enriched wheat flour

I am allergic to barley. While reading ingredients I’ve noticed that a lot of enriched wheat flour does have barley flour too. If it isn’t listed in the ingredients, does it mean there is no barley flour? Sometimes it has vitamins, etc. listed with barley flour and other times it’s not listed. What exactly does enriched wheat flour mean?

this is copied from the website dietician.com hope it helps:

The ingredient listing on food labels contains the raw ingredients in decreasing order used in the manufacture of that particular food. Typically the type of flour describes the milling process (how the grain was ground into a flour) i.e. was the bran (outer coating) and / or the germ (oil portion) included AND any treatment applied after milling i.e. enrichment (add vitamins and minerals lost during processing) or bleaching (natural aging of flour during storage or achieved with chemicals that oxidize the yellow pigment and improve the baking quality of the flour).

The following wheat flours do not include red durum or semolina, which contains bran specs from durum and both are used in the manufacture of pasta. Nor are soft wheat flours included, which are used in the manufacture of cakes, cookies and pastries. Bread flours are made from hard wheat, which contains more gluten (protein) and provides structure to bread.

Wheat Flour is made by grinding wheat and typically does not contain the bran or germ.

Enriched Flour (wheat) is wheat flour (no bran or germ) that has been enriched with thiamin, riboflavin and niacin and may include Vitamin D, iron and calcium that are lost during flour processing.

Enriched Flour (flour) is the same as the above except that the source of the grain is not identified. Other grains such as rye, oats, barley or soybeans can be used in the making of this flour.

Stone Ground Wheat Flour describes how the wheat grain was milled. Again since the word “whole” is not included and this flour does not contain the bran or germ of the wheat grain. Similar to wheat flour other than how the grain was milled.

Grinding the entire wheat grain makes whole Wheat Flour, including the bran and germ. Other ingredients may be included such as malted wheat, wheat flour and barley flour. It is also called graham flour and entire wheat flour.

Cracked Wheat is made by cracking the wheat grain into angular pieces and is similar to whole-wheat flour in composition, but the flour has coarse flecks of brown rather than a uniform size partic
