wheaten points (a 19th century or earlier term), what is it?

I’m working on a short documentary film on a history topic and use the following text taken from the Russian catalog of World’s Columbian Exposition (1893, Chicago) in English:

… presented products from a steam flour mill: flour of various sorts, middlings, coarse and fine flour, flour dust and bran, cleaned
and uncleaned Spring and Winter wheat and Wheaten points. The firm
was founded in 1837.

The text in Russian is unavalable. The catalog in Russian can only be purchased (history document).
I don’t know what are "wheaten points". I can’t even imagine what it could be, considering the description concerns Russian products. My only guess is ribbons or cords used in dresses as fastening parts (of 16-17th century), they were called points. But it doesn’t fit into the context, and I don’t think they, the points, could be made of wheat. Maybe there is a typo or a mistake, I don’t know. Google search doesn’t help. Hope someone helps me.
