Crispy dried pineapple, What is the most effective method?

When talking about dried pineapple products, we usually think of chewy dried pineapple because this product is very popular today. Crispy dried pineapple is less commonly sold due to its higher price and is only available in large supermarkets. Drying pineapple to a crispy texture while preserving its shape, aroma, natural color, and nutritional value is the real challenge. Freeze-drying is the most suitable drying equipment for this type of product; however, the machines are quite expensive.

Pineapples, also known as “Thơm” fruit, are generally high in fiber, water, and sugar. Naturally, their nutritional value is also very rich, offering many benefits to consumers. While fresh pineapple is better than dried pineapple due to its higher water content, ensuring the best quality, pineapple is a seasonal fruit and not available year-round. Therefore, dried products are always in demand and convenient to use anytime, anywhere. Because pineapples contain a lot of sugar, both hot and cold drying methods produce chewy dried pineapple. To obtain crispy, beautifully shaped dried pineapple, freeze-drying is necessary.

Generally, common fruits like pineapple, mango, longan, lychee, dragon fruit, durian, strawberry, kiwi, watermelon, etc., contain a large amount of sugar. Even specialized fruit dryers using the cold drying method only achieve a chewy texture with high-sugar fruits. To achieve a crispy, dry texture for pineapple, mango, dragon fruit, durian, avocado, etc., while preserving their natural shape and color, freeze-drying is necessary to ensure the preservation of the natural characteristics of these high-sugar fruits.

The most suitable drying machine for producing crispy dried pineapple or other crispy dried fruits, unlike fried products like crispy bananas or jackfruit, is a freeze dryer, also known as a freeze-dryer. Fried products like crispy bananas, jackfruit, and sweet potatoes are fried in oil at high temperatures in a vacuum pressure chamber. Fried fruits lose color, nutrients, and sugars, and many harmful elements appear in the long term. Freeze-dried fruits have a beautiful, natural appearance and retain their nutritional value. Freeze-dried fruits are commonly used for drying high-end products such as cordyceps mushrooms, golden camellias, and rose buds. However, the price of freeze-drying machines is quite high, so only production facilities with a suitable investment level and high-priced products can afford to invest in freeze-drying machines.
