Annotation	Výsledky této studie prokazují, že za optimálních podmínek poskytuje vsádková i kontinuální glycerolýza sojového oleje katalyzovaná imobilizovaným enzymem Candida antarctica (Novozym 435) za použití tercbutanolu jako rozpouštědla produkt s vysokým obsahem monoglyceridů (až 85 %).
Description in English	Enzymatic glycerolysis of soybean oil catalyzed with the commercial lipase catalyst Novozym 435 has been carried out at 45-52 °C in a stirred tank and fixed-bed reactor, using tert-butyl alcohol as a solvent. The effects of reaction conditions on the glycerolysis were evaluated and optimum parameters found for the monoacylglycerol (MAG) production (yield > 85 %). Unlike the batch glycerolysis, in the packed bed reactor, the catalyst retained its activity in long-term operation, regardless of the reaction conditions used. The continuous transesterification of the oil with trimethylolpropane (TMP) afforded a mixture of monoacyl- and diacylglycerols in 90% yield. The high yield of monoacyl-TMP (71 %) along with 24 % of 1- monoacyl- and 5 % of 2-monoacylglycerol gives evidence of the efficiency of the process.
