2 results and analysis
2.1 determination of the maximum absorption wavelength
The wavelength of crude oil is scanned within the range of 400-700 nm by using distilled water as a reference, and the maximum absorption wavelength is determined, and the result is shown in figure 1. As can be seen from FIG. 1, the maximum absorption wavelength of camellia oil is 455 nm. The maximum absorption wavelength may be different due to different oil products, and the result is different from other documents, the maximum wavelength measured by Wujianbao et al is 430nm, and the maximum wavelength measured by the Sun Shi Fang is 480 nm.
2.2 analysis of Single-factor test results
2.2.1 Effect of different decolorizing agents on decolorization Rate
Three decolorants, namely activated clay, attapulgite and activated carbon, were selected for carrying out a decoloration test under the conditions of decolorant dosage of 2%, decoloration temperature of 80 ℃, decoloration time min and stirring speed of 100r/min, and the results are shown in fig. 2. As can be seen from FIG. 2, the decolorization ratio of the three decolorizers is 93%, and the decolorization effect has no significant difference. Therefore, activated clay is selected as the bleaching agent in view of the cost of practical production. And secondly, taking harmful substances such as benzopyrene which cannot be removed by the clay into consideration in the production process by using the activated carbon, so that the clay and the activated carbon are required to be compounded for use.
2.2.2 Effect of Compound decolorizer ratio on decolorization Rate
Selecting argil under the conditions that the addition amount of a compound decolorizing agent is 2 percent, the decolorizing temperature is 80 ℃, the decolorizing time is 15min and the stirring speed is 100 r/min: the ratio of the activated carbon is 20:1, 10:1 and 5: 1. the results of the decolorization tests were shown in FIG. 3 for 4:1, 3:1, 2:1, and 1: 1. As can be seen from FIG. 3, there is no significant difference between the decoloring effects of the compound decoloring agents in different proportions, so from the viewpoint of production economy, clay is selected: the ratio of activated carbon was 20: 1.
2.2.3 Effect of Decoloration temperature on Camellia oil Decoloration
Under the conditions that the ratio of the activated clay to the activated carbon is 20:1, the addition amount of a decolorizing agent is 2%, the stirring speed is 100r/min, and the decolorizing time is 15min, different decolorizing temperatures of 60, 70, 80, 90 and 100 ℃ are selected for carrying out a decolorizing test, and the result is shown in figure 4. As can be seen from fig. 4, the decoloring rate shows a trend of increasing significantly with the increase of the decoloring temperature, and when the temperature reaches 90 ℃, the decoloring rate reaches 94.66%, and then the decoloring rate does not change significantly. The decolorizer can be accelerated to contact with the colored substances of the oil by increasing the decolorization temperature, and the decolorization of the oil is accelerated. Too high temperature can also accelerate the oxidation of the tea oil and influence the quality of the tea oil. Thus temperatures generally do not exceed 100 ℃ in practice. Therefore 90 ℃ was chosen for subsequent orthogonal experiments.
2.2.4 Effect of Decoloration time on Decoloration
The decolorization test is carried out by selecting different decolorization temperatures of 5, 10, 15, 20 and 25min under the conditions that the ratio of activated clay to activated carbon is 20:1, the addition amount of a decolorizer is 2%, the decolorization temperature is 80 ℃ and the stirring speed is 100r/min, and the result is shown in figure 5. As can be seen from FIG. 5, the decolorization rate tended to increase significantly with the increase in the decolorization time, and the decolorization rate reached 95.03% at the decolorization time of 20min, and there was no significant difference thereafter. In the actual production process, the longer the time is, the tea oil can be slowly oxidized, and the production time generally does not exceed 30min, so the decolorization time is selected to be 20min for carrying out the subsequent orthogonal test.
2.2.5 Effect of decolorizing agent addition on decolorizing ratio
The decolorization test is carried out by selecting different addition amounts of 1%, 2%, 3%, 4%, 5% and 6% under the conditions of the ratio of the clay to the active carbon being 20:1, the decolorization temperature being 80 ℃, the stirring speed being 100r/min and the time being 15min, and the result is shown in figure 6. As can be seen from FIG. 6, the amount of the decoloring agent added significantly affects the decoloring effect. When the addition amount of the decoloring agent is in a range of 1-5%, the decoloring rate is increased along with the increase of the addition amount, when the addition amount of the decoloring agent is 1%, the decoloring rate is only 80.72%, when the use amount of the decoloring rate reaches 5%, the decoloring rate reaches 95.82%, and when the addition amount of the decoloring agent is 6% and 5%, no significant difference exists, so that an orthogonal test is carried out by selecting 5% of the use amount of the additive.
2.2.6 influence of stirring speed on decolorization rate of refined camellia oil in decolorization process
Under the conditions of the ratio of activated clay to activated carbon being 20:1, the addition of a decolorizing agent being 2%, the decolorizing temperature being 80 ℃ and the decolorizing time being 15min, different stirring speeds of 50, 100, 150, 200 and 250r/min are selected for carrying out decolorization tests, and the results are shown in figure 7. As can be seen from FIG. 7, the decoloring rate tends to increase and decrease with the increase of the decoloring time, and the decoloring rate reaches a maximum of 93.69% at a decoloring stirring speed of 100r/min, and decreases as the stirring speed continues to increase. The proper stirring can ensure that the decolorizing agent is fully contacted with the tea oil, and the decolorizing efficiency is improved. However, the stirring speed cannot be too high because the oxidation of the tea oil is accelerated by vigorous stirring, so that the decoloring stirring speed of 100r/min is selected for the subsequent orthogonal test.
2.3 analysis of orthogonal test results
According to the results of the single-factor test, the four-factor three-level orthogonal test analysis is carried out on the test by selecting the decoloring temperature (80, 90 and 100 ℃), the decoloring time (15, 20 and 25min), the decoloring agent adding amount (4, 5 and 6 percent) and the stirring speed (50, 100 and 150 r/min).
The results of the orthogonal experiments are shown in table 2. As can be seen from Table 2, the visual optimum combination is A2B2C3D1The decolorization ratio is 98.46 percent, and the range of the factors is RA>RC>RB>RDNamely, the factor A (decolorizing temperature) has the largest influence on the decolorizing effect of the camellia oil, and the factor C (decolorizing agent adding amount), the factor B (decolorizing time) and the factor D (stirring speed) have the smallest influence. The optimum combination of decolorizing conditions was obtained from the test results as A3B3C3D1Inconsistent with visual combination, after performing a verification test, A3B3C3D1The result of the verification test of (1) is 98.22%, and has no significant difference with the result of the direct optimal combination. From an economic point of view A2B2C3D1The combination is more reasonable. The optimum decolorization conditions for tea oil are therefore: the decoloring temperature is 90 ℃, the decoloring time is 20min, the addition amount of a decoloring agent is 6 percent, and the stirring speed in the decoloring process is 150 r/min.
