The content of the endosperm of the coconut (Cocos nucifera L.) contains “coconut water”. This practically sterile liquid, which is prized for its delicate, albeit labile, flavour when fresh, has had a recent dramatic increase in global demand. This review examines the variances in natural composition, maturity, processing-induced compositional changes, adulterations, product recalls, classical and instrumental methods of analysis and on the available composition standards of coconut water. The review also makes recommendations on the analytical approaches to verifying the authenticty and determination of possible adulterants, but also given the variation of composition with maturity, that a weight of evidence approach should be taken in the assessment of authenticity.
