Why Does Chocolate Need Chilled Transport?
Chocolate melts at surprisingly low temperatures—between 70 ° F et 90 °F (21–32 °C), 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. Donc, cold chain shipping maintains temperatures between 12 °C et 20 °C with relative humidity below 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
| Facteur | Optimal Range | Effects of Exceeding | Ce que cela signifie pour vous |
| Température | 12 °C – 20 °C (54 °F – 68 °F) | Au-dessus de 20 °C leads to softening and fat bloom; ci-dessous 12 °C can cause sugar bloom when chocolate warms up again | You need insulated packaging and cooling agents to maintain this range |
| Relative Humidity | < 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 |
Astuces et conseils pratiques
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.
Utiliser des enregistreurs de données: Attach a temperature and humidity sensor inside the parcel to record conditions; this helps improve future shipments.
Avoid condensation: Allow chocolates to come to room temperature gradually when unpacking to prevent moisture from condensing on the surface.
Cas du monde réel: A small chocolatier found that by shipping at night and adding a humidity absorbing pack, returns due to chocolate bloom dropped by 20 %. The company saved on customer reimbursements and improved reviews.
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 à 72 heures, while active solutions integrate powered refrigeration. Selecting materials depends on transit duration, climatic extremes and sustainability goals.
Insulated Containers and Liners
Polystyrène expansé (PSE) mousse, 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.
Cooling Agents: Packs de gel vs. Matériaux à changement de phase
| Agent de refroidissement | Plage de température | Durée | Votre avantage |
| Packs de gel | Typically freeze at 0 °C and melt around 4 °C | Maintain 2–8 °C for 24–48 hours; best for short hauls | Peu coûteux et facile à utiliser; suitable for domestic shipments |
| Matériaux à changement de phase (PCMS) | Available at 10 °C, 15 °C and other set points | Maintain specific temperature for 48–120 hours | Provide precise control for premium chocolates; certains PCM sont biodégradables |
| Glace sèche | 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.
Astuces et conseils pratiques
Balance insulation thickness and weight: More insulation improves performance but increases shipping costs. For overnight shipments in mild climates, a one inch (2.5 cm) EPS wall may suffice; longer or hotter routes may need two inch walls and more gel packs.
Condition your PCMs: Freeze or refrigerate phase change materials at the recommended temperature and pre load them into the box to avoid temperature spikes.
Étiquetez clairement les colis: Mark parcels as perishable and “Keep Cool” to prompt careful handling and separate them from hot delivery trucks.
