Recobrimento de frutas: como melhorar a conservação pós-colheita e reduzir perdas?

Fruit coatings: how to improve post-harvest preservation and reduce losses?

Oxidized polyethylene waxes used in fruit coating formulations help protect fruit against water loss, contributing to the preservation of its quality until it reaches the market.

Sustainability in the fruit supply chain involves making the most of what has already been produced. After harvest, water loss can compromise the weight and appearance of the fruit, hindering its marketability. Preserving these characteristics is one way to help reduce losses.

Coatings—known as “fruit coatings”—form a film on the surface that helps with moisture retention. Their performance depends on their composition, the method of application, and the conditions during storage and transport.

Protection and biodegradability in the formulation

For those who develop these systems, the choice of raw materials must take into account film formation, compatibility between components, and the desired finish.

MEGH, a Brazilian manufacturer of waxes, emulsions, and dispersions, has developed the MEGH®WAX MPO line for this application. Composed of oxidized polyethylene waxes, it is specifically designed for citrus fruits, such as oranges, lemons, tangerines, and limes.

The technology contributes to the preservation of weight and luster, and it can be used in conjunction with natural waxes and resins.

Another attribute of the product line is its proven biodegradability, as stated in its technical documentation.

Frequently asked questions

What are oxidized polyethylene waxes used for in the coating of fruits?

They contribute to the formation of a protective film that helps reduce water loss and maintain characteristics important to the quality and appearance of the fruits.

Does the use of fruit coatings replace other postharvest practices?

No. The coating complements proper handling. Conditions during storage, transport, and application remain essential for achieving the expected result.

Is a biodegradable wax necessarily of natural origin?

No. Biodegradability and the origin of the raw material are distinct characteristics. The MEGH®WAX MPO line consists of oxidized polyethylene waxes, with the environmental attribute specified in its documentation.
