Corn oil with high vitamin E and phytosterin contents and production method thereof

Abstract

The invention belongs to the field of vegetable oil refinement, in particular relates to a corn oil with high vitamin E and phytosterin contents and a production method thereof. 100g of corn coil contains 90mg to 120mg of vitamin E and 90mg to 1300mg of phytosterin. The production method of the corn oil comprises the following steps: arranging a drip catcher behind a deodorizing tower to collect deodorized distillate; removing impurities; distilling the deodorized distillate to remove dissociative fatty acid; adding alcohol to mother liquid after removing the fatty acid to further remove remnant fatty acid; using a decoloring agent to absorb and decolor the mother liquid; and returning the obtained qualified treatment liquid to product oil, uniformly mixing the qualified treatment liquid and the product oil, storing and packaging the mixture. Compared with the corn oil prepared by the traditional refinement technology, the corn oil is improved in the vitamin E and phytosterin contents by 30 to 50 percent.

Description

technical field [0001] The invention belongs to the field of vegetable oil refining, and in particular relates to a corn oil product with high vitamin E and phytosterol content and a production method thereof. Background technique [0002] Corn oil is a vegetable oil made from corn germ. It is a high-quality edible vegetable oil, a better cooking oil, and the best oil for processing food. In addition, the mixed corn oil made by mixing corn oil with solid oil (such as palm oil) can be widely used in rice cakes and various convenience foods. Fast food, instant noodles, and snacks made with corn oil have good taste and long shelf life. long. [0003] Corn oil mainly contains 86% unsaturated fatty acids, of which linoleic acid accounts for 55%, oleic acid accounts for 30%, and also contains vitamin E, vitamin A, phytosterols, lecithin, coenzyme, β-carotene and other nutrients. Among them, linoleic acid is an essential fatty acid for the human body, which is an integral part of...

Problems solved by technology

[0009] The phytosterols and natural vitamin E contained in the distillate of the above-mentioned deodorization process are often not further extracted due to separation difficulties, but are sold cheaply as waste materials together with free fatty acids, resulting in waste of resources; after individual companies separate the free fatty acids, Then carry out cumbersome steps such as cold analysis, filtration separation, dehydration, and four-stage molecular distillation to extract vitamin E from it, which requires complex complete sets of equipment, workshops and large investments.
