<p>Researchers have developed a new method of keeping strawberries fresher for longer: controlled pulses of UV light have been shown to be effective in preventing decay.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding">Studies have shown that long exposure to low irradiance ultra-violet light at low temperatures and high humidity can delay the spoilage of strawberries, according to the Digital Journal.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding">An innovative device has been designed incorporating light-emitting diodes (LEDs) that emits UV rays at the same wavelengths found in sunlight passing through the earth’s atmosphere.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding">The treatment has been shown to double the shelf life of the berries to nine days without mold. Berry freshness was assessed by darkness of the fruit, weight, moisture content, concentration of select phytochemicals, visible damage, and mold growth.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding">The innovation was developed by researchers at the U.S. Department of Agriculture's (USDA) Food Components and Health Laboratory in Beltsville, Md., and Sensor Electronic Technology, Inc.
