CONCLUSIONS: Creaminess of samples was evaluated as a comparison between low-fat and

fat-free samples. This is a comparative measure between two samples, but

doesgivegoodindicationoftheeffectofformulationontheprotein:protein

network and resulting gel set. Such a test would be excellent both within the

Quality and Development environments, where product matching as well as

process control could be facilitated.

The modulus values are also considerably different where the higher values
