Abstract : Whey protein (WP) is considered as a nutritional and functional ingredient, which is containing biologically active proteins. In this study WP added by two ratios 5% and10% to fruits jelly to enhance the protein content, evaluate physiochemical properties and probiotic effect of them. Jelly have been prepared consisted of pomegranate and guava lyophilized fruits, T1 pomegranate jelly, T2 pomegranate jelly with 5% WP, T3 pomegranate jelly with 10% WP, T4 guava jelly, T5 guava jelly with 5% WP and T6 guava jelly with 10% WP. Of all jelly, the highest moisture content was recorded in T1 (84.99 ± 0.07 %) and T4 (85.01 ± 0.08 %). Also, there were slight differences in the total soluble solid (TSS) content of the formulas, it ranged from 13.20 to 14.80 (ᵒBrix). The highest percent of total protein content were 0.21 ± 0.00% and 0.22 ± 0.02% in T3 and T6, respectively. The probiotic effect was conducted to test the effect of the product on beneficial bacteria found in the digestive system. Our results showed that fruits jelly have a positive effect on the growth rate of five strains of Lactobacillus. As well when the percent in WP increased the percent of growth rate was increased. The sensory and physicochemical analysis results showed that treated fruits jelly was acceptable and had good physicochemical attributes. Our findings indicated that treatment jelly have high nutritional value and an excellent potential for commercialization. Keywords: Jelly, Guava, Pomegranate, Probiotic, Whey, Protein.
