Durian is a popular cultivar due to its thick flesh, strong taste, and rich sweetness. China is the main market for durian exports with an import volume of 800 thousand tons in 2021. Compared to the import volume in 2014 of just over 300 thousand tons, the growth rate shows the high potential and value of durian exports to this market. The main countries to export durian to China are Malaysia (frozen), Thailand (fresh and frozen), Vietnam (fresh).
Particularly in Malaysia, durian is only harvested at 100% maturity, with the best taste and quality, therefore Malaysian durian is very popular and can be sold at a higher price than Thai or Vietnamese durian. Since fully ripe durian can only be stored for 3 days at a temperature of 30 degrees Celsius, durian packaging facilities in Malaysia started to use Durian freezing by liquid nitrogen technology to retain its freshness of the whole durian after harvesting and were able to extend the storage period up to 18 months.
Durian freezing by liquid nitrogen is a new freezing method in which the whole fruit is directly exposed to liquid nitrogen gas to freeze the product immediately.
Compared to the traditional compressor freezing method, which takes an average of 6-8 hours to freeze a 40-foot container reaching -18 degrees Celsius, Durian freezing by liquid nitrogen method reaches -18 degrees Celsius in just 1 hour, many times faster than usual.
The Durian freezing by liquid nitrogen method helps to lower the product temperature quickly by penetrating beyond the heat resistance of the product and creating ice around it, helping to lock in natural flavors, nutrients, and moisture. Durian freezing by liquid nitrogen prevents water loss up to ten times more effectively than conventional freezing methods and reduces the harmful effects of frozen water crystals on the microstructure of fruit flesh tissues during freezing.
