Abatement
Ethylene

Preserves the freshness of your products longer by breaking down ethylene

Ethylene is a natural gas emitted by fruits and vegetables, which accelerates their spoilage. Titanium dioxide-based photocatalytic technology offers an innovative solution to counter this problem.

The operating procedure is simple.

The air inside the storage rooms is passed through a photocatalytic filter; the light activates titanium dioxide, which degrades ethylene molecules in the air.

This eliminates ethylene and slows down the ripening process of fruits and vegetables.

This is achieved by simply recirculating air internally, without making use of chemicals and with a minimal amount of energy, an investment that pays for itself over time through extended product life and reduced waste.

Ethylene abatement with photocatalytic filtration brings several advantages:

  • It extends the useful life of fruits and vegetables, reducing food waste and increasing profits.
  • It uses no chemicals, ensuring a safe and environmentally friendly process.
  • It requires minimal energy consumption, making it an efficient and cost-effective solution.

Ideal for fresh food professionals who want to optimize the storage of their products.

The process of decay of plants

Ethylene abatement from the air in storage rooms is an inexpensive (and chemical-free) method of extending the shelf life of plant products.

In fact, the phenomenon of ripening is induced by ethylene, also referred to as “ripening hormone,” and is related to the levels of plant tissue respiration and ethylene production, which increase regardless of being on the plant or not.

Ethylene is a light gas (C2H4) n contact with oxygen breaks down into carbon dioxide (C02) and water and produces heat. It can be produced by all organs of the plant, spreads easily in the tissues and disperses in the air.

Climacteric and nonclimacteric fruits:
how ethylene affects storage

Fruits are divided into two categories based on their behavior after harvest:

  • Climacteric fruits: continue to ripen even after being detached from the plant. Examples: bananas, apples, tomatoes, avocados.
  • Non-climacteric fruits: cease to ripen after harvest. Examples: citrus fruits, grapes, strawberries, peppers.

Ethylene, a natural gas emitted by some fruits, plays a key role in ripening.

In climacteric fruits, ethylene accelerates the ripening process, promoting decomposition of starch into sugars, softening of pulp and development of color and aroma.

In nonclimacteric fruits, ethylene has little or no effect on ripening.

Therefore, ethylene can accelerate the ripening of climacteric fruits if it is added artificially (e.g., in the case of imported exotic fruits that are still unripe); or it canslow down ripening if reduced by the storage environment.

Ethylene abatement can be achieved through:

  • Ventilation: good air exchange helps dilute ethylene.
  • Ethylene absorbers: there are products based on natural compounds that capture and neutralize ethylene.
  • Ethylene abatement technologies: systems that degrade ethylene into inert compounds, such as titanium dioxide-based photocatalysis.

PHOTOCATALYTIC FILTRATION

Odor abatement: types and methods

Odor abatement is the process of reducing or eliminating unpleasant odors from an environment.

The perception of a bad odor should not be underestimated because it may not relate exclusively to the well-being aspect, namely perceived annoyance, but could be indicative of the presence of a pollutant in the air and therefore harmful to health.
