Buffer Capacity Model

Buffer capacity modeling methods and software have been developed (Price et al., 2020). This technology was applied to estimate the effects of low acid salad dressing ingredients on dressing pH (Longtin et al., 2020). The models may be useful for estimating the effects of ingredients on pH changes in a variety of acid or acidified foods, as well as for food safety and product development purposes. Software is available for download at link below. The software was developed using Matlab programming environment (version 2019b) and requires the Matlab Optimzation toolbox.
