Research on storage of dehusked young coconut

[mike brown]

Has anyone done or does anyone know about any research done on the storage of dehusked young coconut.  Coconuts that have the entire husked removed and then stored in refrigeration, regarding how long the product quality holds, best storage temperatures and handling.

Thanks,

Michael Brown

Mike,

We have been storing dehusked young coconut in refrigerated condition for over 3 months.  Our findings are:

• Skin colour remains same
• Water taste does not change
• Quantity inside can reduce by 10-20% depending on extent of dehusking
• Shell cracks if frozen
• Safe to ship, and store in refrigerated condition. 

We supply a few hospitals in the above form and they continue to be happy.

Dear Michael

We have invented the coconut trimming machine for cutting diamond shape last year.

Now we are promoting all over the world. It can peel 6pcs per minute.

You can refer to our page

These are very useful findings Varadarajan

It confirms how secure the water is within the nut when there is no evidence of invasion by any organism during a period of three months. We find in the supermarkets in Australia that the juice in trimmed immature nuts supplied from Thailand is still OK to consume after what could easily be a similar delay as the nuts a brought by sea transport. I think that the flavour does suffer a little perhaps due to a slight chemical change.

Mike,

The observation of change in flavour could be due to the fact that the nut is either in frozen or refrigerated state.  Unless the endosperm is formed upto 70% or more, there appears to be little likelihood of chemical change.  

The biggest worry though, is the loss of content during storage.  And it is not consistent.  Some nuts lose 5% while other lose upto 20%.
