Calcium Lactate Fortification of Reduced Fat Yogurt and Fortification of "Simulated Yogurt Gel" with Partially Hydrolyzed Whey Protein
<p>There has been great demand of calcium fortified dairy products as they can serve as ideal vehicle for carrying extra calcium to fulfill the nutritional needs but there is need to generate information on the effect of fortification of calcium on the physical properties of these products. In the …
