Abstract

Tomato (Solanum lycopersicum) is one of the potential horticultural products, healthy and has a promising market prospect. Tomato contain arytenoids element which called lycopene. Lycopene was one of yellow dark to red dark pigment included in arytenoids groups that responsible to make red color in tomato. Arytenoids compounds is well known as compounds which have high antioxidant power, this compound is able to fight free radicals caused by pollution and UV radiation. Antioxidant separation by extraction method of tomato fruit in liquid phase using the mixture of ethanol and hexane. The purpose of this study was to obtain liquid extract antioxidant-rich from tomatoes (lycopene) as an intermediate product that has many benefits to be used as industrial raw materials. In this study, using the variable ratio of F/s = ( 1/1,1/2, 1/3, 1/4, 1/5 ), extraction temperature T = ( 45, 55, 60, 65, 75 )0C, and extraction time t = ( 60 ) minutes. Next determinitions the concentration of antioxidants were calculated using the UV-VIS spectrophotometer analysis. From the results of this study indicate that the optimum condition of lycopene extraction operation using solvent mixture of n- hexane and ethanol is the ratio of F/s, 1:4 at the operating temperature of 650C and 60 minutes for the extraction time variable. In this condition, lycopene extracted by 6.049 mg/100gram or equal to 47.2%.
