ISI 34-1e Determination of Baumé of Starch Slurry by Aerometer


1. Scope The method is applicable to starch slurry

 

 LT 15 Jan 1998
2. Principle Slurry density is interpreted as concentration of slurry

 
3. Apparatus 3.1 Aerometer 0 - 10 Béo
3.2 Aerometer 0 - 25 Béo
3.3 Cylinder, slim 100 ml

 
4. Procedure Keep aerometers floating in cylinder or bucket with water.
Fill cylinder (3.3) to the brim with starch slurry. Immerse appropriate aerometer (3.1 or 3.2) and let float.
Read immediately the degree of Baumé on aerometer stem

 
5. Calculation Report reading as starch concentration in degree Baumé (Béo) with one decimal

 
6. Note Entrapped air has to be released and starch re-slurred before aerometer is read.
The centrifuge is superior to the aerometer as a process tool being indifferent to entrapped air and rapid settling starch. ISI 33
With Beaumé as entry table values of density etc may be found ISI Starch Slurry Viscosity Table

ISI 01-1e Determination of Dry Matter in Starch by Oven Drying at 130 oC

Return 1. Scope The method is applicable to starch in native or modified form. LT 15 Dec. 1964 Rev.: LT 21 Nov. 1997 2. Principle The sample is dried to constant weight. 3. Apparatus 3.2 Dish of aluminium or glass with tight-fitting lid 3.3 Electrically heated constant-temperature oven. 3.4 Desiccator with dry drying agent 4. Procedure An empty dish (3.2) is dried 1/2 hour in oven (3.3) at 130  o C. Cool dish in desiccator (3.4) to room temperature and weigh on balance (3.1) to the nearest 1 mg. Weight = w 0   Let cool 40 min Distribute 5 g of sample in a uniform layer in dish. Close lid and weigh to the nearest 1 mg. Weight = w 1 Place the open dish with sample in oven preheated to 130  o C. Dry 90 minutes after oven has once again reached 130  o C. Close lid and cool in desiccator for 30 to 45 minutes. Weigh immediately after rem
