SENSORY EVALUATION AND SUITABILITY FOR FRESH-CUT PRODUCE OF WHITE PEACH [PRUNUS PERSICA (L.) BATSCH] 'SETTEMBRINA DI BIVONA'
2015
âSettembrina di Bivonaâ peaches were cut into slices to assess their suitability as fresh-cut produce. Untreated (control) and treated with calcium lactate fresh cut slices were closed in plastic boxes for 24 hours (T1) or five days of storage (T2) at 5°C, and then placed at 20°C to assess consumersâ liking. Soluble solids content, titratable acidity, firmness and pH were measured. A sample of n = 750 consumers was selected taking into consideration three variables: age (from 25 to 55 years old), professional status (employed) and aptitude to buy fresh-cut fruit for personal use. A systematic sampling was used, with a detection point based in a properly selected supermarket during t…
Fat and salt contents affect the in-mouth temporal sodium release and saltiness perception of chicken sausages
2013
In cooked meats, sodium chloride is involved in taste, texture and flavour release. So a reduction in the salt content may have an impact on overall perception and acceptability. The aim of this study was to evaluate the influence of composition on sodium release and saltiness intensity in chicken sausages. The rheological properties of the sausages differed according to composition. Temporal sodium release and temporal saltiness intensity were evaluated by four selected subjects when eating sausages. At each time point, the effect of the salt level in sausages on sodium release was positive and highly significant. The effect of lipids on sodium release was negative. Concerning perception, …
Different sensory aspects of a food are not remembered with equal acuity
2009
International audience; In the present study, food memory for three sensory aspects involved in food perception, taste, texture and aroma, is compared. Participants received a lunch including a custard dessert (target) under incidental learning condition. One day later, participants were presented with samples identical to the target and with distractors varying either in sweetness, thickness or cherry aroma. Memory was assessed by an absolute recognition question (“Did you eat this sample yesterday?”) and by relative questions (“Is this sample less, equal or more sweet than the sample you ate yesterday?”). Results showed better memory performance for sweetness than for the two other sensor…
When a new technological product launching fails: A multi-method approach of facial recognition and E-WOM sentiment analysis
2018
Abstract The dual aim of this research is, firstly, to analyze the physiological and unconscious emotional response of consumers to a new technological product and, secondly, link this emotional response to consumer conscious verbal reports of positive and negative product perceptions. In order to do this, biometrics and self-reported measures of emotional response are combined. On the one hand, a neuromarketing experiment based on the facial recognition of emotions of 10 subjects, when physical attributes and economic information of a technological product are exposed, shows the prevalence of the ambivalent emotion of surprise. On the other hand, a nethnographic qualitative approach of sen…
Accuracy and Completeness of Drug Information in Wikipedia: A Comparison with Standard Textbooks of Pharmacology
2014
The online resource Wikipedia is increasingly used by students for knowledge acquisition and learning. However, the lack of a formal editorial review and the heterogeneous expertise of contributors often results in skepticism by educators whether Wikipedia should be recommended to students as an information source. In this study we systematically analyzed the accuracy and completeness of drug information in the German and English language versions of Wikipedia in comparison to standard textbooks of pharmacology. In addition, references, revision history and readability were evaluated. Analysis of readability was performed using the Amstad readability index and the Erste Wiener Sachtextforme…
Australian Modernist Theatre and Patrick White’s the Ham Funeral (1961 [1947])
2017
For a considerable period of time, literary Modernism has been mainly associated with the study of the novel and poetry rather than drama perhaps due to New Criticism’s emphasis on the text and disregard of performance. This profound anti-theatrical thrust of Modernism has to be, most certainly, re-examined and reassessed, particularly within the context of Australian literature and, more specifically, Australian theatre. That Australian modernist theatre has been inconspicuous on the world stage seems to be an obvious and undisputable statement of facts. Yet, with Patrick White, English-born but Australian-bred 1976 Nobel Prize winner for literature, Australian low-brow uneasy mix of Briti…
Intraspecific diversity of Lactobacillus curvatus, Lactobacillus plantarum, Lactobacillus sakei, and Leuconostoc mesenteroides associated with vacuum…
2006
The intraspecific diversity of Leuconostoc mesenteroides, Lactobacillus curvatus, Lactobacillus sakei, and Lactobacillus plantarum was analyzed by randomly amplified polymorphic DNA (RAPD) PCR with universal primers M13 and T3. The study included 100 reference strains and 210 isolates recovered from two vacuum-packed Spanish meat products, fiambre de magro adobado and morcilla, previously identified by rDNA-restriction fragment length polymorphism profiles. The RAPD-M13 profiles identified isolates at species level in L. plantarum and L. mesenteroides, while RAPD-T3 provided profiles in L. sakei. The combination of RAPD-M13 and RAPD-T3 fingerprints revealed a total of 17 profiles in L. mese…
Occurrence of fumonisins B1 and B2 in broa, typical Portuguese maize bread
2007
Fumonisin B1 (FB1) and fumonisin B2 (FB2) are mycotoxins mainly produced by Fusarium verticillioides, and Fusarium proliferatum, fungi species most commonly isolated from maize. The natural occurrence of FB1 and FB2 in broa, typical Portuguese maize bread, was evaluated in 30 samples. Twenty five were found positive with levels ranging from 142 to 550 [mu]g kg- 1. The limit established by the European regulations was exceeded by 27% of the samples. The tolerable daily intake for fumonisin B1, and B2, alone or in combination, for all of the analysed samples, was lower than 2 [mu]g kg- 1 body weight per day established by the European Commission. http://www.sciencedirect.com/science/article/B…
Dietary intake of ochratoxin A from conventional and organic bread
2006
Ochratoxin A (OTA) was extracted from 100 bread samples by using accelerated solvent extraction (ASE) and analyzed with liquid chromatography coupled with fluorescence detection. The presence of OTA was confirmed by methyl-ester derivatization. Bread samples were bought from different bakeries and supermarkets, 74 of non-organic and 26 of organic bread. The incidence of OTA varied between 20.3% and 23.0% for non-organic and organic bread, respectively. The highest values were obtained with non-organic versus organic products, five samples exceeded the European maximum permitted limit of OTA (3 ng/g) for this product. Estimated daily intake of OTA in this study was 1.6 ng/kg b.w./day. This v…
Determination of Fungi and Multi-Class Mycotoxins in Camelia sinensis and Herbal Teas and Dietary Exposure Assessment
2020
In this paper, a study of fungal and multi-mycotoxin contamination in 140 Camellia sinensis and 26 herbal teas marketed in Latvia is discussed. The analysis was performed using two-dimensional liquid chromatography with time-of-flight mass spectrometry (2D-LC-TOF-MS) and MALDI-TOF-MS. In total, 87% of the tea samples tested positive for 32 fungal species belonging to 17 genera, with the total enumeration of moulds ranging between 1.00 ×
