jim_appleyard Posted May 15, 2004 Share Posted May 15, 2004 Does anyone know a teaspoon equivalent for ascorbic acid? Thanks, Jim Link to comment Share on other sites More sharing options...
the_macman Posted May 15, 2004 Share Posted May 15, 2004 45 oranges :-) They say it's about 65mg/orange. The density of ascorbic acid is 1.65. A teaspoon is 5mL or 3g of ascorbic acid. :P Link to comment Share on other sites More sharing options...

silent1 Posted May 15, 2004 Share Posted May 15, 2004 Something is wrong with Macman's figures -- if in fact ascorbic acid has a density of 1.65 (g/cm^3), then 5 mL (== 5 cm^3) volume would equate to about 8.25 g, not 3 g. Of course, the discrepancy could be that the density given is for a solid crystal rather than for granulated/powdered material with a porosity determined by the shape of the granules -- I don't know for sure, and I don't know which figure is correct, if either, but I do know that 5 mL per teaspoon is correct, give or take a tiny fraction, and that's 5 grams of sugar (sucrose) as well, even though the individual crystals are much denser than water.

al_divenuti Posted May 16, 2004 Share Posted May 16, 2004 You are on the right track... You will want to use the material's bulk density to compute the mass of material contained in a teaspoon. This accounts for the granule effect you mention above. Remember that pure water is generally 1000 kg/m^3 (or 1kg / 1000 ml) and the necessary computations should be relatively easy. Keep in mind that bulk density figures for commercially-available powders can vary quite a bit - sometimes 15 or 20 %. Link to comment Share on other sites More sharing options...
peter_svensson Posted May 16, 2004 Share Posted May 16, 2004 It's 4g/tsp. Link to comment Share on other sites More sharing options...
jim_appleyard Posted May 17, 2004 Author Share Posted May 17, 2004 Incase anyone was wondering, I really can spell "teaspoon", I just can't type it very well. My fingers just can't keep up with the blazing brain activity! Link to comment Share on other sites More sharing options...
