How buyer-focused projective techniques can help to gain insights into consumer perceptions about different types of eggs.

This study aimed to analyze the consumer perception (n = 840) about different types of eggs using Product Personality Profiling and Shopping List tasks. White egg, brown egg, organic egg, free-range egg, and eggs enriched with omega 3 and vitamins were evaluated. The consumers associated the white egg with unhealthy, sedentary, and overweight individuals in the Product Personality Profiling task and people that are not concerned with health in the Shopping List task. The brown egg was associated with a person who does physical activity and has a healthy diet in the Product Personality Profiling task. The omega 3 egg was associated with a person concerned with health in the Shopping List task, which does physical exercises and follows a healthy diet in the Product Personality Profiling task. The vitamin-enriched egg was associated with people with health disorders in the Shopping List task and following a vegetarian/vegan diet in the Product Personality Profiling task. The free-range egg was associated with a man with a rugged personality, a healthy diet, and animal welfare concern. Finally, the organic egg was associated with a person concerned with animal welfare and a vegetarian/vegan diet. Shopping list and Product Personality Profiling projective techniques proved to be useful tools for understanding consumer perceptions and beliefs about eggs, providing similar or complementary results. The Shopping List was more appropriate in eliciting egg buyers' profile, while the Product Personality Profile shows the "target buyer".

Q Methodology: An interesting strategy for concept profile and sensory description of low sodium salted meat.

The conceptual representation and sensory profiling of low sodium salted meat containing different flavor enhancers (n = 9) were investigated using the Q methodology. Seventy consumers performed a Q-sorting task having in mind the health concept, using a hedonic test and sensory description of the samples. Regular sodium salted meats were associated to the health concept and were characterized by as too much salt, fatty, salty taste, strange taste, and high blood pressure, while the low-sodium samples were associated with good appearance, metallic taste, and healthy. The Health questionnaire showed it is a valorization of food with improved sensory characteristics in addition and the importance of physical and emotional health. Our findings suggested the Q methodology can be an interesting tool for meat processors, together with the traditional sensory test with consumers, to obtain more consistent and complementary information about meat products.

Partial substitution of NaCl by KCl and addition of flavor enhancers on probiotic Prato cheese: A study covering manufacturing, ripening and storage time.

Cheese is a suitable matrix to deliver probiotic strains but it contains a high amount of sodium. The effect of partial substitution of NaCl by KCl and the addition of flavor enhancers (l-arginine, yeast and oregano extract) on probiotic Prato cheese was investigated after 1, 30, and 60 d of refrigerated storage (immediately after manufacturing, and during ripening and storage). Microbiological (lactic acid bacteria and probiotic Lactobacillus casei 01 counts and survival under gastrointestinal conditions), physicochemical (pH, proteolysis, fatty acids), bioactivity (antioxidant effect and angiotensin I-converting enzyme inhibitory activity), rheological, and water mobility by means of time domain low-field nuclear magnetic resonance were investigated. Significant changes in probiotic survival were observed; however, the sodium reduction and the addition of flavor enhancers did not constitute an obstacle to L. casei 01 (>108 CFU/g) during storage. Slight changes were observed in proteolysis, bioactivity, water mobility, texture profile, and fatty acids of the cheeses as a function of the flavor enhancer added. The sodium reduction and the supplementation of Prato cheese with probiotic cultures may be an effective alternative to the production of a potentially functional cheese.
