لماذا تحتاج الشوكولاتة إلى النقل المبرد؟?
Chocolate melts at surprisingly low temperatures—between 70 درجة فهرنهايت و 90 ° f (21-32 درجة مئوية), depending on cocoa butter content—and absorbs moisture easily, leading to sugar and fat bloom. When exposed to heat or humidity, chocolate loses its glossy temper and develops white streaks and gritty texture. لذلك, cold chain shipping maintains temperatures between 12 درجة مئوية و 20 درجة مئوية مع رطوبة نسبية أدناه 50 % to preserve flavor and appearance. These conditions prevent condensation and bloom, which can make confections less appealing and shorten shelf life.
Maintaining the right environment is not just about luxury. Chocolates are high fat emulsion products: they melt easily and re crystallize unevenly when temperatures fluctuate. In humid air, sugar dissolves on the surface and recrystallizes, creating sugar bloom. Fat bloom occurs when cocoa butter separates from cocoa solids under warmth. Keeping chocolate below its melting point and away from moisture protects both taste and brand reputation. It also reduces waste, boosting profitability.
How Temperature and Humidity Affect Chocolate
| عامل | النطاق الأمثل | Effects of Exceeding | ماذا يعني لك |
| درجة حرارة | 12 درجة مئوية – 20 درجة مئوية (54 درجة فهرنهايت – 68 ° f) | فوق 20 °C leads to softening and fat bloom; أقل 12 °C can cause sugar bloom when chocolate warms up again | You need insulated packaging and cooling agents to maintain this range |
| الرطوبة النسبية | < 50 % | High humidity dissolves sugar on the surface, creating a grainy bloom; low humidity maintains gloss | Use moisture barrier films and desiccants to control humidity |
| Handling Time | < 48 hours for passive cooling; longer with active cooling | Longer transit increases risk of melting or moisture ingress | Select packaging that matches transit duration and climate |
نصائح ونصيحة عملية
Pack early and chill your packages: Place finished chocolates in a cool, dry environment before packing. Pre chill the insulated container and coolant for better performance.
استخدام مسجلات البيانات: Attach a temperature and humidity sensor inside the parcel to record conditions; this helps improve future shipments.

How to Choose Protective Packaging Materials?
The key to chilled chocolates packaging lies in the combination of insulation and coolant. Passive cooling solutions—insulated boxes plus gel packs or phase change materials—maintain temperature for 24 ل 72 ساعات, while active solutions integrate powered refrigeration. Selecting materials depends on transit duration, climatic extremes and sustainability goals.
Insulated Containers and Liners
البوليسترين الموسع (EPS) رغوة, cotton insulation, starch based foam and recycled paper liners are common insulators for chocolate shipping. EPS offers strong thermal resistance and moisture protection but is hard to recycle. Cotton and starch based foams are biodegradable and provide cushioning, though they may be less rigid. Recycled paper liners paired with reflective foil create air pockets that reduce heat transfer and are curbside recyclable.
Performa Nova, a fiber based board, is a newer option. It resists moisture, maintains structural integrity under compression and reduces plastic content by up to 75 %. It is well suited for chilled and frozen confectionery because it withstands high humidity and offers brand friendly printing.
وكلاء التبريد: حزم هلام مقابل. مواد تغيير المرحلة
| عامل التبريد | نطاق درجة الحرارة | مدة | مصلحتك |
| حزم هلام | Typically freeze at 0 °C and melt around 4 درجة مئوية | Maintain 2–8 °C for 24–48 hours; best for short hauls | Inexpensive and easy to use; suitable for domestic shipments |
| مواد تغيير المرحلة (PCMS) | Available at 10 درجة مئوية, 15 °C and other set points | Maintain specific temperature for 48–120 hours | Provide precise control for premium chocolates; بعض PCMs قابلة للتحلل |
| الجليد الجاف | Sublimates at –78.5 °C | Keeps items frozen for 24–72 hours; not suitable for chocolate as it may freeze and crack | Use only if you must ship other frozen products with chocolate |
Protective Primary Packaging
Inside the insulated box, use food grade, moisture barrier wrappers such as foil laminated paper or resealable pouches. A snug secondary box or rigid tray prevents movement and breakage. Pillow and gusset bags are popular for candy and allow hanging displays; they reduce material use by up to 15 %. Include cushioning like bubble wrap or paper to minimize vibrations.
