Enhancing the accuracy, speed, and efficiency of kafirin‐PEO electrospun bio‐nanocomposite pH indicators with red beetroot extract using image processing
Abstract Intelligent electrospun pH indicators were produced from bio‐nanocomposite kafirin‐polyethylene oxide (PEO) containing red beetroot extract. The aim was to evaluate the performance and stability of the electrospun pH indicators via image processing. Red beetroot extract was added to a mixture of kafirin and PEO at various concentrations. The mixtures were electrospun, and infrared Fourier transform spectroscopy confirmed the presence of kafirin, PEO, and red beetroot extract in the resulting pH indicator. The results showed that the pH indicators had high stability and reversibility at different temperatures, pHs, and environmental conditions. The results showed that the color of the indicators was significantly reversible after pH changes, with highly desirable reversibility observed at pH values of 1, 3, 4, 5, 7, 9, and 10. The findings proved that the red beetroot extract loaded bio‐nanocomposite pH indicator accompanied by evaluation of color characteristics through image processing technique, can serve as a time‐efficient, accurate tool for detecting and tracking pH changes caused by food spoilage.
