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

Proper potato storage is a key factor in the profitability of any agricultural warehouse, cooperative, or logistics center. Inadequate lighting during storage can lead to the formation of solanine, the greening of the tuber, and the appearance of premature sprouts.

In other words: the potato turns green, loses quality, and may not be suitable for sale.

The most effective and sustainable solution today is green LED lighting for potatoes, specifically designed to prevent these issues 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 in excess.
• Product rejection by distributors and large retailers (supermarkets).

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

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, as it:

• Does not activate chlorophyll synthesis, preventing the potato from turning green.
• Drastically reduces solanine formation.
• Inhibits tuber sprouting, even during long-term storage.
• Allows continuous lighting in storage rooms without compromising the potatoes.

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 warehouses

In all these environments, proper lighting makes the difference between a product suitable for sale or one that is discarded.

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. As they do not turn green or sprout, far fewer potatoes are discarded.
• Longer shelf life. Potatoes can be stored for weeks or months while maintaining their quality.
• Energy savings. LED technology consumes little energy and has a long lifespan.
• Reduction of chemical treatments. It reduces or eliminates the use of sprout inhibitors.
• Better operational visibility. It allows working with the lights on without compromising product quality.
