Taste and aroma are very important features of cheese. Gen- erally, consumers make their choice of cheeses on the basis of flavor and other sensory characteristics (Awad, Ahmed & El Soda, 2007). The nisin incorporated cheese sample was preferred by the panelists over other samples for all the tested sensory attributes. With respect to color, there was no significant difference among samples (p40.05) and the nisin incorporated samples received significantly superior ratings for cheese flavor, odor, texture and overall acceptability compared to other samples (po0.05) (Ta- ble 1). At week 2, 3 and 4 nisin incorporated cheese samples were able to retain slightly higher moisture levels compared to other samples in the present study (Fig. 1A). This may be a reason to receive higher sensory acceptability for nisin incorporated cheese samples in this study, because higher moisture retention can avoid the development of tough and rubbery texture and improve the body, texture and functional properties of cheese (Low et al., 1998). The cheese flavor results from lipolysis and proteolysis by starter cultures and non-starter lactic acid bacteria and these microbes play a significant role in flavor, body and texture of finished chesses (Awad et al., 2007). However, higher acidity development and texture hardness may have been responsible in receiving lower sensory rating for LAB incorporated cheese samples in this study. Higher acidity could enhance the unpleasant taste/flavors such as higher saltiness in cheese
