Problems solved by technology

[0003] At present, the extraction methods of vitamin E at home and abroad mainly include chemical method, supercritical method, ion exchange method and biological method. Among them, the chemical method has the advantages of short extraction time and simple process, but consumes a lot of organic solvents, which is easy to cause the loss of vitamin E; The critical process is simple, the extraction rate is high, but the investment is large and the cost is high; the ion exchange method is simple, the loss rate is small, but the solvent consumption is large

Embodiment 1

[0019] Example 1: A method for extracting vitamin E from the deodorized distillate of tomato seed oil based on an enzymatic method, adding 10 parts by weight of the deodorized distillate and 30 parts by weight of water into a container, stirring at 28 ° C for 3 minutes, and then Add 3.2 parts by weight of lipase, hydrolyze for 25 minutes, then add 4.8 parts by weight of lipase and methanol to the container according to the volume-to-weight ratio of 3:1, stir and catalyze the reaction for 50 minutes, then remove moisture, separate layers, and take The supernatant liquid; adding 16 times the weight of n-hexane to the supernatant liquid for extraction once, and then washing it once with deionized water; after washing with water, concentrating to obtain the concentrate of natural vitamin E.

[0020] The content of natural vitamin E in the concentrate is 43.3%, and the recovery rate of natural vitamin E from the deodorized distillate can reach 92.3% through the above steps.

Embodiment 2

[0022] Example 2: A method for extracting vitamin E from the deodorized distillate of tomato seed oil based on an enzymatic method, adding 10 parts by weight of the deodorized distillate and 32 parts by weight of water into a container, stirring at 28.2 ° C for 3.1 min, Then add 3.4 parts by weight of lipase, hydrolyze for 25.2 minutes, then add 5 parts by weight of lipase and methanol to the container according to the volume-to-weight ratio of 3.2:1, stir and catalyze the reaction for 52 minutes, then remove the water and separate layers , take the supernatant; add 16.2 times the weight of n-hexane to the supernatant to extract twice, then wash twice with deionized water; wash and concentrate to obtain the concentrate of natural vitamin E.

[0023] The content of natural vitamin E in the concentrate is 43.5%, and the recovery rate of natural vitamin E from the deodorized distillate can reach 92.5%.

[0024] The aforementioned lipase is 45.2 U / mg lipase.

Embodiment 3

[0025] Example 3: A method for extracting vitamin E from the deodorized distillate of tomato seed oil based on an enzymatic method, adding 10 parts by weight of the deodorized distillate and 34 parts by weight of water into the container, stirring at 28.4 ° C for 3.3 minutes, Then add 3.6 parts by weight of lipase for 25.4 minutes of hydrolysis, then add 5.2 parts by weight of a mixture of lipase and methanol in a volume-to-weight ratio of 3.4:1 to the container, stir and catalyze the reaction for 54 minutes, then remove water and separate layers , take the supernatant; add 16.4 times the weight of n-hexane to the supernatant to extract 3 times, then wash 3 times with deionized water; wash and concentrate to obtain the concentrate of natural vitamin E.

[0026] The content of natural vitamin E in the concentrate is 43.7%, and the recovery rate of natural vitamin E from the deodorized distillate can reach 92.7% through the above steps.

[0027] The aforementioned lipase is 45.4...

Abstract

The invention discloses a method for extracting Vitamin E from a tomato seed oil deodorized distillate based on an enzymic method. The method is characterized by mainly comprising the following steps of enzymolysis, extraction separation, washing and concentration, wherein enzymolysis is performed two times, lipase is used for the first-time enzymolysis, and a lipase and methyl alcohol mixture is used for the second-time enzymolysis. Compared with the prior art, the method has the advantages of being in simple in technology, high in extraction rate and the like.

Description

technical field [0001] The invention relates to the field of food, and mainly relates to a method for extracting vitamin E from tomato seed oil deodorized distillates based on an enzymatic method. Background technique [0002] Tomatoes have long been known and widely grown as edible fruits and vegetables. China's tomato industry is developing rapidly. It is understood that the annual output of tomato sauce in Xinjiang is increasing day by day. Tomato seeds have been turned from waste to treasure in Xinjiang's scientific and technological development and research and production of innovative enterprises, and have become raw materials to guide the industry in one fell swoop. Tomato seeds are mostly used to produce high-grade edible oil. In Xinjiang alone, there is an output of 4,000 tons, and the output value can reach about 1 billion. Tomato seed oil is rich in vitamin E, lycopene, β-carotene and phytosterols, which has attracted the attention of consumers. The vitamin E co...
