Consumers’ preferences and composition of Livanjski cheese in relation to its sensory characteristics

The aim of this study was to investigate consumers’ preferences of Livanjski cheese depending on the type of milk (cow’s milk or a mixture of sheep’s and cow’s milk) and the originality of production (farm or industrially produced). Also correlations between sensorial scores and the composition of Livanjski cheese were determined. Sixty day old Livanjski cheese samples produced on four family farms and under industrial conditions produced cheese were used for sensory evaluation. During the cheese sampling every producer was visited regularly (every two weeks) to evaluate the ripening conditions of the cheeses (temperature, relative air humidity and ventilation). Sensory evaluation was performed by 160 consumers and 6 experts. Cheese from farm 1 received the highest scores (P<0.05) in general and for every single attribute as well. The production of Livanjski cheese on farm 1 was distinct due to mixing sheep’s and cow’s milk (70:30 %) and due to good controlled ripening conditions (15-18 °C, relative air humidity 80-90 %, regular air ventilation). Sheep’s milk was an important factor for the higher scoring of Livanjski cheese. In opposite to the consumers’ preference, experts evaluated industrially produced Livanjski cheese with the highest score. Significantly high and negative correlations (P<0.05) between total solids of cheese and scores for taste and odour judged by experts were obtained. Moreover, significantly higher and negative correlations (P<0.05) between the total solids of cheese and all sensorial attributes were obtained by consumers. On the contrary, preserving factors i.e. higher salt content and acidity positively influenced the sensory attributes of Livanjski cheese.
