The scope goes further than the usual technological measures that modulate sensory properties and includes the psychological and cross-modal influences, where the sensory modification is on the subject’s brain and not on the object’s physical-chemical properties. The beverage industry usually addresses the question of modifying sensory characteristics by meeting the innate attraction for sweetness either by adding different sweetening agents, different aroma molecules, or changing dishware forms, which are known to increase the in-mouth sweet perception. Non-nutritive sweeteners have been used as substitutes for nutritive sweeteners with the goal of preventing obesity and dental caries. The main factor responsible for the difference in taste between beverages containing a nutritive sweetener and those containing a non-nutritive sweetener is the temporal profile of sensory attributes. However, Gotow et al. [1] demonstrated that this difference was only observed in water and not in coffee beverages, probably because of flavor properties that masked the sweetener effect. The cross-modal flavor–taste interactions also revealed the importance of the matrix effect as described by Wang et al. [2] using skim milk. These authors showed that a vanilla aroma did enhance the perceived sweetness while this enhancing effect was lower than that of sucrose on the vanilla flavor. The cross-modal interactions also include visual and taste senses. In particular, research indicates that roundness (as opposed to angularity) is consistently associated with an increased sweetness perception. However, Machiels [3] did not confirm these results using two different cup forms (round versus angular) with a butter milk drink and a mate-based soft drink. Interestingly, a correspondence was found between the angular cup and a more bitter taste only for the soft drink. The sweetener sucrose may also be used for other purposes than increasing sweetness [4]. These authors showed that it also affects the texture and creaminess of a new product based on partially demineralized sweet whey and gelatin added to milk powder and cassava starch. Creaminess and firmness were also promoted by the cassava starch. Overall, these four articles highlight that food or beverage matrixes exert a significant effect on taste and mouth-feel studies and are indispensable to validate preliminary assessments using water solutions. Wines are also a frequent object of sensory studies, gathering researchers with different scientific backgrounds. The shape and size of the wine glass was shown to affect the different wine aromas in the headspace [5] Moreover, Spence and Wang [6] demonstrated that the quality of the wine was rated as higher and the celebratory mood of the participant was also higher following the sound of the cork pop when compared with a screw-cap opening. The cross-modal interaction received here of another input from the senses of hearing, smell, and taste influences hedonic responses. Under a different scope, off-flavors also deserve the attention of researchers. For instance, the world-famous Chardonnay from Burgundy may be affected by oxidative notes that indicate premature aging [7] The highly debated “horse sweat” taint was also reviewed, encompassing technical preventive measures and the influence of volatile phenols on sensory attributes [8]. This special issue enables consumers to be aware of the work that is being carried out by leading research teams in areas that may be regarded as case studies for the whole of the food and beverage industries.

Received: 22 January 2010; in revised form: 23 February 2010 / Accepted: 9 March 2010 / Published: 22 March 2010 Abstract: The biologically active compounds in wine, especially phenolics, are responsible for reduced risk of developing chronic diseases (cardiovascular disrease, cancer, diabetes, etc.), due to their antioxidant activities. We determined the contents of total phenolics (TP) and total flavonoids (TF) in selected Serbian white wines by colorimetric methods. Total antioxidant activity (TAA) of the white wines was analyzed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity assay. Međaš beli had the highest content of TP, TF and TAA. The radical scavenging capacity (RSC) and total antioxidant activity (TAA) of white wines were 15.30% and 1.055 mM Trolox equivalent, respectively. Total phenolic (TP) and total flavonoid (TF) contents in white wines ranged from 238.3 to 420.6 mg gallic acid equivalent per L of wines and 42.64 to 81.32 mg catechin equivalent per L of wines, respectively.

  • Formulation and Sensory Analysis of a Ketogenic Snack to Improve Compliance with Ketogenic Therapy
    Formulation and Sensory Analysis of a Ketogenic Snack to Improve Compliance with Ketogenic Therapy Russell J. Owen* College of Agricultural and Life Sciences, University of Florida Limited dietary choices in the ketogenic diet may compromise compliance and reduce overall quality of life, and the low provision of fiber may further diminish quality of life. The purpose of this study was to develop highly acceptable high fiber, ketogenic snacks. Broccoli bites and crab rangoon were developed approximately at a 3.5 to 1 ketogenic ratio. The snacks were formulated using fiber isolates, pea hull fiber, hydroxypropyl methylcellulose and inulin as an alternative breading for frying. Sensory evaluation was carried out by students and staff at the University of Florida to determine the acceptability of overall taste, mouthfeel, and appearance of the snacks. Using a hedonic scaling method, panelists (n=67) determined acceptability, with 1 indicating extreme dislike, and 9 indicating extreme liking. For the broccoli bites, the mean hedonic rankings for overall taste, mouthfeel, and appearance were 6.54 ± 1.78 (mean ± SD), 6.27 ± 1.71, and 5.85 ± 1.73, respectively. For the crab rangoon, the mean hedonic rankings for overall taste, mouthfeel, and appearance were 5.60 ± 1.86, 4.93 ± 2.00, and 5.79 ± 1.78, respectively. In addition, hedonic rankings for the overall taste, mouthfeel, and appearance for the crab rangoon were rated as 6 (like slightly) or higher by 58.2%, 47.8%, and 67.2% of panelists, respectively. Hedonic rankings for the overall taste, mouthfeel, and appearance for the broccoli bites were rated as 6 (like slightly) or higher by 76.1%, 73.1%, and 62.7% of panelists, respectively.

This situation is extremely unsatisfactory and needs to be clarified. ^Ornebody may wonder to see that the definition of meat quality is placed into the analytical Session at this congress. However, it has to be stressed that meat quality as we will see it is lr>deed a matter of analytical measurements. Of course in the latter not only those methods are included which are well known in the classical chemical analysis but all methods available, giving us objective information about the subject "meat" in the widest sense. HISTORICAL APPROACHES: One of the best known and most quoted definitions of quality in connection with meat was given by Hammond (1955): "Quality can best be defi- aed as that which public likes best and for which they are prepared to pay more than ava- |a9e prices". ^iil show you later in this presentation that this interpretation which takes only the aspects Profit into the consideration cannot be accepted for scientific purposes.

Venizelou Ave., Athens, Greece Received 21 June 2013, revised 8 May 2014, accepted 23 May 2014, available online 20 November 2014 Abstract. Since the formulation of the “French paradox”, red grape wines are generally considered to be health-promoting products rather than culpable alcoholic beverages. The total wine production, totalling an equivalent of 30 billion 750 mL bottles in 2009, only verifies the fact that global demand is increasing and that the polyphenols present in wines are accounting for a significant proportion of the daily antioxidant intake of the general population. Both statements justify the interest of new regions to be self-sufficient in the wine production. Novel cold tolerant hybrid grape varieties also make it possible to produce wines in regions where winter temperatures fall below – 30 °C and the yearly sum of active temperatures does not exceed 1750 °C.
