Freshness & Food safety by nFresh®
At Nanobubbles Spain, we use our advanced patented NB Pulse nanobubble technology through our nFresh® system to transform food preservation. Harnessing microscopic nanobubbles, we help farmers, producers, supermarkets and distributors keep products fresher for longer, cut waste, and improve food safety; all without synthetic chemicals.
What are nanobubbles?
Nanobubbles are extremely small gas bubbles - thousands of times smaller than the width of a human hair - suspended in water. They stay in the liquid far longer than regular bubbles and have extraordinary properties:
Very large surface area for gas transfer
No buoyancy, so they spread evenly in water
Naturally negatively charged, helping to kill microbes
Long lifespan for lasting effects
High internal pressure for deep cleaning and preservation
These features make nanobubbles ideal for safe, chemical-free freshness preservation in food storage and processing.
How It Works
Step 1 - Infusion
Water is infused with Ozone nanobubbles (NBO3)
Step 2 - Even Distribution
Nanobubbles penetrate surfaces and distribute oxygen or ozone evenly.
Step 3 - Microbe Neutralisation
Harmful microbes are destroyed, slowing down spoilage.
Step 4 - Lasting Freshness
Food stays fresher, safer, and better looking for longer.
Our Solutions for the Food Industry
Fruit & Vegetable Shelf Life Extension
Reduce spoilage and waste by keeping produce fresh, crisp, and visually appealing for days longer.
Meat Freshness Enhancement
Keep meat fresher for longer by using Ozone nanobubbles to slow spoilage and inhibit bacterial growth naturally.
Seafood Preservation
Preserve natural taste, texture, and appearance of fish and seafood with gentle nanobubbles treatment and killing the pathogen microbes
