Speedferm
Used prior to the alcoholic fermentation of dry active yeasts, SIHA SpeedFerm yeast nutrient is a special yeast nutrient mixture made from inactive yeasts, containing vitamins (e.g., pantothenate, biotin), minerals (magnesium, zinc, manganese), and amino acids.
SIHA SpeedFerm yeast nutrient contains micronutrients that have a targeted effect prior to alcoholic fermentation. Especially after rehydration, when the enzyme and substrate traffic systems have been formed, yeast cells are able to absorb micronutrients and accumulate them intracellularly. This provides continuous access to this intracellular nutrient pool during alcoholic fermentation. Optimum yeast nutrition with SIHA SpeedFerm yeast nutrient ensures a safe final degree of fermentation and a higher proportion of living cells up to the end of alcoholic fermentation.
Features and Benefits
The specific advantages of SIHA SpeedFerm yeast nutrient:
- Improves nutrient supplementation after rehydration and during changes in pure yeast temperature prior to alcoholic fermentation.
- Reduces the formation of H2S during alcoholic fermentation.
- Promotes cell reproduction.
- Increases the proportion of active cells during the entire fermentation process up to the end of fermentation.
- Ensures a better final degree of fermentation, particularly during cold fermentation.
Product Applications
SIHA SpeedFerm yeast nutrient is used after the rehydration of dry active yeasts. It is best applied during the change in temperature between the rehydrated dry active yeasts (temperature < 86 °F (30 °C)) and the tank to be inoculated (e.g., < 68 °F (20 °C)). The product can be added directly without being dissolved.
SIHA SpeedFerm yeast nutrient specifically aids the dry active yeast and is not a substitute for nitrogen dosage prior to fermentation or during alcoholic fermentation. The yeast should be additionally supplied with nutrients during alcoholic fermentation using:
- SIHA Fermentation Salt yeast nutrient (diammonium phosphate)
- SIHA Fermentation Salt Plus yeast nutrient (diammonium phosphate, SIHA Vitamin B1 yeast nutrient, cellulose) for intensively pre-clarified musts
- SIHA PROFERM™ Plus combined yeast nutrient preparation
