Problems solved by technology

However, the oil-seed oil production technology in the oil industry is still pre-pressing-leaching to extract crude oil, and then using high-temperature degumming, deacidification, decolorization and deodorization to produce salad oil, and this over-processed product removes most of the functional activity. The fat accompanying substances such as natural vitamin E, phytosterols, squalene, polyphenols, β-carotene, etc., and unique flavor substances reduce the original nutritional value of vegetable oil; at the same time, high temperature and chemical treatment lead to energy consumption of vegetable oil production High, high refining consumption, but also easy to produce harmful substances such as chloropropanol esters, trans fatty acids, benzopyrene, etc., unable to produce real high-quality vegetable oil

Abstract

The invention discloses an efficient preparation method of vegetable oil. The method comprises the following steps of: cleaning and selecting raw materials, namely, sequentially carrying out screening, air dense-medium fluidization dry separation and high-pressure ion atomization to separate non-oilseed impurities, oilseed mildew grains, shrunken grains and germinated grains; heat pump pre-conditioning, namely pre-conditioning cleaned oilseeds by using a solar heat pump system; solid-state radio frequency voltage stabilization type re-conditioning: re-conditioning the pre-conditioned oilseedsby utilizing a solid-state radio frequency voltage stabilization type device, the temperature of the re-conditioned oilseeds being 130-170 DEG C; antioxidant squeezing oil extraction, namely, adding ascorbic acid and a 2-phenyl chromone derivative into the re-conditioned oilseeds, and then squeezing the oilseeds; oil and fat refining, namely, heating the squeezed oil to 40-55 DEG C, adding an alcohol ester compound, and performing filtering and separating. With the method disclosed by the invention adopted, endogenous active substances in the oilseeds are greatly released, nutrition and flavorare more effectively reserved through low-temperature refining, the preparation of high-quality grease is realized, and the requirements of processing and production of various oil materials can be met.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a method for efficiently producing vegetable oil. Background technique [0002] my country is a big country in the production and consumption of edible vegetable oil. At present, the methods for producing vegetable oil from oil in my country mainly include pre-pressing-leaching, one-time hot pressing, puffing, low-temperature pressing, and aqueous enzymatic method. However, the oil-seed oil production technology in the oil industry is still pre-pressing-leaching to extract crude oil, and then using high-temperature degumming, deacidification, decolorization and deodorization to produce salad oil, and this over-processed product removes most of the functional activity. The fat accompanying substances such as natural vitamin E, phytosterols, squalene, polyphenols, β-carotene, etc., and unique flavor substances reduce the original nutritional value of vegetable oil; at the sa...
