Scientists have found that violet LED light can keep fresh-cut apples from turning brown. In a recent study, researchers at Shenyang Agricultural University used violet light on apples to make them stay fresh longer without chemicals. This discovery is very promising.
Violet LED treatment greatly preserves apple freshness and reduces browning.
During the experiment, researchers exposed apples to 700 lux violet LED light for four days, while some apples were kept in darkness as a comparison. The apples treated with violet light stayed bright in color and had more antioxidants because the light stopped certain enzymes that make them brown.
The study shows that this green method can be easily used in food processing to save more food and make fresh-cut fruits more appealing in stores. Researchers think this treatment could also help other fruits like pears, melons, and pineapples, making a big difference in the industry by giving people the quality and convenience they want.
Recap: Violet LED light prevents browning and keeps apples naturally fresh.
Final Thoughts: This no-chemical method could change how we store produce and attract customers, pointing to a sustainable future for the industry.
