Antimicrobial edible films made from clove essential oil play a role in reducing, inhibiting, or slowing the growth of bacteria that may be existed in food packaging or packaging materials to extend the shelf life of packaged foods. This study aims to produce whey and clove oil films with film thickness, elongation, tensile strength, water vapor transmission rate, optical properties, antimicrobial properties of clove oil, and its inhibition against pathogenic microbes. The physical and antimicrobial characteristics of edible film were investigated using an experimental method in a completely randomized design with four treatments. The treatment used different concentrations of clove oil (C0: 0% clove essential oil, C1: 5% clove essential oil, C2: 10% clove essential oil, and C3: 15% clove essential oil). The percentage value of elongation and microbial inhibitory activity were significantly affected (p<0.01) by the concentration of clove essential oil. Based on all variables, 10% clove essential oil concentration is the best treatment with a thickness of 0.035 mm, elongation of 78%, tensile strength of 8.82 N, water vapor transmission rate of 7.80 g.mm-2.day-1, and inhibitions of E. coli and S. aureus resulted in high rates. The results conclude that the addition of clove essential oil has a promising potential to improve the antimicrobial properties of whey edible film composites. The use of clove essential oil at the level of 10% is the best treatment.

The research aims to observe the effect of konjac glucomannan and different types of plasticizers on the microstructure of whey film. The microstructure of whey film was investigated using an experimental method. The research was conducted in descriptive methods with two treatments.The treatment used konjac glucomannan concentration (P4= 2.5 %; P7= 3 %) and different types of plasticizers (C1= glycerol 30 %; polyethylene glycol 30 %). The results showed that the combination of whey and konjac glucomannan had an effect on the microstructure of the film. The addition of konjac glucomannan concentration, 30 % glycerol, and 30 % PEG plasticizers gave microstructural characteristics with good whey film surface. The microstructure of this film was determined during the heating, drying process and the contribution of the gel from konjac glucomannan to the whey film structure. A more homogeneous edible film microstructure was obtained using a 2.5 % concentration of KGM with the use of 30 % glycerol plasticizer where the distribution of konjac glucomannan was mixed into the whey protein matrix evenly (homogeneous).
