Microbial Control of Fresh Produce using Electrolyzed Water

Microbial Control of Fresh Produce using Electrolyzed Water

The demand for fresh salad vegetables, such as iceberg lettuce, has increased worldwide in recent years. Numerous sanitizers have been examined for their effectiveness in killing or removing pathogenic bacteria on fresh produce. However, most of the sanitizers are made from the dilution of condensed solutions which involves some risk in handling and is troublesome. A sanitizer that is not produ...

Microbial reduction and storage quality of fresh-cut cilantro washed with acidic electrolyzed water and aqueous ozone

Efficacy of decontamination treatments in reducing microbial populations on cilantro and in improving its storage quality was investigated. Fresh-cut cilantro samples were washed with one of the five treatments: tap water, acidic electrolyzed water (AEW), aqueous ozone, chlorinated water, and aqueous ozone followed by AEW (sequential wash). Treated cilantro was packaged in polyethylene bags pre...

Enzymatic browning and its control in fresh-cut produce

Purpose of review: Enzymatic browning of fruits and vegetables during postharvest handling and processing degrades the sensory properties and nutritional value and discourages consumer purchase of fresh-cut products. Consequently, enzymatic browning results in significant economic losses for the fresh produce industry. This paper discusses the biochemistry of enzymatic browning, and focuses on ...

Hydrogen production from inexhaustible supplies of fresh and salt water using microbial reverse-electrodialysis electrolysis cells.

There is a tremendous source of entropic energy available from the salinity difference between river water and seawater, but this energy has yet to be efficiently captured and stored. Here we demonstrate that H(2) can be produced in a single process by capturing the salinity driven energy along with organic matter degradation using exoelectrogenic bacteria. Only five pairs of seawater and river...
