We evaluated the performance of check-all-that-apply (CATA) questions and intensity scales to describe Minas Frescal cheese and its reformulation based on consumers' perceptions. Ten commercial samples with different formulations (full-fat, low-fat, or low-lactose) were evaluated by 200 consumers divided equally into 2 groups: 1 evaluated samples and described their ideal cheese using intensity scales and 1 did the same using CATA questions. Both methodologies provided similar information about the sensory characteristics of the Minas Frescal cheeses, the description of the ideal product, and directions for product reformulation. The ideal Minas Frescal cheese was characterized by high moisture, intense white color, homogeneous mass, typical Minas Frescal cheese aroma and flavor, softness, and juiciness. For the intensity scales, the recommendation was to increase the typical aroma and flavor, salty taste, and juiciness, and to decrease the bitter flavor; for the CATA questions, only increasing the typical Minas Frescal cheese flavor was important for all classes of cheeses. Even for a heterogeneous product with no defined manufacturing protocol, both methodologies presented satisfactory results that should be considered for use by cheese producers and the dairy industry.
我们评估了多选式(CATA)问题和强度量表在基于消费者认知描述米纳斯弗雷斯科奶酪及其重新配方方面的性能。200名消费者对10个不同配方(全脂、低脂或低乳糖)的商业样品进行了评估,消费者平均分为两组:一组使用强度量表评估样品并描述他们理想的奶酪,另一组使用CATA问题进行同样的操作。两种方法都提供了关于米纳斯弗雷斯科奶酪感官特性、理想产品描述以及产品重新配方方向的相似信息。理想的米纳斯弗雷斯科奶酪具有高水分、浓郁的白色、质地均匀、典型的米纳斯弗雷斯科奶酪香气和风味、柔软多汁的特点。对于强度量表,建议增加典型香气和风味、咸味以及多汁性,并减少苦味;对于CATA问题,仅增加典型的米纳斯弗雷斯科奶酪风味对所有类别奶酪都很重要。即使对于没有明确生产规程的异质产品,这两种方法都给出了令人满意的结果,奶酪生产商和乳制品行业在使用时应予以考虑。
