The biochemical changes in mangoes during ripening affect the fruit composition and quality, making these fruits vulnerable to rapid quality deterioration given their climacteric nature. This study examined the effects of an edible chitosan coating and modified atmosphere packaging (MAP) on room-temperature and cold storage conditions in an effort to enhance the quality of the 'Irwin' mangoes in two experiments. The 100 μL•L -1 and 500 μL•L -1 chitosan coating treatments used here were applied twice as preharvest treatments. Soon after harvest, mangoes were treated with 500 μL•L -1 chitosan postharvest treatment and 80,000 cc and 150,000 cc MAPs along with control and chitosan pre-treated fruits. The fruits in these cases were kept under room-temperature storage conditions in our first experiment. The control and 100 μL•L -1 and 500 μL•L -1 chitosan-preharvest-treated fruits were kept in cold storage at 7°C for 14 days and then exposed to room-temperature conditions as our second experiment. The physicochemical characteristics and respiration rate were subsequently analyzed. Remarkably, MAP types at room temperature were found to affect quality retention and weight maintenance positively compared to the chitosan treatments. However, the physicochemical characteristics were retained during cold storage, and the weight loss% changed moderately after exposure to room-temperature conditions. The soluble solids content, titratable acidity, and respiration rates were not significant, and firmness was decreased significantly only in the control treatment in the days after cold storage. In addition, apparent chromaticity variations could not be obtained from the front and back sides of the fruits. Notably, our first experiment pinpointed MAPs as ideal for room-temperature storage, while our second experiment highlighted the preharvest chitosan treatments as optimal for cold storage. These emerged as the foremost strategies, significantly enhancing the post-harvest quality and extending the shelf life of fully ripe 'Irwin' mangoes.

The 'Irwin' mango is one of the most popular mango cultivars in South Korea, but the fruit perishes quickly after harvesting. Identifying the fruit characteristics is essential to improve the quality after harvest because they vary with the maturity stage. In this study, 'Irwin' mango samples were harvested as a whole and divided into five distinct maturity stage groups depending on the green color proportion of the total fruit skin (S1: Green > 50%, S2: Green 30-50%, S3: Green 20-30%, S4: Green 10-20%, S5: Green 0%). The physicochemical properties, in this case the chromaticity, firmness, soluble solids content (SSC), titratable acidity (TA), ethylene production rate, and respiration rate, were measured soon after harvesting the fruit. Consequently, the S1 and S5 stages showed higher and lower firmness and TA levels, respectively. Moreover, these values were significantly different in each stage. Along with the maturity stage, highest and lowest values in SSC were observed in S5 and S1; correspondingly, and the highest carbon dioxide and ethylene concentrations were observed in stages S5 and S4. With regard to chromaticity, no apparent variations were observed between the front and back sides of the fruit at every color value, though there were significant differences among the stages. By observing all of these quality characteristics, it can be concluded that fruit at the S3 and S4 stages are suitable for storage and are less preferred by consumers at harvest. In this case, the S5 stage is most suitable because the mangoes are at the ready-to-eat stage, more preferred by consumers, and can also be marketed at a higher price.

Hyperspectral imaging (HSI) is a promising tool in chlorophyll quantification, providing a non-invasive method to collect important information for effective crop management. HSI contributes to food security solutions by optimising crop yields. In this study, we presented a custom HSI system specifically designed to provide a quantitative analysis of leaf chlorophyll content (LCC). To ensure precise estimation, significant wavelengths were identified using optimal-band analysis. Our research was centred on two sets of 120 leaf samples sourced from Thailand’s unique Chaew Khing rice variant. The samples were subjected to (i) an analytical LCC assessment and (ii) HSI imaging for spectral reflectance data capture. A linear regression comparison of these datasets revealed that the green (575 ± 2 nm) and near-infrared (788 ± 2 nm) bands were the most outstanding performers. Notably, the green normalised difference vegetation index (GNDVI) was the most reliable during cross-validation (R2=0.78 and RMSE = 2.4 µg∙cm−2), outperforming other examined vegetable indices (VIs), such as the simple ratio (RED/GREEN) and the chlorophyll index. The potential development of a streamlined sensor dependent only on these two wavelengths is a significant outcome of identifying these two optimal bands. This innovation can be seamlessly integrated into farming landscapes or attached to UAVs, allowing real-time monitoring and rapid, targeted N management interventions.
