The successful launch of multi-component products depends on a knowledge of the water activity of the individual components and their potential interactions. Rapid identification during product development can help to avoid problems after production. Computer programs offer a rapid and effective means of providing the necessary data and appropriate calculation techniques. Many component formulations can quickly be tried at the PC, modified and combined into the embryonic product prior to test baking. Additional features such as mould inhibitor levels and packaging can be examined. This paper will describe the use of a computer program to help with product development and ensure shelf stable products. It will be illustrated with practical examples of the approaches that can be taken. PC tools of this nature provide product developers with the means to innovate rapidly and effectively.
