Sensory Quality and Consumer Liking of Carrot Cultivars of Different GenotypeThe aim of this work was to determine sensory quality differentiation in various carrot cultivars of different genotype - with orange, purple and yellow storage roots. Consumer's test for liking carrots was performed in order to find consumer's preference level for carrots types and to determine the relationship between sensory profiles and consumer's attitude to carrots. An approach was also done to find correlations between descriptors of sensory quality and liking level, and to determine which sensory quality descriptors significantly affect overall sensory quality impression. The two-year studies were carried out in Warsaw Agricultural University in 2005-2006. Carrots were grown on the experimental field of the University. Eight cultivars of different storage root colour and shape were chosen: 'Perfekcja', 'Interceptor', 'Vita Longa', 'Nebula', 'Deep Purple', 'Purple Haze', 'Mello Yello', 'White Satin'. The trained panel, consisting of 12 persons, carried out the evaluation, using the quantitative descriptive analysis method (QDA). At the first part of QDA procedure, experts generated a set of 13 descriptors for odour, appearance, texture and flavour/taste of carrot. Consumer test of carrots liking was also performed by 65-person group of volunteers in different age of both sexes. For this evaluation non-structural scale was also used, with anchoring points: 'I do not like it' - 'I like it very much'. Consumer liking for colour, flavour and overall liking was evaluated. Principal component analysis and regression analysis were performed on obtained data. Results show large differentiation of sensory traits of investigated cultivars. The biggest influence on overall quality exerted off-odour intensity, flesh firmness, flavour of raw carrot intensity, bitter taste and off-flavour intensity. Consumer's preference was also differentiated and highest scores for liking got orange coloured cultivars. In respect of flavour liking, 'Perfekcja', 'Interceptor' and 'Nebula' were the most desired cultivars by consumers of both sexes, and 'Mello Yello' was the lowest desired cultivar. There were small differences in preference between females and males. Flavour liking of carrots was strongly and positively correlated with flesh juiciness and crunchiness of roots.

Coffee pulp, a by-product of coffee production, contains valuable compounds such as caffeine and chlorogenic acid with high antiradical activity. In this study, aqueous solutions of β-cyclodextrin (β-CD) were used as a non-conventional solvent for the extraction of targeted compounds from coffee pulp. The parameters of β-CD concentration (Cβcd), liquid-to-solid ratio (L/S), and temperature (T) were evaluated based on the antiradical activity (AAR) and the caffeine content (CCaf). The optimum operational conditions were found to be Cβcd: 9.25 mg/mL, L/S: 30 mL/g and T: 80 °C. The sensory profiles of brews prepared with coffee and coffee pulp with or without cyclodextrin were studied with quantitative descriptive analysis. The brew from the by-product had fruity, botanic, sweet and sourness sensory properties, and cyclodextrin was found to be able to affect the overall taste of the brew.

The aim of this study is to comprehensively investigate the aroma composition and sensory attributes of Vidal icewine fermented with four yeast strains (ST, K1, EC1118, and R2). A total of 485 kinds of volatile components were identified by comprehensive two-dimensional gas chromatography-time of flight mass spectrometry, among which 347 kinds of volatile compounds were the same in four kinds of sample. The heat map was conducted with 156 volatile compounds, which have aroma contributions, and the analysis results identified the characteristics of the aroma composition of icewine fermented with different yeasts. Quantitative descriptive analysis was performed with a trained panel to obtain the sensory profiles. The aroma attributes of honey and nut of the icewine fermented by R2 were much higher than others. Partial least squares discriminant analysis further provided 40 compounds that were mainly responsible for the differences of the aroma characteristics of the icewines fermented by four yeasts. This study provides more data on the current status of Vidal icewines by main commercial yeasts.

The present study evaluated the sensory quality of chocolates obtained from two cocoa cultivars (PH16 and SR162) resistant to Moniliophtora perniciosa mould comparing to a conventional cocoa that is not resistant to the disease. The acceptability of the chocolates was assessed and the promising cultivars with relevant sensory and commercial attributes could be indicated to cocoa producers and chocolate manufacturers. The descriptive terminology and the sensory profile of chocolates were developed by Quantitative Descriptive Analysis (QDA). Ten panelists, selected on the basis of their discriminatory capacity and reproducibility, defined eleven sensory descriptors, their respective reference materials and the descriptive evaluation ballot. The data were analyzed using ANOVA, Principal Component Analysis (PCA) and Tukey's test to compare the means. The results revealed significant differences among the sensory profiles of the chocolates. Chocolates from the PH16 cultivar were characterized by a darker brown color, more intense flavor and odor of chocolate, bitterness and a firmer texture, which are important sensory and commercial attributes. Chocolates from the SR162 cultivar were characterized by a greater sweetness and melting quality and chocolates from the conventional treatment presented intermediate sensory characteristics between those of the other two chocolates. All samples indicated high acceptance, but chocolates from the PH16 and conventional cultivars obtained higher purchase intention scores.

Caciottina massaggiata di Amaseno, a typical dairy product of the Lazio Region prepared from buffalo milk, was analysed for moisture, fat, protein, pH, and acidity content at different storage (0, 3, 6, and 9 months after production). Cheeses were also evaluated for various sensory attributes (taste, flavour, texture, and overall acceptability) during storage. We evaluated the flavour profile and acceptability of Caciottina cheeses of varying maturity using a descriptive analysis. Descriptive sensory profiles of selected cheeses were determined using a trained panel (n = 12) and an established cheese flavour sensory language. In quantitative descriptive analysis a trained panel rated the cheeses for colour, odour, taste and texture. In the affective tests the panellists evaluated the samples for overall quality. The results proved that months of production had significant effects on the sensory quality of the cheeses.
