Abstract

ABSTRACT: The aim of this study was to evaluate the effect of the inclusion of microbial biomass on the oxidative rancidity of tilapia rations stored for 12 months. Treatments included a control diet and diets supplemented with either 0.01% vitamin E, 0.25 and 0.5% of Saccharomyces cerevisiae and 0.25 and 0.5% of Spirulina platensis. Experimental diets were stored in the dark inside plastic bags at room temperature (25 °C) for 12 months. The oxidative rancidity was measured as thiobarbituric acid reactive substances (TBARS). It was concluded that the inclusions of Spirulina platensis at 0.25% (1.734 ± 0.206) and 0.5% (1.629 ± 0.181) and Saccharomyces cerevisiae at 0.5% (1.459 ± 0.305) minimized the oxidative rancidity in comparation to control diet (2.843 ± 0.109) of Nile tilapia until 12 months of storage.
