Export of fresh table grapes and pome fruit from South Africa to non-traditional markets such as Israel, USA, China, and Mexico constitutes approximately less than 1 % of the total export volume of table grapes (SATI, 2007) or pome fruit (PPECB, 2007). With an increase in fresh fruit supply to traditional markets mainly from South American countries, it is imperative that alternative markets be developed.

Viljoen, H., 2011, ‘Effect of gamma irradiation as a mitigation treatment on storage quality of plums’, SA Fruit Journal, 10(4), 73-75.

 

Export of fruit from South Africa to certain countries, such as the USA, requires a mandatory coldsterilisation period of 22 days at -0.55°C or below, to disinfest fruit from phytosanitary pests, such as Mediterranean fruit fly. Since certain plum cultivars require a dual-temperature regime to maintain postharvest quality during cold storage, it is not possible to export such cultivars to markets with strict phytosanitary regulations.

Forelle, an attractive bi-colour pear, has been grown in Germany since 1670. With such a long history of cultivation, one wonders why the harvesting and storage of this cultivar is still so challenging…

De Kock, V.A., Khumalo, P. & Davids, J., Jooste, M. 2006, ‘Forced-air cooling’, SA Fruit Journal 5(3), 17.

 

Plums exported from South Africa to overseas markets require effective cold storage management to ensure optimum maintenance of fruit quality. Plums should be placed under cooling within a few hours of harvest, and typically, the fruit is forced-air cooled to -0.5°C. The rate of forced-air cooling (FAC) prior to cold storage has been found to influence the development of internal disorders in some plum cultivars (Jooste and Khumalo, 2004).

De Kock, A., 2011, ‘Flesh firmness utilising a Penetrometer with a 6-mm plunger as a harvest maturity parameter for apricots’, SA Fruit Journal, 10(5), 79-81.

 

Skin colour and the percentage wring are currently used as parameters for determining optimum harvest maturity of apricots in South Africa. Skin colour is determined using an industry colour chart, and the wring test is performed by cutting the fruit along the suture and twisting the halves in opposite directions to enable visual inspection of the stone. The fruit is regarded as wrung if no flesh adheres to the visible part of the stone. Despite use of these maturity indices, large variations in harvest maturity occur across years, farms and orchards, often resulting in inconsistent apricot quality in the market place.

In the fresh produce export industry, fruit temperature is monitored using thermocouples, which are inserted in a standardised position in pallet stacks, for ascertaining the temperature of produce during forced-air cooling (FAC) and the subsequent cold chain.
