Active Edible Films Based on Modified Corn Starch for Food Applications

摘要

Modified corn starches ACLS and OS as major components of the structural matrix of FS are able to form EFs with good visual and mechanical properties, representing an excellent alternative for developing tailor-made films or coatings for specific food products. The use of BW nano-emulsion as a hydrophobic agent at 1 % (w/v) concentration showed lower WVP and provided good solubility properties to EFs, which is important to increase the shelf life of minimally processed fruits. Use of the natural antimicrobials LAE and natamycin incorporated into active EFs achieved complete inhibition of B. cinerea, the most common deteriorative fungus of strawberries. Strawberries coated with active EFs showed brighter appearance and lower weight loss than the control treatment.
