Low-trans blend (LTB) was produced from the fractionated mustard oil (solid phase, S-MO) and palm stearin (PS) through lipase-catalyzed reaction, in which linoleic acid (LA) was intentionally incorporated. For optimizing the reaction condition, response surface methodology (RSM) was employed with three reaction variables such as substrate mole ratio of S-MO to PS (X1), reaction temperature (X2) and reaction time (X3). The predictive models were adequate and reproducible due to no significant lack of fit and the P-value of the model was very small ω6/ω3 ratio, and satisfactory level of coefficient of determination (R2 = 0.89) for ω6/ω3 ratio. The ω6/ω3 ratio of LTB was affected by substrate mole ratio and reaction temperature but reaction time had no significant effect. For considering the ω6/ω3 ratio, the optimum condition found 1:1.7 substrate mole ratio, 61.42 _ reaction temperature and 25.85 h reaction time.

Significant Term

The main purpose of the study was to produce esterified solid fat (ESF) from fractionated rapeseed oil and palm   stearin through lipase-catalyzed reaction. The response surface methodology (RSM) was applied for optimization of   three reaction factors such as substrate mole ratio, enzyme percent, and reaction time. The design was adequate   and reproducible due to satisfactory levels of coefficient of determination (R2, 0.98) for both cases and coefficient   variation (CV, 4.06 for SFC at 10 °C and 7.95 for SFC at 30 °C, respectively). The substrate mole ratio was the   significant term for affecting the response of SFC (P<0.05) rather than reaction time and enzyme percent. Based on   ridge analysis, the production of ESF with SFC 51.48 ±0.94 % at 10 ºC would be predicted by the combinations of   optimized 24.07 h reaction time, 10.66 % enzyme and 1: 1.52 substrate mole ratios. On the other hand, the SFC of   21.44±0.83 at 30 ºC would be predicted by the combinations of optimized 24.37 h reaction time, 10.23 % enzyme and   1: 1.5 substrate mole ratios. The ESF contained mainly of palmitic (45.1%), oleic (40.8%), linoleic (5.6%) and stearic   (4.5%) acids, respectively. The total sterol and tocopherol contents of ESF were 243.27 mg/100g and 19.26 mg/100 g,   respectively. Therefore, these results in this study suggested that RSM can be used to optimize the lipase-catalyzed   synthesis of ESF with suitable physical characteristics.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11040   J.

Optimal Conditions

Linoleic acid (LA) was extracted and purified from Idesia polycarpa Maxim.var. vestita Diels (IPMVVD) oil by urea adduction fractionation, and the response surface methodology (RSM) was successfully employed to optimize the process. The optimal conditions for purification of LA from mixed fatty acids by urea adduction fractionation were as follows: a weight ratio of 4.4:1.0:1.0 (w/w/w) of methanol/urea/mixed fatty acids, a temperature of -5°C and a time of 24.6 h, respectively. Under these conditions the experimental LA yield (48.65%) agreed with the predicted value and the purity of LA was 98.74%.
