Abstract
The invention discloses a processing method for decreasing blue value amplification of fourth-grade rapeseed oil processed by imported rapeseeds. The processing method sequentially comprises the following steps of cleaning, softening and tempering, germ flattening, alkaline adding and cooking, pre-extraction, puffing, leaching, mixing, and refining. The processing method has the advantages that the 0.02-0.10% of 5-6% NaOH (sodium hydroxide) water solution is added into a germ slice to perform alkaline adding and cooking, the alkaline can generate neutralizing and soaping with acid materials in materials and crude oil in the cooking, subsequent pre-extraction, puffing, and leaching processes, the pigment substance in the crude oil is adsorbed and remained into the material, the influence to the increase of blue value caused by the heating test of fourth-grade rapeseed oil is decreased, and the problem of standard quality in the heating process of the fourth-grade rapeseed oil processed by the imported rapeseeds is solved.
Description
Technical field
The invention belongs to edible oil processing technique field, the processing method being specifically related to the blue valve amplification of a kind of level Four Oleum Brassicae campestris reducing imported oil rapeseed Processing。
Background technology
During imported oil rapeseed Processing refine level Four Oleum Brassicae campestris, the defective problem of heat run in the general quality inspection that there is level Four Oleum Brassicae campestris, after being in particular in the heating of level Four Oleum Brassicae campestris, blue valve increase exceeds standard。
The method of domestic current solution problems mainly has two kinds。One is to increase hargil bleaching workshop section, with the chlorophyll in active hargil adsorbed oil, reduces the blue valve in oils and fats。It is qualified that the level Four oil base that the method produces originally can reach " 280 DEG C of heat run blue valves increase index ", and shortcoming is the loss that oils and fats has 0.3～1%, with hargil abnormal smells from the patient in oils and fats, is not suitable for direct marketing, needs reprocessing。Two is adopt full refining method, through alkali refining, washing, dehydration, deodorize, adsorbs the pigment in oils and fats with alkali, reduces the blue valve in oils and fats。The product that the method produces is really three grades of oil。Shortcoming is that oil and fat refining loss is big, has the loss of 1.2～1.5%, and investment is big, need to build the production line of primary oil。
Summary of the invention
It is an object of the invention to overcome prior art defect, it is provided that the processing method of the blue valve amplification of a kind of level Four Oleum Brassicae campestris reducing imported oil rapeseed Processing。
The concrete technical scheme of the present invention is as follows:
