“…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.

“…For fast evaluation of the seed storability, various methods have been used to accelerate seed deterioration [5] . Controlled deterioration (CD) is a method of simulating stress conditions that will result in increasing respiration rates and depletion of reserves, culminating in degenerative changes in seed metabolism and eventual deterioration [6] . A systematic proteomic investigation of Arabidopsis seed ageing demonstrates that CD is a suitable way for predicting seed storability and deterioration, and reveals comparable molecular processes in both CD and naturally aged seeds [5] .…”
