Frozen diced red onion refers to a deep-processed vegetable product made by quickly freezing fresh red onions (bulb parts) after dicing through low-temperature quick-freezing technology for long-term preservation. Using “quick-freezing” technology, it maximizes the retention of red onions’ nutritional value, natural pungent flavor, and vibrant color, with each piece maintaining a crisp texture and deep purplish-red hue (some varieties appear violet-red), akin to fresh red onions. This convenient frozen form breaks through seasonal limitations (fresh red onions are mainly harvested from late spring to early autumn), making it a versatile flavor-enhancer for households, catering services, and busy lifestyles. It shares the same high sulfide content (including allicin, quercetin, etc.) and high-fiber profile as fresh red onions (~2.7g fiber/100g) and can be quickly cooked, perfectly adapting to modern efficient living needs.

  4. Balanced nutrition: Low in calories (~40kcal/100g) and high in fiber (2.7g/100g), rich in quercetin (antioxidant) and vitamin C (7mg/100g), making it an excellent low-calorie seasoning for balanced diets.
  5. Year-round availability: Breaks through seasonal shortages of fresh red onions (e.g., winter scarcity) through quick-freezing, ensuring stable supply for households and catering services.

Quality Tips​

  1. Store at a stable temperature below -18°C; avoid repeated thawing and refreezing (causes onion dice to absorb water, soften, and lose texture).
  2. Control reheating time (microwave on medium-high for 30 seconds, boiling water soaking for 1 minute). Avoid prolonged high heat (causes softening and flavor loss).
  3. Choose pure red onion dice (no mixed vegetables or seasonings) to ensure pure flavor and concentrated aroma.
