South Korean Scientists Develop DNA Barcode to Replace Traditional Barcodes

South Korean scientists at Ekhua University have developed a DNA barcode system to replace traditional barcodes. This system uses DNA sequences sprayed on products, making it difficult to forge. The DNA is protected by an inorganic bubble, preventing degradation. This nano DNA barcode system (NDBS) enhances consumer safety by ensuring food authenticity and identifying contamination.

What is the primary advantage of using DNA barcodes over traditional barcodes?

• They are more difficult to forge.

• They are more colorful.

• They can be easily removed.

• They are cheaper to produce.

How are DNA barcodes applied to products?

• They are attached with glue.

• They are printed on paper.

• They are sprayed on the products.

• They are embedded in plastic.

What innovation did the ECUA University team achieve with DNA barcodes?

• They made them edible.

• They made them cheaper to produce.

• They encapsulated DNA in an inorganic bubble.

• They made them colorful.

What is one of the potential benefits of the nano DNA barcode system?

• It can make food taste better.

• It can identify contaminated produce.

• It can increase the shelf life of products.

• It can reduce packaging waste.

Why is there public mistrust about food labels in South Korea?

• Labels are too colorful.

• Labels are too small to read.

• Labels are written in a foreign language.

• Imported foods are often mislabeled as domestic.
