This work studies the influence of the operational conditions (temperature: 90–130C, activated clay
amount: 1–5 wt% and contact time: 20–60 min) on the bleaching process of degummed and neutralized
sardine oil. The bleached oils were evaluated for free fatty acids, peroxide value,p-anisidine value, totox,
oxidation stability (Rancimat) and color (CIELAB coordinates). Such measured variables were statistically
modeled by full factorial experimental design and response surface methodology. An individual optimum
value for totox of 21.38 (which minimizes oxidation products content) was obtained at 130C, 5 wt% of
clay amount and 60 min. Regarding the color quality, it was found a maximum value for hue-angle (89.19
at 99.2C, 5 wt% of clay and 56. 6 min) and a minimum value for chroma (81.76 at 109.4C, 5 wt% of clay
and 49.4 min). The conflicting effect of temperature and time on the location of the individual optima
motivated the generation of a Pareto front (set of non inferior solutions) employing the weighted-sum
multi-objective optimization technique.
