Chilean research company SaviaGrapes released last month a new device they say can extend the shelf-life of grapes by 30-50 days by preventing breakdown of the fruit.
The plastic device is clipped on to the stem of a bunch of grapes immediately after harvesting, and contains a gel similar to natural vine sap.
The gel – which includes carbohydrates, amino acids, water and mineral salts – effectively keeps the grapes alive, rather than simply slowing the fruits’ decomposition, according to SaviaGrapes.
Companies including Wal-Mart, Chiquita and Dole attended two product launches for the device last month in the US.
Manuel José Alcaíno, SaviaGrapes’ partner company Decofruit’s president, said the device mimics vine conditions.
“The grapes retain their flavour, texture and quality virtually intact, like they’re freshly picked, for an extended period of time. The main effect is the green colour of the stem, but other positive effects include less shatter, less sunken cup stems, and less decay.”
