Abstract

The objective of this research was to study the production of ice milk supplemented with watermelon seeds embryonic leavespowder (WSELP). Mixes of ice milk containing 2%, 4% and 6% (WSELP) were prepared. Chemical composition of (WSELP) indicated higher total phenolics and radical scavenging activity (RSA). The highest total solids, fat content, protein content, ash content, caloric value, pH, viscosity and overrun were observed in the samples supplemented with (WSELP) and this increasing was proportional to the supplementation ratio. While ice milk samples containing (WSELP) were the lowest acidity (as lactic acid) scores. The ice milk samples prepared with 6% (WSELP) had the highest scores when judged sensory and the degrees of sensory acceptance matched the control. The total plate count and psychrotrophic bacteria count of all produced ice milk formulations were within the safe levels, and the moulds & yeasts were not detected.
