  1. Machine learning for storage duration based on volatile organic compounds emitted from 'Jukhyang' and 'Merry Queen' strawberries during post-harvest storage

    • Postharvest Biology and Technology
    • Strawberry (Fragaria × ananassa Duch.) is a widely favored horticultural crop renowned for its unique taste and flavor. To develop an accurate predictive model for strawberry freshness, colorimetric data, total soluble solids, titratable acidity, and volatile organic compounds (VOCs) were investigated in fully ripe 'Jukhyang' and 'Merry Queen' strawberries. Data measurements were conducted after 0, 4, 8, and 12 days of cold storage (10 °C, 79% RH).
