Abstract

(DMME) for phenolic compounds extraction from peanut (Arachishypogeae L.) shell was determined using a statistical full factorial design of experiment (DOE) method. The influence of ethanol concentration (%), solvent to solid ratio (v/w), and irradiation time (s) on total phenolic content (TPC) of peanut shell extracts was investigated. The significance of each variable and their interaction effects were also evaluated in response to TPC. Results showed that within the range of variables studied TPC of peanut shell extracts increased with the increase in ethanol concentration and irradiation time. The TPC of extracts ranged from 0.6318 to 7.7901 g GAE/100 g extract. Extract with the highest TPC value was obtained at DMME condition as follows: ethanol concentration of 96%, irradiation time of 150 second, and solvent to solid ratio of 10:1.The DOE result showed that TPC of peanut shell extracts were significantly affected by irradiation time (p<0.0001), followed by ethanol concentration and solvent to solid ratio. The relationship between the controlled variables and response may be predicted by the equation obtained. Under the optimised conditions, the experimental TPC value was reasonably close to the DOE predicted value.
