The influence of sweeteners in probiotic Petit Suisse cheese in concentrations equivalent to that of sucrose
As in the case of probiotic functional foods in recent years, demand has increased notably for light or diet foods with added sweeteners. However, little is known about the effect of different sweeteners on the microorganisms present. Thus, the objective of the current study was to establish the ideal sucrose concentration and equivalent concentrations of different sweeteners and to determine, by microbiological analyses, the influence of these compounds on the viability of the starter and probiotic cultures used in the production of strawberry-flavored Petit Suisse cheese during its shelf life. The ideal sucrose concentration was determined using the just-about-right (JAR) scale, and the equivalent concentrations of the sweeteners were subsequently determined by the magnitude estimation method. Microbiological analyses were also carried out to check the viability of the cultures during the product's shelf life. The results showed that the compounds Neotame (NutraSweet, Chicago, IL) and stevia presented, respectively, the greatest and least sweetening power of the sweeteners tested. None of the sweeteners used in this study exerted a negative effect on the viability of the starter or probiotic cultures, and thus we were able to obtain a probiotic, functional food with reduced calorie content.9695512552
Cheese. What is its contribution to the sodium intake of Brazilians?
The heightened intake of sodium from processed foods is of great public health concern throughout the world. This study evaluated the sodium contents of cheeses available in Brazil and the contribution of cheese to the daily intake of this micronutrient. The labels of 156 commercial samples of various types of Brazilian cheese (Minas, Prato, mozarella, and requeirdo cheese, as well as padrao cheese) were evaluated with respect to the reported sodium content. A high variability in the sodium contents of cheeses within each category was observed, although no significant difference was observed in the sodium content present in one serving (30 g) of cheese versus that present in 100 g of product (p > 0.05). With the exception of Minas cheese, more than 70% of the other cheeses examined in this study could be classified as high-sodium cheeses, with sodium contents exceeding 400 mg Na/100 g of product. These results suggest that cheese manufacturers need to reformulate their products and that public health authorities need to take additional measures to curb sodium intake from cheese consumption, including demand-specific labeling and implementing educational campaigns to inform the public about the dangers associated with high sodium intake.

Consumer perception of probiotic yogurt: Performance of check all that apply (CATA), projective mapping, sorting and intensity scale
The performance of check-all-that-apply (CATA), projective mapping, sorting and intensity scales was assessed for determining consumer perception of probiotic yogurts, two prototypes added with glucose oxidase, a potential oxygen scavenger and 04 commercial brands available in the Brazilian market. Each sensory methodology was tested by administrating the tests to 30 regular consumers of the product. Napping and CATA did not provide adequate discrimination of the samples while better results were noted for sorting and intensity scales, separating the yogurts containing glucose oxidase from the commercial probiotic yogurt. Sensory methodologies using consumer responses present potential options for the characterization of food matrices with multiple sensory sensations, such as probiotic yogurt. (C) 2013 Elsevier Ltd.

Probiotics in Goat Milk Products: Delivery Capacity and Ability to Improve Sensory Attributes
Dairy foods, particularly those of bovine origin, are the predominant vehicles for delivery of probiotic bacteria. Caprine (goat) milk also possesses potential for successful delivery of probiotics, and despite its less appealing flavor in some products, the use of goat milk as a probiotic carrier has rapidly increased over the last decade. This review reports on the diversity, applicability, and potential of using probiotics to enhance the sensory properties of goat milk and goat milk-based products. A brief conceptual introduction to probiotic microorganisms is followed by an account of the unique physicochemical, nutritive, and beneficial aspects of goat milk, emphasizing its advantages as a probiotic carrier. The sensory properties of probiotic-enriched goat milk products are also discussed. The maintenance of probiotic viability and desirable physicochemical characteristics in goat milk products over shelf life is possible. However, the unpleasant sensory features of some goat milk products remain a major disadvantage that hinder its wider utilization. Nevertheless, certain measures such as fortification with selected probiotic strains, inclusion of fruit pulps and popular flavor compounds, and production of commonly consumed tailor-made goat milk-based products have potential to overcome this limitation. In particular, certain probiotic bacteria release volatile compounds as a result of their metabolism, which are known to play a major role in the aroma profile and sensory aspects of the final products.</p
