“…Of the 22 species in the Carica genus, the papaya (Carica papaya L.), native to the American tropics, is the one with the greatest economic importance. It has traditionally been cultivated in different regions of America, Africa, Asia, Australia, countries like the Philippines, and the United States (Hawaii and Florida); and recently in Europe (Honoré et al, 2020). Papaya consumption provides calcium, and vitamin A, exceeding the minimum daily requirements in adults (Karunamoorthi et al, 2014).…”

Objective: To evaluate outstanding and adapted papaya lines derived from selection to conserve desirable characteristics. Design/methodology/approach: 23 lines of the 'Maradol' type were evaluated at Antunez Michoacan, Mexico. Initially, the plants' height, stem circumference, number of leaves, and first fruit height were recorded. During their development, outstanding plants were identified, and their self-pollinating was promoted. In the fruits, their polar and equatorial circumference, shape index, weight, width and pulp firmness, and soluble solids were assessed. Results: The plants' development was different, their variability between lines allowed identifying morphological characteristics of interest. Only 10 lines had this condition. The number of fruits formed over covered flower buds and collected fruits on formed fruits was reduced. The fruits´ characterization, except for their soluble solids, showed differences. Multivariate analysis indicated variability associated with each principal component. Limitations on study/implications: Currently in Mexico, there are few papaya varieties, the 'Maradol' variety being dominant, and vulnerable to phytosanitary problems over time. However, developing varieties and seed production is challenging and the pollination control of the plants necessarily intervenes. Findings/conclusions: Out of 23 assessed papaya lines, only 43.48 % reported outstanding plants. Inside these lines, between 5 and 10 % of the plants were chosen. In the developmental progress from the covered flower buds’ stage to formed and collected fruits, only 28 % of fruits were obtained. The selected lines showed fruit variability.

“…Papaya ( Carica papaya L.) is a fruit from Latin America, from the territorial range that extends from Mexico to the upper Amazon basin, widely cultivated in tropical and subtropical regions of the world. It is recognized for being rich in carotenoids, vitamins A and C, and for its sensory characteristics, such as pleasant aroma, flavor, and texture (Honoré et al, 2020). Because it is a climacteric fruit, papaya continues its physiological activity after being harvested, and it has high perishability (Barros et al, 2019).…”

This study aimed to evaluate the effectiveness of pretreatments on papaya drying behavior and quality parameters. The pretreatment consisted of submerging the samples in ethanol or distilled water for 20 min. The ultrasonic step was conducted in an ultrasonic bath (25 kHz). Samples were dried in an infrared dryer and a convective oven at 60 C. The material pretreated with ultrasound and ethanol and submitted to infrared drying presented the shortest drying time (84 min). The two-term exponential model was the most predictive for the drying data fitting. All dried samples showed water activity values below 0.60. Among the pretreatments performed, the use of ultrasound associated with ethanol was more effective in reducing losses of total phenolics, ascorbic acid, and antioxidant activity of dried papaya when compared to the use of water. Infrared drying of the fruit pretreated with the combination of ultrasound and ethanol resulted in no significant difference from the untreated papaya concerning the evaluated quality parameters. Practical applicationsThe consumption of tropical fruits and their derived products has increased in national and international markets, due to the growing recognition of their nutritional properties and subsequent use in the food industry. The presence of nutrients such as bioactive compounds, demonstrates their potential for use in different sectors, increasing the added value of the cultivar. Thus, this study represents a contribution to society, recognizing and valuing the consumption of fruit, contributing to the nutritional conditions of the population, favoring food and nutritional security, and conservation of the species. It also allows, with the use of pretreatments and different types
