Water Vapor Permeation

Edible biodegradable films were prepared from amaranth, buckwheat and commercial important corn starches by casting method. Starch, glycerol and carboxymethyl cellulose (CMC) were used to prepare filmogenic starch solutions in potable luke warm water, followed by ultra-sonication for homogenous mixing of the mixed ingredients. After this, heating was applied to starch based slurried solutions until it turned into gel solutions. These filmogenic gel solutions were then dried and films were peeled off and stored in desiccator. Stored films were analyzed for functional properties viz., tensile strength, solubility and water vapor permeation. Amaranth starch based edible biodegradable films presented considerable clarity values however buckwheat starch and corn starch based films exhibited good tensile strength and better solubility values. Developed edible biodegradable films from amaranth starch were analysed for surface structure examination by SEM. Evaluation of surface revealed uniformity, homogeneity with no surface crack on the surface of developed edible biodegradable films.

Water Vapor Permeation

This research aims to study the influences of carvacrol essential oil on the tensile properties and antimicrobial activity of food packages prepared from poly (butylene succinate) (PBS). Overall, the tensile strength and tensile modulus of the PBS film decreased with the addition of carvacrol beyond 4wt%. PBS elongated to a greater extent when carvacrol was employed; the elongation reached its maximum level at 19% when carvacrol was added at 10wt%. The water vapor permeation (WVP) and oxygen permeation (OP) of PBS/carvacrol films tended to increase with increasing carvacrol content due to the vaporization of some carvacrol. Carvacrol was found to effectively inhibit microorganism growth; its antimicrobial activity against S.arious growth was evident when 4wt% of carvacrol was compounded with PBS while that against E.coli growth was found only when 10wt% of carvacrol was employed.
