However, in recent days, the scandalous story about food, from the inside of pork intestine to the smelly frozen chicken feet has shocked many people. The concern about food safety has long been a constant concern for consumers. Now, after fake medicine, fake milk, fake inside of pork intestine, fake chicken eggs, the worry has flared up again and caused outrage.

Counterfeit products, soaked in toxic chemicals, not only deceive consumers but also pose a risk of poisoning, digestive damage, and even cancer if accumulated over a long period of time. Distinguishing between real and fake by senses is extremely difficult, even with characteristics such as elasticity, color or texture.

Never before have consumers expected as much dedication and determination from authorities as they do today.
