Abstract
The invention discloses a process for extracting cottonseed salad oil. The process comprises the following steps: prefrying cottonseeds into cotton wool oil or leaching cotton wool oil; filtering; phosphating; performing alkali refining for de-acidification; adsorbing for bleaching; winterizing for degreasing; deodorizing; and refining into the cottonseed salad oil. The novel refining process of the cottonseed salad oil is simple and convenient. The process can be used for desolventizing effectively, so that the color of the salad oil is in a low level, the quality and the using performance of the salad oil are improved, the production cost is greatly reduced, the refining consumption rate of the cottonseed salad oil is reduced, and the process is suitable for large-scale industrial production.
Description
Technical field
The present invention relates to a kind of extraction process of cottonseed salad oil.
Background technology
Cottonseed salad oil method for refining complex process of the prior art, and the precipitation effect is undesirable, quality and the use properties of drawing grease of changing colour is bad, has greatly improved production cost, has improved cottonseed salad oil refining refining consumption rate, is unsuitable for large-scale industrial production.
Summary of the invention
Goal of the invention: the present invention is directed to deficiency, propose a kind of simple process, the extraction process of the cottonseed salad oil that can reduce production costs.
Technical scheme: the extraction process of a kind of cottonseed salad oil of the present invention comprises the steps:
(1) cottonseed pressed in advance to cotton wool oil or leach cotton wool oil;
(2) filter;
(3) phosphoric acid is processed;
(4) alkali-refining deacidification;
(5) adsorption bleaching;
(6) winterization degreasing;
(7) deodorization is processed;
(8) be refined into cottonseed salad oil.
As preferably, in described step (6), degreasing is to remove in Oleum Gossypii semen 20%～25% solid-state fat.
As preferably, add and account for the citric acid of oil mass 0.005%～0.01% in oil after described step (7) deodorization processing.
Beneficial effect: cottonseed salad oil method for refining simple process of the present invention, adopt effectively precipitation of the method, make the color and luster of salad grease in lower level, quality and the use properties of salad grease have been improved, greatly reduce production cost, reduce cottonseed salad oil refining refining consumption rate, be suitable for large-scale industrial production.
