Essential Oil Yield

Pomelo leaves oil has many applications regarding hair nourishment and stimulation. Recently, new methods of extracting essential oil used have been increasingly developed to replace traditional methods. In this research, maximization of essential oils yield from Citrus grandis was studied by the combination of microwave assisted hydro-distillation (MAHD) and response surface methodology (RSM). We found that the maximum essential oil yield was 0.3197 % with 91.3 % desirability corresponding to factors such as material and water ratiosof 3.04:1, extraction time at 62.76 min and microwave power of 482.17 W. ANOVA analysis for quadratic model also gives favourable outcome including the high determination coefficient (R2 = 0.9443), significant F-value and p-value of coefficients. All these values indicate that this model is significant between experimental and predicted variables.

Main Factor

Abstract—Main problem in the processing of Dioscorea alata’s tuber into flour is the changing of colour.  One factor in color changing is attributed to antocyanin reaction in the tuber.  Several methods can be applied to minimise the browning and hence maintain the natural colour preferred by the consumers.  This research was conducted to obtain the combination of age of harvest, blanching temperature and blanching length which produce the highest content of antocyanin in Dioscorea alata’s flour. The responses measured was anthocyanin content. The result showed that age of harvest was the main factor for anthocyanin content of Dioscorea alata flour. The optimum anthocyanin content is predicted to be achieved by using tuber harvested at 9.6 months, temperature of blanching 86.12oC and blanching time for 0.56 menit.
