Mauritius Grants Protected Geographical Indication Status to Rodrigues Lime After 12-Year Wait

Rodrigues Lime

Port Louis, The Gulf Observer: In a historic milestone following a 12-year wait, the Rodrigues lime — known locally as limon Rodrig — has officially been granted Protected Geographical Indication (PGI) status.

The official certification was conferred last Monday, 24 August, by the Ministry of Foreign Affairs in Mauritius. Louis Ange Perrine, Commissioner for Agriculture, was present to receive the award, marking a decisive shift for the agro-industry of the island.

“It has been 12 years since we made this request,” Commissioner Perrine said. “After 12 years of waiting, it is a historic moment for Rodrigues. After limes, it will be the turn of our honey, red beans and small chillies to be awarded PGI status.”

Valid for ten years, the PGI label is set to significantly enhance the value of the small citrus fruit on export markets. It also introduces strict regulatory measures for local artisans and commercial enterprises: no product made from or containing limon Rodrig may henceforth be marketed without bearing the official PGI label.

To ensure compliance, businesses must submit an authorisation request to the Commission of Agriculture, which will detail the exact procedure for affected producers and entrepreneurs. A moratorium period is expected to be considered to allow retailers to clear existing stock currently on shelves without the new label.

Strict Technical Specifications

The designation applies exclusively to the whole fresh fruit of the botanical species Citrus aurantifolia L. (Mexican lime) grown entirely on the island of Rodrigues. Cultivated completely free of chemical inputs, the crop relies entirely on natural rainfall for irrigation, with all agricultural practices — from planting to harvest — performed manually by local farmers and family labour.

Distinct physical and chemical attributes separate the fruit from other limes, particularly those found across the wider Mascarene Islands.

  • Appearance and texture: Round, ovoid or elliptical in shape, with a diameter of between 25 mm and 50 mm. Its smooth skin ranges from a uniform light green at maturity (for fresh consumption) to full yellow (for processing). The skin is greasy to the touch with a pronounced sour fragrance, indicating a high essential oil content.
  • Juice and flavour: The juicy green pulp contains seeds and offers high juice yields — a minimum of 20 per cent of total fruit weight for mature green limes and 30 per cent for yellow limes. The highly aromatic juice carries a persistent sour taste with lemongrass notes.
  • Chemical profile: The fruit contains over 47 per cent limonene. Vitamin C levels reach 390 ppm in mature green limes and 480 ppm in yellow limes. Titratable acidity ranges from 8.32 per cent (green) to 9.22 per cent (yellow), while total soluble solids/sugars range from 7.7° Brix (green) to 8.5° Brix (yellow).

The production of limon Rodrig is dispersed across the entire island, ranging from sea level up to an altitude of 300 metres. Experts attribute the lime’s unique quality to Rodrigues’ relatively drier climate, its volcanic and limestone soils, its geographical isolation within the Indian Ocean, traditional organic practices, and the deep-rooted cultural reputation of lime production on the island.
