Brazilian organic sugarcane spirits: Physicochemical and chromatographic profile
Provedor de dados: 124
Autores: Duarte,Felipe Cimino; Cardoso,Maria das Graças; Santiago,Wilder Douglas; Machado,Ana Maria Resende; Nelson,David Lee.
ABSTRACT There has been a growing demand for products from organic agriculture for the food market. Brazil leads the production of sugarcane spirits and produces about 1.6 billion liters/year. New technologies have been sought throughout the supply chain to improve production, and organic raw material has been used in the production of sugar cane for the production of beverages. This study aimed to define the physicochemical and chromatographic profiles of eleven organic sugarcane spirits samples from various Brazilian states. The secondary components and contaminants were identified and quantified through physicochemical analyses, HPLC and gas chromatography (GC). A significant percentage of the organic sugarcane spirits samples contained concentrations...

Carbonyl compounds in wine: factors related to presence and toxic effects
Provedor de dados: 65
Autores: Lago,Laura Oliveira; Welke,Juliane Elisa.
ABSTRACT: The objective of this study was to review technological and toxicological factors related to presence of carbonyl compounds found in wines, including acetaldehyde, formaldehyde, acrolein, ethyl carbamate (EC) and furfural. Acetaldehyde and formaldehyde may be formed through the ethanol and methanol oxidation, respectively. Acrolein may arise as a thermal degradation product of glycerol, amino acids, carbohydrates and triglycerides or by metabolic activity of microorganisms. In addition, acrolein and furfural are formed during wood combustion; therefore, these aldehydes may be present in raw materials due to the environmental contamination. Furfural is also a product of the Maillard reaction formed from sugars and amino acids, while ethyl...
