“…Most sugarcane quality attributes demonstrated significant (p < 0.05) Pearson's correlations surpassing 0.90, except for fiber, which exhibited non-significant correlations (Figure A1 in the Appendix A). This is expected since all this quality variables are related to sucrose content, and other soluble solids, such as reducing sugars and non-sugars, account for less than 2% of the total physicochemical constitution of sugarcane [41,47].…”

In-field quality prediction in agricultural products is mainly based on near-infrared spectroscopy (NIR). However, initiatives applied to sugarcane quality are only observed under laboratory-controlled conditions. This study proposed a framework for NIR spectroscopy sensing to measure sugarcane quality during a real harvest operation. A platform was built to support the system composed of the NIR sensor and external lighting on the elevator of a sugarcane harvester. Real-time data were acquired in commercial fields. Georeferenced samples were collected for calibration, validation, and adjustment of the multivariate models by partial least squares (PLS) regression. In addition, subsamples of defibrated cane were NIR-acquired for the development of calibration transfer models by piecewise direct standardization (PDS). The method allowed the adjustment of the spectra collected in real time to predict the quality properties of soluble solids content (Brix), apparent sucrose in juice (Pol), fiber, cane Pol, and total recoverable sugar (TRS). The results of the relative mean square error of prediction (RRMSEP) were from 1.80 to 2.14%, and the ratio of interquartile performance (RPIQ) was from 1.79 to 2.46. The PLS-PDS models were applied to data acquired in real-time, allowing estimation of quality properties and identification of the existence of spatial variability in quality. The results showed that it is possible to monitor the spatial variability of quality properties in sugarcane in the field. Future studies with a broader range of quality attribute values and the evaluation of different configurations for sensing devices, calibration methods, and data processing are needed. The findings of this research will enable a valuable spatial information layer for the sugarcane industry, whether for agronomic decision-making, industrial operational planning, or financial management between sugar mills and suppliers.

“…Estima-se que a cana-de-açúcar seja cultivada globalmente em uma área superior a 26 milhões de hectares. O Brasil é o maior produtor do mundo, seguido pela Índia e China (Costa et al, 2021). As áreas cultivadas com cana-de-açúcar no Brasil estão concentradas em grande parte na Região Centro-Sul, com destaque para o estado de São Paulo, maior produtor nacional dessa cultura (Tabela 1).…”

“…A cana-de-açúcar é uma cultura de relevante importância econômica para o agronegócio brasileiro, sendo o Brasil o maior produtor dessa cultura no mundo (Costa et al, 2021). A produção brasileira corresponde a aproximadamente 38% da produção global dessa cultura, e o país é ainda responsável por 50% das exportações mundiais de açúcar.…”

O Brasil se destaca internacionalmente como o maior produtor de cana-de-açúcar, uma cultura chave para o agronegócio nacional. Nessa cultura, a ocorrência de plantas daninhas pode ocasionar graves prejuízos, motivo pelo qual seu controle se faz necessário. Para isso, se faz uso principalmente do controle químico à base de herbicidas. Entretanto, a exposição dos trabalhadores rurais a herbicidas tem sido associada à ocorrência de diversos problemas de saúde nesses indivíduos. Nesse sentido, este trabalho busca levantar, por meio de levantamento bibliográfico, a importância da cultura da cana-de-açúcar e o uso de herbicidas nessas culturas, os riscos aos quais os trabalhadores rurais estão expostos e quais agravos à saúde estão sujeitos pelo manuseio e aplicação desse produtos, bem como qual é a legislação que ampara esses trabalhadores e quais os desafios para garantir a efetividade dessa legislação. Para tanto, conduziu-se uma pesquisa bibliográfica utilizando o método de revisão integrativa. Os efeitos deletérios da exposição de trabalhadores à herbicidas são bem reportados na literatura para diferentes princípios ativos. O Brasil tem uma densa legislação vigente voltada para segurança do trabalho, o que, teoricamente, tornaria o manuseio e a aplicação de herbicidas e outros defensivos agrícolas uma atividade de baixo risco para a saúde do trabalhador rural. Todavia, infelizmente, esse não é o panorama visto em muitas regiões agrícolas do país, principalmente pelo não uso de Equipamentos de Proteção Individual (EPIs). Ações como treinamentos periódicos para esses profissionais se fazem necessárias e um maior rigor na fiscalização de uso também deve ser implementado. **Palavras-Chave**: Contaminação; Equipamentos de proteção individual; Exposição.

Quality assessment of fruits, vegetables, or beverages involves classifying the products according to the quality traits such as, appearance, texture, flavor, sugar content. The measurement of sugar content, or Brix, as it is commonly known, is an essential part of the quality analysis of the agricultural products and alcoholic beverages. The Brix monitoring of fruit and vegetables by destructive methods includes sensory assessment involving sensory panels, instruments such as refractometer, hydrometer, and liquid chromatography. However, these techniques are manual, time-consuming, and most importantly, the fruits or vegetables are damaged during testing. On the other hand, the traditional sample-based methods involve manual sample collection of the liquid from the tank in fruit/vegetable juice making and in wineries or breweries. Labour ineffectiveness can be a significant drawback of such methods. This review presents recent developments in different destructive and nondestructive Brix measurement techniques focused on fruits, vegetables, and beverages. It is concluded that while there exist a variety of methods and instruments for Brix measurement, traits such as promptness and low cost of analysis, minimal sample preparation, and environmental friendliness are still among the prime requirements of the industry.
