Abstract
This study investigated the feasibility of using sodium caseinate (NaCAS) to improve the properties of electrospun pullulan (PUL) nanofibres. Replacing PUL with 50% NaCAS [50:50(PUL: NaCAS)] resulted in appropriate viscosity for fibre formation (968.93 mPa.s), increased solution conductivity (1682.50 μS cm−1), decreased surface tension (59.55 mN m−1), which led to forming beadles' fibres with the smallest diameter (141.21 nm), highest water contact angles (117°), and highest thermal stability (24.03% residue weight at 600 °C). X-ray diffraction and Fourier-transform infrared spectroscopy analyses provided insights into nanofibres' structural and chemical properties and indicated successful blending of the PUL and NaCAS. Results indicated that replacing PUL with 50% NaCAS improved fibre properties. These findings contribute to the development of novel biopolymer-based nanofibres with potential applications in various industries, including food and bioencapsulation.
期刊介绍:
The International Journal of Food Science & Technology (IJFST) is published for the Institute of Food Science and Technology, the IFST. This authoritative and well-established journal publishes in a wide range of subjects, ranging from pure research in the various sciences associated with food to practical experiments designed to improve technical processes. Subjects covered range from raw material composition to consumer acceptance, from physical properties to food engineering practices, and from quality assurance and safety to storage, distribution, marketing and use. While the main aim of the Journal is to provide a forum for papers describing the results of original research, review articles are also welcomed.
