Summary

Use of Nature Seal (TM) 1020, a cellulose-based edible coating, as carrier of antioxidants, acidulants and preservatives prolonged the storage life of cut apple and potato by about 1 week when stored in overwrapped trays at 4 deg C. Adjustment of coating pH to 2.5 gave optimal control of browning and microbial populations. Addition of soy protein to the original cellulose-based Nature Seal formulations reduced coating permeability to oxygen and water vapour. Cellulose formulations with protein were effective in controlling weight loss, especially when the pH of the formulation was raised above the isoelectric point, of the protein.
