Abstract

The present invention relates to a kind of making method that is used for foodstuffs industry for plam oil and plastic fat, it is a raw material with China's abundant inexpensive oleum sapii and other vegetables oil, after the depickling of coming unstuck, they are mixed by a certain percentage mutually, with sodium alkoxide do catalyzer through the deodorization of transesterify rear decoloring produce for plam oil or through the deodorization of transesterify rear decoloring again the winterization branch obtain through refining and replace palm and plastic fat.The present invention's plam oil of prepared generation and its physical and chemical index of plastic fat all reach domestic or international standard, have the advantages that raw materials cost is low, making processes is easy, with short production cycle.

Description

A kind of generation plam oil and the making method of plastic fat

The present invention relates to a kind of making method for plam oil and plastic fat that is used for foodstuffs industry, wherein can be used as frying oil in the foodstuff production for plam oil, also can be used as a kind of table oil, plastic fat then is the special fat in cake, the pan work.

Palm olein oil is the low melting point part extracted from temperate plant oil palm oil (fusing point≤24 ℃), it is the wider important source material of a kind of purposes in the food processing and production industry, because its place of production scope is narrower, ultimate production is lower, make that world's palm oil sources is in short supply, hold high on the price, far can not satisfy the demand of foodstuffs industry.For this reason, many countries remedy above-mentioned deficiency with the surrogate-Dai plam oil of palm olein oil, have physics-chem characteristic near palm olein oil for plam oil, and it can be widely used in instant noodles processing and wait other fried food production field.

At present, producing for palmitic method of generally adopting is: with Rice pollard oil, cotton oil, rape oil, soybean wet goods is that raw material is that raw material divides the part that proposes to be similar to palm olein oil through winterization through selective hydration or with animal and vegetable oil such as butter, lard, mother-in-law sieve's fat, obtains for plam oil through refining again.In addition, also have the solid fat of carrying with cotton oil, Rice pollard oil winterization branch mix with sesame oil, rape oil the back refining make the generation palmitic method.Above-mentioned making method has the following disadvantages: one, and raw materials cost is higher; Its two, the manufacture craft more complicated, the production cycle is long; Its three, its structure of the processing units of corresponding configuration is also comparatively complicated, has relatively high expectations.

On the other hand,, in grocery trade, also have purposes widely, and had the multiple method of synthesizing and producing plastic fat with regard to plastic fat.

Task of the present invention is to overcome above-mentioned the deficiencies in the prior art part and provides the generation that a kind of raw materials cost is low, making processes is easy palmitic making method.

The scheme that realizes the above-mentioned task of the present invention is as follows: with the depickling pre-treatment of coming unstuck respectively of oleum sapii and other vegetables oil, thereafter with them by 1: 2-4(is by weight) proportioning mix, under vacuum (vacuum tightness is not less than the 720mm mercury column) condition, heat to 60-120 ℃, and adding proper catalyst, charge into an amount of nitrogen simultaneously, make its reaction for some time after, add hot water and stop, washing rear decoloring, deodorization promptly make for plam oil.

The temperature of reaction of heating in the such scheme is got 85-98 ℃ usually, and catalyzer is sodium methoxide solution (concentration 23-29%), the proportional quantity of adding be 0.25-0.5%(by weight).

Another task of the present invention be to provide the low making processes of a kind of raw materials cost easy can obtain making method simultaneously for plam oil and plastic fat.

Above-mentioned task is realized by following scheme: with the depickling pre-treatment of coming unstuck respectively of oleum sapii and other vegetables oil, thereafter with them by 1: 0.4-1.5(is by weight) proportioning mix, under vacuum (vacuum tightness is not less than the 720mm mercury column) condition, heat to 60-120 ℃, and adding proper catalyst, charge into an amount of nitrogen simultaneously, after making its reaction for some time, adding hot water stops, washing rear decoloring, deodorization, carry out winterization again under 26-28 ℃ of temperature, temperature filtration obtains for plam oil (liquid phase) and plastic fat (solid phase).

The temperature of reaction of heating in the such scheme is got 85-98 ℃ usually, catalyzer be proportional quantity that sodium methoxide solution (concentration 23-29%) adds be 0.25-0.5%(by weight), the time of winterization is 2-3 hour.

According to such scheme plam oil of prepared generation; the little Huang of product color, free from extraneous odour, its main physical and chemical index all reaches the Ministry of Commerce " the edible palm oil tentative standard " issued; and build the refining liquid plam oil that reaches edible oil company and be close with extra large emperor's board plam oil and Malaysia, ask for an interview table 1.Its solid fat index of the plastic fat that the present invention makes all meets international standard, has good physical and chemical index, asks for an interview table 2.

The present invention has following advantage, and 1, to have made full use of china natural resources abundant, cheap sapium fat resource has reduced and has made palmitic raw materials cost of generation; 2, simplified palmitic production process of generation, production technique is simple, and is with short production cycle, and the yield of product is higher relatively; 3, the device structure of corresponding configuration is simplified, and facility investment is few, has reduced the production cost of whole prod.
