Fresh cut leek was mixed with salt for 0.5 (IM) and 5 (LM)min or remained untreated (control) and stored alone or mixed with minced meat and seasonings, cased and stored at 15°C for 7days. The fresh cut leek and sausage metabolics and sausage microbiological and physicochemical traits were measured during storage. Sausages with LM leek had significantly higher counts of lactic acid bacteria, faster rates of pH drop and dehydration and increased red color compared with the other treatments. Sausage to fresh cut leek peaks of CO₂ or C₂H₄ production was 5 or 2 fold higher in LM than the other treatments indicating that the sausage flora was the source of both. The use of salt-stressed fresh cut leek before manufacture of sausages enhances microbial activity as well as its stability and shortens the necessary storage time needed for the development of the quality characteristics of Greek traditional sausages.
