The aim of this research was to estimate sensory shelf life of "huacariz" and "cefop" mantecoso cheese, vacuum packaging: "cefop" and packaging to the atmospheric pressure: "huacariz"; brands marketed in Cajamarca, using accelerated shelf life testing. For this purpose, "huacariz" cheese was stored at 20, 28, 35 y 40 °C, while it was set at 20, 28, 35 °C storage for "cefop" cheese, performing acceptability sensory tests according to time storage with both 41 consumers constants. The results from sensory analysis were analyzed by software R for survival analysis statistics applied to sensory shelf life of foods. For this, Weibull distribution was applied and allowed to know shape (β) and scale (α) parameters, just being β value necessary to know the reliability of the raw data. The accelerated storage at temperatures close to 35 ºC yielded values of β < 2, for both cheeses, by t...
