Nutrient with high anti-oxidant action used for beer fermentation
during propagation stage.


Yeast extract, specifically selected by the biotechnological unit of AEB to optimize yeast development
during propagation stage while protecting the yeast with natural anti-oxidant glutathion.
Fermoplus GSH comes from a specific Saccharomyces cerevisae selected to feed low fermentation yeast.
Its particulary efficient within the first propagation tank, and, can be added until the last propagation
stage according to situation.

High anti-oxidant capacity: its metabolic purpose during fermentation. The innovative characteristic
of Fermoplus GSH is its capacity to bring a large amount of glutathione. The yeast strain, which
produces naturally glutathione and the AEB manufacturing protocol maximise the quantity of glutathione.
Glutathione, an atypical tripeptide (L-Glutamyl-L-cysteinylglycine), is the most powerful natural biological
reducer existing, protecting yeast cell against free radicals and oxidation damages.

In case of dry yeast utilisation, during rehydratation, living cells consume oxygen for multiplication but
do not have the capacity to produce glutathione. Fermoplus GSH allows them to be protected against
oxidative stress and synthesise the glutathione afterwards when propagation begins. The concentration
reaches up to 9% of dry matter.

In the first stages of fermentation, Fermoplus GSH nutrient are widely consumed and the concentration
of glutathione decrease a lot. This is the exponential stage. The amount of glutathione increase at the
end of fermentation, the few dying cells releasing this fraction.

The protection objective of the yeast during exponential stage is to guaranty an identical quality cells,
whatever the generation it is. Protecting against oxidation the yeast strain and other aminoacid will
prevent off flavour to appear.


Yeast hulls, autolysates of yeast, thiamine hydrochloride (vitamin B1).


From 10 to 50 g/hL in rehydration stage. In case of low vitality of strain, add 5 g/hL into the fermentation
tank. In case of low vitality of strain, add 5 g/hL into the fermentation tank.


Hydrate in sterile water (1:10) or directly add to the fermentation medium during the rehydration stage.


Store in a cool dry place, away from direct sunlight and heat.
