Response surface methodology (RSM) was applied to optimize the oven drying conditions for lycopene
content (Y1) and lipophilic antioxidant capacity (Y2) in decanter, a by-product of the pink guava puree
industry. Two-factor central composite design was employed to determine the effects of two independent
variables, namely temperature (X1: 50–80 C) and drying time (X2: 4–6 h). Lycopene content and
lipophilic antioxidant capacity were measured using high-performance liquid chromatography (HPLC)
and the ABTS radicals scavenging assay, respectively. A b-carotene bleaching assay was also applied to
measure the antioxidant activity. Response surface plots showed that an increase in temperature and
time significantly reduced the response variables. The optimum oven conditions for drying of decanter
with minimum lycopene degradation were 43.8 C for 6.4 h, with a predicted lycopene content of 14 mg/
100 g and antioxidant capacity of 21 mmol LE/100 g. To validate the optimized model, the experimental
values were compared with the predicted values to check the adequacy of the model. The experimental
values were found to be in agreement with those predicted, indicating the suitability of the model for
optimizing the oven drying conditions for decanter.
