Baking Powder
A mixture of powdered compounds added to dough or cake mixture to make it rise in cooking. It is used as a substitute for yeast in bread-making. Baking powders consist of a source of carbon dioxide, such as sodium hydrogencarbonate or ammonium hydrogencarbonate, and an acidic substance such as calcium hydrogenphosphate, potassium hydrogentartrate (cream of tartar), or sodium hydrogenphosphate. ...
متن کاملBaking Powder Actuated Centrifugo-Pneumatic Valving for Automation of Multi-Step Bioassays
We report a new flow control method for centrifugal microfluidic systems; CO2 is released from on-board stored baking powder upon contact with an ancillary liquid. The elevated pressure generated drives the sample into a dead-end pneumatic chamber sealed by a dissolvable film (DF). This liquid incursion wets and dissolves the DF, thus opening the valve. The activation pressure of the DF valve c...
متن کاملBritain Kinetics of Thiamin Cleavage by Sulphite
Results are presented on the rate of thiamin cleavage by sulphite in aqueous solutions as affected by temperature (20-700), pH (2.5-7.0), and variation of the concentration of either thiamin (1-20,UM) or sulphite (10-5000,UM as sulphur dioxide). Plots ofthe logarithmn ofpercentage ofresidual thiamin against time were found to be linear and cleavage thus was first-order with respect to thiamin. ...
متن کاملbaking industry
Objectives-To assess the exposure to enzymes and prevalence of enzyme sensitisation in the baking industry. Methods-A cross sectional study was conducted in four bakeries, one flour mill, and one crispbread factory. Sensitisation to enzymes, flours, and storage mites was examined by skin prick and radioallergosorbent (RAST) tests. 365 workers were tested. The workers were interviewed for work r...
متن کاملDetermination of thiamin and thiamin phosphate esters in blood by liquid chromatography with post-column derivatization.
We demonstrate a liquid-chromatographic method involving post-column derivatization for determining the concentration of thiamin and its phosphate esters in human blood. Blood, erythrocytes, or plasma is deproteinized and centrifuged. Aliquots of the samples are applied to a mu Bondapak C18 column attached to a "high-performance" liquid chromatograph. Addition of potassium ferricyanide/sodium h...
