摘要： The present invention relates to a process for the fermenta­tive preparation of lactic acid, by allowing a sterilized growth medium to be continuously fermented in a reaction vessel by a culture of bacilli of the genus Bacillus , which form lactic acid, keeping the pH of the reaction mixture at 3 to 9 with an aqueous solution of XOH (where X is NH₄ or a metal whose hydroxide and whose salt of lactic acid are watersoluble), subjecting the fer­mented reaction mixture to an ultrafiltration, recycling the reten­tate to the reaction vessel, and concentrating the permeate and subsequently subjecting it to an electrodialysis wherein bipolar membranes are used, in which process the lactate is decomposed into the lactic acid and XOH.

摘要： Method for the preparation of esters of a non-reducing sugar and one or more fatty acids in a relatively short time to obtain a sugar product in a high yield and with a desired purity, and, at the same time, restricted investment costs for equipment. Said method is based on the transesterification of at least one fatty acid alkyl ester with a non-reducing sugar in the presence of a transesterification catalyst and, if appropriate, an emulsifier and is characterized by subjecting the starting compounds to a "high shear" mixing treatment at a temperature which is at least equal to the melting temperature of the used fatty acid alkyl ester result­ing in a stable homogeneous dispersion, which is then exposed to an elevated temperature in the range of 100-180°C and a reduced pre­sure of at most 0.5 Bar.
