Abstract
Abstract Studying the causes of postharvest fruit loss is important to avoid reduction of quality and quantity for the consumer due, for example, to the influence of frequent impacts from vibrations during transportation. In this sense, this study evaluates the storage quality of ‘Palmer’ mangoes after being subjected to different simulated road transport vibrations. Vibration was simulated from the analysis of the profile of the frequencies generated in road transport of fruit, determined in a tractor trailer. ‘Palmer’ mangoes stored after vibration stress wereevaluated for: mass loss, absorbance difference index (IAD), peel and pulp browning index (BI), pulp firmness, soluble solids content, and titratable acidity. The development of a vibration machine made it possible to satisfactorily simulate specific vibration frequencies. Vibration stress during simulated transport led to accelerated weight loss, decreased pulp firmness, and peel browning in ‘Palmer’ mangoes.
Highlights
Mango is one of the most produced fruits in the world, accounting for more than half of total tropical fruit production in 2017
Agricultural products are more difficult to manage properly than industrial commodities in terms of logistics because they are highly sensitive to vibration stress during transportation (JUNG et al, 2018)
Qualitative and quantitative changes caused by vibration in fruits have been studied by several researchers in recent years, for fruits such as: watermelon (SHAHBAZI et al, 2010), melon (ZHOU et al, 2015), banana (WASALA et al, 2015), grape (JUNG et al, 2018), apple (SPRINGAEL et al, 2018), and kiwifruit (TABATABAEKOLOOR et al, 2013; WEI et al, 2019)
Summary
Mango is one of the most produced fruits in the world, accounting for more than half of total tropical fruit production in 2017. Springael et al (2018) stressed that transport vibrations are a major contributor to apple perforations and, as a result, losses can be attributed to fungal diseases that enter through injured or perforated tissues and contaminate the fruit. Since vibrations directly influence product quality and integrity, it is essential to gain insight into the magnitude that occurs during transportation. This way, researchers may use information to perform advanced simulation testing, aggregating information for packaging designs (PATERNOSTER et al, 2018) and production outlets. This study evaluates the storage quality of ‘Palmer’ mangoes after being subjected to simulated road transport vibration stress
