Abstract
Pomegranate {Punica granatum L.) peel is a nutritive, antioxidant rich by-product, easily
available after production of pomegranate juice. The stutiy aimed to develop a fi"eeze- dried
pomegranate peel powder, identify its physico-chemical |iroperties, formulate tea and evaluate
the sensory attributes. Red pomegranate peels were freeze dried and ground to a fine powder.
The fi'eeze dried pomegranate peel powder and a randotnly selected commercial tea powder
were analysed for physico-chemical properties, functional properties, nutrient composition,
phenolic constituents, and sensory analysis. Samples weighing 2 grams, 3 grams and 5 grams
each of the pomegranate peel powder and commercial tea |iowder were added to 125 ml of
purified water and allowed to boil for the extraction of essence Ihe tea samples were subjected
for sensory evaluation by thirty semi trained panel members. I he moisture, ash, pH, titratable
acidity, water absorption capacity, oil absorpthm capacity and swelling power were found to
be higher in the pomegranate peel powder. Total poly|ihcnol conieni, tannins and free radical
scavenging ability were high in pomegranate peel |iowder. I’omegranate peel powder had a
better nutritional composition and phenol ic const i tuents comptired to the commercial tea powder
and exhibited good antioxidant properties.
