Film extends shelf-life for fruits and vegetables
Significant shelf-life extension of between two and five days has been reported for fruit and vegetables using an innovative new method of wrapping.
Retail trials using Sirane’s Sira-Flex™ Resolve® have reported four additional days shelf-life with potatoes and equally significant results with other fruit and vegetables. Sirane’s Sira-Flex™ Resolve® is a new, unique film which has been developed to have the optimum balance between humidity control and O2 and CO2 permeability. The permeability is temperature dependant so that the perfect atmosphere is maintained inside the pack even if the storage temperature is variable. The film is a natural bio-polymer made from plants. It is sustainable and fully compostable. The permeability is controlled by the property of the film itself. Due to the unique structure of the film material, the permeability to humidity, O2 and CO2 is different in each case. This has allowed Sirane’s team of scientists to balance the permeability of each component to achieve the optimum result. Shelf-life is a particular issue within the international export business. Fruits and vegetables are shipped all around the world, many are grown in the hotter parts of the world—Spain, North Africa, Turkey, the Middle East, South and Central America.They are shipped to the UK, Northern Europe, Russia, the US and elsewhere for consumption, often with only a few days shelf-life left when they arrive at their destination. In conclusion, Sirane’s Sira-Flex™ Resolve® could
• Improve the quality, taste and texture of the food for the consumer.
• Reduce food waste and associated costs
• Reduce processing and shipping costs
• Bring new export markets within range of population centres
