This technical overview explains evidence-based methods to retain and enhance carrot nutrients—primarily β-carotene (provitamin A), vitamin A, and vitamin C—throughout post-harvest handling and food processing. It synthesizes the mechanisms of nutrient loss (thermal degradation, oxidative reactions, and enzyme-mediated breakdown), and details critical control points including harvest timing, gentle mechanical washing, precise grading, and rapid pre-cooling. The paper highlights cold-chain principles, advanced low-temperature technologies (controlled-atmosphere cooling, plate freezers, individual quick freezing, and high-pressure processing), and targeted enzyme-inhibition strategies (optimized blanching, pH control, antioxidant application, and emerging enzyme inhibitors) that collectively reduce β-carotene isomerization and vitamin C oxidation. Practical application scenarios—frozen vegetable packs, ready-to-eat salads, and infant/children’s complementary foods—are addressed with specific workflows and measurable outcomes, referencing peer-reviewed studies and in-plant pilot data to demonstrate retention rates and color stability. Recommended process parameters (temperature-time windows, oxygen exposure limits, mechanical shear minimization, and packaging atmospheres) are provided to enable reproducible nutrient preservation and desirable sensory quality. Visual data presentations (nutrient retention curves, oxidation kinetics charts, and process flow schematics) and authoritative citations support technical recommendations. For tailored implementation, processors are invited to consult 丰绿农产’s technical team for custom process design.
