摘要：

The processing of peaches to produce fruit pulp generates solid and liquid wastes rich in phytochemicals, such as carotenoids; thus, the objective of this work was to study the use of this waste for carotenoid extraction based on a complete experimental design and using response surface methodology. The parameters studied were the amount of solvent (20-50mL), the number of extractions (1-5) and the extraction time (10-30min). The extracts were analysed by spectrophotometry and the optimised conditions by HPLC. The optimised results were four extractions of 10min using 38.5mL of ethanol, which presented a yield of 168.59gg(-1) DW of total carotenoids of which 67.55gg(-1) corresponds to -carotene, 86.75gg(-1) to cryptoxanthin, 12.08gg(-1) to zeaxanthin and 2.2gg(-1) to lutein, which representing 66% of extraction pigments relative to the total content of carotenoids present in the peach waste.
