Optimal Temperatures: What Keeps Frozen Foods & Ice Cream Safe?
الأطعمة المجمدة, بما في ذلك اللحوم, المأكولات البحرية والحلويات, must remain within narrow temperature ranges to maintain quality and prevent spoilage. ال Food and Agriculture Organization recommends storing frozen goods between –15 °C and –25 °C, بينما International Dairy Foods Association (IDFA) states that ice cream should be kept at 0 ° f (-18 درجة مئوية) أو أكثر برودة to remain consumable. Long term storage for commercial ice cream often goes even lower: an industry standard of –28.9 °C prevents heat shock damage. Home freezers, على الجانب الآخر, should maintain 0 درجة فهرنهايت أو أقل to preserve vitamin content, color and texture, و National Center for Home Food Preservation advises freezing and storing food at 0 °F or lower.
Why zero degrees Fahrenheit matters for ice cream quality
Ice cream’s creamy texture relies on a delicate balance of fat and ice crystals. When stored above –5 °F to –10 °F (–20 °C to –23 °C), ice crystals start to melt and refreeze, creating a grainy texture and degrading flavor. ال IDFA confirms that ice cream should be stored at zero degrees Fahrenheit or colder. For long term commercial storage, specialists recommend keeping ice cream between –10 °F and –20 °F. Serving, لكن, occurs at slightly warmer temperatures—5 درجة فهرنهايت إلى 10 ° f—to allow easy scooping without compromising texture.
