And Performance

The relationship between food-related individual characteristics and performance in sensory evaluation was investigated. The study focused on differences in discriminative ability and perceptual sensitivity according to levels of product involvement or food neophobia during the intensity rating of sensory attributes in consumer profiling. Consumers (N = 247) rated the intensity of attributes for seven flavored black tea drinks and completed the Food Neophobia Scale and the Personal Involvement Inventory measuring product involvement with the flavored black tea drink. In the higher product involvement (IH) group and the lower food neophobia (NL) group, the number of sensory attributes representing the sample effect and of subsets discriminating the samples were greater, and more total variance of the samples was explained. The higher the product involvement or the lower the food neophobia, the greater the differentiation in characterizing samples with more attributes in the intensity ratings. Interestingly, the high food neophobia (NH) group showed less active performance compared to the NL group during the sensory evaluation overall, but the NH group was more concerned about unfamiliar attributes and samples. The results implied that the positive attitude resulting from high product involvement and low food neophobia may induce more active behavior and better performance during the sensory evaluation.

Analytical Approaches

Growing demand for sustainable food has led to the development of meat analogs to satisfy flexitarians and conscious meat-eaters. Successful combinations of functional ingredients and processing methods result in the generation of meat-like sensory attributes, which are necessary to attract non-vegetarian consumers. Sensory science is a broader research field used to measure and interpret responses to product properties, which is not limited to consumer liking. Acceptance is evaluated through hedonic tests to assess the overall liking and degree of liking for individual sensory attributes. Descriptive analysis provides both qualitative and quantitative results of the product’s sensory profile. Here, original research papers are reviewed that evaluate sensory attributes of meat analogs and meat extenders through hedonic testing and/or descriptive analysis to demonstrate how these analytical approaches are important for consumer acceptance. Sensory evaluation combined with instrumental measures, such as texture and color, can be advantageous and help to improve the final product. Future applications of these methods might include integration of sensory tests during product development to better direct product processing and formulation. By conducting sensory evaluation, companies and researchers will learn valuable information regarding product attributes and overall liking that help to provide more widely accepted and sustainable foods.

Rheological Characterization

The effects of ingredients on the sensory evaluation and rheological behavior of two brands of mayonnaise were examined in this work. Mayonnaise samples were examined by Analytical Descriptive Test and Ranking Test of Preference. The rheological parameters were determined at 25°C using a concentric cylinder Brookfield rheometer with a spindle SC4-34. The results showed that standard mayonnaise as opposed to low-fat mayonnaise gained higher grades for most sensory attributes. All samples were found to exhibit non-Newtonian pseudoplastic behavior described by Herschel–Bulkley model. A decrease in the yield stress, viscosity and shear stress with the decrease in oil content was observed in all products, which confirm that the rheological characterization is capable of distinguishing rather well between mayonnaises made with different formulation.

Abstract Noodles promote health as a source of essential nutrients and fiber. This study evaluated the effects of incorporating various levels of betel leaf extract on the quality and sensory acceptability of Hokkien noodles. Hokkien noodles incorporated with betel leaf extract (0, 5, 10, 15, and 20% based on flour weight) were prepared from wheat flour with a moisture content of 14%. The hardness, elongation, adhesiveness, color, and sensory evaluation of the noodles were then determined. Results clearly show that the incorporation of betel leaf extract at various levels led to the structural modification of the noodles and to a soft product compare to the control. However, the product scores in all sensory attributes were higher than the control scores. The sample was incorporated 15% betel leaf extract had the best acceptance quality wherein the beneficial effects of betel leaf polyphenols can be utilized.

AbstractThe aim of the research was to compare the possibility of distinguishing the cultivars of processed beetroots using image analysis technique and sensory evaluation. The differentiation of processed samples was tested for freeze-dried beetroot ‘Czerwona Kula’ and ‘Cylindra’, lacto-fermented beetroot ‘Czerwona Kula’ and ‘Cylindra’, freeze-dried lacto-fermented beetroot ‘Czerwona Kula’ and ‘Cylindra’. The textures from the images of quarters of root slices, as well as sensory attributes evaluated by expert sensory assessors, were determined. The differences in the means of selected textures from color spaces Lab, RGB and XYZ for different cultivars of raw and processed beetroots were observed. The raw beetroots ‘Czerwona Kula’ and ‘Cylindra’ were discriminated with the accuracy of up to 94.5% for models built based on selected texture from color space RGB. In the case of processed beetroots ‘Czerwona Kula’ and ‘Cylindra’, the accuracy reached 96% (color space Lab) for freeze-dried beetroots, 99% (color space Lab) for lacto-fermented beetroots, 98.5% (color space Lab) for freeze-dried lacto-fermented beetroots. In the case of sensory attributes, no statistically significant differences were observed between the beetroot samples.

Grape juices are blended in order to balance the organoleptic characteristics of juice, as well as to reduce off-season costs. The aim of this study was to evaluate the acceptance of consumers, through sensory analysis, of ‘Bordô’, ‘Niagara Rosada’, ‘BRS Nubia’ and ‘Isabel’ grape juices and their blends. The experiment was conducted during two periods. In the first, the grape juices analyzed were: ‘Niagara Rosada’ 100%, ‘Bordô’ 100%, ‘Isabel’ 100%, ‘Isabel’ 90% + ‘Bordô’ 10% and ‘Isabel’ 80% + ‘Bordô’ 20%. In the second, the following juices were evaluated: ‘Bordô’ 100%, ‘Niagara Rosada’ 100%, ‘Bordô’ 75% + ‘Niagara Rosada’ 25%, ‘Bordô’ 50% + ‘Niagara Rosada’ 50%, ‘Bordô’ 25% + ‘Niagara Rosada’ 75% and ‘BRS Nubia’ 100%. The juices were obtained by the ‘Welch’ process by steam entrainment. For the sensory evaluation, six tasters evaluated the following attributes in each period: color, aroma, flavor, body and overall acceptability, using a 7-point hedonic scale. The ‘Niagara Rosada’ juice 100% presents low acceptance, while the ‘Bordô’ and ‘Niagara Rosada’ juices up to 1:1 (v:v) show high acceptance, as well as ‘Bordô’ and ‘Isabel’ blends, confirming the importance of ‘Bordô’ juice for grape juice blends. The ‘Nubia’ juice 100% may be an alternative for grape juice blends due to its intense color.

Self Organizing

Sensory analysis has an important impact on food production since its results can help the understanding of consumers’ perceptions about the products. Thus, many methods have been proposed and applied to quantify sensory attributes of food products. In this paper we proposed a methodology, using Kohonen's Self-Organizing Maps and K-means algorithm, to classify food samples through the responses, provided by human evaluators, for their attributes such as aroma, flavor, appearance and texture. Conducted experiments in sensory analysis to determine the acceptance of new gelatins produced from chicken feet and new wines produced from spares of Açaí and Cajá confirm that proposed methodology is suitable for the investigated purpose.

Abstract Although there have been recent studies of the roasted peanut sensory attribute of roasted peanut (Arachis hypogaea L.), there is little information on the factors influencing the sweet and bitter attributes. A study was conducted to test the significance of the effects of genotype, environment, and their interaction on the sweet and bitter attributes, to estimate genotypic means of these sensory attributes, and to determine an efficient scheme of resource allocation for multiple-site testing of breeding lines for sweet and bitter attributes. Samples of sound mature kernels from 17 genotypes grown at 42 different location-year combinations were stored under 5 C and 60% RH, roasted to nearly common color, ground into paste, and tasted by a trained sensory evaluation panel. Results for the roasted peanut attribute were similar to those found in previous studies. Significant variation among years was observed for bitter but not for sweet. There were no consistent differences among the three main peanut production regions for either attribute, but there was significant year-by-region interaction for sweet. Variation among locations within years and regions was significant for both attributes as was variation among genotypes. The mean flavor profile for the runner market class was significantly better than the mean for the virginia class in sweet, bitter and roasted peanut, but the distributions of the two classes did overlap. Significant correlations of genotypic means for the three attributes indicated that chemical assays for currently unidentified sweet or bitter principles could be used for indirect selection to improve roasted peanut attribute without the need for expensive and time-consuming sensory evaluation. Significant genotype-by-year interaction for bitter makes it necessary to acquire sensory data from 2 yr with three replications at each of four locations or two replications at each of five locations to differentiate statistically between means differing by half a flavor intensity unit. The precision of comparisons for sweet and roasted peanut will be more precise than that for bitter at a given arrangement of testing resources.
