Answer 1

The magical word is “prepared” that meant for the soup when you mix water and noodles and the rest of the stuff in the packet.

The values for rice noodles are for the product as it is in the packet.

If the energy is the same when dried and it contains 85g of dried noodles the weight of a serving is 347*85/76=388g. So you need to add 300g =3 dl (1 and a quarter cup) of water.

So if the packet s 85g and say to add 3 dl of water the energy density is identical in the two products.

My instant noodle has a listing of 410kcal for the packet so 482kcal per 100 grams and my rice noodles are at 375kcal per 100g. So instant noodles have higher energy density because they contain more fat 21g/100g vs 1.2g/100g.
