1. Determination of Ethyl Carbamate in Commercial Sweetened Sugar Cane Spirit by ESI-MS/MS Using Modified QuEChERS and 18-Crown-6/Trifluoroacetic Acid Spiking Additives
A fast, sensitive, and selective direct injection electrospray tandem mass spectrometry (DI ESI MS/MS) method that is able to quantify ethyl carbamate in commercial sweetened sugar cane spirit is described. The preparation method uses a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) with potassium carbonate added to sweetened sugar cane

2. Changes in sugar contents and invertase activity during low temperature storage of various chipping potato cultivars
Abstract Storage of tubers is vital for uninterrupted supply to potato chips/fries industry. Cold storage is preferred to maintain tuber quality. However, prolonged storage at low temperature results in cold induced sweetening (CIS) leading to sugar accumulation and browning of chips. Slowing down the CIS is of economic importance for potato industry. Screen

4. The general and volatile properties and the quality of two newly selected Satsuma clones (11/1 İzmir and 30/ İzmir) grown under Mediterranean ecological conditions
Abstract The general and volatile properties, and the quality of two new Satsuma clones – 11/1 İzmir and 30/İzmir – selected under a Citrus Bud Wood Selection Program, were compared with Owari Satsuma samples grown under Adana ecological conditions. Gas chromatography, mass spectrometry, flame ionization detection (GC/MS/FID) analysis was used in the

5. Feasibility of DLLME for the Extraction and Preconcentration of As and Cd in Sugar for Further Determination by ICP-MS
A method for determining low levels of As and Cd by dispersive liquid-liquid microextraction (DLLME) and inductively coupled plasma mass spectrometry (ICP-MS) was proposed. The following parameters that affect extraction efficiency were investigated: type and volume of extraction solvent (1000 µL acetone), type and volume of dispersive solvent (75 µL carbo

6. Vitamin C Determination by Ultraviolet Spectroscopy and Multiproduct Calibration
In this work the vitamin C was determined in industrialized nectar juices through ultraviolet (UV) spectroscopy and multiproduct multivariate calibration, based on partial least squares (PLS) regression. Since samples with different flavors, sugar content (light or not) were together in the model construction, it can be considered as a multiproduct and, due

7. Characterization of chemical and mineral composition of marolo (Annona crassiflora Mart) during physiological development
Abstract Maroleiro (Annona crassiflora Mart), belonging to the family of Annonaceae is a typical specie of the Cerrado and has occurred in most states. For fruit characteristics “sui generis”, with significant nutritional value. This study aimed to characterize the marolo (Anonna crasiflora Mart) during fruit development, through the evaluation of its pr

8. Desenvolvimento de métodos para estudo de dioxinas presentes na cinza do bagaço da cana-de-açúcar : avaliação do potencial biorremediador de cepas microbianas em compostagem aeróbica / Development of methods for the study of dioxins in sugarcane bagasse ash: evaluation of bioremediation potential of microbial strains in aerobic composting
Sugarcane bagasse ash is a byproduct of sugar and alcohol industry with potential for field application. However, the presence of organic contaminants such as dioxins turns necessary the development of strategies for removal of those pollutants, such as bioremediation. Because of the high toxicity of dioxins, it is wise to develop effective and low risk meth

9. Emissão de gases de efeito estufa na obtenção do etanol de cana-de-açúcar: uma avaliação considerando diferentes cenários tecnológicos em Minas Gerais
This paper presents a greenhouse gas emissions (GHG) assessment of the agricultural and industrial processes of sugar cane ethanol production in Minas Gerais. The assessment was performed by considering different technological scenarios related to the agricultural and industrial processes. The GHG balance takes into account CO2, CH4 and N2O direct emissions

11. Desenvolvimento, reprodutibilidade e validação de um instrumento para quantificar em gramas o consumo de açúcar de amostra da população adulta em Porto Alegre/RS
Evidências indicam a relação entre o consumo excessivo de açúcar pela população mundial e o desenvolvimento de doenças crônicas como cárie, obesidade, diabetes e câncer. Para verificar a relação entre dieta e processo saúde-doença, estudos epidemiológicos utilizam instrumentos válidos, reprodutíveis e confiáveis, sendo o mais utilizado o q

12. Quantification of natural populations of Gluconacetobacter diazotrophicus and Herbaspirillum spp. In sugar cane (Saccharum spp.) Using differente polyclonal antibodies
The species Gluconacetobacterdiazotrophicus, Herbaspirillum seropedicae and H. rubrisubalbicans are endophytic N2-fixing [diazotrophic] bacteria which colonise not only roots, but also the aerial tissue of sugar cane. However, the technique most commonly used to quantify the populations of these microbes in plants is by culturing serial dilutions of macerate
