Encapsulation and antibacterial studies of goji berry and garlic extract in the biodegradable chitosan

As known, the chitosan is a biodegradable biopolymer with antibacterial properties, therefore it is used in the fields of pharmacy, medical, wastewater treatment, biotechnology, cosmetics, textiles, and agriculture. Apart from these, the chitosan has an important place in the food industry with its widespread use. In this research article, the chitosan were encapsulated with the taurine and garlic extracts by the spray dryer. The CSA and CSB compounds synthesized as final products were analyzed by Fourier transformed infrared spectroscopy (FTIR) and High Performance Liquid Chromatography (HPLC). The effect of the encapsulation process on the molecular weight of the polymer structure was investigated using the cryoscopy method. The compound CSA represents 1/2 encapsulation of chitosan with taurine and increased garlic extracts, respectively, while CSB represents 1/1 encapsulation of chitosan with increased taurine and fixed garlic extracts. The % antioxidant activity of the final products was determined by DDPH method. The inhibition zone and surface activity proporties of the CSA and CSB were carried out against Listeria monocytogenes, Staphylococcus aureus, E. coli, and Salmonella bacteria. The results obtained as a result of the analyzes were evaluated, and optimum values were determined for use in food packaging.
