Fynbo cheeses salted with NaCl and with NaCl/KCl brine were evaluated for sensory characteristics over one month of ripening period. Samples were tested by a trained five-member panel. Semi-struc tured quantitative descriptive analysis scales were used to evaluate saltiness, bitterness, firmness and final quality. Typical values of saltiness and firmness were observed at 29 ripening days in the cheeses studied ( p < 0.05). Although slight bitterness was detected in cheeses salted with KCl/NaCl brine, both types of cheese were considered acceptable for commercialization ( p < 0.05).

There is vast experience in the application of sensory analysis to green Spanish-style olives, but ripe black olives (≈1 × 106 kg for 2016/2017) have received scarce attention and panelists have less experience on the evaluation of this presentation. Therefore, the study of their performance during the assessment of this presentation is critical. Using previously developed lexicon, ripe olives from Manzanilla and Hojiblanca cultivars from different origins were sensory analysed according to the Quantitative Descriptive Analysis (QDA). The panel (eight men and six women) was trained, and the QDA tests were performed following similar recommendations than for green olives. The data were examined while using SensoMineR v.1.07, programmed in R, which provides a diversity of easy to interpret graphical outputs. The repeatability and reproducibility of panel and panelists were good for product characterisation. However, the panel performance investigation was essential in detecting details of panel work (detection of panelists with low discriminant power, those that have interpreted the scale in a different way than the whole panel, the identification of panelists who required training in several/specific descriptors, or those with low discriminant power). Besides, the study identified the descriptors of hard evaluation (skin green, vinegar, bitterness, or natural fruity/floral).

Nutritional profile of white chocolate is discussed for its high contents of sugar and fat, without benefits provided by cocoa polyphenols present in milk and dark chocolate. Thus, fruit addition may increase its nutritional characteristics. In this study, white chocolates with freeze-dried and spray-dried açai ( Euterpe oleracea) were developed and their sensory characteristics were mapped through quantitative descriptive analysis and consumers' acceptance. Samples were submitted to three different conching times (6, 12, and 18 hours). Quantitative descriptive analysis results suggest type of dehydrated açai had much greater impact over samples' sensory characteristics than conching time, freeze-dried açai samples having greater intensity of açai sensory features, while spray-dried açai samples showing predominance of white chocolate sensory characteristics. Conching time had impact over texture of freeze-dried açai samples, since assessors considered sample conched for only 6 h was significantly harder and less melting than samples conched for 12 and 18 h. Consumer’s acceptance analysis results showed that freeze-dried açai samples were more widely accepted by consumers for appearance, aroma, and texture, and exhibited segmentation of acceptance for flavor and overall liking, although freeze-dried açai samples conched for 12 and 18 h were more accepted than sample conched only for 6 h.

This review summarises the main sensory methods (traditional techniques and the most recent ones) together with consumer research as a key part in the development of new products, particularly meat products. Different types of sensory analyses (analytical and affective), from conventional methods (Quantitative Descriptive Analysis) to new rapid sensory techniques (Check All That Apply, Napping, Flash Profile, Temporal Dominance of Sensations, etc.) have been used as crucial techniques in new product development to assess the quality and marketable feasibility of the novel products. Moreover, an important part of these new developments is analysing consumer attitudes, behaviours, and emotions, in order to understand the complex consumer–product interaction. In addition to implicit and explicit methodologies to measure consumers’ emotions, the analysis of physiological responses can also provide information of the emotional state a food product can generate. Virtual reality is being used as an instrument to take sensory analysis out of traditional booths and configure conditions that are more realistic. This review will help to better understand these techniques and to facilitate the choice of the most appropriate at the time of its application at the different stages of the new product development, particularly on meat products.

Abstract Napping is one of the rapid sensory profiling methods, which was established recently to meet the needs of sensory and consumer researchers. This approach provides a holistic evaluation of the tested sample through their positioning in a 2-dimensional space. The protocol of the analysis is somewhat different from the traditionally applied descriptive methods, like Quantitative Descriptive Analysis. In our review, we focus on the applicability of Napping in the field of fermented goods. The accompanying procedures are also investigated (typically Flash Profiling, CATA, and further methods), in order to understand how the combined datasets facilitate the understanding of the sensory characteristics of the products.

Honey is a very popular product because of its flavor and aroma, aswell as its nutritional quality. Studies on the sensory analysis of honey help to understand their characteristics and their impact on the acceptability of the consumer. The QDA (Quantitative Descriptive Analysis) is a technique in which trained individuals identify and quantify the sensory properties of a product or ingredient in order of occurrence. This study performed a literature review about the ADQ, its importance in the sensory analysis of honey and the main sensory attributes identified in different honey bee. Meet the sensory properties of the product is great value for the quality control of honey produced in a given region, and their attributes should be described and quantified to ensure the production of honey with the same quality standard and without amendments

Usou-se a Análise Descritiva Quantitativa (ADQ) para avaliar as características sensoriais de suco de maracujá-amarelo ( Passiflora edulis var. flavicarpa), submetido a três binômios de pasteurização (85oC/27s, 80oC/41s, 75oC/60s) e armazenamento por 120 dias sob duas temperaturas (25 ± 5oC e 5 ± 1oC). As características sensoriais (homogeneidade da cor, cor laranja, aroma característico, aroma floral, aroma doce, sabor característico, sabor estranho, sabor oxidado, sabor cozido, gosto doce e gosto amargo) foram apresentadas por meio de perfis sensoriais, junto com a descrição dos atributos sensoriais e a definição de referências para treinamento dos julgadores. Não foram detectadas diferenças significativas para a maioria das características sensoriais entre as amostras, considerando apenas os binômios de tempo-temperatura de pasteurização. Durante o armazenamento, as amostras pasteurizadas a 85oC/ 27s apresentaram as menores alterações nas características sensoriais estudadas. A pasteurização a 75oC/60s mostrou-se prejudicial, principalmente para as características de cor, aroma doce, aroma característico, aroma floral e sabor característico. O armazenamento sob refrigeração apresentou melhor tendência para a manutenção das características de qualidade sensorial do suco de maracujá. SENSORY QUALITY OF YELLOW PASSION FRUIT JUICE (Passiflora edulis var. flavicarpa) UNDER PASTEURIZATION AND STORAGE Abstract Quantitative descriptive analysis (QDA) was used to evaluate the sensory characteristics of yellow passion fruit juice ( Passiflora edulis flavicarpa) submitted to three pasteurization binomial (85oC/27s, 80oC/41s, 75oC/60s) and stored for 120 days under two different temperatures (25±5oC e 5±1oC). The sensory characteristics (color homogeneity, orange color, typical aroma, floral aroma, sweet aroma, typical flavor, off flavor, oxidized flavor, cooked flavor and sweet and bitter tastes) are presented by sensory profiles with the description of sensory attributes and reference definitions to train the judges. The results show that the pasteurization had different effects on the juice sensory attributes. However, it was not found significant differences for most of the sensory characteristics when the different time-temperature binomial of the juice pasteurization were compared. During the storage, the passion fruit juice pasteurized at 85oC/27s presented the lowest changes on the sensory attributes. The pasteurization at 75oC/60s was harmful mainly to the color characteristics, sweet aroma, characteristic aroma, floral aroma and typical flavor. Storage under refrigeration tended to keep the best juice quality characteristics.

In this work a methodology to evaluate the sensory properties of honeys has been developed. The sensory analysis was carried out by means of a quantitative descriptive analysis (QDA) method, based on several reference scales, for the coverage of the designed range for each descriptor. The peculiarity of this sensory analysis is that the reference scales have been constituted by common foodstuffs agreed upon by consensus of the panel. The main sensory attributes evaluated in the analyses were: adhesiveness, viscosity, bitterness, aroma, sweetness, acidity, color and granularity. Both the intensity and persistence of honey aromas have also been estimated, together with the classification of the identified aromatic attributes into different groups. The method was applied to 55 artisanal honeys from Madrid (Spain) with the following results: (i) the developed sensory profile sheet allowed a satisfactory description of Madrid honeys; (ii) correlations between sensory attributes of three broad groups of Madrid honeys were obtained and (iii) aroma persistence, sweetness, bitterness, color and granularity appeared as the main sensorial characteristics of honey with discrimination power between floral and honeydew honeys.

The objective of this research was to evaluate the impact of fermented whey on the sensory characteristics of ripened cheeses and consumer preference. Ripened cheeses from 24, 25, 26, 27 and 28 months were characterized. The sensory techniques used were: Quantitative Descriptive Analysis®, Temporal Dominance of Sensations and External Preference Mapping. The results showed that the ripened cheeses of 24 to 27 months they were characterized by white color, acidified milk smell, fat aroma and acidified cream smell. The cheese of 28 months of ripened was perceived as fermented milk smell, cow smell and fat smell. The dominant attributes were fat aroma, bitter aftertaste, acid aftertaste and salty. Consumers preferred cheeses from 26 and 27 months of ripening. These results demonstrate the potential use of fermented whey as an alternative to produce ripened cheeses with sensory characteristics and their relation to consumer preference.

The goal of this study was to evaluate the sensory profile of eleven peach cultivars grown in an experimental orchard located in the city of Lapa (PR, Brazil) in two seasons. The peach cultivars analyzed were Aurora I, Chimarrita, Chiripá, Coral, Eldorado, Granada, Leonense, Maciel, Marli, Premier, and Vanguarda. The sensory analysis was performed by previously trained panelists; 20 of them in the first season and 10 in the second season. The sensory evaluation was performed using Quantitative Descriptive Analysis, in which the following attributes were measured: appearance, aroma, flesh color, flesh firmness, flavor, and juiciness. The results showed preference for sweet, soft, and juicy fruits. Chimarrita, Chiripá, and Coral fruits showed better sensorial performance than the other peach cultivars. It was also verified that the analysis of the attributes aroma, flesh firmness, and flavor is enough for performing the sensory profile of peach fruits for in natura consumption.
