Features
The FERMAID E® is a complex nutrient that once added
the wine provides the yeast nitrogen easily assimilable and
as essential growth factors for their
development and multiplication.
• compensates for deficiencies in nutrients (nitrogen easily
assimilable amino acids) and growth factors (sterols,
long chain fatty acids).
• It prevents the action of microbial inhibitors (fatty acids,
antibiotics) as well as a source of toxic substances
Exogenous (fungicides).
• Decreases the effect of the absence of colloids, balancing
musts very clarified.
• Allows a more regular and rapid kinetics of fermentation.
• Prevents metabolic deviations by the yeast, decreasing
production of volatile acidity and sulfur compounds.
• Increase the production of glycerol and decreases compounds
carbonyl, which combine with the sulfur, yielding
a better relationship free sulfur / sulfur combined.
Application field
Why look for the optimum development of yeast?
• For best performance of the inoculated yeast.
• To prevent fermentation stops.
• To remedy the fermentation stops or fermentations
slow.
• To avoid the formation of undesirable compounds (H2S).
The fermentation performance of the yeast is largely
conditioned by the presence of assimilable nitrogen, vitamins,
oxygen, arginine, mineral salts, unsaturated fatty acids and
sterols.
This large number of variables increases the likelihood of
occurrence of a shortage of one of these elements alone
can cause a stuck fermentation.
Composition
The unique and specific formulation E® is connected to FERMAID
a unique production method of inactive yeast that
constitute the "active ingredient" product, which is part of the new
generation fermentation activators.
The roles of each of the constituents are FERMAID E®
described below:
• inactive yeast cells: The inactive yeast is a
a source of amino acids, polysaccharides, chain fatty acids
long, sterols, vitamins and mineral elements vital to
cell activity. Its walls adsorb substances
toxic and inhibitory.
• diammonium phosphate (DAP) and diammonium sulfate, What do
part of easily assimilable nitrogen fraction (NFA). THE
N availability problems and avoids the fermentation
formation of aromas and unpleasant flavors.
• Silica Gel: exerts a supportive effect on the yeast.
• Thiamine: That is added in the form of hydrochloride. Thiamine
active alcoholic fermentation, increasing the population and
extending the duration of its activity. It acts as a regulator
in the latter stages of fermentation, limiting the production of
ketone compounds and aldehydes by the yeast.
Important Note: The transport of amino acids and the ammonium ion
wort occurs to the cell (yeast) through the membrane
plasma. For amino acids, this transport mechanism is
performed by an enzyme - the permease. Research
They demonstrated that the efficacy of this transportation system is
dependent on the concentration of sterols and fatty acids
unsaturated plasma membrane (Calderbank et al, 1985;
Prasad and Rose, 1986). The FERMAID E® by offering these principles
nutritious, improves the nitrogen nutrition of the yeast,
optimizing the fermentation efficiency.
Application Dose
• 20-60 g / hl: It is the recommended dose of FERMAID E®
How to Use
The FERMAID E® optimizes the fermentation phase, in response
the metabolic requirements of the yeast.
Two different types of treatment may be prescribed:
APPLICATION 1:
BREW START (FERMAID E® + LSA)
For a quick start of the alcoholic fermentation.
It offers three components essential to the effectiveness and longevity of
yeasts.
• It stimulates the multiplication of yeast (nitrogen)
• Enables the alcoholic fermentation (Thiamine)
• supporting effect and reducing the amount of toxins
APPLICATION 2: DURING THE BREW (FERMAID E® + Oxygen)
Oxygen: Apply after a drop of 10-20 points
density.
It allows the synthesis of sterols membrane.
• cellular permeability factor.
• Resistance to ethanol
• Ensures more complete fermentation of sugars.
FERMAID E®
: Apply after a drop of 30-40 points
density
• To ensure complete fermentations.
• Reactive transport of sugars (nitrogen).
• It stimulates the synthesis of sugar transport proteins to
within the yeast.
APPLICATION 3:
STOPS FOR BREW
In this situation the FERMAID E®
reinforces the success of the resumption of
fermentation process.
