Reformulating Minas Frescal cheese using consumers' perceptions: Insights from intensity scales and check-all-that-apply questionnaires

Abstract

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.

Probiotics in Goat Milk Products: Delivery Capacity and Ability to Improve Sensory Attributes

“…The utilization of consumers to obtain analytical information about products has increased, as has the number of rapid methods that can be performed by naïve consumers or semi‐trained panelists (Rogers, ). These developments further allow industry stakeholders to recognize the sensory features of ideal products and characteristics that warrant reformulation (Oliveira et al., ). Rapid characterization methods such as Check‐all‐that‐apply (CATA), Projective Mapping, and Pivot Profiles can be useful as these tests provide a total assessment of products and take all sensory traits into account (Cruz et al., ; Esmerino et al., ; Valentin, Chollet, Lelièvre, & Abdi, ).…”

Physicochemical and sensory properties of goat cheeses and their fatty acid profile in relation to the geographic region of production

“…Using consumer opinions to obtain a sensory description of the products and hedonic judgements allows manufacturers to identify the sensory characteristics of the ideal product (Oliveira et al . ; Torres et al . ).…”

Cheese sauces: Characteristics of ingredients, manufacturing methods, microbiological and sensory aspects

“…To perform this task, it is recommended to use the so‐called intensity scales and the method that would describe and accurately review cheese sauces in organoleptic and visual aspects is check‐all‐that‐apply (CATA). Questions included in the survey are one of the quickest ways that have been introduced in sensory analysis, it is easy to implement, and not annoying to consumers (Oliveira et al, ; Torres et al, ). In the CATA questionnaire, consumers are asked to choose from a 9‐point rating scale the point that describes in the best way the individual aspects of the tested product.…”
