Never make runny marmalade again with the marmalade

Experiment to compare cooking temperature to marmalade set I cooked up a batch of three fruit marmalade using the whole fruit method (no pectin) I measured the temperature as the marmalade bubbled away with an instant read thermometer the Thermapen which is very fast at registering temperatures and temperature changes but a probe thermometer with a longer cable like the

PRODUCTION OF 5

However the separation of HMF from these high-boiling point solvents is difficult leading to thermal degradation of the HMF product Some interesting results have been presented on the dehydration of carbohydrates in ionic liquids which have unique properties such as negligible vapor pressure and comparative thermal stability ( Van Putten et al 2013 Zakrzewska et al 2011 )

Kinetics of the Decomposition of Fructose Catalyzed by

This paper deals with the dehydration of fructose (F) to 5-hydroxymethylfurfural (HMF) and the rehydration of HMF to levulinic acid (LA) along with formic acid (FA) in subcritical water (sub-CW) in the presence of HCl as catalyst The experimental conditions were 483−543 K 4−15 MPa and residence times of 0 5−300 s The pressure (in the range of 4−15 MPa) did not affect the
