About Us – Siemer Specialty Ingredients


About Us

Put natural goodness behind your good name.

Today’s consumers are looking to take home food with cleaner labels and more natural ingredients. Siemer’s naturally treated wheat flour, germ and bran enable food manufacturers like you to replace chemically modified ingredients in foods and mixes – offering satisfaction for the consumer and improved product performance for you.

Our specialty line of all natural Heat Treated (HT) flours replace chemically modified starches, providing critical attributes needed for thermally processed foods as well as dry mixes. Our stabilized germ can replace chemically defatted wheat germ and a new natural process perfectly mimics chlorinated cake flour. And because food safety is paramount, we provide flour treated for applications that are potentially eaten prior to applying a kill step – such as cookie dough, ice cream inclusions or seasoning blends – to reduce risk to your customers and your reputation.

It’s only natural.

As a division of  Siemer Milling Company, we’ve been working with flour, food ingredients and exceptional customers since 1882, helping to make products more functional, more marketable and more cost-effective to produce – without loss of any nutritional aspects.

The reason we’re still here in the 21st century is because we strengthen our products and relationships through continuous research, development and commitment to excellence. Our team of R&D professionals works together in our labs and our test kitchen to improve the quality of our products and ensure the functionality our customers ask for.


Through personal professionalism, we deliver best-value food products to improve the quality of life.
