Fruit appearance is often the impetus driving initial purchase by consumers, however customer satisfaction and subsequent repeat purchases are based upon the taste quality of the fruit. Most of the mangoes (Mangifera indicia L.) marketed fresh in the USA are imported from other countries. Due to the long distances over which mangoes are shipped and the handling environment of the international produce supply chain, the fruit are harvested and transported at the mature green stage, when they are still firm enough to arrive in the USA with minimal losses due to transportation and handling. Flavor quality in mangoes is primarily related to cultivar, maturity stage at harvest, and postharvest handling methods.
While a number of objective maturity indices have been developed, many (such as flesh color) are destructive and none are universally used by the industry. As a result, it is common for shipments of mangoes into the USA to contain immature fruit. The marketing of immature mangoes is detrimental to repeat sales as they will not ripen properly or develop good flavor. This research was conducted to evaluate the potential of three nondestructive instrumental techniques for their ability to provide reliable means of distinguishing between immature and mature hard green mangoes. Of the three nondestructive methods, NIR interactance measurements to predict the dry matter and soluble solids content were the most effective at maturity classification, correctly classifying 86% of hard green ‘Tommy Atkins’ mangoes into mature and immature categories. While the electronic nose could correctly classify 68% of the fruit, it required several days of ripening before optimal performance could be obtained.
