What is CRUDE FIBER DETERMINATION?
In layman's terms, analysis of crude fiber in the laboratory involves oven-drying the fiber to be analyzed after exposing it to a series of sulfuric acid and sodium hydroxide solutions. What's left is crude fiber: a mixture of insoluble fibers that have no nutritional value.
