Use of yeast biocapsules as a fungal-based immobilized cell technology for Indian Pale Ale-type beer brewing
Abstract
Immobilized cell technologies (ICT) have been used in wort fermentation, beer maturation, or production of alcohol-free or low-alcohol beer. The purpose of ICT is to restrict intact cells to a specifc location while allowing biological function. It improves cell stability, operational fexibility, and control in brewing, as well as ease in executing continuous operations. We investigated the use of yeast biocapsules for Indian Pale Ale (IPA) type beer wort fermentation, a novel ICT in brewing. Yeast biocapsules are a spherical yeast immobilization system in which yeast cells are encapsulated and connected to the hyphae of an inactivated hollow flamentous fungus pellet. Fermentations with yeast encapsulated in alginate beads, as the standard immobilization practice, and in free (non-immobilized) forms were carried out in parallel. We found that yeast biocapsules are a better option for cell reutilization than alginate beads, but worse for beer must clarity. Beer brewed with yeast biocapsules difered in concentration for fve volatile compounds (acetaldehyde, diacetyl, ethyl acetate, 1,1-diethoxyethane, and isoamyl alcohol) and three sensory characters (persistency of the foam, malt, and yeast character).
