, the tomato seed oil has the advantage of high yield, purity and quality and has a healthcare function of lowering three highs.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a tomato seed oil and a preparation method thereof. Background technique [0002] Tomato, Latin scientific name: Solanumlycopersicum, alias tomato, foreign persimmon, ancient name June persimmon, happy report three yuan,. In Peru and Mexico, it was originally called "wolf peach". The fruit is rich in nutrition and has a special flavor. It can be eaten raw, cooked, processed into tomato sauce, juice or canned as a whole fruit. Tomato is one of the most widely cultivated fruit vegetables in the world. [0003] Tomato seed oil is a natural high-quality edible oil extracted and refined from tomato seeds. Tomato seed oil is a high linoleic acid edible oil, and is rich in lycopene, vitamin E and vitamin A precursor carotene. Tomato seed oil extracted from fresh tomato seeds, lycopene and various oil-soluble vitamins can be effectively absorbed by the human body. Tomato seed...
