When did humans first make cereal flour?

Archaeologists have found evidence of humans making cereal flour over 14,000 years ago. This discovery comes from Shubayqa 1, a Natufian hunter-gatherer site located in northwest Jordan.

What happened to flour shelf life during industrialization?

Fatty acids within the germ reacted when exposed to oxygen after milling and caused flour to become rancid within six to nine months depending on climate. Degermed flour became standard because removing the germ extended shelf life significantly.

Which countries require wheat flour fortification as of 2016?
