Scales method, reducing sugars

Sugars are estimated with reducing DNS reagent, based on the colorimetric method developed in an earlier module. Die samples are determined by colour developed, which is detected by a spectrophotometer at a wavelength of 540 nm. In large-scale operations, mycelia are separated by a rotary drum filter. 

Sugars with a potential aldehyde function can be reduced electrochemically at electrodes of mercury or amalgamated lead [23]. The rate of this process is controlled by the rate for the conversion of the cyclic to the open-chain form of the sugar. A technical-scale plant [24] for the conversion of glucose to either sorbitol or mannitol was operated in the past, but this method has largely been ousted by other processes. Glucose is converted to... 

However, in the evaporation of thermally sensitive liquids, where scale is known to result from degradation products produced by slow reactions—e.g., evaporation of fruit juices, sugar solutions, etc.—spray evaporation may be one method of reducing or avoiding scale.
