摘要: Sardine (Sardinops sagax caerulea) oil was refined and the fatty acid composition as well physical chemical quality variables were monitored. The refining of crude sardine carried out in three stages: alkali-refining, clay-bleaching, steam-deodorizing. Results show that process significantly improved (p < 0.05) oil, by decreasing its peroxide value (from 10.05 to 0.81 meq/kg), p-anisidine 3.67 1.63 mmol/kg), free acids content 0.21 0.052% oleic acid). oxidative stability increased from 10.39 17.55 h (using Rancimat at 60°C, 7 L/h air flow). These values are within acceptable standards for edible fish oils. No significant differences observed composition. notable improvement properties produced high terms color (golden yellow) odor (odorless).
