Sensory characterization of commercial cream cheese by the consumer using check‐all‐that‐apply questions

Aroma-sensory properties of Gouda cheeses based on young Chinese consumers' preferences

The objective of this study was to examine the aroma profiles of 12 Gouda cheeses sold in China and to determine which aromas were preferred by young Chinese consumers (n = 110). The consumers selected 11 descriptors of the aromas of the Gouda cheeses in a check-all-that-apply questionnaire. These 11 descriptors were used by a panel of experts for sensory analysis to perform a quantitative descriptive analysis of the cheeses. A principal component analysis of the data from the quantitative descriptive analysis revealed that the characteristic aromas of young Gouda cheeses, medium-aged Gouda cheeses, and aged Gouda cheeses were "milky" and "whey"; "creamy" and "sour"; and "rancid" and "nutty," respectively. The results of a penalty analysis combined with the check-all-that-apply results and the preference scores showed that the 3 groups of young Chinese consumers (those who often ate cheese, occasionally ate cheese, and never ate cheese) preferred the Gouda cheeses with "milky" or "creamy" aromas and did not enjoy those with "sour" or "rancid" aromas. Occasional cheese eaters comprised the majority of the young Chinese consumers, and they were more tolerant of the Gouda cheeses with "whey" and "sulfury" aromas than those who often or never ate cheese. In addition, we identified a positive correlation between the consumers' preferences for the aromas of the Gouda cheeses and their willingness to pay for them. Overall, the results of this study should help promote the development of Gouda cheeses and associated products that meet the preferences of young Chinese consumers.

Plant-Based Alternatives Need Not Be Inferior: Findings from a Sensory and Consumer Research Case Study with Cream Cheese

Reliance on animal foods must be reduced to improve planetary and human well-being. This research studied plant-based cheese alternatives (PBCA) relative to dairy cheese in a consumer taste test with 157 consumers in New Zealand. A case study approach used cream cheese (commercially available) as the focal product category (2 PBCA, 2 dairy) and implemented a multi-response paradigm (hedonic, sensory, emotional, conceptual, situational). "Beyond liking" insights were established, including drivers of liking (sensory, non-sensory) and sensory drivers of non-sensory product associations. Two consumer segments were identified, of which the largest (n = 111) liked PBCA and dairy samples equally (6.5-6.7 of 9). In this PBCA Likers cluster, the key sensory drivers of liking were 'creamy/smooth mouthfeel', 'dissolves quickly in mouth', and 'sweet', while a significant penalty was associated with 'mild/bland flavour'. The non-sensory data contributed additional consumer insights, including the four samples being perceived as differently appropriate for 9 of 12 use situations, with PBCA being regarded as less appropriate. In the limited confines of this case on cream cheese, the findings show that PBCA need not be inferior to their dairy counterparts despite a general narrative to the contrary. Of note, the results were obtained among participants who were open to eating a more PB diet but were not vegetarian or vegan.

Consumer Perception and Liking of Parmigiano Reggiano Protected Designation of Origin (PDO) Cheese Produced with Milk from Cows Fed Fresh Forage vs. Dry Hay

This study aimed to investigate consumer sensory profiles and liking of Parmigiano Reggiano PDO cheese produced with milk from cows reared indoors and fed with different forage sources, i.e., dry hay and fresh forage. Two cheese samples were tested by 119 Italian subjects, following a protocol that included a Check-All-That-Apply method to assess the sensory profile, a Just-About-Right scale to evaluate the adequacy of attributes, and questions on liking (9-point hedonic scale). A questionnaire related to personal information and consumption habits was also submitted. The color of the two samples, based on image analysis, was different: the sample produced with milk from the dairy cows fed fresh forage had a higher intensity of yellow than the other; they were also described differently (p ≤ 0.05) by participants in the consumer test. Indeed, Parmigiano Reggiano produced with milk from the cows that were fed dry hay was mainly characterized by a "fresh milk" and "solubility", while the sample produced with milk from cows fed fresh forage was described as "yellow", "seasoned", "pungent", and with a "cheese crust" flavor. Even if no significant differences were observed between the two samples in terms of liking (p ≤ 0.05), the attribute "graininess" showed a great impact on liking ratings together with "yellow" (p ≤ 0.05), apparently corresponding to a specific expectation regarding the intensity of these attributes. Data were also analyzed according to the gender of consumers, highlighting that for women, the adequacy of "fresh milk", "sweet", and "graininess" greatly impacted liking for the cheese from cows fed dry hay.

Consumer Acceptance Studies of Margarine to Guide Product Development in the Food Industry

Margarine exhibits significant variations in composition, allowing it to cater to diverse consumer segments. This study aimed to characterize the physical and sensory attributes of margarine samples available in the Brazilian market. Twelve commercial samples from six different brands, encompassing 30% to 80% of lipid contents, were subjected to instrumental texture analysis and affective assessment. A total of 112 consumers participated in acceptance tests and Check-All-That-Apply (CATA) evaluations, while another group of 62 subjects performed Projective Mapping. Samples with lipid percentages exceeding 70% achieved the highest average acceptance scores for taste and overall impression. The brand with the lowest lipid content (30%) exhibited a stronger association with negative attributes, including rancid flavor and aroma, bitterness, and metallic flavor, resulting in lower average scores for aroma, flavor, texture, and overall impression. However, these scores were not statistically different from samples with 50% and 60% lipid content. Reducing lipid levels in fat-based products such as margarine poses a challenge to food manufacturers, as consumers generally perceive higher lipid percentages as indicative of superior flavor quality.

A low-fat synbiotic cream cheese containing herbal gums, Bifidobacterium adolescentis and Lactobacillus rhamnosus: Physicochemical, rheological, sensory, and microstructural characterization during storage

This study aimed to use natural herbal gums, as fat replacers, for preparing a low-fat synbiotic cream cheese; for this purpose, the effects of Lepidium perfoliatum seed gum (LPSG) (1% w/w) and flaxseed gum (FG) (1% w/w) on physicochemical, rheological, organoleptic, and microstructural properties of low-fat cream cheese containing B. adolescentis and L. rhamnosus were analyzed over a 45-day storage period. The results indicated that adding LPSG and FG had no significant effects on acidity and pH (p > .05). The results also showed that full-fat (FF) cheese samples had the highest textural (hardness (1.099-0.88), cohesiveness (0.72-0.67), springiness (1.95-1.64), adhesiveness (1.01-0.69), and spreadability (1.53-1.17)), viscosity and sensory scores (color (4.22-4.18), odor (4.13-4.09), taste (4.19-3.89), texture (4.08-3.81), and overall acceptability (4.01-3.72)) during 45-day storage. Based on the probiotic count test, only the treated samples with LPSG + FG had a probiotic count in the standard range (6.23 cfu/g) at the end of the storage time. The outcomes of the present study indicated that the incorporation of LPSG and FG into the formulation of low-fat synbiotic cream cheese could be an effective strategy to overcome the problems associated with fat reduction.

Hybrid Spreadable Cheese Analogues with Faba Bean and Mealworm (Tenebrio molitor) Flours: Optimisation Using Desirability-Based Mixture Design

Hybrid products could help bridge the gap as new alternative diets emerge in response to the demand for less animal protein, while recent studies suggest that the Western population is not yet ready to fully embrace an alternative protein-based diet. This study used a desirability-based mixture design to model hybrid spreadable cheese analogues (SCAs). The design combined milk protein concentrate (MPC), Tenebrio molitor (IF) and faba bean (FBP) flours, representing 7.1% of the formula. Nine SCAs with different MPC/FBP/IF ratios were formulated. Incorporating the IF negatively impacted the desirable texture properties. The FBP flour improved the texture (increasing firmness and stickiness and decreasing spreadability), but only when combined with MPC. Sensory analysis showed that hybrid SCAs (≤50% MPC) C2, C7 and C9 had a more characteristic cheesy flavour than the commercial plant-based reference, and sample C2 had a texture profile similar to the dairy reference. Samples containing IF (C7 and C9) showed a better flavour profile than that without IF (C2). The SCAs had higher protein and lower saturated fat, starch and sugar content than commercial analogues. The study suggests that incorporating alternative proteins in hybrid products can be an effective approach to reduce animal protein content, specifically dairy, in food formulations.

Consumer perception of restaurant and ready-to-eat cheese dips

Cheese dips are an expanding category sold as ready to eat (RTE) in grocery stores or served hot in restaurants (RST). The purpose of this study was to determine key consumer attributes for cheese dips and evaluate if key drivers of purchase for cheese dips were distinct between grocery store or restaurant purchase. An online survey (n = 931) was conducted. Participants were asked two different sets of questions based on the location they most frequently purchased and consumed cheese dip in the past 6 months, at a restaurant (n = 480) or from a grocery store (n = 451). Consumers first evaluated psychographic and agree/disagree questions regarding cheese dip and then completed maximum difference exercises focused on color and other extrinsic cheese dip attributes. Finally, an adaptive choice-based conjoint was used to determine the relative importance of cheese dip attributes. Clustering of conjoint utility scores revealed differences in preference for spiciness, but similar preferences for other attributes within both consumer groups. RTE and RST consumers indicated that their ideal cheese dip was white in color, moderately thick, and of medium spiciness with small visible pepper pieces and jalapeno pepper flavor. For both consumer groups, spiciness was the most important characteristic of cheese dips, followed by package for RTE consumers and pepper flavor and consistency for RST consumers. Regardless of consumption context, consumers have similar ideal characteristics for cheese dips. PRACTICAL APPLICATION: The primary drivers of purchase for cheese dip consumers are similar, regardless of context. Segmentation of consumer preferences reveals opportunities for product innovation. The data collected will aid in product development of cheese dips that better meet the needs of consumers.
