Bigger, crunchier and longer shelf life blueberries setting the benchmark

South Africa boasts a thriving fruit market with a healthy local demand and enough supply to meet not only local demand but also to export significant volumes to international markets. While many fruits have tapped into local and international demand, the blueberry sector is still seeing significant growth as consumer preferences for the super fruit grows with each passing season. Individual fruit quality will be the biggest factor driving consumer choice, with return purchases most often based on the size, crunch and firmness of each blueberry.

A lot of emphasis has been placed on blueberries with market indicators showing a year-on-year increase in demand. This is backed by research showing that blueberry consumption has reached 650 000 tonnes annually and is set to double to 1.5 million tonnes within the next five years.

Capturing this opportunity, producers of OZblu® blueberries, United Exports, have focused on producing the highest quality fruit by growing their very specific OZblu® series of varieties. Blueberries have seen a massive increase in popularity among consumer, with fruit quality being a key factor in a purchasing decision. Accounting for this, they have implemented a sustainable breeding programme and a precise production, harvesting and post-harvest logistics to protect the fruit along their supply-chain. This allows them to supply fruit near year-round, even months when blueberries are non-seasonal in South Africa like February through April.

“Eating a soft, spoiled blueberry will deter consumers, ruling out chances of a return purchase.”

“Blueberries will always be a competitive market in South Africa and internationally. For any producer to succeed in the blueberry market, focus should be placed on mitigating decay and bruising,” says Roger Horak, executive chairman and founder of United Exports. “Eating a soft, spoiled blueberry will deter consumers, ruling out chances of a return purchase, especially with a variety of other brands on the shelf.”

“We have focused on producing a blueberry that has a longer shelf life, meaning that, as a retailer, you can keep them on your shelves for extended periods of time,” says Horak. “In addition, we have invested extensively in research and development (R&D) to guide our yielding process, to ensure our blueberries retain their superior, crunchy sweetness and full-bodied flavour at home.”

Another factor determining market growth is the seasonality of the fruit. “Our blueberries are grown best in low chill environments and therefore make use of a number of different farming locations around the globe, including South Africa where some of our biggest farms are located. This allows United Exports to produce consistent quality blueberries all year round. The ability to produce identical fruit year-round is important so that we can support retailers with reliable supply and sales consistency through customers returning for high-quality fruit.”
