The aim of the present work was to assess the reusability of
S. cerevisiae immobilized on P. chrysogenum in the fermentation of
raisin must from Pedro Ximenez variety with a view to improve the
process of sweet winemaking and to obtain a natural sweet wine performed as follows: before biocapsules were used, they were
easily removed from the production medium using a sterilized
strainer and then were washed twice with sterile distilled water at
4 C and then with fresh must at the same temperature.
