Description
Technical field
A kind of application method of STEVIA REBAUDIANA liquid glucose extraction element, is related to experimental apparatus technical field, is one more specifically
It realizes that automatic liquid-feeding carries out the application method of chromatographic column wash mill in kind STEVIA REBAUDIANA liquid glucose extraction process, chromatography can be effectively controlled
Liquid level in column saves operator's experimental period, improves operating efficiency.
Background technique
The stevioside sugariness contained in STEVIA REBAUDIANA blade is 250-300 times of sucrose, but institute's heat content is only sucrose
1/300, it is the natural sweetener for being currently known most sweet tea.The sweet ingredient contained in STEVIA REBAUDIANA blade mainly has ten kinds: STEVIA REBAUDIANA
Glucosides (STV), sweetleaf alantol disaccharide glycosides (STB), rebaudioside A, B, C, D, F, M (RA, RB, RC, RD, RF, RM), Dole can glycosides
A (DA) and Rubusoside (RUB).The mouthfeel and sugariness of different steviol glycosides are all different, the sugariness of RA be higher than stevioside STV and
Taste is better than STV, therefore using the content of RA and RA proportion as the main of STEVIA REBAUDIANA kind and steviol glycoside quality evaluation
Index.
Stevioside measurement generally uses high performance liquid chromatography, and accuracy is high, but to stevia extracting solution purity
More demanding, if containing more impurity in liquid glucose, measurement operation base line is more difficult to be run steadily, also more difficult in chromatogram to accurately identify
Each glucosides peak figure, influences the accuracy of each Glycosides Contents of measure and calculation, so to remove institute as far as possible in the extraction of liquid glucose
It is impure.The liquid glucose of higher degree generally uses resin chromatography column method to purify liquid glucose in order to obtain in experiment, i.e., by stevioside leaf
Leaching liquor, which pours into, absorbs and filter each glucosides in leaching liquor in resin chromatography column, remove impurity using acid, alkali and distillation water washing,
Finally with ethyl alcohol will be adsorbed on glucosides in resin dissociate come.Drop speed is 1 drop/sec when acid, neutralizing treatment, and ethyl alcohol dissociates glucosides drop speed
It is 1 drop/3 seconds, distills the unlimited flow velocity of water washing, can flow down naturally；A sample is purified in this way and needs 8-9 hours, and is operated
Person cannot leave, the liquid feeding into chromatographic column frequently.
By the present invention in that " h " the shape siphon pipe with liquid reserve tank and with air bag, density switch preferably realize washing when
