Abstract

Results obtained in determining Aw of Valdeteja cheese by Marcos et al (1981), Rüegg and Blanc (1983) and Fernández-Salguero et al (1986) equations and by the ormula Aw = 1,00937 - 0,00898 (NaC1) - 0,00274 (Ash - NaC1), developed in our laboratory, are checked. The later yields the best data (accuracy = ± 0,008). The one by Rüegg & Blanc gives good values too. Those of Fernández-Salguero et al were also very precises, but they must be slightly modified to apply then to this type of cheese.
