Overview

This analysis compares microwave-assisted extraction and high-pressure-assisted extraction for carotenoid recovery in tomato by-products, suggesting enhanced bioaccessibility.

Key Points

  • Microwave-assisted extraction outperformed conventional extraction, achieving 592.5 mg carotenoids/kg dry weight, highlighting its efficiency.
  • Compared to conventional extraction yields of 505.3 mg/kg dry weight, microwave-assisted extraction significantly reduced extraction time from 120 minutes to just 20 minutes.
  • High-pressure-assisted extraction showed lower carotenoid yields when used alone, but as a pre-treatment, it improved recovery to 277.0 mg/kg dry weight.
  • Bioaccessibility studies revealed low levels, with only 3.9% for high-pressure-assisted extraction and 3.4% for microwave-assisted extraction, though oil incorporation improved this.
