Lipolysis in cheese: not too much – not too little

Propionibacteria are playing a key role in the lipolysis of Swiss-type cheeses. The statistical evaluation of datas collected from 30 commercial Emmental cheeses produced with two different propionibacteria cultures allowed to show, that lipolysis increases the intensity of the flavour. It was concluded that the weaker lipolysis in the cheeses with one of the two…

Fermentation of aspartate by propionibacteria increases the risk of second fermentation in Swiss type cheese

The statistical evaluation of datas collected from 30 commercial Emmental cheeses showed, that the deamination of aspartate to succinate by propionibacteria (aspartate metabolism) increases the risk of late fermentation in Swiss-type cheeses. It is not only the additional carbondioxide which is released during aspartate metabolism which reduces the potential time of storage, but it is…
