Sensory analysis for stuffed cheese with Penicillium nalgiovense superficial growth

Abstract

Sensory analysis for stuffed cheese with Penicillium nalgiovense superficial growth using a descriptive analysis was performed. Cheeses were manufactured in a pilot plant. Penicillium nalgiovense was superficially inoculated and the cheeses were ripened at 12 °C and 90% relative humidity until packaged using a microperforated polyethylene film on day 14. The ripening process continued at either 5 °C or 12 °C for 21 days. Results showed that P. nalgiovense not only confers the external desirable appearance but also has a protective effect against dehydration process. Inoculated cheeses showed descriptors of odour and flavour associated with moulds. Ammonia notes were perceived only for inoculated cheeses on day 35 being more pronounced at 12 °C than 5 °C. The high fat content of the cheeses and the transparent and microperforated packaging might affect the oxidative stability of cheeses at the end of the ripening.
