Title

PRODUCTION AND STORAGE OF SYNBIOTIC YOGURT

Pages

  19-28

Abstract

 Introduction: Yogurt is a fermented dairy product and due to its suitable sensory and functional properties, it is regarded as one of the most desirable dairy products. In recent years, suggestions have been made to consumers to use yogurts containing probiotics.Prebiotics are added to probiotic products to improve the sensory and technological properties of the food products. The yogurt products that contain both probiotic bacteria and prebiotic components are called symbiotic yogurt. The aim of this research work is to investigate the production and storage of symbiotic yogurt.Materials and Methods: In this study prebiotics including LACTULOSE, INULIN, and OLIGOFRUCTOSE as single, double and triple mixtures, and LACTOBACILLUS CASEI were used to produce SYNBIOTIC YOGURT. Sensory evaluations of the samples were carried out one day after production and the best sample was selected. In the next stage, the samples were compared with the control sample (probiotic yogurt without prebiotic) stored at 4oC for 21 days and their sensory properties and textural analysis (texture firmness) were carried out.Results: The results showed that the samples containing INULIN, LACTULOSEINULIN, and LACTULOSE OLIGOFRUCTOSE had the best sensory properteis. These samples and the control were refrigerated for 3 weeks at 4oC. The results suggested that the sample contained LACTULOSEINULIN had the best flavor and the control had the lowest score. The best score concerned with texture and texture firmness was the sample containing LACTULOSE- OLIGOFRUCTOSE while the control sample had the lowest score in term of firmness. There were not significant differences between the samples' color. The results suggested positive effect of prebiotic in probiotic yogurt.Conclusion: The study showed that prebiotics might be used for improving sensory and rheological properties of SYNBIOTIC YOGURT.
