Some people were puzzled. "Boss Lu, do you have eyes that see through everything? You took one look and knew something had been added to the food?"
"Boss Lu is a professional. Experts see what insiders see—some things can be spotted at a glance, but outsiders like us can't tell!"
Lu Qin had always given people a reliable impression. He definitely would not talk nonsense.
Most of the customers believed Lu Qin.
"Boss Lu, tell us about it. Give us some science—how exactly did you tell that something had been added to this food?"
Everyone grew curious and began asking.
Lu Qin packed up the three portions of fried noodles and handed them to the customers. Then he temporarily turned off the heat and spent two minutes explaining it to everyone.
"I knew something had been added without even tasting it. First, I looked at the color. Second, I smelled it."
"For example, this fried rice noodles..."
Lu Qin brought over Liu's portion of fried rice noodles and stirred it around with his chopsticks.
"The color is a little darker than normal fried rice noodles. That isn't because soy sauce or other seasonings were added. It's because Rongalite was added to the rice noodles themselves."
"Rice noodles with Rongalite added will turn especially dark after being stir-fried over high heat."
"Rongalite?"
"What's that?"
Some customers did not understand. They had never even heard of it.
Lu Qin said, "Rongalite is a chemical additive. When added to flour, it can not only whiten it, but also increase its elasticity and preserve it."
"If a merchant is unscrupulous and chasing profits, they'll buy rice noodles or rice that have had Rongalite added. From now on, everyone needs to watch out when eating fried rice noodles or stir-fried noodles."
Lu Qin spoke seriously.
