Mid-Autumn Festival 2025: The Worry of Mold Behind Delicious Mooncakes

As the Mid-Autumn Festival approaches, the air is filled with the festive aroma of baked and snow skin mooncakes. However, behind this joyous celebration lies a significant concern for both home bakers and large-scale manufacturers: the humid weather of the September rainy season. This is the number one enemy that can ruin an entire batch of heartfelt-made mooncakes in just a few days.

Mooncakes, with their high sugar, oil, and moisture content, are an ideal breeding ground for mold and bacteria when exposed to high ambient humidity. This issue not only leads to waste but also directly affects consumer health and brand reputation.

Common Risks When Humidity is Uncontrolled

🍄

Mold & Mildew

Green and white mold spots appear on the surface, completely ruining the cake.

💧

Oil Sweating & Seepage

The crust becomes damp and soggy, and the filling sweats oil, causing the cake to spoil quickly and lose its delicious taste.

📅

Reduced Shelf Life

Cakes spoil before their stated expiration date, leading to economic losses and loss of customer trust.

Part 1: Tips for Preserving Mooncakes at Home

For homemade batches, you can apply the following tips to extend their freshness:

Cool Completely: Never package mooncakes while they are still warm, as the steam will condense inside and cause mold.
Use Desiccant Packets: Always place a food-grade desiccant packet inside each mooncake box.
Refrigerate Properly: Place the mooncakes in an airtight container before putting them in the refrigerator to prevent them from drying out.
A Proactive Solution: If you bake frequently or your home is prone to high humidity, a Olmas home dehumidifier will help control the humidity in your kitchen, ensuring an ideal environment for baking and storage.

Part 2: Professional Solutions for Large-Scale Factories

On an industrial scale, manual methods are insufficient. Humidity control must be implemented proactively and comprehensively throughout the entire process to ensure the quality of thousands of products. DeAir industrial dehumidifiers play a key role in three critical stages:

The Standard Mooncake Production Process - Mold Prevention with DeAir

1. Cooling Area

After baking, mooncakes release a large amount of steam. A DeAir dehumidifier keeps the air dry, allowing the cakes to cool faster and the surface to dry properly without becoming sticky.

2. Packaging Area

Maintaining low humidity in the packaging room ensures that the air trapped inside the bags/boxes is dry, preventing the risk of mold growth from within.

3. Finished Goods Warehouse

Protecting thousands of cakes awaiting shipment in a 24/7 humidity-controlled environment ensures they maintain their quality until they reach the consumer.

Choosing the Right DeAir Equipment:

For small-scale and handmade bakeries: The Olmas industrial dehumidifier series (OS-55, OS-150), with their portable and flexible design, is an ideal choice.
