Yes. With a powerful 365 nm LED lamp, suspect fruit that may contain aflatoxin glows greenish-yellow even in daylight. The glow is still clearest in a dark or dimly lit place.

Why were dark rooms used in the past?

The glow under UV light is seen against the surrounding light. The brighter the surroundings, the fainter the glow. Old fluorescent UV tubes were weak, so the glow could only be picked out in a dark room. That is why most dried fig processors still sort in dark rooms.

What has LED changed?

AFLALED produces 365 nm light directly with powerful LEDs, delivering 12 mW/cm² at 30 cm. With strong light, the glow can be seen by eye in daylight too. You can see this in our video, filmed in daylight in front of a warehouse.

You can do your checks in a dark room, in bright conditions and even in direct sunlight.

This matters for businesses without a dark room, or for buyers who want to see a lot before it enters the warehouse. Checking the goods at the door lets you spot a problem lot before you accept it.

Tips for better results in daylight

• Hold the lamp 20 to 40 cm from the product.
• Keep the sun behind you and cast your own shadow over the crate.
• If possible, choose a shaded spot such as under an awning, inside the truck or at the warehouse door.
• Spread the fruit in a single layer so that pieces do not overlap.

Which setting for which job?

A daylight check is a quick first look. It suits goods intake, the back of a truck, the drying yard or the orchard. For detailed sorting and work on the belt, a dark or shaded section is preferred, because sorters look for the same glow for hours.

Whatever the setting, UV sorting is a pre-sorting step. A glowing piece is suspect fruit that may contain aflatoxin; the final result comes from the laboratory.
