“…Various studies report similar values of color measurement to those found in this research, concluding that the carotenoid content like β-carotene, 9-cisviolaxanthin and lutein, is correlated positively (r 2 > 0.9) to the measurements of these parameters (Ayour et al, 2016). Thus, the studied mango varieties could have important bioactive pigment content.…”

Mango is one of the tropical fruits of greater production and consumption in the world, and a rich source of bioactive compounds, with various functional properties such as antioxidant activity. In Colombia, mango's market is very broad and diverse. However, there are very few studies that determined the content of bioactive secondary metabolites. The objective of this study was to evaluated the content of different metabolites like Mangiferin, carotenoids, tannins, and the antioxidant capacity by oxygen radical absorbance capacity (ORAC) methodology of six cultivars from the Colombian Caribbean region, with total carotenoid values ranging from 24.67 to 196.15 mg of β-carotene/100 g dry pulp; 84.30 to 161.49 mg Catequine eq./100 g dry pulp for the content of condensed tannins, and 91.80 to 259.23 mg/100 g dry pulp for mangiferin content. The ORAC methodology showed important antioxidant activity results, such as the Chancleta variety with the highest value (2163.78 μmol Trolox/100 g dry pulp). In conclusion, the evaluated mango varieties had promising results as functional food of high nutraceutical value, being Chancleta, Criollo and Jobo varieties, the fruits with highest content in bioactive compounds that expressed the best antioxidant activity.

“…Apricot species present the largest variability in fruit color of Prunus species, ranging from white (‘Moniqui’) and orange (‘Goldrich’) to fruits largely covered with a strong red blush such as ‘Orange Red’. Intervarietal crosses have been performed between different contrasted cultivars, and recombinant hybrids have been obtained to study their physical and physiological behavior together with the genomic expression of their target genes [ 42 , 59 , 61 , 76 , 77 , 78 ].…”

“…Carotenoids are responsible for yellow/orange skin ground color and flesh color in apricot fruits. In apricots, a relationship between skin and flesh color with carotenoid content was demonstrated [ 76 , 87 ], and a non-destructive method to determine the content of carotenoids, β-carotene, and pro-vitamin A based on the flesh and skin color of the edible portion developed [ 77 ]. Carotenoids supplied to the human diet have important health benefits such as protective activity against several human cancers, cardiovascular diseases, and degenerative diseases [ 88 , 89 , 90 , 91 , 92 , 93 , 94 ].…”

In plants, fruit ripening is a coordinated developmental process that requires the change in expression of hundreds to thousands of genes to modify many biochemical and physiological signal cascades such as carbohydrate and organic acid metabolism, cell wall restructuring, ethylene production, stress response, and organoleptic compound formation. In Prunus species (including peaches, apricots, plums, and cherries), fruit ripening leads to the breakdown of complex carbohydrates into sugars, fruit firmness reductions (softening by cell wall degradation and cuticle properties alteration), color changes (loss of green color by chlorophylls degradation and increase in non-photosynthetic pigments like anthocyanins and carotenoids), acidity decreases, and aroma increases (the production and release of organic volatile compounds). Actually, the level of information of molecular events at the transcriptional, biochemical, hormonal, and metabolite levels underlying ripening in Prunus fruits has increased considerably. However, we still poorly understand the molecular switch that occurs during the transition from unripe to ripe fruits. The objective of this review was to analyze of the molecular bases of fruit quality in Prunus species through an integrated metabolic, genomic, transcriptomic, and epigenetic approach to better understand the molecular switch involved in the ripening process with important consequences from a breeding point of view.

“…These color changes may be due in large part to the degradation of the pigments (chlorophylls) in the fruit peel (Ayour, Sagar, Alfeddy, Taourirte, & Benichou, 2016). It is important to mention that there are no reports of the use of the CIELab color space for the determination of the fruit's color.…”

The cuajilote (Parmentiera edulis D.C.) tree produces fibrous fruits with a high content of lignocellulosic compounds. However, this fruit and their fibers have been scarcely studied. For this reason, an integral study of their cellular architecture, physicochemical, micromechanical, and structural properties in two maturity stages were carried out. Physicochemical tests, light, confocal and electron microscopy, microindentation, and X‐ray diffraction were used for the characterization of fruit and their fibers. Chemical analysis showed that the unripe fruits have the highest cellulose content (42.17%), but in ripe fruit the cellulose content decreases (32.76%) while lignin content increases from 35.26 to 40.79%, caused by the lignification of the sclerenchyma fibers. Microstructural and micromechanical studies in the different regions of the fruit provided relevant information about its cellular architecture, distribution of lignocellulosic compounds and its role in the micromechanical properties of their fibers. The thickening cell wall of sclerenchyma fibers was caused by the cellular lignification of the ripe fruits. According to the physicochemical and structural studies, cuajilote fibers are comparable to other fibers obtained from crops rich in lignocellulosic compounds. The current study provided new knowledge about the cellular architecture of fruit and criteria for selecting the ripening stage adequate for the extraction of cellulose or lignin. Furthermore, information regarding the micromechanical properties of their fibers and which structural arrangement could be more convenient for mechanical reinforcement of biodegradable materials was obtained.
