Although chestnuts are delicious, their short shelf life and susceptibility to browning during processing pose challenges for the industry. Nowadays, with quick-freezing technology, chestnut kernels can be rapidly frozen to below -30℃ within hours of harvesting, maximizing their moisture, sweetness, and texture. Meanwhile, low-temperature vacuum frying or non-frying baking processes can produce crispy and fragrant chestnut kernels that are ready to eat right out of the bag, without the need for preservatives. The application of these technologies allows global consumers to enjoy chestnut products that closely resemble freshly harvested flavors all year round, and has facilitated the transformation of chestnuts from seasonal snacks to everyday healthy foods.
