Is parboiled long grain rice vegan?

Parboiled long grain rice is a cultivated cereal grain harvested from the rice plant that has undergone a specialized hydrothermal treatment prior to milling. It originates from agricultural crops and is processed by soaking the rough, unhulled rice grains in water, steaming them under pressure, and drying them before the outer husk and bran layers are mechanically removed. This industrial process gelatinizes the internal starch and alters the texture of the grain, resulting in cooked rice that remains firm and separate.

This ingredient is commonly found in packaged dry rice pouches, boxed seasoned rice mixes, canned soups, frozen prepared meals, and shelf-stable ready-to-heat side dishes. Parboiled long grain rice is classified as vegan because it is derived entirely from a plant source. The standard parboiling and milling methods rely solely on heat, water, and mechanical machinery, with no animal derivatives, animal fats, or animal-based processing aids used at any stage of production.
