Oxygen Monitoring in Food & Beverage Nitrogen Blanketing

Verifying Inert Blanket Integrity Over Food & Beverage Storage & Process Tanks OMD-525X

Food and beverage producers use nitrogen blanketing over storage tanks and process vessels to protect oxidation-sensitive products, from wine and juice to edible oils, preventing flavor degradation, color changes, and spoilage caused by oxygen exposure. Confirming the blanket is holding its target oxygen level is essential to realizing these quality benefits.

The OMD-525X trace oxygen analyzer gives food and beverage producers continuous, dependable oxygen monitoring for nitrogen blanketing systems across storage and process applications.

  • Beverage Quality Protection
  • Continuous Online Monitoring

Why Blanketing Verification Matters

A nitrogen blanketing system that appears to be running normally can still allow oxygen ingress due to demand changes or seal issues, and the resulting oxidation can degrade product flavor, color, and shelf life without an obvious external warning sign. Continuous oxygen monitoring in the blanketed headspace confirms the atmosphere is meeting its target specification and protects product quality throughout storage.

Where It's Used

  • Wine, juice, and beverage storage tank blanketing protecting against oxidation during storage
  • Edible oil storage preventing rancidity from oxygen exposure
  • Process vessel blanketing maintaining atmosphere during blending or processing
  • Blanketing system performance audits periodic verification across storage assets

Foire aux questions

Trace oxygen measurement provides a direct indication of oxygen contamination or crossover into the hydrogen stream. Trending the oxygen concentration can help operators identify changes in electrolyser or purification system performance.

A common measurement point is the hydrogen product stream downstream of the electrolyser stack. Additional measurement points may be used before or after drying and purification equipment depending on the process design and monitoring objectives.

Alarm and control limits should be determined based on the electrolyser manufacturer’s specifications, process conditions, applicable standards, and the facility’s safety requirements rather than using a universal oxygen alarm value.
