“Téa Lémi” is a traditional wine made from pummelos by the Kapsiki in the Far-North of Cameroon. Despite its importance as a source of income for the country people, the know-how supporting production of this beverage and its quality attributes still remain unknown. Hence, this study was aimed at describing the processing and quality of “Téa Lémi” produced and marketed in northern Cameroon. The field investigation and the ethnographical technique were used to describe the production process. Physicochemical, phytochemical, and microbiological properties of the beverage were examined using referenced techniques. Quantitative descriptive analysis was used for describing the sensory profile of the wine. Surveys showed that processing of the grapefruit wine is typically artisanal. This can be seen by the uncontrolled addition of some ingredients such as sugar, extract of banana, and honey and a significant fermentation step started by wild, unselected yeasts. The physicochemical analyses revealed that the wine had an acid pH of around 3.84, with a total acidity between 7.72 g/L and 8.79 g/L. The alcohol and soluble solids contents were 14% (v/v) and 12 °Brix, respectively. Total sugar and conductivity values ranged from 57.8 to 96.8 g/L and 573 to 686 μS/cm. Mean contents of polyphenols and flavonoids of 616.4 mg PE/L and 322.5 mg QE/L and an antioxidant capacity of 261.03 mg TE/L have been revealed in the indigenous wine, respectively. The assessment of hygienic quality showed alarming sign of microbiological contamination revealed by total aerobic bacteria and spore-forming bacteria counts beyond the critical level. The good sensory quality (13 out of 20) of the grapefruit wine seemed to be linked to the sweetness (r = 0.999; p < 0.001 ) and odor/flavor (r = 0.997; p < 0.001 ). The beverage has been described by the panel as pale yellow colored, slightly tart, and bitter accompanied by some fruity esters and sweet notes of citrus and caramelized sugar.

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.

Applicable legal regulations allow Polish farmers to sell agricultural produce and products made from them. This activity enables the creation of a new market of natural food, which is competitive in relation to industrially produced food. The aim of the research was to compare the quality of strawberry jam available on the market with its counterpart produced on farms. The studies compared the extract content and sensory quality of 11 strawberry jams available in retail with jam from the Kashubian Strawberry certified with EU PGI. The content of the extract and intensity of 17 sensory markers characterising the appearance, consistency, taste and aftertaste of strawberry jam were assessed. The study was conducted using quantitative descriptive analysis – QDA. The strawberry jam which was compared was characterized by a very large diversity of sensory characteristics in terms of brightness, opacity, colour intensity of red and softness. The smaller variation was characterised by an intensity of features relating to elasticity, acidic and chemical taste as well as sweet, dry and fruity aftertaste. Industrial jams were similar in terms of quite a perceptible sweet taste and viscosity and average perceptible fruit taste. The jam obtained from the Kashubian Strawberry was not inferior to the quality of industrial-grade jam. It stood out in comparison with a high content of extract, attractive red colour and greater softness. Compared to commercial jams, it had a higher intensity of fruity, sweet and sour taste, and a distinctly fruity aftertaste, with no foreign notes.

Sensory characteristics (evaluated by quantitative descriptive analysis and as the hedonic ratings) of sprouts obtained from lentil, Mung bean, pea and soybean sprouts were assessed. It was found that the palatability of sprouts was negatively correlated with bitterness and astringency of these products. However, the statistically significant correlation between the content of total phenolic compounds and negative sensory attributes (bitterness and astringency) was not found.

Consumer studies on acceptability of pork from immunocastrates (IC) and entire males (EM) are of primary importance, if these alternatives are to replace surgical castration (SC) of piglets. Data on the sensory traits and consumers acceptance of IC and EM meat products are still limited. Therefore, the purpose of the study was to (1) describe the sensory profile by quantitative descriptive analysis and (2) test the perception and consumer liking of salami (dry-fermented sausage) and pancetta (dry-cured belly) from EM, IC and SC animals. The consumer tests included the scaling method and check-all-that-apply. Profiling showed that EM products were scored lower in the overall sensory quality compared to IC or SC. EM products differed mainly from IC and SC in the intensity of the manure, sweat odor and flavor, persistent impression and texture (hardness, gumminess and easy to fragment). Salami samples did not differ in liking. In pancetta, the differences were significant for odor liking and visual quality (expected liking). Consumers did not perceive EM products as inferior in terms of liking, while sensory profiling indicated differences for boar taint presence and texture. Using meat originating from IC did not result in any differences in consumers acceptance as compared to products from SC.

Tape ketan (fermented glutinous rice) and tape singkong (fermented cassava) are traditional Indonesian foods produced by fermenting carbohydrate sources using ragi as starter culture. Those products known to contain high number of lactic acid bacteria (LAB). The purpose of the study was to evaluate the sensory characteristics of tape ketan and tape singkong from different household industry in Bogor, to identify the sensory profile, and to evaluate the correlation between LAB density and sensory attribute. The research was started by survey to household tape industries, followed by sensory analysis of rating hedonic and Quantitative Descriptive Analysis (QDA), and LAB analysis. Data analysis of rating hedonic was done by ANOVA and post-hoc Duncan test, while data analysis of QDA was done by Principle Component Analysis (PCA). Samples of tape ketan were taken from two different home industries (BK and LK), while samples of tape singkong were taken from four different home industries (CT, NG, SH, TS). Hedonic rating test showed that the most preferred sample overall was tape ketan BK and tape singkong CT. QDA results showed that tape ketan BK was characterized by its sweetness, rice-like aroma, rice-like taste, and texture, while tape ketan LK was characterized by alcoholic aroma, alcoholic taste, sourness, and color. Tape singkong NG were characterized by sour aroma, alcoholic aroma, alcoholic taste, and color. Specific characteristic of tape singkong CT was bitterness and bitter aftertaste, SH was sweetness, and TS was texture. LAB of tape ketan BK (8,5 log cfu/g) was higher than LK (7,9 log cfu/g). Tape singkong with highest density of LAB was TS (8,1 log cfu/g), followed by CT (7,2 log cfu/g), NG (7,0 log cfu/g), and SH (6,5 log cfu/g). There was no correlation between the density of LAB and descriptive score of sourness, alcoholic taste, and sweetness.
