Enhancement of lycopene extraction from tomato peels by enzymatic treatment
نویسنده
چکیده
Four food-grade enzyme preparations (Citrozym CEO and Ultra L, Peclyve EP and LI) with pectinolytic, cellulolytic and hemicellulolytic activities were investigated to assess their suitability for improving lycopene recovery from tomato peels. After a preliminary screening, the influence of solvent type and enzyme incubation time on the extraction efficiency was studied. Under the best conditions (1-h enzyme incubation followed by a 3-h solvent extraction at 40 °C) up to 440 mg of lycopene per 100 g of dry tomato peels were obtained. Experiments on the peel fraction of tomato processing waste confirmed the significant increase in yields resulting from the use of enzymes. Overall, lycopene recovery from the enzymatically treated material was between 70 and 98%, while yields from the untreated peels were in the range of 3–40%.

Optimization of pectinase-assisted and tri-solvent-mediated extraction and recovery of lycopene from waste tomato peels
In the present work, optimization of pectinase-assisted and tri-solvent-mediated extraction of lycopene from waste tomato peels was carried out. The optimized parameters for enzymatic pre-treatment were 2% pectinase concentration, pH 5.5, 4-h incubation, 45 °C and 150 rpm. Maximum recovery of lycopene from tomato peels using optimized tri-solvent extraction was achieved at 45 °C, 120-min incuba...
متن کاملLycopene recovery from tomato peel under mild conditions assisted by enzymatic pre-treatment and non-ionic surfactants.
The tomato processing industry generates large quantities of tomato peel residues, usually creating environmental problems. These residues are a significant source of lycopene, thus providing an attractive alternative for profitable handling of these otherwise problematic by-products. The enzymatic pretreatment of these residues for lycopene recovery has already been employed, although the use ...

A simple mixture process design based on the comparison of both quadratic and special cubic models and involving three mixture components (hexane/acetone/ethanol) as a solution for extracting lycopene from raw tomato, tomato sauce, and tomato paste was used to confirm the hypothesis that lycopene extraction rates are a function of the solvent used during the extraction process. Conventional cri...
