Biochemistry Calculators

Crude Fibre

This calculator estimates the crude fibre content in feed or food samples using the standard gravimetric method. It is especially useful for chemists, food scientists, and agriculture professionals to determine the indigestible fibrous residue after acid and alkaline digestion. Just enter the weights before and after ashing, along with the sample weight, to get the crude fibre percentage.

Crude Protein

This Crude Protein Calculator helps determine the total protein content in a sample using the micro Kjeldahl distillation method. It is widely used in food, feed, and agricultural industries to estimate the nitrogen content, including from both protein and non-protein sources, and convert it into crude protein. Simply input the blank and actual titre values, NaOH normality, and sample weight to get accurate protein percentage results.
