Fiber Analyzer is appropriate for the content analysis of the Crude Fiber, acid/alkaline detergent fiber (ADF), neutral detergent fiber (NDF), acid detergent lignin (ADL), cellulose and hemicellulose in the raw materials and finished products of food, grain and feed.
Under the function of diluted sulphuric acid, the sugar, starch, pectic substance and hemicellulose in the sample are eliminated through hydrolyzation, then protein and fatty acid are eliminated through alkali treatment. Then mineral substance is eliminated through high temperature firing and the remaining substance is crude fiber.
