Physico chemical parameters of tomatoes

Abstract

An Investigation was undertaken to study physico-chemical parameters of tomatoes namely Pusa Ruby, Sadabahar, and Vaishali. The physico-chemical parameters included in the study were physical characteristics, PH, total soluble solids, moisture, reducing and total sugars, ascorbic acid, titrable acidity, lycopene and β-carotene content. The physical and chemical composition of three varieties of tomatoes were analysed by using suitable methods and techniques. The physical and chemical composition of three varieties differed significantly. It was observed that pusa ruby was deep red in colour, where as sadabahar was yellowish red in colour and vaishali was red in colour. Highest total soluble solids and sugar content was found in pusa ruby followed by vaishali where as least was observed in sadabahar. Among the varieties, the highest ascorbic acid and β-carotene content was observed in vaishali over other two varieties. The analysis of variance revealed a significant difference between the varieties at one percent level.
