Nitro-Milled White Chia Flour - Chia Seed Flour - Onset Worldwide: White chia flour is a light tan color, has a mild nutty flavor, and is high in healthy omega-3 fatty acids. White chia flour, along with all flours in our nitro-milled flour line, are gluten free, grain, free and great substitutes for traditional flour. Starting out as an importer of chia seeds, Onset Worldwide quickly became one of the East Coast’s largest importers and suppliers to manufacturers, bakeries, retail brands, and more. Our propriety processing lines were developed by Onset Worldwide to clean, mill, pack, and private-label seeds, grains, and flours into bulk and food service packaging.
