Abstract This paper provides, for the first time, an overview of different aspects related to quality coffee beans and their volatile fractions: species/cultivars, geographic origins, bean defects, types beverages, processing, roasting, storage. In other words, it concerns complex relation between seeds components. It is 48 articles considering 6 its aromatic fraction. The greatest numbers published papers concerned “species cultivars” “defective seeds,” both with 11 cited, followed by...
Lipids are major coffee components, and changes in their composition during storage may contribute to loss of sensorial quality. In this study, the triacylglycerols (TAG) free fatty acids (FFA) Coffea arabica seeds roasted two color degrees (light medium dark medium) were evaluated for 6 months, under temperature (5 °C 25 °C) atmosphere (air N2) conditions. For first time, hydrolysis TAG fraction was observed coffee, with increases FFA, after 1 month storage, from 0.4 93.5 mg/100 g...
Due to their health benefits, there is growing interest in the production and use of carotenoids from natural sources, e.g. microalgae. To date, only Haematococcus pluvialis Dunaliella, that accumulate, respectively, astaxanthin β-carotene large quantities, are grown commercially. However, also being focused on other xanthophylls, such as (all-E)-fucoxanthin characterized by anti-obesity anti-carcinogenic effects. In this regard, rigorous chemical analytical techniques following preparative...
Due to Brazil?s significant role as a major global corn producer and the impact of pesticide accumulation in sediments on health aquatic ecosystems, this study addresses need for simplified method assess residues both matrices, sediments. A modified QuEChERS combined with gas chromatography-mass spectrometry, was validated analysis seven common pesticides Paran? State, Brazil: desisopropylatrazine (DIA), deethylatrazine (DEA), diazinon, methyl parathion, pirimiphos methyl, malathion, ethyl....
ROBUSTA RAW AND ROASTED COFFEES.The decaffeinated coffee market has been expanding increasingly in the last years.During decaffeination, aroma precursors and bioactive compounds may be extracted.In present study we evaluate changes chemical composition of C. arabica canephora produced by decaffeination using dichloromethane.A significant change both species was observed, with differences between degrees roasting.Major were observed sucrose, protein trigonelline contents after...
Negroamaro is an autochthonous wine grape variety of Southern Italy, which becoming very important for the Italian market. The aroma primary affected by chemical composition grapes, can be influenced also agronomic practices such as soil management. In this study, free and bound characterization was performed gas chromatography–mass spectrometry analyses, influence two managements (cover cropping tillage) evaluated. A total 40 volatile compounds were observed in samples. Alcohols (55.7...
This study aimed to assess the impact of two soil managements and training systems on yield wine aroma compounds Negroamaro variety grown in a warm climate region (southern Italy). Cover crop (CC) tillage (ST) as management, whilst bilateral Guyot (BG) monolateral (MG) were compared. Free bound volatile fractions evaluated by GC-MS. ST CC well BG MG significantly affected parameters. In particular, was higher than MG, respectively; moreover, it found be positively influenced interaction...
VOLATILE cOmpOsITION OF INTRINsIc DEFEcTIVE cOFFEE BEANs By Gc/ms-hEADspAcE.About 20% of Brazilian raw coffee production is considered inappropriate for exportation.consequently, these beans are incorporated to good quality in the market.This by-product industry called pVA due presence black (p), green (V) and sour (A) defective which known contribute considerably cup decrease.Data on volatile composition scarce.In this study, we evaluated immature, black-immature, compared beans.potential...
Phenolic compounds have a strong influence on the quality and authenticity of grapes, they been main objective several studies due to its importance structure, flavour color wines. These determined along time by different instrumental techniques combining physical chemical methodologies. Nowadays, innovative analytical systems, based spectroscopy, ability analyse complex samples. systems are increasing wine industry since fast, accurate eco-friendly methods. This work reviews current...
