Many individuals rely on commercially produced pH indicators, which can be costly and are not typically food-safe. In contrast, homemade pH indicators offer a cost-effective and food-grade alternative. This accessibility may be particularly beneficial for individuals with health conditions such as acid reflux, as it enables them to monitor the acidity of foods and make more informed dietary decisions.

Thank you for continuing to do sustainable research! I’m a strong supporter of bio-based products that can replace toxic and harsh chemicals used in many man-made materials today. Your work highlights the great potential of biomolecules to create safer and more sustainable solutions. Keep pursuing this path; you will both become excellent biochemists!
This is a great project.
