Meh, they're really not that much different unless the flour is "100% whole wheat."
Whole wheat flour is just that, wheat that is ground into flour with nothing removed. White flour is just the middle part of the wheat kernel without the bran or wheat germ. Enriched flour has vitamins added to it to make up for the bran and wheat germ. Refined could mean any of these other than whole wheat.
No matter how much fiber it has it is unhealthy if it has enriched bleached wheat flour, which is almost the same as white flour.
No they are made with enriched wheat flour.
The chemical formula for enriched egg noodles is not typically provided, as enriched egg noodles are a food product made from wheat flour, eggs, and sometimes additional nutrients like iron and B vitamins added during processing. The main components are carbohydrates from wheat flour and protein from eggs.
Most things you can replace 1/3 to 1/2 of regular flour with whole wheat flour. The end product will be heavier and some things may tend to fall apart easier. Some things have to have only regular flour.
There is no yeast at all in enriched flour. Enriched flour has a few specific nutrients added to replace some of the nutrients lost when the bran and germ are removed from whole wheat to produce white flour. Yeast must be added to enriched flour if it is used to make bread. See the Wikipedia article linked below for additional information.
No, gluten free pasta is made of corn flour and/or rice flour neither of which contain gluten instead of the durum wheat flour and?or semolina wheat flour both of which contain gluten (present in all wheat based products).
Yes, it contains wheat flour. Any product having "flour, enriched flour, ect..) on the label is not gluten free.
Most people use an all-purpose white flour made from wheat, but I've seen recipes that called for whole wheat, rice, or buckwheat flours as well
if they're protein free then you're safe but check the ingredients for wheat flour, enriched flour and protein isolates.
Flour oftentimes goes through a process known as bleaching. This makes the white baking flour most people are accustomed to and which they like to use in baking; however, while this makes the flour more suitable to common baked goods, it also strips much of the nutritional value from the flour. Vitamins are sometimes added to this flour making it 'enriched' white flour. By not doing the bleaching process, you retain the whole wheat aspect of the flour, making it healthier and heartier, and don't necessarily need to 'enrich' the flour.
