Water Molecule: pH 5.0-7.0, Purity >99.9%

Component Specifications

Definition

A diatomic molecule composed of two hydrogen atoms covalently bonded to one oxygen atom (H₂O), purified to meet food-grade standards for use as a solvent, reaction medium, and dilution agent in ethanol solution manufacturing for food applications. Must comply with stringent purity requirements including microbial limits, chemical contaminants, and mineral content specifications.

Working Principle

Acts as a universal polar solvent that dissolves ethanol and other food-grade compounds through hydrogen bonding and dipole interactions. Facilitates chemical reactions, heat transfer, and mass transfer in ethanol production processes while maintaining product safety and quality standards.

Materials

Purified water meeting food-grade specifications: USP Purified Water or equivalent standards, conductivity <1.3 μS/cm, total organic carbon <500 ppb, microbial limits <100 CFU/mL, endotoxin <0.25 EU/mL

Frequently Asked Questions

What purity level is required for water in food-grade ethanol production?

Water must meet USP Purified Water standards with conductivity below 1.3 μS/cm, microbial count under 100 CFU/mL, and total organic carbon less than 500 ppb to ensure food safety and product quality.

How does water quality affect ethanol solution stability?

Impurities in water can catalyze unwanted reactions, promote microbial growth, alter ethanol concentration accuracy, and affect final product taste, appearance, and shelf life in food applications.

What testing methods verify water suitability for food-grade ethanol?

Regular testing includes conductivity measurement, microbial enumeration, total organic carbon analysis, heavy metal screening, and endotoxin testing following USP and ISO methodologies.
