Standard -AOAC985.29 dietary fiber measurement: GB
Enzyme is a gravimetric method developed in the 1980s, has become AOAC approved methods. It is a natural chemical reaction simulation of dietary fiber in the human digestive tract were detected. This method can be analyzed for total dietary fiber foods (TDF), soluble dietary fiber (SDF) and insoluble dietary fiber (IDF). Its principle is separately analyzed using thermostable a- amylase, protease, glucosidase was digested samples were digested with acetyl aceton and drunk, dried, and weighed. IDF IDF and SDF are instantly filtered after sample digestion, and the residue filtered rinse with hot water, after drying weighed. SDF is above filtrate was precipitated with ethanol, the residue was dry, and weighed. Finally TDF, IDF and SDF be corrected by protein content and ash content. AOAC985.29 official is the most common method for determining dietary fiber content, in 2007 the Ministry of Health requested "food nutrition labeling standard," also this standard as a reference standard.
