Figure 4: Effect of addition of solvents in the hydrolysis yield of macauba kernel oil at 55°C, oil to solvent mass ratio of 1 : 1, 400 rpm, buffer to oil mass ratio of 1 : 2, buffer pH of 8.0, catalyst percentage of 5%, and 6 hours of reaction. Means followed by same letters for each column did not differ statistically ( ).
