Introduction
Consumers are more aware of, and knowledgeable about, their health than ever before.
This
increased focus has led to people following a variety of different
diets, with a wide range of dietary specifications, putting pressure on
manufacturers to develop a portfolio of foods and drinks to meet
individual needs. In many cases, this involves reformulating an existing
product to have more of a particular ingredient, such as higher protein
content, or less of another, including salt, fat and sugar.
