Mango quality is affected by thermal storage conditions. Therefore, it is important to use cooling techniques and their monitoring to maintain desirable properties in the fruit. The objective of this study was to evaluate the effects of commercial rapid cooling programs on the quality of 'Rosa' mango. Mangoes were distributed on different horizontal positions of six pallets. All pallets were put through two rapid cooling times, three pallets for 120 minutes and three pallets for 240 minutes. Subsequently, the fruits were stored in a cold chamber for 7 and 14 days, followed by an evaluation of shelf life for 3 days at 20°C. Experimental design was in randomized blocks with three replicates, with one pallet per replicate. The weight, pH, and skin color of the fruit were assessed. According to the results, fruits closer to the air inlet in the packages showed the highest cooling rates. After storage and shelf life, quality parameters were not significantly affected by the rapid cooling programs. In conclusion, the 120-minute program can be satisfactorily adopted for the rapid cooling process of the 'Rosa' mango, considering the reduction of energy costs and the reduction of the dwell time of the fruit in the cold chamber.

All models were calculated using OriginPro 8.5 (OriginLab, Massachusetts, USA, 2018) and Microfit® (Siqueira, Carvalho, Mendes, & Shiosaki, 2014). The coefficient of determination (R²) and the Root mean square error (RMSE) were used to determine the proper fit.…”

Studying new microbial sources and evaluating the growth kinetics behavior to predict large-scale production become essential. Besides, research with low-cost culture media has gained interest due to the need to decrease enzyme production costs. The literature concerning the use of macromycetes as a source of amylases, and applying mathematical models to predict their behavior is scarce. In this study, four growth kinetics in different compositions of culture media were carried out: two of them using different concentrations of Low-Grade Flour (LGF), one wheat mill by-product and two synthetic ones. In the kinetics mathematical models were used to evaluate the bioprocesses and their scaling feasibility. Mathematical models, such as modified Logistic, modified Gompertz, Baranyi, and Roberts, and modified Luedeking-Piret, were applied to predict mycelial growth, enzyme production, and substrate consumption. The results showed the model’s capability to predict mycelial growth (biomass) and substrate consumption (starch concentration). On the other hand, the mathematical models efficiently describe only the maximum enzymatic activity (α-amylase), not the process's other parameters, because of the complexity and diversity of biomolecules synthesized by Coprinus comatus. The wheat mill by-product was efficient as an ingredient in the culture media composition. Furthermore, it was concluded that B2 formulation (culture medium with 48.5 g/L of LGF) is the batch with the highest potential for the α-amylase production from C. comatus and the expansion of this process on an industrial scale. This study is important and valid for the scientific community since modeling studies for macromycetes are scarce in the literature.
