Although to date more than 10 000 volatile compounds have been characterized in foods, a literature survey has previously shown that only 226 aroma compounds, assigned as key food odorants (KFOs), identified actively contribute the overall aromas of about 200 such beverages, meat products, cheeses, or baked goods. Currently, multistep analytical procedure involving human olfactory system, Sensomics, represents reference approach identify and quantitate odorants, well define their sensory...
The volatile fraction of murici, bacuri and sapodilla are here studied because their increasing interest for consumers, abundance production in Brazil, the general demand new flavors aromas. Their profiles were by two High Concentration Capacity Headspace techniques (HCC-HS), Solid Phase Microextraction (HS-SPME) Sorptive Extraction (HSSE), combination with GC–MS. Murici mainly contains esters (38%), carboxylic acids (19%), aldehydes (11%), alcohols (14%), others (13%) sulfur compounds; is...
When bushfires occur near wine regions, vineyards are frequently exposed to environmental smoke, which can negatively affect grapes and wine. For evaluating the severity of smoke exposure, volatile phenols their glycosides commonly used as biomarkers exposure. While critical refining taint diagnostics, few studies have comprehensively assessed compositional impact exposure grapes. In this study, Merlot grapevines were post-véraison, with being sampled both pre-smoke repeatedly post-smoke for...
One approach to controlling type 2 diabetes (T2D) is lower postprandialglucose spikesby slowing down the digestion of carbohydrates and absorption glucose in small intestine. The consumption walnuts associated with a reduced risk chronic diseases such as T2D, suggested be partly due high content (poly)phenols. This study evaluated, for first time, inhibitory effect (poly)phenol-rich walnut extract on human carbohydrate digesting enzymes (salivary pancreatic α-amylases, brush border...
Background and Aims Yeast autolysis is understood to be primarily responsible for giving traditional method sparkling wines complex developed aromas. The contribution from ageing the wine itself, however, less well-established. This study aimed determine of products compounds associated with oxidation in Vitis vinifera L. Chardonnay Pinot Noir over 24 months. Methods Results base were tiraged, or aged without primary lees. Volatile composition analyses (HS-SPME/GC/MS GC/MS/MS) conducted at...
A large set of volatiles (a metabolome) was isolated by SAFE distillation from 25 high priced rums prepared sugar cane juice (SCJ) and 26 manufactured molasses (SCM). The volatile fractions were first analyzed comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-TOF-MS), the "comprehensive template matching fingerprinting" used to extract entire features present in respective compounds. After raw data pretreatment, chemometrics locate marker Following, a...
Recent years have seen an increase in research focusing on the amelioration of apple pomace waste for use food and nutraceutical industries. Much this work has concentrated characterisation polyphenol composition materials to determine their role conferring nutritional health benefits. Although apples contain substantial quantities polymeric procyanidins (condensed tannins), class compounds received limited attention research. This study quantified extracts using a rapid, methyl-cellulose...
The aim of this preliminary study was to identify potential colour components, volatile and sensory attributes that could discriminate Pinot noir wines from five Australian winegrowing regions (Adelaide Hills, Yarra Valley, Mornington Peninsula, Northern Southern Tasmania). analysis consisted the Pivot© Profile method performed by wine professionals. A headspace solid-phase microextraction-gas chromatography-mass spectrometry used quantify multiple compounds, while Modified Somers for...
Untargeted metabolomics experiments for characterizing complex biological samples, conducted with chromatography/mass spectrometry technology, generate large datasets containing very and highly variable information. Many data-processing options are available, however, both commercial open-source solutions data processing have limitations, such as vendor platform exclusivity and/or requiring familiarity diverse programming languages. Data of untargeted metabolite is a particular problem...
