“…Drying is a critical step in the postharvest process (Fantazzini et al, 2018;Freitas et al, 2018;Osorio et al, 2016). In this context, the main risks that may arise are biological and chemical, and these may result in a product that is unfit for human consumption (Osorio et al, 2016).…”

The defects that drying in concrete yards impose on coffee beans and the search for gourmet coffee production have prompted the emergence of new drying technologies. This work verified the technical and economic feasibility of drying coffee with dehumidified air with a refrigerating capacity of 422,908.7 J s -1 , compatible with static capacity dryers equal to 75 m 3 . Considering the sale price of coffee, the cost of electric energy acquisition, the monthly interest rate and maintenance time, expenses that are equivalent to the depreciation of the concrete yard, a central compound rotational design was considered with 28 tests for the feasibility analysis, including the internal rate of return, net present value and the return on investment. The results showed that in the electric drying units, the dried coffee presents fewer broken and defective beans and has higher retention in a N o . 17 sieve. With a higher beverage quality and a price 12.11% higher, drying with dehydrated air showed a PBD of 2.27 years and a return of US$ 2.49 million. The optimisation results were 98.98% desirable. It was concluded that it is economically feasible to dry coffee with dehydrated air and without using a concrete yard.

“…However, almost all above studies only focused on artificial seed aging. Moreover, previous published research has proved that artificially aged seeds display amplified deterioration in comparison with naturally aged seeds (Petruzzelli and Carella, 1983;Giurizatto et al, 2012;Fantazzini et al, 2018) and are associated with a higher prediction accuracy. In addition, all these researches are destructive, and limited research has been conducted for naturally aged seed deterioration.…”

The viability status of seeds before sowing is important to farmers as it allows them to make yield predictions. Monitoring the seed quality in a rapid and nondestructive manner may create a perfect solution, especially for industrial sorting applications. However, current offline laboratory-based strategies employed for the monitoring of seed viability are time-consuming and thus cannot satisfy industrial needs where there is a substantial number of seeds to be analyzed. In this study, we describe a prototype online near-infrared (NIR) hyperspectral imaging system that can be used for the rapid detection of seed viability. A wavelength range of 900–1700 nm was employed to obtain spectral images of three different varieties of naturally aged watermelon seed samples. The partial least square discriminant analysis (PLS-DA) model was employed for real-time viability prediction for seed samples moving through a conveyor unit at a speed of 49 mm/sec. A suction unit was further incorporated to develop the online system and it was programmatically controlled to separate the detected viable seeds from nonviable ones. For an external validation sample set showed classification accuracy levels of 91.8%, 80.7%, and 77.8% in relation to viability for the three varieties of watermelon seed with healthy seedling growth. The regression coefficients of the classification model distinguished some chemical differences in viable and nonviable seed which was verified by the chromatographic analysis after the detection of the proposed online system. The results demonstrated that the developed online system with the viability prediction model has the potential to be used in the seed industry for the quality monitoring of seeds.

“…Few references appear in the scientific literature on using the accelerated aging test to evaluate the physiological conditions of Coffea arabica L. seed lots. Pertel et al (2003) and Fantazzini et al (2018) worked with the accelerated aging test at the temperature of 42°C and different exposure times for coffee seeds. They observed that seed deterioration occurred over long periods of exposure, indicating that other ambient conditions within the aging chamber should be investigated.…”

The vigor tests are important tools used in the internal quality control by the seed companies. The accelerated aging test is a sensitive method for assessing the vigor of seed lots, as well as for estimating their storage potential. However, for coffee seeds there is little information about its use and efficiency.The objective of this study was to investigate methods of the accelerated aging test suitable for Coffea arabica L. seeds. Two studies were carried out. In the first, different temperatures (42°C, 44°C, and 46°C) and exposure times (0, 24, 48, 72, 96, 120, 144, 168, and 192 h) were investigated for the accelerated aging test. In the second, the best combinations of temperatures and exposure times were tested on coffee seeds from five different cultivars at temperatures of 44 and 46 ºC at times of 24, 48, 72, and 96 h of incubation. After each aging period, the water content of the seeds was determined, and physiological quality was evaluated by the germination test. The temperature of 42°C leads to slow deterioration of the seeds and is not recommended for evaluation of Coffea arabica L. seed vigor at the exposure times from 24 to 192 h tested here. The accelerated aging test, carried out at a temperature of 44ºC for 72 hours or at 46ºC for 48 hours, allows the Coffea arabica seed lots to be separated into different vigor levels.
