Restriction requirement

White Chocolate. There is at present no standard of identity in the United States for white chocolate. Virtually all current uses of the term white chocolate do not meet the standards for chocolate, which prescribes the presence of ground cacao nibs. This restrictive requirement has acted as a practical deterrent to companies developing and marketing white chocolate-type products in the United States. When such products have been introduced and marketed in the United States, companies have had to label them with fanciful names to avoid the standardized labeling issues. In other countries where a standard of identity for white chocolate exists and where a minimum amount of cocoa butter is required by law, consumers have available to them a variety of easily recognizable products. 

One of the significant drawbacks of multidimensional analytical methods is the specificity of the conditions of each separation mode for a particular sample type, together with restrictive requirements for the type and operational conditions of the interface between them. Therefore, extensive work in the method development stage, along with the availability of highly skilled personnel for operating such systems, are required.
