Sherbet and Sorbet mixes were prepared to contain 9% fresh mango pulp, per se, 1% cooked pumpkin (CP). The water quantity required for both was replaced with ultrafiltrated milk permeate (UFMP) at the level of 25, 50 or 75%. The obtained results indicated that, separately, CP composed of higher moisture and total nitrogen, total phenolics (TP) as well as radical scavenging activity (RSA) values and lower total flavonoids (TF), carbohydrates contents than mango pulp. In both, Sherbet and Sorbet mixes, water substitution with UFMP was associated with increase in total solids, total and reducing sugars as well as ash contents. Neither acidity %, nor pH values were significantly affected by the partial substitution of water with UFMP in Sherbet mix, although the acidity % of Sorbet mix was significantly increased by UFMP addition. Freezing point of Sherbet or Sorbet mixes was gradually minimized by increasing the substitution level, although the flow behavior index was not influenced in Sherbet but increased in Sorbet mixes. The proportional increment of UFMP level in mix was associated with gradually considerable increase in its consistency coefficient, apparent as well as dynamic viscosities, TP and RSA values of both Sorbet and Sherbet mixes. UFMP led to increase in the specific gravity of mixes before and after freezing as well as elevated the overrun and strengthened the melting resistance of the final product. Furthermore, the frozen dessert of 75% UFMP, whether being Sherbet or Sorbet gained the highest panelists scores for all sensory attributes. It could be concluded that, it could successfully produce a product that meets the intended health purposes based on the substitution of 10% of mango pulp with pumpkin solids of many impressive health benefits as well as the utilization of ultrafiltration milk permeate as a source of the essential electrolytes instead of 75% of required water en route to innovate frozen desserts such as Sherbet and Sorbet
