Article Synopsis
  • A study in Romania analyzed the antioxidant activity of organic and non-organic apple varieties using a specific method called DPPH kinetics-PCA.
  • Organic apples showed significantly higher antioxidant activity compared to non-organic ones across different parts of the apple (core and shell).
  • The research highlights that the DPPH reaction rate during the initial half-minute was key in differentiating between the apple types, marking the first use of this method for such evaluations in fruits.

Article Synopsis
  • - The study investigates the antioxidant activity of different parts of unripe and ripe papaya (including peel, pulp, seed, and seed-pulp) by measuring their reaction with a compound called DPPH·.
  • - Ripe papaya pulp showed the highest radical scavenging capacity (86.4%) compared to unripe pulp (41.3%), indicating that ripeness significantly affects antioxidant levels.
  • - The DPPH· reaction rates were notably higher for ripe papaya extracts (2.70 to 4.00 μM/s) than for unripe ones (1.00 to 1.80 μM/s), demonstrating the effectiveness of using DPPH· kinetics to assess antioxidant properties
