The influence of the texture and color of goat’s salad cheese on the emotional reactions of consumers compared to cow’s milk cheese and Feta cheese
AbstractIn this study, the sensory and mechanical aspects of the texture of goat’s milk salad cheese were correlated with the emotional profiles of consumers. Using descriptive sensory analysis and instrumental assessment, the texture profile of goat’s milk salad cheese was compared to cow’s milk salad cheese and Feta cheese. Texture measurements confirmed that goat’s cheese compared to cow’s cheese had more softness and less hardness, and Feta cheese had the highest whiteness index compared to the other cheeses. Goat’s milk salad cheese was much less acceptable to consumers compared to cow’s milk cheese and Feta cheese. Consumers also indicated that the hardness of goat’s cheese was lower than that of cow’s cheese and Feta cheese. A reduction in “stickiness” in comparison with cow’s cheese was also reported; however, it was much higher than that for Feta cheese. The “fracturability” and “graininess” of goat’s cheese was similar to cow’s cheese. Emotional profile analysis showed that goat’s cheese evokes mainly negative emotions. Consumers indicated only one positive emotion in the case of this cheese, which was “healthy”. The most frequently mentioned emotions after the consumption of goat’s cheese were “upset”, “disgusted” and “worried”. Many consumers also indicated “disappointed” and “angry”, which did not occur after the consumption of cow’s cheese. This research shows how important it is to combine several analyses and techniques when evaluating dairy products, including salad cheeses. It is also important that consumer research is enriched by emotional profiling. Graphical abstract
Analysis of Water Activity and Gloss of Stored Goat Cheeses According to Consumer Preferences and Tastes
Packaging is an integral part of every food product, especially cheese. An important goal is to protect the product from spoiling and drying out. Two types of cheese were tested: soft goat’s cheese and hard goat’s cheese. They were evaluated for gloss, water activity, and colour. The aim of the research was to assess changes in the water activity of goat cheese in correlation with changes in gloss and color during storage in various forms of packaging, depending on consumer habits. The research problem was based on consumer observations regarding the repackaging of dairy products, including goat’s cheese. Consumers have reported such a problem in previous studies. The question was asked: will it be necessary in the future to indicate to the consumer the appropriate form of repackaging for a given goat’s cheese? It was shown that the best packaging for storing open feta-type goat salad cheeses was aluminum foil and hard goat cheeses in the producer’s packaging. The method of storage only affects the change in gloss in the case of goat salad cheese and parameter a* hard cheese. At the same time, the need was noted to develop appropriate packaging that would serve to protect the product from spoilage and would not pose a threat to the natural environment after being thrown into the trash. Wrapping soft goat cheeses in cellulose fiber paper reduced water activity by 5% after 14 days of storage but did not encourage re-consumption. The key task for future research is, therefore, to carry out regular consumer surveys. Therefore, it is necessary to choose (develop) a packaging that would preserve the original quality of the cheeses when stored in these conditions.
