Abstract
The development of nanoparticles loaded with natural active ingredients is one of the hot trends in the pharmaceutical industry. Herein, chitosan was selected as the base material, and sodium tripolyphosphate was chosen as the cross-linking agent. Chitosan nanoparticles loaded with β-acids from hops were prepared by the ionic cross-linking method. The results of Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) indicated that chitosan nanoparticles successfully encapsulated β-acids. The loading capacity of chitosan nanoparticles with β-acids was 2.00 %-18.26 %, and the encapsulation efficiency was 0.58 %-55.94 %. Scanning electron microscopy (SEM), transmission electron microscope (TEM), particle size, and zeta potential results displayed that the nanoparticles revealed a sphere-like distribution with a particle size range of 241-261 nm, and the potential exhibited positive potential (+14.47-+16.27 mV). The chitosan nanoparticles could slowly release β-acids from different simulated release media. Notably, the β-acids-loaded nanoparticles significantly inhibited Staphylococcus aureus ATCC25923 (S. aureus) and Escherichia coli ATCC25922 (E. coli). Besides, β-acids-loaded chitosan nanoparticles were cytotoxic to colorectal cancer cells (HT-29 and HCT-116). Therefore, applying chitosan nanoparticles can further expand the application of β-acids in biomedical fields.

Abstract
Hydrogel film composed of chitosan (CS) as raw material was prepared by free radical polymerization. Silicon was introduced into the hydrogel film in different ways (covalent/non-covalent) to improve the physical properties of the film, and β-acids were loaded to enhance the antibacterial activity of the film. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD) analysis were used to characterize the structure of films. The mechanical results indicated that when nano-silica (0.3%) was introduced into film (containing 0.2% β-acids) by non-covalently bond, the tensile strength increased to 8.59 MPa. Meanwhile silicon (0.3%) entered the film by covalent bonding, the tensile strength increased to 7.99 MPa. The films loaded with β-acids had well ability to blocks ultraviolet rays and exhibited inhibitory effect on E. coli and S. aureus. In the PBS (37 °C, pH = 7.4) simulant solution, the release mechanism of most films to release the β-acids followed non-Fick diffusion (n > 0.5). It could be concluded that the prepared hydrogel films loading with β-acids had broad application prospects in food packaging material with antibacterial property and controlled release.

Abstract
β-Acids are natural antibacterial and antioxidant ingredients, obtained from supercritical CO2 hop extract. In this study, β-acids/chitosan complex films were prepared using the casting method. Complex films were characterized using scanning electron microscopy (SEM), atomic force microscope (AFM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction analysis (XRD). Structure analysis revealed that β-acids can be successfully combined with the chitosan matrix. Mechanical tests demonstrated that the tensile strength of the films showed a significant upward trend (1.9 MPa to 9.6 MPa) with increase in β-acids content (0.1%-0.3%). Interestingly, the chitosan-based films showed excellent UV barrier capability below 400 nm. The release of β-acids from the film followed Fickian diffusion (n < 0.45). In addition, the complex films inhibited the growth of five food-borne pathogens (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Salmonella enteritidis and Listeria monocytogenes). This study highlights the promising nature of composite film as a desirable alternative for active packaging.
