Dried green peppercorns retain their original shape and color

We are usually familiar with dried black peppercorns, but we are not yet familiar with dried peppercorns that retain their natural green color. These are called freeze-dried green peppercorns because only freeze-drying ensures that the green peppercorns retain their original color and round shape. In this article, Mactech will analyze freeze-dried green peppercorns to help readers understand them better.

Drying green and red peppercorns while preserving their plumpness and natural color is not easy; conventional drying methods such as hot and cold drying struggle to achieve this. Similarly, products that are difficult to dry, such as yellow camellia flowers, rose buds, green tea leaves, rose blossoms, jasmine buds, etc., require freeze-drying to achieve the desired high quality.

The image above shows green peppercorns dried using a Mactech freeze-drying machine. The dried peppercorns remain plump and round, retaining their original green color, although they are prone to falling off the cluster. A gentle squeeze will easily break the outer shell, although the hard core still needs to be ground. Freeze-dried peppercorns can be stored for months or even years while maintaining good quality. Similarly, other soft products like tomatoes, dragon fruit, ripe mangoes, durian, strawberries, kiwi, starch, and probiotics also require freeze-drying to ensure preservation of their natural shape and color.

 

Watching the video, we can see the characteristics of freeze-dried green peppercorns. Only by applying the freeze-drying principle can such quality be achieved. The drying temperature is usually -30°C and the drying chamber pressure reaches a vacuum level. The water in the product is completely frozen, allowing the sublimation process to transform it into vapor. The dried product always has a porous, crispy powder texture. Even durian segments dry crisply without deformation or discoloration after drying.

However, freeze dryers are currently quite expensive; a machine capable of handling around 5kg of material costs approximately 150 million VND. Therefore, only businesses with sufficient resources and a market for high-value products should invest in this type of dryer. For more detailed advice, please contact Mactech directly at 0984898720.
