Vinasse

The word vinasse comes from the Latin vinacaeus and originally meant wine yeast. At the beginning of the 20th century, vinasse became the common expression for thickened, fermented sugar beet molasses in Europe. Like molasses, vinasse is a honey-like, dark brown syrup that is produced as a by-product after molasses has been fermented. Famous promoter of the use and marketing of vinasse in German-speaking countries was Wilhelm Lewicki . As early as 1845, Justus von Liebig (an ancestor of Wilhelm Lewicki) suggested using the then nameless by-product of alcohol production (through beet molasses fermentation) to fertilize sugar beet fields in order to supplement the missing potassium in the soil.

composition

The composition varies depending on the origin of the molasses ( sugar cane , sugar beet ) and the fermentation process.

Rohr vinasse from alcohol production

• organic dry matter approx. 61%
• Crude protein (in% of DM) approx. 11%
• Ash content (in% of DM) approx. 29%
• Sugar content (in% of DM) approx. 13%

Beet vinasse from citric acid production

• organic dry matter approx. 61%
• Crude protein (in% of DM) approx. 26%
• Ash content (in% of DM) approx. 39%
• Sugar content (in% of DM) approx. 7%

Beet vinasse from yeast production

• organic dry matter approx. 54%
• Crude protein (in% of DM) approx. 36%
• Ash content (in% of DM) approx. 38%
• Sugar content (in% of DM) approx. 2%

Other ingredients (sugar beet vinasse)

• N total 3–4.5%
• K ₂ O 6-9%
• P ₂ O ₅ 0.2-0.5%

Areas of application

Use in animal feed

Vinasse can be used in animal feed for protein enrichment, as a binding agent / dust brake and as an appetizer. Beet vinasse with a high protein content is particularly suitable as a feed additive (4–5%) for ruminants. Due to the lower ammonium tolerance, admixtures of approx. 2% have proven effective for pigs or poultry.

Use as a fertilizer

The content of partially organically bound minerals (NPK) makes beet vinasse a valuable organic fertilizer (e.g. for orchids). Due to the residual sugar content, vinasse also promotes the rotting of straw and the fertility of the soil by enriching the soil with soil microorganisms . Due to its higher salt content, Rohr-Vinasse is less suitable for fertilization, so fertilization should take place no more than about every three years. Too frequent application of pipe vinasse can reduce soil fertility due to salinization.
