Organic grapes grown in several southern hemisphere countries have completed successful import trials with German supermarkets.

The trials have seen freshness extended to 110 days, according to David Wilkinson, sales director of Longlife Solutions.

"The results using carton liners which create their own atmosphere have so impressed UK supermarkets that they are also studying the results," he said.

"There was no dehydration and just as significantly no SO2 pads were used."
