Crispy dried durian, Which drying method is most effective?

Although crispy dried durian is a premium dried fruit product, not everyone enjoys it. Aside from the durian’s unique flavor, the characteristic of this dried product is its porous, powdery texture, giving it a texture similar to eating fruit powder. What drying method is most effective for producing this type of crispy dried fruit? Let’s explore the information below to understand this better.

Compared to other fruits, durian is arguably the most difficult to dry using most current drying methods. Both hot and cold drying methods struggle to dry durian segments into a chewy, mushy consistency, similar to fatty pork. Drying is not a simple task. Generally, fruits with high sugar and water content, such as bananas, jackfruit, mangoes, pineapples, and dragon fruit, are already difficult to dry, but they are still easier than durian, not to mention drying durian to a crispy texture.

Currently, most common dried fruit products are chewy dried fruits like chewy dried pineapple, chewy dried dragon fruit, chewy dried jackfruit, chewy dried banana, etc. Crispy dried fruits like crispy sliced ​​bananas, crispy jackfruit, crispy sweet potatoes, crispy potatoes, etc., are usually deep-fried. Truly crispy dried fruits require freeze-drying to ensure they retain their natural shape and color; however, this method is quite expensive and more difficult to sell.

The ideal drying machine for drying durian to a crispy texture is the freeze dryer. This is the most advanced and specialized drying equipment currently available, ensuring that all dried fruits are crispy, retain their shape and natural color, and preserve their nutrients. Crispy dried fruits differ significantly from crispy fried fruits. However, consumers often don’t understand this and trust products sold haphazardly on the market, such as crispy bananas, crispy jackfruit, crispy potatoes, etc., many of which are actually deep-fried using high-temperature oil in vacuum fryers. Although fried fruits are crispy, their nutrients are altered, their sweetness and aroma are reduced, and consuming them in large quantities is not good for health.

Crispy dried durian and other crispy dried fruits made using the freeze-drying method must be frozen at -30°C, then the drying chamber is vacuumed to ensure efficient sublimation of the ice. Of course, the drying process involves several stages with varying temperature parameters to ensure the product dries quickly and has the best quality. The maximum temperature during drying does not exceed 30°C, so the product retains its best nutritional value and is safest for consumers.
