Introduction to Frozen Diced Green Onion
Frozen diced green onion refers to a deep-processed seasoning vegetable product made by quickly freezing fresh green onions (both white and green parts) after dicing through low-temperature quick-freezing technology for long-term preservation. Using “quick-freezing” technology, it maximizes the retention of green onions’ natural aroma, pungent flavor, and nutritional value, with each piece maintaining a crisp texture and bright green color (the white part appears semi-transparent jade). This convenient frozen form breaks through seasonal limitations (fresh green 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 volatile oil (containing allicin, diallyl trisulfide, etc.) and high-fiber profile as fresh green onions (~2.5g fiber/100g) and can be quickly cooked, perfectly adapting to modern efficient living needs.
Key Advantages
- Aroma preservation: Quick-freezing locks in over 90% of volatile essential oils (e.g., allicin, diallyl trisulfide) before green onion cells fully freeze, maintaining aroma intensity nearly identical to fresh green onions.
- Pure flavor: Free of artificial additives (e.g., preservatives, colorants), it retains green onions’ natural pungency through blanching and quick-freezing (some products are lightly salted for flavor), with no off-odors or rancidity.
- Vibrant color: Standardized blanching (with ascorbic acid for color protection) effectively inhibits chlorophyll degradation, keeping the green part bright and the white part semi-transparent jade (matching the color of freshly picked green onions within 2 hours).
- Convenient flavor enhancement: No need for washing or cutting (some products are pre-processed). Thawed dice can be directly used for stir-frying, cold dishes, soups, or as a dip, releasing aroma in 30 seconds and boosting cooking efficiency.
- Healthy and natural: Low in calories (~34kcal/100g) and high in fiber (2.5g/100g), rich in sulfides (with antibacterial and antioxidant properties) and vitamin C (14mg/100g), making it an excellent low-calorie seasoning for balanced diets.
Application Scenarios
- Daily home cooking: Thawed dice are directly added to stir-fries , cold dishes to instantly enhance aroma.
- Restaurant seasoning: Used in dips, noodle dishes, or as a garnish to elevate dining experiences.
- Healthy light meals: Aromatic topping for salad bowls (with lettuce, chicken breast, avocado) or blended into smoothies (with bananas and spinach) to add fiber and flavor.
- Quick convenience: Soaked in boiling water (1 minute) or microwaved (30 seconds) to quickly enhance instant noodles, rice balls, or other fast foods.
Quality Tips
- Store at a stable temperature below -18°C; avoid repeated thawing and refreezing (causes scallion dice to absorb water, soften, and lose aroma).
- Control reheating time (microwave on medium-high for 30 seconds, boiling water soaking for 1 minute). Avoid prolonged high heat (causes softening and aroma loss).
- Choose pure scallion dice (no mixed vegetables or seasonings) to ensure pure flavor and concentrated aroma.
