Abstract

The TENSILE PROPERTIES, WATER VAPOR PERMEABILITY, OXYGEN PERMEABILITY at different relative humidity (RH), and water solubility of EDIBLE FILM made of PEA STARCH was measured and compared with the most commonly used EDIBLE FILMs. The addition of GLYCEROL into STARCH FILMs made amylase-rich granules swollen and continuously dispersed between amylopectin-rich gels. Tensile strength of pea STARCH FILM decreased when RH increased from 51% to 90%. WATER VAPOR PERMEABILITY was 130 to 150 gr mm/m2.d.kpa. OXYGEN PERMEABILITY of PEA STARCH was very low (<0.5 cm3 mm/m2.d.kpa) below 40% RH, and 1.2 to 1.4 at 45% RH. Water solubility of PEA STARCH was 32.0.Overall pea STARCH FILM possess an excellent oxygen barrier property with extremely high stretchability.
