Carbohydrates values determined by the general approach described above, are defined as:

Title of page

Another way to determine available carbohydrates is by direct analysis. In this approach all individual carbohydrates are determined analytically and added up to obtain a available carbohydrate value. Generally this approach consists of 4 steps:

Note this is a very general approach. Several variations based on this approach are possible. The next pages first focus on the subsequent steps of this general approach. Than, some attention is given to the variations in this general approach.

unavailable carbohydrates

available carbohydrates

total carbohydrates (thus available and unavailable together).

Not right. Unavailable carbohydrates are those that resist digestion in the small intestine. Extraction and hydrolysis of sugars and starch mimics more or less intestinal digestion. So unavailable carbohydrates (like cellulose and pectin) will not be extracted and hydrolyzed in this approach. Therefore this approach does not determine unavailable carbohydrates.

Right. Available carbohydrates are those digested in the small intestine and metabolized as carbohydrates by the human body. Extraction and hydrolysis of sugars and starch mimics more or less intestinal digestion. So unavailable carbohydrates (like cellulose and pectin) will not be extracted and hydrolyzed in this approach. Therefore this approach does not determine unavailable carbohydrates but only available carbohydrates.
