Abstract
The invention discloses a method for extracting vitamins from tomatoes. The method includes the following steps that firstly, tomatoes are selected and washed clean, the tomatoes are slit in an extracting protective solvent, and seeds are removed; secondly, shredded tomato pulp and the extraction protective solvent are added into a vacuum pulping machine together, and pulping is performed; thirdly, paste generated after pulping is added into a vacuum stirrer and stirred in vacuum; fourthly, materials generated in the third step are filtered, filter liquor stands still and is layered, and an organic phase is separated out; fifthly, water with pH smaller than 7 is added into the organic phase obtained in the fourth step, and vacuum stirring is performed for 2 or more hours; sixthly, standing and layering are performed, and a water phase is separated out; seventhly, the water phase is concentrated to be dry in vacuum, and vitamin crude products are obtained after freezing and drying. Due to the method, the vitamins in the tomatoes can be extracted; the extraction method is simple and suitable for being applied and popularized on a large scale; the content of the vitamins in extractives is high.
