    Abstract: Methods of use of carbonic acid esters corresponding to general formula I: ##STR1## in which R.sup.1 is an alkyl radical derived from an aliphatic saturated primary alcohol containing 1 to 22 carbon atoms and R.sup.2 is an alkyl radical derived from an aliphatic, saturated primary alcohol containing 1 to 8 carbon atoms and/or has the same meaning as R.sup.1 and n is a number of 2 to 20 while m is 0 or has the same meaning as n, as foam control agents for the sugar beet or potato-processing food industry and/or in fermentation processes are provided. In the industrial processing of sugar-containing plant juices, as carried out on an industrial scale in the case of sugar beet, particular difficulties are caused by excessive foaming in the defecation units, during transport of the beet, in the diffusors and in the carbonizing tanks and before the evaporators, thus, use of the esters in these processes is advantageous. Other areas of use include the production of potato products, such as chips or French fries, in the production of baker's yeast using molasses or other industrial fermentation processes, such as the production of medicaments, to reduce foaming to a level which does not interfere with the industrial production process.

    Abstract: Disclosed herein are antifoaming agents for fermentation which include, as active ingredient at least one of (a) a reaction product obtained by adding at least one alkylene oxide to a mixture of a fat and/or oil with a trihydric or still higher polyhydric alcohol, or (b) a compound represented by the following general formula (1): ##STR1## wherein n stands for a number of 2-50, R.sup.1, R.sup.2 and R.sup.3 mean individually a hydrogen atom or an acyl group having 2-31 carbon atoms, x denotes an alkylene group having 2-4 carbon atoms, and m1, m2 and m3 are individually a number of 0-200, an L-amino acid-producing medium containing either one of these components, and a production process for L-amino acids making use of this medium. The use of this antifoaming agent permits the quick, sure and durable suppression of bubbling during incubation, and the overall production of the L-amino acid is significantly improved.
