Enzymatic-gravimetric methods. In the early 1980s, a enzymatic-gravimetric method was developed in which the sum of soluble and insoluble polysaccharides and lignin were measured as a unit and considered to be total dietary fibre (TDF). That method is detailed in section 45.4.07 of the AOAC International Official Methods of Analysis (45). An integrated total dietary fibre method was evaluated and accepted by AOAC International and AACC International (AOAC Methods 2009.01 and 2011.25; AACC Method 32–45.01 and 32–50.01, and recently adopted by Codex Alimentarius as a Type I Method. However, in application of the method to a diverse range of food samples and particularly food .
Two methods (an AOAC and a simplified enzymatic-gravimetric method) were used to analyze seven types of canned legumes and eight cooked legumes. Total dietary fiber (TDF) of the canned products ranged between 17% and 23% (dry basis) for chick peas, The analysis of total dietary fiber was carried out with the Total Dietary Fiber Assay Kit (Sigma-Aldrich, Steinheim, Germany) based on a combination of enzymatic and gravimetric methods.A recently proposed bile-enzymatic-gravimetric total dietary fiber (TDF) method was modified and the new procedure was compared with the original method, the traditional AOAC enzymatic-gravimetric determination (AOAC Official Method 985.29), and another simplified AOAC procedure by analyzing several diet composites, including National Institute of Standards and .Based on these studies simplified methods for the preparation of dietary fibre (DF) have been formulated. .

Gravimetric analysis is a quantitative method used in analytical chemistry to determine the amount of a substance present in a sample by measuring its mass. This technique relies on the principles of precipitation and weighing to isolate and quantify the analyte of interest. This method is often used in environmental monitoring, pharmaceutical .Simplified Enzymatic-gravimetric Method for Total Dietary Fiber In Legumes Compared with a Modified AOAC Method. MARIA TORRES CARDOZO. 1993, Journal of Food Science.Enzymatic gravimetric methods date back to the 19th century. In the 1930s, McCance et al. measured total unavailable carbohydrates in fruits, nuts, and vegetables by determining the residue insoluble in 80% ethanol. This was corrected for starch measured after enzymatic hydrolysis with taka-diastase and for protein.
