Key Points

To investigate how different harvest timings affect the functional components and antioxidant capacity of various paprika varieties.
Conducted greenhouse cultivation over two years (2014 and 2015).
Sampled five different paprika varieties at varying harvest times.
Analyzed levels of gamma-aminobutyric acid and luteolin along with antioxidant capacity.
Luteolin levels were generally higher from October to December.
Gamma-aminobutyric acid and antioxidant capacity varied by variety and harvest timing.

Implication

Demonstrates the influence of harvest timing on antioxidant capacity in greenhouse-grown paprika, suggesting optimal timing for better quality.
