Description :
DigInfoTV presented Aura Pack, developed by Belle Green Wise, a film that helps to keep vegetables fresh. The freshness-preserving effect is achieved by controlling evaporation through molecular activity, and controlling excess respiration.
"Aura Pack has three features. The first concerns the fact that vegetables have a water content of at least 90%. As long as water isn't lost, they stay crisp and fresh. If vegetables are wrapped in this film, it's hard for water to evaporate. The second feature of this film is, it controls respiration. Like people, vegetables take in oxygen and release CO2. The more congenial the environment, the more stable this process is, making it harder for vegetables to get bruised. In a pack, it's possible to create a congenial environment. The third feature of Aura Pack is, it resists condensation, so it's hard for moisture to form. As I mentioned earlier, if vegetables don't lose water, it's hard for water droplets to form on the film."
Until now, films have included stay-fresh measures such as holes. But Aura Pack works on vegetables through its special processing, making it hard for them to lose water.
"In supermarkets, especially after last year's earthquake, the summer temperature setting was increased from 25 to 28 C degrees. A three-degree increase in temperature makes vegetables very prone to bruising. Vegetables that had been sold loose can be given a longer shelf life by wrapping them in this stay-fresh film. Discard rates are reduced substantially. So retailers are using Aura Pack as well."
Leafy vegetables like spinach can be kept fresh for 2-3 days longer with Aura Pack. In long-term storage, persimmons sealed in the film last for 3-4 months. It can also be used to adjust shipments, so persimmons picked in November can be eaten in April.
"Aura Pack is useful when exporting value-added fruits. Shipping by sea takes at least two weeks to Asia and 3-4 weeks to Europe. Fruits and vegetables are inevitably vulnerable. So, using this stay-fresh film makes it possible to export them by sea at low cost."
