Fresh coconut water can be stored for a period of 4-6 weeks and still retain the natural quality - this is the solution of MA. Tran Yen Thao, Research Institute of Oil and Oil crops (District 1, Ho Chi Minh City) has conducted successful research, opening up the prospect of exporting fresh coconut.

MSc. Tran Yen Thao and survey findings sodium metabisulfite substances - chemicals permitted for use in food processing - can be used to process external surface of coconut shell (coconut peel the outer shell). Research survey showed a dose and time using appropriate treatment, sodium metabisulfite exist only outside coconut, both the whitening effect is capable of destroying microorganisms outside the coconut shell . Do not leach chemicals inside, rice and coconut water remain natural. After surface treatment chemical sodium metabisulfite, coconuts will continue to be surrounded by a membrane (specialized preserved fruit) and stored at approximately 5 ° C. With this processing coconut direction will keep the fruits fresh (outside color is white coconut, without browning) in the range of 4-6 weeks.

Currently in our country are a number of solutions to preserve fresh coconut as "rapidly deep-frozen method" (at negative 35 to 40 degrees C, and stored at negative 18 degrees C), this solution satisfies for preservation of fresh coconut to serve export restrictions is however relatively high price and not quality fresh coconuts that had been frozen products. An alternative is to "burp preservatives inside coconuts", this restriction of the solution is to change the quality of the coconut (the presence of chemicals in coconut milk). With the direction of MA processing. Tran Yen Thao, the limitations of the two solutions has to be overcome.

MSc. Tran Yen Thao said she has applied this test solutions for a number of the shipment to Korea (transported by ship). Initial results are very encouraging results: after 4 weeks, while South Korea, coconuts still in fresh condition. This success could open the way for export of fresh coconut water market to South Korea, Japan and Europe ...
