From Science Daily:

Adding calcium, Vitamin D and prebiotic dietary fibre to a beverage made of whey can have huge health benefits for those who drink it, team of Lithuanian scientists has discovered.

Writing in CyTA — Journal of Food, Algirdas Liutkevičius and colleagues describe how they created — and tested — two different versions of a whey-based beverage. While both drinks had Vitamin D and prebiotic dietary fibre added, one was enriched with calcium phosphate, the other with calcium lactate.

The aim of the study was to determine how much their chosen health-giving additives would affect the ‘physiochemical and sensory’ qualities of the drinks, as well as what effects drinking them would have on the health of volunteers.

First, trained tasters — and then members of the public — passed judgement on both drinks’ taste and appearance. While they found no appreciable difference in the visual appeal of the two formulas, the one made with calcium phosphate didn’t taste as nice after periods of storage.

With taste being so important, only the formulation with calcium lactate was put to 30 volunteers against a control drink for further testing. As the researchers explain, it is essential that any ‘functional beverage’ taste good: “Sometimes consumers agree to compromise sensory attributes for other perceived benefits, such as nutritional value or country of origin of the products. However, if the sensory attributes of the product do not meet consumers’ expectations, it is unlikely that such product will be used again. Nowadays, consumers can find very different…
