Abstract
In this research, a mixture of MPC, WPC, SMP, Soy milk, Margarine, Butter and water was used for production of UF-Feta cheese analogue.Variables were MPC (8%, 9%, 10%), WPC (0%, 1.5%, 3%), soy milk (5%, 10%, 15%) and margarine (0%, 5%, 10%). Chemical (total solids, protein, acidity) and sensory (color ...

In this research, a mixture of MPC, WPC, SMP, Soy milk, Margarine, Butter and water was used for production of UF-Feta cheese analogue.Variables were MPC (8%, 9%, 10%), WPC (0%, 1.5%, 3%), soy milk (5%, 10%, 15%) and margarine (0%, 5%, 10%). Chemical (total solids, protein, acidity) and sensory (color and appearance, aroma, texture, flavor, total acceptance) properties of Samples were analyzed 3 days post- manufacture.The central composite design (CCD) was employedand the results were analyzedusing response surface methodology (RSM). Coefficients of determination, R2, of fitted regression models for mentioned variables ranged between 84.94-99.99 and the lack-of-fit was not significant for all response at 95%. Hence, the models for all the response variables were highly adequate.The results showed that the optimum processing conditions for producing cheese with standard total solids and protein content and highest overall values for the sensory properties were: 9.13% MPC, 3% WPC, 15% soy milk and 7.65% margarine.

SMP was substituted by WPC in four levels for preparing reconstituted milk. Two ropy and one nonropy starter cultures was used for Doogh preparation. Yield stress, viscosity, consistency index and pseudoplastic behavior of Doogh increased by increasing WPC content. Results showed that WPC increased colloidal particles dimension and constructed a network which led to a decrease in Doogh phase separation (%32 at the highest level of WPC) during storage. Starter type had no effect on the Doogh stabilization. It does not have any effect on the studied physical properties in the presence of WPC, as well. Adding WPC to milk leads to improve of physical properties and stability of Doogh but using EPS producing starter cultures requires further studies in this field.

In this research, the effect of different levels of carrageenan gum (0.05– 0.2%) and whey protein concentrate (0.5 - 1.5%) on physical, chemical and sensory properties of low fat mozzarella cheese have been investigated. Use of these fat replacers cause significant differences (P ≤ 0.05) on chemical properties as increase in gum and WPC resulted moisture and protein content to increase but pH to decrease however carageenan was not affected. The physical properties of mozzarella cheese changed significantly (P ≤ 0.05) as increase in gum and WPC resulted meltability to increase although carrageenan had largest share of this effect. Increase of carrageenan resulted free oil formation to increase but increase of WPC was not significant. Length of stretch was not affected by carrageenan although increase of WPC decreased it. Carrageenan content did not effect on color, aroma and taste but score of texture and overall acceptance increased. WPC decreased score of color, aroma and taste but texture improved. The overall acceptance of treatments that have greatest amounts of carrageenan plus moderate amounts of WPC was higher than others. Finally the review of mixture experimental design results show that best low fat mozzarella cheese will produce with composition of 0.2% of carrageenan and up to 1% of WPC as fat replacers.
