“…Similarly, postharvest SA and PUT applications retarded color development in different fruits (Ahmad & Ali, 2019;Banda et al, 2014;Koyuncu et al, 2019;Malik et al, 2003).

To extend the postharvest storage life of broccoli samples (Brassica oleracea L. var. italica), an exogenous application of citric acid (CA), salicylic acid (SA), and putrescine (PUT) was tested in multiple combinations (0.5 and 1 mM) at 4 ± 0.5°C and 90 ± 5% relative humidity (RH) for 21 days (d). The weight loss (WL), respiration rate (RR), total soluble solids (TSS), pH, color (L*, a*, b*, chroma, and hue angle), proximate and mineral contents, phenolic and flavonoid contents, and other biochemical properties of the treated and untreated broccoli samples were evaluated throughout the storage duration. The lowest WL was observed when exposed to 0.5 mM of PUT. 1 mM CA and PUT treatments were affected by RR, depending on storage conditions. The lowest TSS content was observed in broccoli samples treated with 0.5 mM CA among all treatments. The chroma value of the samples was preserved by the 0.5 mM SA treatment. The most abundant element in broccoli samples was potassium in the control application, followed by a 1 mM SA treatment. In addition, the protein content was the highest in the 1 mM PUT treatment. The highest vitamin C was determined in the 1 mM CA treatment, and the most abundant vanillic acid was found in broccoli exposed to the 0.5 mM and treatment. Glucose content was determined at the lowest level in the 0.5 mM SA treatment, while higher increases occurred in other treatments. In terms of these findings, 1 mM CA, 1 mM SA, and 1 mM PUT delay WL, RR, and color degradation and prolong the storage life of broccoli samples stored at 4 ± 0.5°C. It was concluded that the biochemical content, fresh weight, and green color of broccoli samples throughout postharvest and storage can be maintained longer by exogenous application of these natural compounds. Therefore, we recommend 1 mM PUT and 1 mM CA treatments to maintain the quality of broccoli by minimizing losses in morphological properties, mineral, and biochemical compositions during postharvest storage.

Super-atmospheric O 2 has been shown to affect respiration rate (RR), but no model describing its effect on RR for pomegranate arils has been reported. This study investigated the effects of four different gas compositions (5 kPa O 2 , 10 kPa CO 2 and 85 kPa N 2 ; 10 kPa O 2 , 5 kPa CO 2 and 85 kPa N 2 ; 70 kPa O 2 , 10 kPa CO 2 and 20 kPa N 2 ; and air) on RR of pomegranate arils (cv. Wonderful) stored at 5°C. Michaelis-Menten enzyme kinetics models were used to investigate the effect of CO 2 inhibition on O 2 consumption rate. Respiratory quotient was used to determine fermentation threshold. The O 2 consumption rate increased from 0.87 to 2.81 mL/kg h, with increase in O 2 concentration from 5 kPa to 70 kPa. All enzyme kinetics model parameters adequately described the influence of gas concentration on aril RR with correlation coefficient (R 2 adj = 81-91%). Modelado de cinética enzimática para evaluar el impacto de altas concentraciones de CO 2 y de concentraciones súper-atmosféricas de O 2 en la frecuencia respiratoria de arilos de granada RESUMEN Se ha demostrado que el O 2 súper-atmosférico incide en la frecuencia respiratoria (FR); sin embargo, no existe ningún modelo que describa su efecto en la FR de los arilos de granada. El presente estudio analizó los efectos que cuatro composiciones diferentes de gas (5 kPa O 2 , 10 kPa CO 2 y 85 kPa N 2 ; 10 kPa O 2 , 5 kPa CO 2 y 85 kPa N 2 ; 70 kPa O 2 , 10 kPa CO 2 y 20 kPa N 2 ; y aire) tuvieron en la FR de arilos de granada (cv. Wonderful) almacenados a 5°C. Así, para investigar el efecto de inhibición que el CO 2 produce en la tasa de consumo de O 2 se utilizaron modelos de cinética enzimática de Michaelis-Menten (MM), mientras que para determinar el límite de fermentación se empleó el cociente respiratorio (CR). Se constató que el aumento de la concentración de O 2 de 5 kPa a 70 kPa produjo un incremento de la tasa de consumo de O 2 , que se elevó de 0.87 a 2.81 mL/kg h. Todos los parámetros del modelado de cinética enzimática describen adecuadamente la influencia de las concentraciones de gas en la FR de arilos de granada, con el coeficiente de correlación (R 2 adj = 81-91%).
