Chlorophyll Derivatives Analysis in Food and Health Applications
Summary
Chlorophyll derivatives, encompassing a wide array of porphyrin-based compounds formed through natural degradation, extraction or synthetic modification of chlorophylls, have garnered significant attention for both food science and biomedical research. In food applications, these derivatives serve as natural green colourants and functional ingredients, with stability enhanced by metallo-chlorophyll complexes or encapsulation techniques. Analytical approaches, notably high-performance liquid chromatography coupled with mass spectrometry, enable precise characterisation of these compounds and their transformation products under processing and storage conditions. From a health perspective, chlorophyll derivatives exhibit antioxidant, antimutagenic and potential anticarcinogenic activities, acting through radical scavenging, interceptor effects against dietary toxins and modulation of cell cycle pathways. Recent work has also explored bioaccessibility and metabolism within complex food matrices, dietary intake assessments across populations and the development of nano-delivery systems to improve cellular uptake and therapeutic efficacy. Together, these strands of research underscore the global importance of chlorophyll derivatives for sustainable food innovation and preventive health strategies.
