The specific cured meat odour and taste stimulus thresholds in pork containing different quantities of sodium nitrite were determined in relation to the residual nitrite level and relative contents of nitrosylpigments in meat. It was stated, that the specific odour and taste detection thresholds were equal to 10 and below 10 mg NaNO2/kg of meat, respectively, and the specific odour and taste recognition thresholds were equal to 26 and 21 mg NaNO2/kg of meat, respectively. The detection and recognition thresholds corresponded to 2.4 and 8.5 mg of residual nitrite in meat, respectively. In all the cases the relative contents of nitrosylpigments were above 50%. Taking into account the maintening of specific cured meat odour and taste, the dose of sodium nitrite in pork curing may be lowered to 30 mg/kg.

The present research evaluated the effect of selected strains with anti- properties on the characteristics of traditional soft-ripened cheeses produced in two different seasons. Physicochemical, microbiological, texture, volatile compound, and sensory evaluations were performed on the cheeses after 60 days of ripening. The inoculation with protective cultures of selected LAB did not negatively affect the physicochemical parameters of the cheeses.

Traditional cereal vinegars are fermented by microorganisms that are spontaneously enriched, leading to uncertainty in regulating the fermentation process and flavor. The objective of this study was to elucidate the impact of the predominant microorganisms, provenly and , on the solid-state fermentation (SSF) and flavor profile of cereal vinegar by several bioaugmentation strategies. The results indicated that the sequential bioaugmentation of predominant microorganisms improved the utilization of raw material and most key flavor compounds.
