What is Berrisys LITE?
Berrisys LITE is a laminated plastic, dual release, sulfur dioxide generating sheet designed to protect loose packed (bulk) blueberries or open top punnet packed blueberries.
Berrisys LITE was designed and manufactured on the same principles as Uvasys. Its function is to protect blueberries that are transported and stored, from post-harvest fungal decay, particularly the devastation caused by Botrytis cinerea fungus (grey mould / mold).
How does it work?
- Berrisys LITE consists of a sequence of laminated plastic membranes, each bonded by a wax layer containing precise concentrations, and particle sizes, of Sodium Metabisulfite: Na2S2O5.
- The top and middle plastic membranes sandwich the Slow Release layer.
- The middle and bottom membranes sandwich the Fast Release layer.
- The Fast Release sterilizes the surface of the blueberries, by releasing a large enough dose of sulphur dioxide over a 24 to 48 hour period to kill and eliminate any actively growing Botrytis cinerea fungal spores.
- The Slow Release layer emits a low, continual dose of sulphur dioxide gas, concentrated enough to inhibit any superficial latent or inherent Botrytis cinerea spores from growing, but also low enough to ensure sulfite residues within the blueberries remain safely below the legal limit of 10 ppm. Infection which occurred at flowering could still develop but will be contained to the affected berry.
- The quantity of SO2 emitted is critical to the efficacy of the product as an excessive release of SO2 can cause bleaching while insufficient release may not prevent the development of Botrytis.
