Quantificação de contaminantes em aguardentes de cana/cachaças de alambique e de coluna

In the present study aimed to characterize and quantify four contaminants (ethyl carbamate, 2,3-butanedione, furfural and 5-hydroxymethylfurfural) present in alembic cachaça and industrial. Were collected forty-four samples of cachaça in the southern regions, the Midwest, southeast of Minas Gerais and São Paulo state, and subsequently subjected to physical, chemical and chromatographic analyzes. The physicochemical analyzes were performed according to the methodology described by the Ministry of Agriculture, Livestock and Supply (MAPA). The ethyl carbamate, 2,3-butanedione, furfuaral and 5 hydroxymethylfurfural were characterized and quantified by high-performance liquid chromatography (HPLC). The results of the ethyl carbamate analysis, it was found that both samples showed column cachaças outside the standards required by law, with the values 245.31 235.53 L-1 ug and none of the liquor samples alembic showed concentration greater than 210.0 ug L-1 , and the method is very sensitive to low limits of detection and quantification. In determining 2,3-butanedione, it was revealed that the column cachaças showed higher levels of contaminants when compared to cachaça alembic. In the quantification of furfural and 5-hydroxymethylfurfural was developed and validated analytical methods employed to high-performance liquid chromatography (HPLC) with DAD detector. Samples column cachaças showed higher values than the limit established by Brazilian legislation and ranged from 7.00 to 5.63 mg / 100 ml of anhydrous alcohol over the alembic cachaça.

Caracterização, gênese e uso de latossolos sob cerrado no município de Rio Paranaíba - MG

The main objective of this research was to study the morphological, physical, chemical, mineralogical and geomorphic characteristics of two soil types in the Rio Paranaíba área of Minas Gerais. Using descriptions based on current methods, the soil profile study was carried out in two trenches both two meters in depth. The landscape of this region consists of an extensive, flat plain where the Red Yellow Latosol is found. In addition, the Dusky Red Latosol is distributed on slopes between the basin of Parana-São Francisco and the plateau. Chemical analysis show that the Red Yellow Latosol presents an extremely low natural fertility and the high amounts of gibbsite indicates a highly advanced degree of weathering for this soil. Mecanization is difficult in the Dusky Red Latosol due to the steep relief. Thus, Dusky Red Latosol could be put to better use as land for pastures and perennial crops taking the necessary care to prevent erosion. The soils were classified respectively as Typic Acrustox and Acrustox according to the Soil Survey Staff (67) and were categorized as Dystrophic Red Yellow Latosol of a clayish texture, flat relief, with clayish substratum sediments and Dystrophic Dusky Red Latosol, of clayish texture, high relief, undulant substratum, with and volcanic tuffs in agreement with the criteria proposed by Bennema and Camargo (11) for the Brasilian Classification.

Ácidos orgânicos de baixa massa molar em solos e materiais orgânicos

Determination of organic acids in soils and organic materials is important due to the important role they play in improving the soil's physical, chemical and microbiological conditions. This study identified and quantified low molecular weight organic acids (LMWOA) in soils (dystroferric Red Latosol, dystrophic Red-Yellow Latosol and Quartzarenic Neosol) and organic materials (cow, pig, chicken, quail and horse manures, sawdust, coconut fiber, pine bark, coffee husks, biochar, organic substrate, sewage sludges 1 and 2, garbage compost, pig slurry compost). The following acids were identified: acetic, citric, D-malic, formic, fumaric, maleic, malonic, oxalic, quinic, shikimic, succinic and tartaric.
