Frozen diced white onion refers to a deep-processed seasoning vegetable product made by quickly freezing fresh white onions (bulb parts) after dicing through low-temperature quick-freezing technology for long-term preservation. Using “quick-freezing” technology, it maximizes the retention of white onions’ pungent flavor, natural aroma, and nutritional value, with each piece maintaining a crisp texture and pure white color (some with a pale purple hue), akin to fresh white onions. This convenient frozen form breaks through seasonal limitations (fresh white onions are mainly harvested from late spring to early autumn), making it a versatile seasoning ingredient for households, catering services, and busy lifestyles. It shares the same high sulfide content (including allicin, thiosulfinate, etc.) and high-fiber profile as fresh white onions (~2.7g fiber/100g) and can be quickly cooked, perfectly adapting to modern efficient living needs.
主な利点
- 風味の保持: Quick-freezing locks in over 90% of volatile sulfides (e.g., allicin, thiosulfinate) before white onion cells fully freeze, maintaining its pungent natural flavor nearly identical to fresh white onions.
- 栄養素の保持: Low-temperature quick-freezing minimizes nutrient loss, preserving abundant vitamin C (7mg/100g), dietary fiber (2.7g/100g), and potassium (146mg/100g), matching the nutritional profile of fresh white onions.
- 利便性: No need for washing or cutting (some products are pre-processed). Thawed dice can be directly used for stir-fries, cold dishes, soups, or as a dip, releasing aroma in 30 seconds and boosting cooking efficiency.
- : -18°Cでの急速冷凍と高バリア性パッケージングを組み合わせることで、賞味期限を最大2年間に延ばすことができます（新鮮なポテトストリップの1～2日間の保存期間をはるかに超えます）。長期間の保管ニーズにも完璧に対応します。 [QWEN_MT_ITEM_11]風味の高い保持: Standardized freezing technology ensures uniform crispness in every piece (no softening or coarse fibers), maintaining a refreshing crunch even after cooking, unlike fresh onions that may degrade in texture if stored improperly.
- ヘルシーで自然: Low in calories (~40kcal/100g) and free of artificial additives (e.g., preservatives, colorants), it is rich in sulfides (with antibacterial and antioxidant properties), making it an excellent low-calorie seasoning for balanced diets.
利用シーン

品質のヒント
- : -18°C以下の安定した温度で保管し、何度も解凍・再冷凍を繰り返さないようご注意ください（これを行うと、玉ねぎのカットが水分を吸収して柔らかくなり、食感が損なわれます）。
- : 再加熱時間を適切に管理してください（電子レンジの中～高火力で30秒、沸騰したお湯に浸す場合は1分間）。長時間高温で加熱すると、ネギが柔らかくなり、香りも損なわれますのでご注意ください。
- Choose pure white onion dice (no mixed vegetables or seasonings) to ensure pure flavor and concentrated aroma.
