15 Jun 2017 --- Arla Foods Ingredients has launched a new whey protein solution that the companys says ensures that the protein bars it is used in stay soft for at least a year. Nearly half of US consumers (45%) purchased a high-protein bar in the past month, according to research. However, due to textural deterioration during shelf life – a common issue with high-protein snack bars – it’s likely that many of the bars had lost their soft and chewy texture by the time they were eaten.
