Abstract
Detection of Adulteration in Tomato Ketchup prepared with commonly used
adulterants are pumpkin, ash gourd. sweet potatoes, carrot, papaya and apple
pomace was carried out using histological characteristics and staining techniques.
Camera Lucida drawings of the samples of tomato ketchup containing the various
adulterants showed thot adulterants like pumpkin, ,sweet potatoes ond carrots could
be detected on the basis of their cell structures which are distinctly different than
those of tomatoes. Staining, wlth iodine further confirmed the presence of these
adulterants. Presence of apple pulp could be detected by staining with methylene
blue. Detection of ash gourd and papaya was, however, not possible with these
techniques.
