In order to make harvesting table olives profitable, mechanical harvesting has become an absolute necessity. Many small Andalusian producers face structural and financial constraints in implementing the mechanisation of harvesting and, as a consequence, the fruit is still harvested manually. A manual inverted umbrella (MIU), initially designed for harvesting oil olives, was evaluated in order to determine the extent in which this device can optimise the harvesting without jeopardising the fruit quality. Simultaneously, the effects of a diluted lye treatment, applied to prevent the proliferation of brown spots caused by bruising during mechanical harvesting, was also studied. The quality of the harvested fruit was evaluated after complete fermentation. The results indicate that when no diluted lye treatment was applied, using the MIU resulted in a slightly inferior fruit quality. However, when the amount of heavily damaged fruit is taken as a standard, the MIU presented results comparable to those obtained by manual harvesting. The MIU does, therefore, offer small producers an efficient alternative, given that manual harvesting costs are up to three times higher than the costs incurred during MIU harvesting.

Table Olive

Table olives are traditionally harvested manually. However, a shortage of agricultural workers and high labor costs have prompted the search for mechanical solutions. Mechanical harvesting of four cultivars of green table olive—Manzanilla, Hojiblanca, Souri, and Nabali Mouhassan—was compared with manual picking in terms of harvest efficiency and final product quality. Mechanical harvest methods were: trunk shaking with and without simultaneous rod beating and with and without the application of an abscission agent. Olives were immersed in a diluted NaOH solution in the field, transported to the processing plant, and subjected to commercial procedures processing. Application of an abscission agent resulted in inconsistent fruit-detachment force values and did not affect harvest efficiency. Mechanical harvest with rod beating reached high harvest efficiencies of 80% to 95%, whereas the elimination of rod beating significantly reduced harvest efficiency. Final product quality of the mechanically harvested ‘Hojiblanca’, ‘Souri’. and ‘Nabali Mouhassan’ was similar to that of their manually picked counterparts, whereas that of cv. Manzanilla was inferior to those picked manually. High harvest efficiencies can be obtained using trunk shakers and simultaneous rod beating but final product quality of the mechanically harvested olives depends on variety. In some, mechanical harvesting can be used safely; in others such as cv. Manzanilla, further work is required to obtain a good-quality final product.

Main Determinants

Fruit quality is certainly influenced by biotic and abiotic factors, and a main quality attribute is the external appearance of the fruit. Various possible agronomical approaches are able to regulate the fruit microenvironment and, consequently, improve fruit quality and market value. Among these, fruit bagging has recently become an integral part of fruits’ domestic and export markets in countries such as Japan, China, Korea Australia and the USA because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. Despite increasing global importance, the development of suitable bagging materials and, above all, their use in the field is quite laborious, so that serious efforts are required to enhance and standardize bagging material according to the need of the crops/fruits. This review provides information about the effects of bagging technique on the fruit aspect and texture, which are the main determinants of consumer choice.
