Probing the physicochemical characteristics of carrot sauce during storage

Globally, the prevalence of vit-A deficiency disorders i.e., xerophthalmia and nyctalopia is increasing especially in teenagers due to lifestyle shifts and undernutrition. This research was designed to develop carrot-supplemented tomato sauce to overcome vit-A deficiency and its related disorders. The carrot sauce was formulated with the addition of 50, 60, and 70% carrot pulp in tomato paste. The prepared sauce samples were tested for physical and biochemical changes in beta carotene (BC), lycopene, viscosity, pH, total soluble solids, titratable acidity, total plate count, and sensory parameters for 12 weeks. A non-significant effect of storage on BC, lycopene, and total soluble solids was observed. The total plate count, acidity, pH, and viscosity were influenced significantly. Sauce containing 60% of the carrot paste showed good sensory characteristics and 42.39 μg/g BC for the whole period of storage. It is concluded that carrot sauce can be used as tomato ketchup replacers to boost the overall quality of life by fighting against vit-A deficiency disorders.
