According to David Edwards, the new packaging can imitate natural membranes that hold food such as grape skins.
Till date, David Edwards and his team have developed a tomato membrane containing gazpacho soup; an orange membrane containing orange juice; a grape-like membrane holding wine; and a chocolate membrane holding hot chocolate.
Currently, the team is working on developing a prototype bottle that features an eggshell-like hard coating in addition to the membrane that could be eaten whole or peeled off.
In a similar effort, Indiana-based MonoSol is developing water-soluble packaging for food, while Leicester-based Pepceuticals is creating an edible coating for fresh meat.
