In distillery fermentation, nutrient solutions play a critical role in supporting yeast metabolism and overall fermentation efficiency. Traditionally, inorganic additives like urea and DAP (Diammonium Phosphate) have been used to supply essential nitrogen and phosphorus for yeast growth. However, the industry is shifting toward organic bio-nutrient solutions, which offer significant environmental and production advantages over their inorganic counterparts.
Inorganic nutrients, such as urea and DAP, provide quick and inexpensive sources of nitrogen and phosphorus but come with several drawbacks. Excessive use of these chemicals can lead to inconsistent yeast health, increased fermentation stress, and higher byproduct formation, potentially impacting both the quality and yield of alcohol. Additionally, inorganic nutrient residues can harm wastewater systems, contributing to environmental pollution and increasing wastewater treatment costs.
