Multiple retailers have wasted no time putting in orders for goji berries, after the FSA lifted the threat of a ban on the food last week.

One supplier, Tibet Authentic, said buyers from Tesco and Waitrose had ordered berries within hours of the FSA's decision that they were safe to eat.

Nigel Singh from Tibet Authentic said his company's dried goji product was back on shelves, while two other multiples had resurrected discussions on a listing. It was a relief, he said, because the company had just planted 2,500 hectares of goji vines in Tibet.

"There were many nervous moments as we have invested thousands of pounds in NPD and stock to meet demand," Singh said.

The range extends to six products so far but more are slated for launch - all under the Tibet Authentic brand. "We are not selling Tibetan goji berries as an ingredient or as private label because of the high demand and limited supply," he added.
