Production and Characterization of Tomato (Lycopersicon esculentum) Jam

Abstract

Aim: This study was carried out with the aim of developing and characterizing jam based on tomato fruit. Methodology: Four (04) formulations such as (A), 50% pulp, 50% sugar; (B), 59% pulp, 40% sugar, 0.5% citric acid and 0.5% pectin; (C), 69% pulp, 30% sugar, 0.5% citric acid, and 0.5% pectin; (D), 79% pulp, 20% sugar, 0.5% citric acid, and 0.5% pectin, were made and characterized in terms of pH by potentiometer, moisture by desiccation at 105o C, total soluble solids content (°Brix) by refractometry, titratable acidity by titration with 0.1N (NaOH), and sensory analysis by effective methods. The data was evaluated using Rstudio 4.2.1 software. Results: The results showed pH ranging from 4.84 to 5.09, soluble solids content from 39.79 to 66.42 ºBrix, titratable acidity in the range of 0.52 to 1.07%, and moisture content between 10.75 and 41.86%. The acceptance test showed that formulation A had the highest score of around 75%. Conclusion: Tomatoes proved to be an excellent and viable raw material for jam production.
