The thermalgravimetric and differential scanning calorimetry analysis were used to evaluated the state of stearic acid in the soybean protein-isolate/carboxymethyl cellulose composite films. The stearic acid lose its weight rapidly in 210~280 oC, while no significant weight loss presented among 210~280 oC in the profiles of the control and the composite films dried at 90 oC. Hence, the stearic acid was well interacted with the other ingredients. Moreover, the stearic acid was distributed as the free state and bound state in the composite films. The free stearic acid ratio of the composite films dried at 90 oC was the lowest among the tested films. The temperature of 90 oC effectively enhanced the interaction of the SA with the other ingredients.

The effects of beeswax, palmitic acid and stearic acid on properties of soybean protein-isolate/carboxymethyl cellulose composite films were compared. The palmitic acid leaded to a higher tensile strength, water vapor barrier and oxygen barrier of composite films than the beeswax and stearic acid. However, the palmitic acid lowered the elongation at break and leaded to a slight yellow. Hence, the palmitic acid was a better option to improve the tensile strength and water vapor barrier of soybean protein-isolate/carboxymethyl cellulose composite films.

Novel bioactive films based on pectin and cellulose (PC) with different loadings of tea polyphenols and cinnamaldehyde were successfully prepared. A thermal stability was tested, and the results showed that the thermal stability decreased slightly after loading with cinnamaldehyde and tea polyphenols, compared to PC films. The antimicrobial and antioxidant capacities were also investigated. Results showed that PC composite films had good DPPH radical and hydroxyl radical scavenging activities and excellent antibacterial activities against Escherichia coli, Candida albicans and Staphylococcus aureus. Based on the results, the great antioxidant and antibacterial activities of the tea polyphenol and cinnamaldehyde loaded PC films make them suitable for food packaging and preservation.
