Hi,

 

You could use a lab to test it. Alternatively, there's McCance & Widdowson, the reference for calculations, or you could look at software such as Nutricalc.

Thank you very much for reply Jim.

 

I know methods for Protein and Fat but not for carbohydrate analysis by lab test.

 

No information on how to calculate energy from all these 3 parameters.

 

If you can provide these detials, then it will best.

 

Thanks

 

Bhavin

If you're planning to do this yourself, then I can't help you. I have always relied on external lab testing (Eurofins, SGS  and others will do this in India). I have also used Nutricalc and found it very useful.

 

The key challenges are having a representative sample and accepting the wide tolerances of a non-homogeneous product.

    Dear Bhavin

 

                If your products are made from natural ingredents than go for calculation method. natural products have different value as per maturity &season

Hi Bhavin.

 

Not sure if you found an answer to your query?

 

Most labs will calculated carbohydrate by difference, rather than as an analyte in it's own right. (although starch and sugars can be tested independently). The methods you need are ash, moisture, fat and protein. (And dietary fibre if you want to calculate available carbohydrate)

 

% Total Carbohydrate = 100 - (% Ash + % Moisture + % Fat + % Protein)

% Available Carbohydrate = 100 - (% Ash + % Moisture + % Fat + % Protein + Dietary Fibre)

 

Hope this helps
