“…Compared with BCC membrane, the antibacterial effect of the BCF composite membranes increased sharply after CF incorporation. It is mainly due to the presence of FA with high bactericidal activity, which was consistent with the previous research 53,54 . The experimental results also showed that when the chitosan:FA ratio was 1:0.3, the inhibition zone of both microorganisms was the largest.…”

Bacterial cellulose (BC) is a biomaterial with many excellent properties, but its application as a food packaging and biomedical material is limited due to its lack of antibacterial properties. In this study, ferulic acid (FA) grafted self-assembled bacterial cellulose-chitosan (BCF) membranes were prepared by soaking BC films in chitosan-ferulic acid (CF) solution to synthesize antibacterial biomaterials. 1 H NMR confirmed that FA grafted onto chitosan successfully. The results of field emission scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and tensile analysis showed that CF were successfully incorporated into BC matrix and the BCF membranes had good physical properties. The antibacterial experiments demonstrated that BCF membranes had an excellent antibacterial effect against Staphylococcus aureus and Escherichia coli. Therefore, combining all these properties, BCF composite membranes would have potential application in food packaging or wound-healing materials.

“…In food processing, polyphenols are readily oxidized to electrophilic quinones, which can subsequently crosslink with proteins [ 10 ]. Previous studies have shown that ferulic and tannic acids, two widely distributed natural phenols, have antimicrobial and antioxidant activity [ 11 , 12 ]. Both also have the potential to improve the mechanical properties and decrease the water vapor permeability of collagen- or gelatin-based films [ 13 , 14 ].…”

Protein-based biodegradable packaging films are of environmental significance. The effect of oxidized ferulic acid (OFA)/tannic acid (OTA) on the crosslinking and film-forming properties of whey protein isolate (WPI) was investigated. Both of the oxidized acids induced protein oxidation and promoted WPI crosslinking through the actions of quinone carbonyl and protein sulfhydryl, and amino groups. OTA enhanced the tensile strength (from 4.5 MPa to max 6.7 MPa) and stiffness (from 215 MPa to max 376 MPa) of the WPI film, whereas OFA significantly increased the elongation at break. The water absorption capability and heat resistance of the films were greatly improved by the addition of OTA. Due to the original color of OTA, the incorporation of OTA significantly reduced light transmittance of the WPI film (λ 200–600 nm) as well as the transparency, whereas no significant changes were induced by the OFA treatment. Higher concentrations of OTA reduced the in vitro digestibility of the WPI film, while the addition of OFA had no significant effect. Overall, these two oxidized polyphenols promoted the crosslinking of WPI and modified the film properties, with OTA showing an overall stronger efficacy than OFA due to more functional groups available.

“…Soleimani et al (2017) stated that the chitosan application at 6.5 mg/mL had a good potency as prebiotics compounds due to the ability of Lactobacillus to grow. Additionally, Asim et al (2020) pursuing that the antibacterial activity of chitosan influence by some factors such as the type of chitosan, the deacetialation degree, pH and other physicochemically characters. Chitosan was able to immobilise the bacteria by providing the nutritional requirements and as a matrix.…”

Lately, chitosan as a result of chitin deacetilation has known as potencial compound as food industry, pharmacy and environmental agents. The weakness of chitosan is the low water solubility and high viscosity. The size reduction by cutting the β-1, 4 glicosidic bond to improve the bioactivity is the alternative solution. This research aims to find out the addition of chitosan and COS for the Streptococcus thermophillus FNCC – 0041 and Lactobacillus bulgaricus FNCC – 0040 probiotics bacteria culture. S. thermophillus and L. bulgaricus were cultured in the MRS Broth media with addition of Commercial Chitosan (CC), Commercial Oligochitosan (COC), Self-production Chitosan (PC) and Self-production Oligochitosan (POC) in different doses (0.05; 0.1; and 0.2 mg.ml-1). Percentage DD on those treatments was similar. The spectra vibration of The FT-IR analysis of PC and POC were fit to the CC and COC. In chitosan treatments, the best growth of S. thermophilus was reached at 0.2 mg/mL PC, while in chitooligochitosan was from 0.20 mg/mL COC treatments, respectively. The addition of different type of chitosan have a significant effect (p<0.05) to the growth of S. thermophillus, but have not resulted the significant effect to the L. bulgaricus (p>0.05) growth. So, therefore the addition of chitosan and COS as prebiotics for the probiotics were in dose dependant manner. Compare to chitosan commercial, our chitosan production have a good potency to be developed.
