Volatile compounds in wines made from dehydrated grapes contained more terpenes and norisoprenoids (β-ionone, β-damascenone) when compared to wine made from the original fruit. (oregonstate.edu)
Extraction process preserves the aromatic precursors (terpenes and norisoprenoids) present in wood. (enartis.com)
Concentrations4
Concentrations of C(13)-norisoprenoids and bound forms of nerol and geraniol were positively correlated with their concentrations in the corresponding wines. (oregonstate.edu)
Base wines for the production of Durello sparkling wine were characterized by high concentrations of norisoprenoids and esters which can contribute to the fruity and tobacco aroma of wine. (infowine.com)
Two aromatic compounds, norisoprenoids and terpenes, which can, in different concentrations, lend the drink a smell of baked apples, flowers, saffron, citrus, spicy cloves or fish oil, were found to have been significantly affected in wine kept in clear bottles after just a week in the grocery store. (newedgetimes.com)
However, higher concentrations of glycosylated monoterpenes and C-13-norisoprenoids were measured in Sangiovese and Vermentino berries treated with UV-B. CONCLUSION This study provides new insights on the effect of postharvest UV-B radiation on berry secondary metabolism, highlighting a different modulation between varieties and suggesting the potential use of this technique to increase some nutraceutical and quality characteristics of grape berry.

Aromatic compounds1
Norisoprenoids are a diverse class of aromatic compounds that contribute to the varietal character of many wines, especially in aromatic varieties such as Riesling. (ucdavis.edu)
Fruity2
While ethanol has a strong suppressing effect on fruity odour, woody smelling hydrocarbons called norisoprenoids and dimethyl sulfide interact with the esters to boost it. (chemistryworld.com)
Light and UV rays influence aromas by reducing pyrazines and forming thiols, norisoprenoids (fruity aromas) and terpenes (muscat-like aromas). (sauvignonselection.com)
Grape2
The correlation between carotenoids and C13-norisoprenoids in the grape berries was compound-dependent, suggesting dependency on enzyme activity and specificity. (oregonstate.edu)

Carotenoids2
In the vineyard, increased sunlight exposure to the grapes seems to encourage the development of carotenoids, and subsequently increase the levels of norisoprenoids in finished wine. (ucdavis.edu)

Alcohols1
Other compounds (norisoprenoids, fatty acids and alcohols) were present in traces. (ives-openscience.eu)
Volatile1
The free fraction of berry volatile organic compounds increased in UV-B-treated Aleatico and Moscato bianco berries, especially C-13-norisoprenoids and volatile phenols, as well as key monoterpenes, such as the linalool derivatives. (unipi.it)
Wine4
Norisoprenoids are detectable at very low levels: sensory thresholds have been reported as low as 2 ng/L, although it is more likely that they begin to impact wine character at levels between 2 and 10 µg/L. Their concentration in wine tends to fall close to these threshold values, although levels of TDN in aged Riesling can reach 50+ µg/L. (ucdavis.edu)

But during fermentation and as wine ages, they are released from the sugars via hydrolysis and eventually develop into the aromatic norisoprenoids. (ucdavis.edu)

Terpenes4
Volatile compounds in wines made from dehydrated grapes contained more terpenes and norisoprenoids (β-ionone, β-damascenone) when compared to wine made from the original fruit. (unboundmedicine.com)
Volatile constituents of commercial black-ripe table olives (Olea europaea) from the United States, Spain, Egypt and Morocco were analyzed by gas chromatography and gas chromatography-mass spectrometry (GC-MS). Dynamic headspace sampling was used to isolate a variety of aldehydes, alcohols, esters, ketones, phenols, terpenes, norisoprenoids, and pyridines. (usda.gov)
Terpenes, C13-norisoprenoids, acetate esters, ethyl esters, and fatty acids served as the impact volatiles that contributed to the enhanced aroma traits. (bvsalud.org)
SiF specifically increased the contents of C13-norisoprenoids, terpenes, and ethyl esters, while EE enhanced varietal volatile content rather than those of fermentative ones. (bvsalud.org)
Esters1
Wines from the first harvest date were characterised by an abundance of lipoxygenase derived compounds, norisoprenoids and sulfur-containing compounds whereas a significant increase in some acetate esters was observed in wines produced from the more mature grapes. (fmach.it)

Markers1
This study presents the most detailed terpenic and norisoprenoids elderflower profiling, and linalool oxides were proposed as markers for a more expedite assess to the impact of postharvest conditions. (ua.pt)
