Effect of Natural Spices and Oleoresins on Lactobacillus plantarum in the Fermentation of Dry Sausage

ABSTRACT The effect of natural spices and oleoresins on the fermentation properties of three commercially available starter cultures of Lactobacillus plantarum has been investigated. In liquid medium it was shown that natural spices stimulated growth of the three bacteria and thus enhanced the cultures to ferment glucose and form more lactic acid. When similar oleoresin spices were supplied to the growing bacteria no effect was seen. It was also found that natural spices accelerated the fermentation process in the production of salami dry sausage while the oleoresins showed no effect.
