Oranges value chain

Producers source budded orange trees from certified nurseries using disease free budwood and rootstock selected for soil type and climate. South Africa is the worlds second largest citrus exporter and nursery quality determines orchard productivity for the twenty five year tree lifespan.

Orange orchards require integrated pest management for citrus psylla and false codling moth, precise irrigation scheduling and nutrition programmes tailored to phenological stages. Fruit quality for export depends on minimising blemish, achieving target juice content and meeting residue compliance.

Fruit is hand picked with clippers when internal maturity indices are met, regardless of external rind colour. Harvest scheduling across early, mid and late season varieties extends the campaign from April to October, optimising packhouse utilisation.

Oranges are washed, fungicide treated, waxed and electronically graded by size, colour and blemish using machine vision systems. Export pack out rates determine packhouse profitability and high technology grading lines achieve ninety percent accuracy in quality classification.

Non export grade oranges are processed into not from concentrate juice, frozen concentrate and cold pressed essential oil. South African orange juice serves domestic dairy blend and export concentrate markets while essential oil supplies the global fragrance and flavour industry.

Export oranges are shipped under controlled atmosphere via sea freight to Europe, Middle East, Asia and North America. Market access requires compliance with phytosanitary protocols, cold treatment for fruit fly and citrus black spot free certification.
