“…Color pigments such as chlorophyll, carotenoids and other pigments from oil can be removed from the bleaching stage in the refining process (Wei and others ). Table shows the coefficients of the regression equation and P values for the significant terms in the suggested quadratic model for color reduction in bleached kenaf seed oil.…”

“…Crude oil is needed to transform to odorless, bland and oxidative stable edible oil through the refining process, which is preferable to the consumer (Kim and Choe ; Farhoosh and others ; Liu and others ). The valuable bioactive compounds might easily degrade during the refining process due to the high temperature applied (Škevin and others ; Wei and others ). Thus, parameters in the refining process are needed to optimize for different types of oils to minimize the losses of bioactive compounds and efficiently remove the undesirable components in the crude oil simultaneously.…”

Kenaf seed oil has been suggested to be used as nutritious edible oil due to its unique fatty acid composition and nutritional value. The objective of this study was to optimize the bleaching parameters of the chemical refining process for kenaf seed oil, namely concentration of bleaching earth (0.5 to 2.5% w/w), temperature (30 to 110°C) and time (5 to 65 min) based on the responses of total oxidation value (TOTOX) and color reduction using response surface methodology. The results indicated that the corresponding response surface models were highly statistical significant (P < 0.0001) and sufficient to describe and predict TOTOX value and color reduction with R 2 of 0.9713 and 0.9388, respectively. The optimal parameters in the bleaching stage of kenaf seed oil were: 1.5% w/w of the concentration of bleaching earth, temperature of 70°C, and time of 40 min. These optimum parameters produced bleached kenaf seed oil with TOTOX value of 8.09 and color reduction of 32.95%. There were no significant differences (P > 0.05) between experimental and predicted values, indicating the adequacy of the fitted models.

“…Therefore, one of the concerns in oil refining process is to reduce these color compounds in the crude oils. Neutralization, bleaching and deodorization are steps that neutralize FFA, reduce the yellow pigments and reduced the red pigment, respectively (Wei et al, 2015). As shown in Table 1 the refined oils had a clear with a light golden color compared to those of crude oils.…”

“…Camellia oil, produced from the seeds of the Camellia oleifera tree (C. oleifera seeds), is widely in food processing and cooking in China as well as some other Asian countries. The production of camellia seed oil reached almost 200,000 tons in 2011 (8). Camellia oil contains rich unsaturated fatty acids and antioxidative substances (9), similar to olive oil.…”

In this paper, vortex-assisted extraction using the ultraperformance liquid chromatography analysis method was performed to determine benzo[a]pyrene in camellia oil. Optimum results were obtained when 0.5 g of oil sample was used followed by vortex-assisted extraction for 10 min with 25 mL of acetonitrile. Chromatographic separation was performed on an Agilent ZORBAX Eclipse Plus C column (2.1mm×100mm, particle size 1.8 μm). The optimum mobile phase comprised 70% acetone and 30% water. The detection limit of benzo[a]pyrene was 0.2 μg/kg. The recoveries were in the range of 81.0-97.0%. The proposed method was simple and fast, and it provided high throughput in the determination of benzo[a]pyrene in an oil matrix sample.
