At Oenobrands, manufacturing our yeast derivates requires meticulous and technical expertise. Here’s a quick overview of the process:
We grow selected yeast cultures under regulated conditions to ensure optimal growth and vitality. After fermentation in a nutrient-rich media, these cultures grow and flourish to maximum density and vitality. After fermentation, the facility staff collect active yeast cells to make our concentrated yeast cream.
Active yeast is made inactive by heating it before drying it. It adds nitrogen, minerals, vitamins, and trace elements to the must, promoting alcoholic fermentation and yeast development. It promotes yeast survival at the end of fermentation, releases polysaccharides, and enhances volume and mouthfeel.
Also known as yeast hulls, these are the insoluble components of yeast walls that do not contain cytoplasm. They are composed of polysaccharides, proteins, lipids, and a little chitin. Yeast cell walls absorb harmful compounds and offer growth and survival factors (sterols, unsaturated fatty acids), optimising fermentation efficiency and avoiding stuck or sluggish fermentations.
Saccharomyces cerevisiae yeast biomass is autolyzed or heated under controlled conditions to produce autolysed yeast. It releases valuable intracellular components like proteins, amino acids, and nucleotides. These contain more free amino acids than inactive yeast.
Mannoproteins are naturally present as they are the smallest part of the yeast cells walls. Mannoproteins consist of both proteic and carbohydrate moieties (mannose and peptide chains). They constitute a large group of molecules with a broad diversity of types in terms of size, charge (phosphorylation degree), and proteic or carbohydrate composition and ratio. This structural diversity induces different functional properties.
Thanks to our knowledge of yeast and mannoprotein biochemistry, our expertise in production, extraction, and purification, as well as our know-how in oenological applications of mannoproteins, we can provide selected and dedicated mannoprotein-based solutions.
As Oenobrands, we provide qualitative and selected mannoprotein-based solutions, like Claristar®, Final touch® POP, Final touch TONIC and Final touch GUSTO.
