✦ Synopsis

in the November number of the Journal, describes in detail the methods of analysis of crude substances which contain levulose. These methods have been devised mainly for the purpose of controlling the process of levulose manufacture from the juices of the Jerusalem artichoke, but are equally valid for the analysis of other crude materials. Specifications are supplied for the hydrolysis of polysaccharides, clarification, analysis for total reducing sugar, and selective analysis for levulose. The methods are applied to honey and various fruits, in most of which levulose is found to be the predominating sugar.
