quick-freezing
Rapid temperature plunge
Quick-freezing is rapidly freezing food at very low temperatures to preserve freshness and texture.
Unlike slow freezing, which forms large ice crystals that damage cell walls, quick-freezing creates tiny crystals that leave food nearly intact when thawed.
The process revolutionized food preservation and distribution: quick-frozen vegetables, quick-frozen fish fillets.
