Problems solved by technology

[0008]On the other hand, although it is expected to obtain or retain more nutrients when refining sunflower oil, this also leads to poor oxidation stability of sunflower oil, That is, the acid value (AV) and peroxide value (PV) of crude oil are likely to be high
For example, if only degumming and dewaxing treatment is used to preserve the flavor, the shelf life of flavored sunflower oil will have the risk of exceeding the quality index, and the flavor will easily be oxidized; Deodorization, although acid value (AV) and peroxide value (PV) indicators can be well controlled, it will have a great impact on flavor, because alkali refining will introduce alkali taste and soap taste formed by neutralization reaction, while Deodorization While removing PV, flavor substances will also be removed at the same time

Embodiment

[0136] The present invention will be described in detail through examples below.

[0137] Examples and comparative examples

[0138] operating conditions

[0139] Heat sunflower oil to 75°C, add 0.02% of the oil weight phosphoric acid or citric acid (mixed in a certain proportion with water) and mix evenly, then enter the acid reaction tank to react for 80 minutes, then cool down to the alkali refining temperature through heat exchange, and evenly Add the NaOH solution of a certain amount of alkali and a certain concentration of lye into the alkali reaction tank for 12 minutes (the amount of alkali in the embodiment and the comparative example table is based on the theoretical amount of alkali as a contrast, and the amount is more or less on the basis of the theoretical amount of alkali), and then After heating to 85°C, the soap is removed by a disc centrifuge, centrifuged at a certain centrifuge outlet pressure, and then the centrifuged oil phase is washed with 5% water of...

Abstract

The invention relates to sunflower seed oil, which is sunflower seed oil refined oil obtained by refining crude sunflower seed oil, and the acid value AV1 value of the refined oil is reduced by more than 50% compared with the AV0 value of the crude oil. The reduction rate of the peroxide value PV1 value of the refined oil compared with the peroxide value PV0 value of the crude oil is 52% or more; on the basis of the content of sterol in the crude oil, the reduction rate of the content of sterol in the refined oil is 4.1% or less compared with the content of sterol in the crude oil.

Description

technical field [0001] The invention belongs to the technical field of oils and fats, and in particular relates to a vegetable oil and a preparation method thereof, and more specifically relates to sunflower oil and a preparation method thereof. Background technique [0002] Sunflower oil is golden in color, clear and transparent, and has a delicate smell. It is an important edible oil. It contains a large amount of essential nutrients, which can promote the regeneration and growth of human cells, protect skin health, and reduce the accumulation of cholesterol in the blood. It is a high-grade nutritional oil. [0003] Sunflower oil is rich in oleic acid and linoleic acid, the content of unsaturated fatty acid is as high as 85%, and it is rich in oil accompanying α-tocopherol and phytosterol. In particular, the unique sweet sunflower flavor of sunflower oil is very unique and highly accepted by consumers. Therefore, in the process of refining or extracting sunflower oil, it...
