Drying kinetics of yellow mombin (Spondias mombin L.) epicarp

Abstract

Yellow mombin (Spondias mombin L.) fruits have relevant characteristics for industrialization and exhibit a pleasant aroma and sour-sweet taste, with significant amounts of vitamin A and carotenoids in their epicarp. The objective was to fit different mathematical models to the experimental data, using as criteria to select the best model - the Akaike Information Criteria (AIC) and Schwarz’s Bayesian Information Criteria (BIC), as well as to evaluate the effective diffusion coefficient and to determine the activation energy for yellow mombin epicarp submitted to different drying conditions. The experiment was carried out at the Instituto Federal de Educação, Ciência e Tecnologia Goiano, Brazil The epicarp of yellow mombin fruits with initial moisture content of 2.89 (dry basis, d.b.) were submitted to drying at temperatures of 40, 50, 60 and 70 °C until final moisture contents of 0.11, 0.10, 0.09 and 0.08 (d.b.), respectively. The Midilli model showed the best fit to the experimental data obtained. The choice of the model was confirmed by the AIC and BIC criteria. The increase of the drying temperature promoted increase in the effective diffusion coefficient, and the activation energy of the process was 21.50 kJ mol-1.

Drying kinetics of araticum (Annona crassiflora) epicarp

“…Recently, several researchers have updated, based on the AIC and BIC criteria to select with greater accuracy, the best mathematical model to represent the drying curves for different agricultural products (Gomes et al, 2018;Quequeto et al, 2019;Souza et al, 2019;Bastos et al, 2019;Pinheiro et al, 2020;Siqueira et al, 2020).…”

“…The literature reports values of activation energy for various agricultural products: 21.50 kJ mol -1 for yellow mombin epicarp (Pinheiro et al, 2020), 29.18 kJ mol -1 for biofortified sweet potato (Souza et al, 2019) and 34.72 kJ mol -1 for passion fruit peel (Bezerra et al, 2015). According to Zogzas et al (1996), the activation energy for agricultural products ranges from 12.7 to 110 kJ mol -1 .…”

Germinated seeds of three Cucurbita varieties: Physical characteristics, minerals profile, and drying behavior

“…found effective diffusivity values of 6.98 Â 10 À11 m 2 /s in samples of dry cowpea by direct exposure to the sun combined with night drying in a heat accumulator dryer, and 6.84 Â 10 À11 m 2 /s for the control samples, which were left on the laboratory bench at night. In contrast, lower values were observed byPinheiro, Oliveira, Ferreira Junior, and Resende (2020), in drying cajá epicarp, at temperatures from 40 to 70 C, with effective diffusivities ranged from 0.57 Â 10 À11 to 1.24 Â Â 10 À11 m 2 /s.…”

Fitting of mathematical models in the drying of araticum (Annona crassiflora) seeds

“…Based on the correspondence between the experimental values and those estimated by the model, there was a satisfactory fit of the model to the data obtained during the drying of araticum seeds under all conditions, as confirmed by the AIC and BIC. Recently, several researchers have updated, based on the AIC and BIC criteria to select with greater accuracy, the best mathematical model to represent the drying curves for different agricultural products (Bastos et al, 2019;Gomes et al, 2018;Pinheiro et al, 2020;Quequeto et al, 2019;Souza et al, 2019).…”
