Abstract: In the manuf. of lactic acid, it was found by lab. expts. on a larger scale that sucrose (I) can be extd. as Ca saccharate (II) by lime from beet molasses dild. to 6% I concn. II is decompd. by satn. with CO₂ into I and CaCO₃ (satn. cake). I soln. is fermented by Lactobacillus delbr.ovrddot.uckii into lactic acid, clarified by lime and Ca lactate is crystd., which can be changed by H₂SO₄ into lactic acid. This process decreases the manuf. cost by 30%.
