Abstract
The invention provides a method for reducing oil color by utilizing optical filters to screen single-wavelength light to irradiate soybean oil in an oil refining process, and aims to find out monochromatic light to effectively reduce oil color while reducing usage of active white light on the premise of guaranteeing oil quality. Since oil color is generated from carotene in oil, carotenoids are affected by different factors, and change according to different rules. Particularly, factors such as oxygen, light and heat can affect stability of the carotenoids destructively, so that oil color is reduced. The monochromatic light VIS-450 screened out can effectively destruct the carotenoids on conditions with current strength ranging from 13A to 21A and temperature ranging from 25 DEG C to 30 DEG C within a time range of 2-4 hours, so that oil color is reduced. In addition, the monochromatic light screened out on the conditions have low affection to oil quality.
Description
Technical field:
The present invention relates to the food oils manufacture field, be specifically related to the method for a kind of novel reduction soybean oil color and luster in the oil and fat refining process.
Background technology:
The invention provides in a kind of oil alkali refining process and filter out single wavelength light shines to reduce grease color to soybean oil method by spectral filter, be intended to seek a kind of monochromatic ray under the prerequisite that guarantees oil quality, can effectively reduce the consumption that grease color reduces atlapulgite simultaneously.
The color and luster of grease is mainly produced by carotenoid in the grease, and carotenoid is subjected to the impact of different factors, causes it different Changing Patterns to occur.Wherein the factors such as oxygen, light, heat all can produce damaging influence to the stability of carotenoid, thereby the color and luster of grease is reduced.
The monochromatic ray of certain wavelength that the present invention filters out, thus the color and luster that carotenoid reduces grease can effectively be destroyed, and it is less on the quality impact of grease to endeavour the light of the wavelength that requirement screens.
Summary of the invention:
In order to overcome the defective of conventional decolouring production soybean oil, adapt to the modern technologies development, the demand of satisfying the market, we have proposed a kind of method of improved reduction grease color:
The soybean oil lucifuge is placed, preheating, and the screening optical wavelength is carried out rayed in 300-500nm, and 13-21A reacts in strength of current, and the reaction times, then temperature of reaction got reacted grease at 25 ℃-35 ℃, surveys its color and luster at 2-4h;
Useful point of the present invention is:
1, use fluorescent lamp and shine, and then reduced oil loss, decolorizing effect and oil quality are better.
2, only using fluorescent lamp in the reaction process is decolorization condition, has made things convenient for the follow-up refining of grease, has reduced simultaneously the processing costs to carclazyte.
Step of the present invention is as follows:
Step 1: the raw material lucifuge is placed, and with screening optical wavelength in the 300-500nm soybean oil is shone;
Step 2: respectively under 5-21A strength of current, under certain temperature and wavelength, illumination for some time is carried out decoloring reaction, then gets reacted grease, surveys its color and luster, determines intensity of illumination with a certain amount of soybean oil;
Step 3: a certain amount of soybean oil is shone with optimal light intensity, select 15-35 ℃ of bleaching temperature, under certain light application time, carry out decoloring reaction, then get reacted grease, survey its color and luster, determine bleaching temperature;
Step 4: a certain amount of soybean oil is shone with optimal light intensity, select the 0-4h bleaching time, under certain intensity of illumination and temperature, carry out decoloring reaction, then get reacted grease, survey its color and luster, determine bleaching time;
Step 5: a certain amount of soybean oil is shone with optimal light intensity, select screening optical wavelength in the 300-500nm, under the temperature and time condition of determining, carry out decoloring reaction, then get reacted grease, survey its color and luster, determine optical wavelength.
Key of the present invention is determining of decolorization condition, comprises intensity of illumination, bleaching temperature, time and wavelength of light.According to the optimal processing parameter test, obtain bleached oil, survey its color and luster in country and soybean oil requirement, also proved the utility value of natural light.
Embodiment:
Embodiment one: the step of present embodiment is as follows:
