| Abstract | ||
| The study includes extraction of oil from wheat germ using organic solvent ,chloroform–methanol and water(1:1:0.5) and study the physicochemical properties of refined oil . Wheat germ oil storage at 4°C for 35 days showed slight effects on physicochemical properties of refined oil. The results were as follows : viscosity, acid value, peroxide value and saponification number increase from 29.57cent pois to29.59 cent pois,0.22 mg/g to 0.26 mg/g, 0.89 millequiv./ Kg oil to 0.91 millequiv./Kg oil and 179.52 mg/g to 179.56 mg/g oil respectively. While color intensity, Specific gravity and iodine value decrease from, 0.9288 to 0.9286, 126 to 125 mg/100g oil respectively. Wheat germ oil storage at 25-30 °C for 35 days showed more effects on physicochemical properties of refined oil. The results were as follows : viscosity, acid value, peroxide value and saponification number were raised from 29.57cent pois to30.55 cent pois,0.22 mg/g to3 mg/g, 0.89 millequiv./ Kg oil to 4.69 millequiv./ Kg oil and 179.52mg/g to 195 mg/g oil respectively. While color intensity, Specific gravity and iodine value decrease from0.098 to 0.085, 0.9288ml/g to 0.9012, 126 to 115 mg/100g oil respectively. | ||
