| Abstract The aim of this research was compare methods for pigments extraction and color determination in different tomato for processing cultivars, and choose the most promising materials for the industry. The tomatoes for processing studied were of the IT761, H9992, H9553, AP533, Advance, N901, BRSena, U2006, HY26, HY37 and HY68 cultivars. The extraction yields of lycopene and β-carotene using acetone and the mixture of ethanol, acetone and hexane (10:10:20) were determined, and the parameters of color were determined by colorimetric and digitals image methods (Cielab and Hunterlab), besides other physicochemical characteristics. The mixture of solvents is more efficient in the extraction of lycopene and β-carotene than acetone on its own. The methods of... |

| Abstract In order to help the choice and recommendation of cultivars with the greater mechanical resistance of fruits, this research aimed to determine the mechanical resistance and biometric and physicochemical characteristics of tomato cultivars for industrial processing. Eleven processing tomato cultivar fruits cultivar were used (IT761, H9992, H9553, AP533, Advance, N901, BR-Sena, U2006, HY26, HY37 and HY68). Tomatoes firmness was influenced by several factors, including thickness, epidermal cell shape, and internal structures. In general terms, fruits more resistant to compression and puncture presented low longitudinal diameter (55-59 mm), cross-sectional diameter (42-45 mm), scar diameter (5.8-6.6 mm), pericarp thickness (5.9-7.7 mm), fresh weight... |
