OENOVEGAN® MICRO FA is a 100% natural biocontrol product developed to slow down the growth and reduce the population of spoilage microorganisms naturally present on grapes. It is an effective alternative to SO₂ due to its antifungal properties.
OENOVEGAN® MICRO FA enables you to control of the microbiological diversity of musts thanks to the synergy between two active ingredients: activated chitosan and yeast hulls.
- Chitosan is a polymer of the glycosaminoglycan family, derived from the chitin contained in the cell walls of microorganisms such as Aspergillus niger. Its "activated" form has a high degree of deacetylation and gives it more reactivity: positively charged in an acidic environment (pH < 5.5), its molecule reacts by means of electrostatic reactions between the numerous amine functions at its surface and the negatively charged compounds are found in the walls of spoilage microorganisms, causing dysfunction in their membrane and resulting in their death.
- Yeast hulls have detoxifying properties and eliminate certain undesirable molecules
(unsaturated fatty acids, pesticides, etc.) contained in the must.
OENOVEGAN® MICRO FA is an easy-to-use solution thanks to its granulated formula, which enables fast rehydration and results in a homogeneous product that ensures effective action on the entire grape harvest or treated must.
