Micro Guard - Perdomini-IOC

Micro Guard
STABILIZATION
To control bacterial flora before and after malolactic fermentation.
Oenological applications
Micro Guard is an innovative completely allergen free and GMO
free solution, for controlling bacterial flora before and after malolactic fermentation. Micro Guard is a new natural and vegetable technological aid consisting in an innovative mixture of
polysaccharides derived from chitin.
• Stabilizes red wines after MLF avoiding the onset of the
classic wine diseases
• Prevents MLF where unwanted on white and rosé wines.
• Allows the proper conservation of the Charmat bases wherever low levels of SO2 are required for optimal start of fermentation
• It is a major alternative for those who want to work with low
doses of sulphur.
• Helps to reduce the appearance of volatile acidity due to
the presence of acetic bacteria
• It has a clarifying/clearing action
Instructions for use
Eose in water or wine in a volume equal to 5 times its weight
mixing the solution to obtain a homogeneous suspension (no
lumps).
Add the suspension progressively into the mass to be treated
and proceed with the mixing of same. Leave the product for a
minimum of twenty days of contact.
The kinetics of the bacterial population is best carefully
monitored by a specialized laboratory. *
* Our scientific technical service is available to give support to
the client in order to assess the initial conditions of the wine to be
treated, the ideal dosage to be used and monitor the effectiveness
of treatment over time through chemical and microbiological testing.
Dosage
25-60 g/hl Disperse Micro Guard in a volume of water or wine
equal to 5 times its weight, in order to obtain a homogeneous
suspension.
Packs and storage conditions
Present in many living organisms, chitin is the most abundant
polysaccharide after cellulose.
Among the polysaccharides of interest for humans, chitin and
its main derivatives (chitosane and chitin-glucan) play an increasingly more important role.
In 2003, KitoZyme innovated by developing a manufacturing
process based on the use of a source of chitin of non-animal
but rather plant origin. KitoZyme and Perdomini are working together to propose an innovative collage of products, in line with
market expectations.
In 2009, only chitin derivatives of vegetable origin, this new
biotechnological tool, were recommended by the OIV and were
authorized for use by the European Community in 2010.

Delay or blockage of mlf in white and rosé wines
In white and rosé wines, MLF is undesirable in many cases, because it substantially changes the flavour of the product compromising organoleptic objectives of freshness. In sparkling wines produced using the Charmat method it is essential to maintain the base wine intact, which
will be used for the second fermentation. The presence of lactic bacteria at this stage is very risky because it compromises the integrity of
the mass.

As the result of the strategies and tools developed by Perdomini for the control of oxidation and microbiological contamination, during the pre-fermentation, fermentation and aging stages, Micro Guard is a strong tool for the reduction
of SO2 concentrations.
