1. Volatile Metabolomics from Cashew Leaves: Assessment of Resistance Biomarkers Associated with Black Mold (Pilgeriella anacardii Arx & Müller)
Black mold, a disease caused by the fungus Pilgeriella anacardii Arx & Müller, affects cashews (Anacardium occidentale). Some cashew clones are more resistant to the pathogen; however, little is known about the chemical profile responsible for this trait. The investigation of volatile organic compounds (VOCs) from leaves of dwarf cashew clones resistant (BR

2. Odor-contributing volatile compounds of a new Brazilian tabasco pepper cultivar analyzed by HS-SPME-GC-MS and HS-SPME-GC-O/FID
Abstract The cultivar BRS Avai was originated from recurrent phenotypic selection in the original American cultivar Tabasco Macllhenny™, used in the worldly famous Tabasco pepper (Capsicum frutescens L.) sauce. The determination of the aroma profile of this new cultivar could reveal important qualitative descriptors that will help in future crosses and in

3. DETERMINATION OF CHEMICAL PROFILE OF Eugenia dysenterica ICE CREAM USING PS-MS AND HS-SPME/GC-MS
The incorporation of Cerrado fruits in food products such as ice cream has many advantages because it represents a source of nutrients and bioactive compounds. Given the demand for less laborious methods to analyze food, the paper spray ionization mass spectrometry technique was applied for the first time for a rapid characterization of the chemical componen

4. The effects of adding garlic (Allium sativum L.) on the volatile composition and quality properties of yogurt
Abstract In this study, the effects of adding garlic (Allium sativum L.) of different origins on the volatile composition and quality properties of yogurt were investigated on day 1, 7 and 14 of storage. The addition of garlic did not cause a decrease in the total specific microorganism count (>107) in yogurt samples, and it led to a significant decrease in

5. VOLATILE COMPOUNDS IN CACHAÇAS OBTAINED FROM THREE SUGARCANE VARIETIES CULTIVATED UNDER THE MANAGEMENTS: ORGANIC, CONVENTIONAL AND WITHOUT FERTILIZATION
The volatile compounds present in cachaça can derive from the raw material used in the production of the beverage, from the fermentative process, from distillation or aging. The aim of the research was to evaluate the volatile compounds, in the cachaças from stills produced with different sugarcane varieties, under the organic and conventional managements.

6. ESSENTIAL OIL OF CURCUMA LONGA L. RHIZOMES CHEMICAL COMPOSITION, YIELD VARIATION AND STABILITY
Turmeric (Curcuma longa L.) is a medicinal plant that is cultivated worldwide. This study was conducted to evaluate the variability in the percentage and the chemical composition of volatile oils from 12 turmeric samples. Rhizomes of the turmeric plant were collected from three different producers in the Brazilian like savanna (Cerrado) habitat in the state

7. Mango (Mangifera indica) Aroma Discriminate Cultivars and Ripeness Stages
Mango (Mangifera indica) has many nutritional attributes that stimulate its consumption, such as sweetness, balanced acidity and intense fruity aroma. In this study, it was demonstrated that both the variety and ripening stage have a significant impact on the aroma of mango. The volatile compound profile of “Tommy Atkins”, “palmer”, “espada” and

8. Characterization of volatiles in red- and white-fleshed loquat (Eriobotrya japonica) fruits by electronic nose and headspace solid-phase microextraction with gas chromatography-mass spectrometry
Abstract Aroma differences are generally sensed in white- and red-fleshed loquats. Here, volatile compounds in four white- and three red-fleshed loquat varieties were investigated by headspace solid-phase microextraction and combined analysis of electronic nose (e-nose) and gas chromatography-mass spectrometry (GC-MS). In total, 83 volatile compounds were id
