“…Last but not least, the pattern of changes observed for quality parameters agreed with previous reports [ 9 , 32 , 33 ]. Colour parameters related with ripening, such as the increase in a * and decrease in Hue angle, changed in a similar way as described by other authors [ 9 , 32 ] and paralleled the changes found in carotenoids. The sharp increase in red colour pigments, such as carotenoids, were reported between stages 2 and 5 of ripening (breaker to light red), together with a decrease in the L * value [ 33 ].…”

Post-Harvest Use of Ultraviolet Light (UV) and Light Emitting Diode (LED) to Enhance Bioactive Compounds in Refrigerated Tomatoes

Different strategies have been developed to increase the concentration of bioactive compounds in tomatoes during post-harvest, with ultraviolet light (UV) and light emitting diodes (LEDs) being interesting tools. The aim of this study was to evaluate the effect of ultraviolet (UVA at 366 nm and UVC at 254 nm) pre-treatment (1 kJ/m2) and red–blue LED light (25.4 µmol/m2/s) on the concentration of carotenoids, (poly)phenols and hydrophilic/lipophilic antioxidant capacity during 7 days of refrigeration storage of green tomatoes (Solanum lycopersicum L.) cultivar “Raf”. In addition, special attention was paid to quality parameters (weight loss, colour, acidity, soluble solids and ripening index). Tomatoes exposed to LED light at 6 °C for 7 days increased up to three times the total carotenoids content (mainly β-carotene and E-lycopene) compared to tomatoes refrigerated in the dark, while UV treatments alone did not significantly affect the carotenoid content. Besides, exposure to LEDs increased the hydrophilic and lipophilic antioxidant capacity of tomatoes by 30%, without affecting phenolic contents. Thus, LED treatments alone during refrigerated storage fostered ripening and improved the nutritional value of tomatoes, without compromising quality parameters. Further studies must be carried out to evaluate the impact on sensory attributes and consumer acceptance.

“…Furthermore, analysis of the total color change parameter (ΔE*ab) depicted a highly significant difference (P < 0.05) between red (21.95–24.47) and yellow (7.72–26.26) or orange (3.13–7.59) flesh types as noted for a* or b* color components (Table 2). During the ripening stages of tomato fruit, both the meso and exocarp fruit tissues exhibited both decreased L* and b* values, and increased a* values in the fully ripened red color fruits [46]. This suggests that the observed color space characteristics of inbred watermelon lines with red flesh color are consistent with those in reported studies.…”

Whole genome resequencing of watermelons to identify single nucleotide polymorphisms related to flesh color and lycopene content

et al. 2019

Cultivated watermelon (Citrullus lanatus) is one of the most important food crops in the Cucurbitaceae family. Diversification after domestication has led cultivated watermelons to exhibit diverse fruit flesh colors, including red, yellow, and orange. Recently, there has been increased interest in red-fleshed watermelons because they contain the antioxidant cis-isomeric lycopene. We performed whole genome resequencing (WGRS) of 24 watermelons with different flesh colors to identify single-nucleotide polymorphisms (SNPs) related to high lycopene content. The resequencing data revealed 203,894–279,412 SNPs from read mapping between inbred lines and the 97103 reference genome. In total, 295,065 filtered SNPs were identified, which had an average polymorphism information content of 0.297. Most of these SNPs were intergenic (90.1%) and possessed a transversion (Tv) rate of 31.64%. Overall, 2,369 SNPs were chosen at 0.5 Mb physical intervals to analyze genetic diversity across the 24 inbred lines. A neighbor-joining dendrogram and principal coordinate analysis (PCA) based on the 2,369 SNPs revealed that the 24 inbred lines could be grouped into high and low lycopene-type watermelons. In addition, we analyzed SNPs that could discriminate high lycopene content, red-fleshed watermelon from low lycopene, yellow or orange watermelon inbred lines. For validation, 19 SNPs (designated as WMHL1–19) were chosen randomly, and cleavage amplified polymorphic sequence (CAPS) markers were designed. Genotyping of the above 24 lines and 12 additional commercial cultivars using WMHL1–19 CAPS markers resulted in match rates of over 0.92 for most validated markers in correlation with the flesh color phenotypes. Our results provide valuable genomic information regarding the high lycopene content phenotype of red-fleshed cultivated watermelons, and the identified SNPs will be useful for the development of molecular markers in the marker-assisted breeding of watermelons with high lycopene content.

“…According to the literature, changes in the skin color of tomatoes can be observed, changing from green (negative values of a*) to red (positive values of a*), in which the fruit ripens. This ripening process can occur due to the degradation of chlorophyll and lycopene synthesis in exocarp pigments 48,49 . The ethylene oxidation can be seen in the literature regarding quality postharvest maintenance and shelf‐life extension of the climacteric fruit and vegetables.…”

This study is reported as the first demonstration of the use of solution blow spun mats in a Nano‐sachet system containing a humidity absorber hydrogel and a paraffin wax tablet impregnated with potassium permanganate (KMnO4) for exogenous ethylene (ex‐C2H4) oxidation, in order to delay fruit ripening. The tomatoes quality during storage time was characterized by gas chromatography (GC) (ethylene concentration and CO2 emission analysis—respiration rate), and colorimetry (green/red color parameter). Ex‐C2H4 production over storage time was reduced for the Nano‐sachet system when compared to the control system. Color changes, from 72 to 120 h, displayed fruit still predominantly green in the Nano‐Sachet system (a* from −9.1 to −6.9), color transition green‐red in the TNT‐sachet (−7.5 to −0.3) and increased red color fruit in the control system (−6.1 to 3.7). This work suggests that nanofibrous mats can be used as a packaging system with the ability to protect, potentialize ethylene oxidation and extend climacteric fruits and vegetables quality in shelf life.
