Abstract

The invention discloses a method for retaining vitamin E in sunflower seeds by ultra-short time low-temperature deodorization, which comprises the steps of filtering crude sunflower seed oil to remove mechanical impurities, adding a mixture of phosphoric acid and citric acid into the crude sunflower seed oil at 70-80 ℃ to remove phospholipid in the oil and passivate metal ions; then adding alkali; then, removing soapstock generated by alkali refining by using a high-speed centrifuge, and washing with water to reduce residual soap in the oil; then carrying out dewaxing and decoloring treatment; and finally, heating the oil temperature under vacuum, and removing free aldehyde ketonic acid by steam distillation to reduce the acid value and achieve the first-class oil standard. The method is simple and convenient and easy to operate; the content of the refined vitamin E reaches more than 650 mg/kg.

Description

Method for retaining vitamin E in sunflower seeds by ultra-short-time low-temperature deodorization
Technical Field
The invention relates to a method for retaining vitamin E in sunflower seeds by ultra-short time low-temperature deodorization.
Background
Although the sunflower seed oil is not a new oil product, the consumption of the sunflower seed oil is increased year by year in recent years, and the sunflower seed oil is well favored by wide consumers. The sunflower seed oil contains various substances beneficial to human bodies, such as sterol, vitamins and the like, wherein the content of vitamin E is the highest in all vegetable oils, but the loss of the vitamin E after refining is serious.
Disclosure of Invention
The invention aims to provide a method for keeping vitamin E in sunflower seeds by ultra-short time low-temperature deodorization with high vitamin E content after refining.
The technical solution of the invention is as follows:
a method for keeping vitamin E in sunflower seeds by ultra-short time low-temperature deodorization is characterized by comprising the following steps: comprises the following steps: filtering crude sunflower seed oil to remove mechanical impurities, adding a mixture of phosphoric acid and citric acid into the crude sunflower seed oil at 70-80 ℃ to remove phospholipids in the oil and passivate metal ions; then adding alkali; then, removing soapstock generated by alkali refining by using a high-speed centrifuge, and washing with water to reduce residual soap in the oil; then carrying out dewaxing and decoloring treatment; and finally, heating the oil temperature under vacuum, and removing free aldehyde ketonic acid by steam distillation to reduce the acid value and achieve the first-class oil standard.
The addition amount of the mixture of the phosphoric acid and the citric acid is 0.05-0.15% of the weight of the sunflower seed crude oil.
The mass ratio of the phosphoric acid to the citric acid in the mixture of the phosphoric acid and the citric acid is as follows: phosphoric acid citric acid =1: 2-3.
The rotating speed of the high-speed centrifuge during centrifugal treatment is 5800-6300 r/min. The vacuum degree of the vacuum is 1.3-1.8 mBar. Under vacuum, heating the oil to 230-240 deg.c, and distilling with steam in 20-30 min to eliminate free aldonic acid.
The method is simple and convenient and easy to operate; the content of the refined vitamin E reaches more than 650 mg/kg.
The present invention will be further described with reference to the following examples.
Detailed Description
A method for retaining vitamin E in sunflower seeds by ultra-short time low-temperature deodorization comprises the following steps: filtering crude sunflower seed oil to remove mechanical impurities, adding a mixture of phosphoric acid and citric acid into the crude sunflower seed oil at about 75 ℃ to remove phospholipids in the oil and passivate metal ions; then adding alkali by a conventional shore method; then, removing soapstock generated by alkali refining by using a high-speed centrifuge, and washing with water to reduce residual soap in the oil; then carrying out dewaxing and decoloring treatment; finally, under the vacuum of about 1.5mBar, the oil temperature is heated to about 235 ℃, and free aldonic acid is removed by steam distillation within 30 minutes, so that the acid value is reduced, and the first-grade oil standard is achieved.
The addition amount of the mixture of the phosphoric acid and the citric acid is about 0.1% (0.05-0.15%) of the weight of the sunflower seed crude oil.
The mass ratio of the phosphoric acid to the citric acid in the mixture of the phosphoric acid and the citric acid is as follows: phosphoric acid citric acid =1: 2-3.
The rotating speed of the high-speed centrifuge during centrifugal treatment is about 6000 r/min.
