Abstract
Response surface methodology (RSM) was applied to study the optimum condition of mango seed kernel oil (MSKO) extraction with n-hexane. In the present paper, for the first time, we provide an optimal condition of MSKO extraction to obtain the maximum of yield, total phenolic content (TPC) and vitamin E. The experiment was conducted using central composite design (CCD) consisted of twenty experimental points including six replicates of center points to study the effect of three independent variables: temperature, time and amount of n-hexane on dependent variables. Data were analyzed using Design-Expert 10 software. The result showed that the optimum condition of MSKO extraction were 54.19 °C, 5.24 h and 224.23 mL of n-hexane. In this condition MSKO have yield of 7.03%, TPC of 67.77 mg GAE/g oil and vitamin E of 141.22 mg/L. These results suggest that MSKO has potential as raw materials of food products oil-based and as a natural antioxidant of functional food and for use in food processing.
Highlights
Mango, Mangifera indica, belongs to the family Anacardiaceae
The effects of X1, X2 and X3 on yield, total phenolic content (TPC) and vitamin E of mango seed kernel oil (MSKO) were studied during experimentation
The results showed that the yield, TPC and vitamin E of MSKO ranged from 5.16 to 7.08%, 31.81 to 67.52 mg GAE/g oil, and 100.25 to 140.27 mg/L, respectively
Summary
Mangifera indica, belongs to the family Anacardiaceae. It is a very popular fruit and often referred to as ‘king of fruits’ in the tropical world (Singh et al, 2002), but after consumed or used by the mango processing industry, mango seeds are generally only disposed of as waste Studies have disclosed that mango kernel is a potential source. F. Mas’ud et al.: OCL 2017, 24(5), D503 of wide range of bioactive compounds and antioxidants (Jafari et al, 2014). MSKO can be utilized for the preservation of fats and oils, improved oxidative stability of sunflower oil and tallow (Abdalla et al, 2007; Jafari et al, 2014)
