Effect of addition of mosambi (Citrus limetta) peel powder on textural and sensory properties of papaya jam

This study evaluates the influence of addition of mosambi peel powder on jam prepared from papaya. Mosambi peel powder was first analyzed for its proximate composition and other properties. Mosambi peel had high amount of crude fiber (17.6%), besides water and oil-holding capacity (2.26 and 6.82 ml/g, respectively). Mosambi peel was treated with 5% of salt and/or sodium bicarbonate overnight to remove bitterness. Different levels of treated and untreated mosambi peel powder (2.5, 5, 7.5, 10, and 12.5%) were added to papaya jam and were evaluated for texture and sensory properties. The firmness and chewiness values of the jam added with mosambi peel powder increased significantly as compared to control, whereas adhesiveness and cohesiveness values decreased with increasing levels of mosambi peel powder. Sensory evaluation showed that jam prepared by addition of peel powder was acceptable up to 5% level of incorporation. However, jam made by the addition of untreated peel powder was not acceptable due to bitterness resulted from mosambi peel powder.
