Green LED light for potatoes: how to prevent solanine and sprouting during storage

The proper preservation of potatoes is a key factor in the profitability of any agricultural warehouse, cooperative, or logistics center. Inadequate lighting during storage can cause the formation of solanine, the greening of the tuber, and the appearance of premature sprouts. In other words: potatoes turn green, lose quality, and may become unsuitable for sale.

The most effective and sustainable solution currently available is green LED lighting for potatoes, specifically designed to prevent these problems without the need for chemical treatments.

What is solanine and why does it appear in potatoes?

Solanine is a natural substance (a glycoalkaloid) that potatoes produce when exposed to certain wavelengths of light, especially white, blue, or sunlight.

Its main consequences are:

• Appearance of green areas on the potato skin.

• The taste becomes bitter.

• Increased toxicity if consumed excessively.

• Product rejection by distributors and large retail chains (supermarkets).

Light control during storage is therefore an essential aspect to guarantee the commercial and sanitary quality of the product.

Other factors influencing potato sprouting

In addition to lighting, there are other factors that can accelerate or slow down potato deterioration during storage.

One of the most important is ethylene, a natural gas released by products such as onions, apples, or bananas. This compound acts as a plant hormone that accelerates ripening and sprouting.

For this reason, storing potatoes together with onions can encourage the appearance of sprouts and increase solanine formation, reducing their quality and shelf life.

On the other hand, other foods such as garlic contain sulfur compounds like allicin, which may help to partially inhibit sprouting.

Although these factors are relevant, in professional environments the most decisive element remains lighting control, where green LED lighting for potatoes plays a key role in preventing greening and extending product preservation.

Why does green LED light prevent solanine formation?

Various scientific studies and real-environment tests have shown that green LED light (approximate wavelength of 520-540 nm) provides many benefits because it:

• Does not activate chlorophyll synthesis, preventing potatoes from turning green.

• Drastically reduces solanine formation.

• Inhibits tuber sprouting, even during long-term storage.

• Allows continuous lighting in storage rooms without compromising potato quality.

Unlike conventional lighting, green LED lighting for potato storage is specifically designed to protect the product over long periods.

Applications of green LED lighting for potato storage

Green LED lighting is especially recommended for:

• Cold storage rooms.

• Agricultural warehouses and cooperatives.

• Fruit and vegetable logistics centers.

• Processing and packaging plants.

• Supermarket and wholesale storage facilities.

In all these environments, proper lighting makes the difference between a product suitable for sale and a discarded product.

Advantages of using green LED light in agricultural warehouses

Using green LED lighting provides many benefits, even for people without technical knowledge:

• Less product loss. Since potatoes do not turn green or sprout, far fewer potatoes are discarded.

• Longer preservation time. Potatoes can be stored for weeks or months while maintaining their quality.

• Energy savings. LED technology consumes little energy and has a long service life.

• Reduction of chemical treatments. Reduces or eliminates the use of sprout inhibitors.

• Improved operational visibility. Allows work under lighting conditions without compromising product quality.

Is installing green LED lighting for potatoes profitable?

Yes. From an economic point of view, green LED lighting:

• Reduces losses caused by green potatoes.

• Decreases commercial returns.

• Improves the quality of stored products.

• Optimizes energy costs.

• Increases stock profitability.

In medium and large installations, the return on investment is usually achieved within a short period thanks to reduced waste.
