“…Penchaiya and Tijskens [32] discovered that during low-temperature storage of mango 'Nam dok mai si thong', the a* and b* values increased, while the L* and hue values decreased, which aligns with the results of the current study. Another primary factor influencing mango fruit quality during ripening is water loss in the fruit caused by respiration and dehydration [1], which reduces fruit weight and causes the skin of the fruit to shrink due to decreased cell wall pressure. As the mango fruit ripens, structural carbohydrates also undergo chemical transformation, with pectin, a gelling sugar, contributing to the firmness loss of the fruit [31].…”

“…PLS is a precisely calibrated algorithm for investigating the association between prediction and response parameters. It provides a potent multivariate calibration method where the variations from both the predictive and response parameters are simultaneously extracted and used for correlating the regression model [1], using input data to compute the prediction models [19,57]. A few previous studies have employed the use of PLS to determine relationships between quality attributes in fresh produce.…”

“…Changes in luminescence are driven by post-harvest degradation of mango pigments, especially chlorophyll and carotenoids, that contribute to green and yellow-orange colouration in mango fruit [31], alongside the generation of melanins arising from oxidation of phenol [31,51,52]. Most of the weight loss is caused by metabolic processes that convert precursors to water as a byproduct, such as cellular respiration and dehydration [1,30], where ethylene is the primary actuator [54]. In addition, biological reactions impact the quantity of reactants and yields, which can be evaluated with pH and TSS [33] and may be due to the transformation of organic acids [31] and polysaccharides [5,31].…”

Evaluation of Markers Associated with Physiological and Biochemical Traits during Storage of ‘Nam Dok Mai Si Thong’ Mango Fruits

Mango ‘Nam dok mai si thong’ is in high demand worldwide, displaying desirable attributes which include a particularly sweet flavour and visually appealing appearance. Physiological and biochemical changes that occur in the fruit post-harvest are key factors in determining fruit quality and, consequently, predicted shelf life. In order to understand which post-harvest markers play crucial roles during the ripening process, as well as those which are a consequence of disease infection and physical damage caused by essential oil vapour, partial least squares (PLS) correlation models were used. During storage, physiochemical (percent weight loss, peel colour, firmness, pH, and peel electrolyte leakage) and biochemical (titratable acidity, total soluble solids, total phenolic compounds, total flavonoid compounds, antioxidants, total sugar, and reducing sugar content) parameters, as well as near-infrared (NIR) spectra, were monitored and correlated with visual post-harvest physiological responses. The majority of analysed markers displayed distinct relationships with the ripening process of mangoes, where for non-destructive parameters (R2 = 0.86), lightness (L*) and b* value were notably significant, and for destructive parameters (R2 = 0.79), pH and total soluble solids were notably significant. Similarly, the same markers were also correlated with physical damage and post-harvest mango disease infection severity, possibly through polysaccharide deformation and activation of browning-related enzymes. NIR imaging results also revealed the absorbent regions involved in biochemical alterations (water and enzymes; absorbance at 1170 nm, 1400–1500 nm, and 2150–2250 nm) that pertain to the fruit’s quality. The findings from this work provide an initial step towards the development and assessment of quality measures for ‘Nam dok mai si thong’ mango.

Temperature Difference in Loading Area (Tarmac) during Handling of Air Freight Operations and Distance of Production Area Affects Quality of Fresh Mango Fruits (Mangifera indica L. ‘Nam Dok Mai Si Thong’)

et al. 2022

Mango (Mangifera indica L.) ‘Nam Dok Mai Si Thong’ is an important cultivar for export from Thailand. Export mainly takes place via air transport, but for about 2 h at the loading area (tarmac), unit loading devices (ULDs) are exposed to ambient environmental conditions. In this research, the effects of different temperature conditions at the loading area (tarmac) and the distance of the production area from the tarmac on the quality of fresh mango fruits were studied. The treatments included three temperature conditions for 2 h (simulated handling in tarmac)—constant temperature (20 °C), non-insulated or insulated and exposed to sun—and two distances of the tarmac from the production area—short distance (i.e., transport occurring 53 h after harvest) and long distance (i.e., transport occurring 70 h after harvest). The temperature variation in the boxes exposed to the sun was greater in the non-insulated than in the insulated boxes, but this effect was more pronounced in fruit from the short-distance production area (28.1 °C insulated and 36.9 °C non-insulated) than in fruit from the long-distance production area (34.2 °C insulated and 38 °C non-insulated). Insulation and short distance increased the shelf life, decreased weight loss, delayed the decrease in average firmness and rupture force, etc. The insulation of mango fruit boxes mitigates the deleterious effect of exposure to 2 h of direct sun by reducing the increase in temperature, thus improving the shelf life and quality of mango fruit.
