Does the Hydrogel: Oleogel Ratio Affect the Physicochemical Properties of Gelatin–Beeswax Bioplastic Films?
AI summary Read the abstract
This study found that varying the ratio of hydrogel to oleogel in gelatin-beeswax bioplastic films significantly affects their thickness, solubility, tensile strength, and water vapor transmission. The optimized formulations offer a biodegradable alternative to conventional plastic food packaging, which contributes to microplastic pollution as it degrades.
Plastic waste from packaging poses a serious environmental problem due to its persistence and contribution to microplastic formation. Bigels, composed of hydrogel and oleogel, have emerged as an innovative approach to eco-friendly food packaging. This study aimed to analyze the effect of varying hydrogel-oleogel ratios on the physicochemical properties of bigel-based bioplastic films for food packaging applications. An experimental design was employed using a Completely Randomized Design (CRD) with four treatments and five replications. Data were analyzed using ANOVA, and when significant (p<0.05) or highly significant (p<0.01) differences were detected, further testing was conducted using Duncan's Multiple Range Test (DMRT). The treatments were Hydrogel: Oleogel ratios, consisted of T1 (90 :10), T2 (80 :20), T3 (70 :30) and T4 (60 :40) respectively. The findings indicated that the optimal ratio was achieved in T1 (90:10). Detailed results included solubility (21.133%), syneresis (81.186%), water-holding capacity (77.174%), moisture content (7.549%), thermal properties (TGA/DTG) more stable and optical microscopy which shows small and relatively homogeneous droplets. Overall, the results demonstrated that T1 (90:10) provided the most favorable physicochemical characteristics of bigels bioplastic films for food packaging applications. These findings highlight formulation-dependent structural mechanisms that advance the use of gelatin-beeswax gels for food packaging.

Food Packaging Materials with Special Reference to Biopolymers-Properties and Applications
AI summary Read the abstract
This review examines food packaging materials with emphasis on biodegradable polymers such as PHA, PLA, and starch-based plastics, finding they outperform conventional non-biodegradable plastics in environmental impact while maintaining protective functionality. Replacing petroleum-based packaging with biodegradable alternatives directly reduces the source of microplastic contamination entering food systems and the broader environment.
Selluloosan liukeneminen ja regenerointi: Kohti muovittomia kalvoja systemaattisen suunnittelun avulla
AI summary Read the abstract
Systematic design of regenerated cellulose films using non-derivatizing solvents achieved up to 50% higher strength and improved barrier properties through hemicellulose retention, pulp blending, and plasticizer optimization, producing biodegradable films suitable for demanding packaging applications. Replacing fossil-based plastic films with genuinely biodegradable cellulose alternatives is a key strategy for reducing the microplastic pollution generated by packaging waste.
