Characteristics of Moisture Content, Swelling, Opacity and Transparency with Addition Chitosan as Edible Films/Coating Base on Casein

Abstract

The objectives of this study was to characterize moisture content, swelling, opacity and transparency of casein solution addition chitosan as edible films/coatings.The effect of chitosan solutions on edible films/coating was chitosan solution 4% of the amount of casein solution. The thickness average value of the casein chitosan edible film is 0.076-0.087 mm. The EFC4 treatmentwas obtained in the lowest moisture content 29.24%, swelling degree 5.48% and opacity 0.078%. High moisture content in the edible film will affect the resistance of the film produced and the packaged product. The lowest average value was found in the EFC4 treatment and EFC2 treatment with a value of transparency 0.63%. The highest concentration of chitosan solutions will tend to decrease the value of moisture content, swelling and opacity edible films/coating.

Chitosan–Sodium Caseinate Composite Edible Film Incorporated with Probiotic Limosilactobacillus fermentum: Physical Properties, Viability, and Antibacterial Properties

“…Hence, the thickness of the CS/NaCas composite film was considered adequate [ 64 ]. The low moisture content and water solubility of the composite films could limit the growth of foodborne pathogens and prevent the disintegration of the edible films when in contact with high humidity or food products with high water activity [ 65 ]. Although the high opacity of CS/NaCas composite films limits the view of the food product, it offers protection for light-sensitive foods [ 66 ].…”

Development of carboxymethyl cellulose–chitosan based antibacterial films incorporating a Persicaria minor Huds. essential oil nanoemulsion

“…Biodegradable edible films with high water content are often susceptible to microbial growth due to the presence of nutritional components. 61 The recommended range for moisture content of bio-based edible films is approximately 16–24%. Hence, the moisture content of the composite film with nanoemulsified P. minor Huds.…”

Transitioning of petroleum-based plastic food packaging to sustainable bio-based alternatives

“…60 Casein, a milk protein, has been explored as a base for edible lms and coatings due to its biodegradable and biocompatible nature. 61 A study by M. W. Apriliyani et al 62 investigated the properties of casein-based edible lms/coatings with the addition of chitosan. The study found that the thickness of the casein-chitosan edible lm ranged between 0.076 and 0.087 mm.…”
