Micro-Nano Ozone Bubble Cleaning Technology: Effective Sterilization, Pesticide Removal, And Extended Freshness for Fruits & Vegetables

Micro-Nano Ozone Bubble Cleaning Technology: Effective Sterilization, Pesticide Removal, and Extended Freshness for Fruits & Vegetables
Fresh-cut fruits and vegetables, prized for their convenience and hygiene, face significant challenges from microbial contamination and pesticide residues, which directly impact quality and shelf life. Traditional cleaning methods like brush scrubbing risk damaging delicate greens, while chlorine-based sanitizers may produce carcinogenic byproducts. Conventional ozone water, with low solubility and instability, fails to meet stringent sanitization needs.

Micro-Nano Ozone Bubble Technology revolutionizes this landscape by transforming ozone gas into micro-nano bubbles (100 nm–10 μm), drastically enhancing gas-liquid contact surface area. This innovation boosts ozone solubility by over 40% compared to traditional aeration methods, effectively addressing ozone’s rapid decomposition issue.

The technology penetrates crevices and folds of produce, achieving 360° cleaning. Lab tests confirm:

• ∙99.99% elimination of E. coli and Staphylococcus aureus using 1–2 mg/L ozone bubbles (5–8 min treatment)

• ∙80%+ pesticide residue removal (e.g., 99.99% reduction in Salmonella on spinach)

• ∙Compliance with FDA food safety standards (zero chemical residues post-treatment)

Advanced System Integration:
A dual-stage cleaning process (pre-rinse + ozone micro-bubble refinement) combines smart controls for 30% water/energy savings and 1-ton/hour processing capacity. Case studies demonstrate:

• ∙Extended leafy vegetable shelf life by 2–3 days

• ∙25% reduction in post-harvest loss

• ∙35% annual operational cost savings

Adopted by global supermarkets and export-oriented fruit and vegetable processing plants, this technology sets a new benchmark for sustainable freshness preservation.
