Information from a doctor;
"Our family stopped consumed instant noodles from about 5 years ago since we have known about candle that apparently coated the instant noodles. This candle not only coated the sterofoam but also the instant noodles! That`s why instant noodles don`t stick with each other when being cooked."
If we noticed enough yellow chinese noodles that we usually find in the market, from what we saw is, before being cooked, the noodles would appear to be oily. The oil layer will prevent sticky noodles. We usually spread flour onto Raw Wonton noodles so that the noodles won`t get sticky each other.
