Abstract

Apple, apricot, cherry and plum meal were prepared from the seeds or kernels of mature garden fruits. The preparations as well as almond meal were used as the source of (R)- oxynitrilase for the synthesis of aliphatic and aromatic cyanohydrins in diisopropyl ether in the presence of 0.1 M tartrate buffer [2%(v/v), pH 5.4]. Apple meal as the most favourable of the enzyme preparations accepts also sterically hindered aldehydes (eg, pivalaldehyde) ...
