Título:  Monitoring the physicochemical degradation of coconut water using ESI-FT-ICR MS.

Conteúdo:  Fresh and aged coconut water (CW) samples were introduced directly into the electrospray ionisation (ESI) source, and were combined with the Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) technique to characterise in situ chemical compounds produced during natural ageing (from 0 to 15 days) at room temperature (23 °C). The ESI-FT-ICR MS readings were acquired and the data were correlated to conventional methodologies: pH, total titratable acidity (TA), total soluble solids, microbial analyses, and ultraviolet visibility (UV?vis) spectroscopy analysis. In general, the pH and TA values changed after 3 days of storage making the CW unsuitable for consumption. The ESI(?)-FT-ICR data also showed a clear and evident change in the chemical profile of CW after 3 days of ageing in the m/z 150?250 and 350?450 regions. Initially, the relative intensity of the natural markers (the m/z 215 and 377 ions?sugar molecules) decreases as a function of ageing time, with the last marker disappearing after 3 days of ageing. New chemical species were then identified such as: citric (m/z 191), galacturonic (m/z 193), gluconic (m/z 195), and saccharic (m/z 209) acids. ESI(?)-FT-ICR MS is a powerful tool to predict the physicochemical properties of CW, such as the pH and TA, where species such as fructose, glucose, sucrose, and gluconic acid can be used as natural markers to monitor the quality of the fruits.

Título:  A mixed model to multiple harvest-location trials applied to genomic prediction in Coffea canephora.
Ano de publicação:  2017

Idioma:  Inglês
Conteúdo:  Abstract Genomic selection (GS) has been studied in several crops to increase the rates of genetic gain and reduce the length of breeding cycles. Despite its relevance, there are only a modest number of reports applied to the genus Coffea. Effective implementation depends on the ability to consider genomic models, which correctly represent breeding scenario in which the species are inserted. Coffee experimentation, in general, is represented by evaluations in multiple locations and harvests to understand the interaction and predict the performance of untested genotypes. Therefore, the main objective of this study was to investigate GS models suitable for use in Coffea canephora. An expansion of traditional GBLUP was considered and genomic analysis was performed using a genotyping-bysequencing (GBS) approach, showed good potential to be used in coffee breeding programs. Interactions were modeled using the multiplicative mixed model theory, which is commonly used in multi-environment trials (MET) analysis in perennial crops. The effectiveness of the method used was compared with other genetic models in terms of goodnessof-fit statistics and prediction accuracy. Different scenarios that mimic coffee breeding were used in the cross-validation process. The method used had the lowest AIC and BIC values and, consequently, the best fit. In terms of predictive ability, the incorporation of the MET modeling showed higher accuracy (on average 10?17% higher) and lower prediction errors ... Mostrar Tudo
