Protein in Rajma per 100g: Complete Breakdown

Understanding the protein in rajma per 100g requires examining both raw and cooked forms.

Why Does Protein Content Change After Cooking?

Rajma does not lose protein when cooked. Instead:

• It absorbs water during soaking and boiling

• Its weight increases significantly

• Protein gets distributed over a larger volume

As a result, the protein content per 100g appears lower, but the total protein remains unchanged.

For example, 100g of raw rajma expands to approximately 250–300g after cooking, while still retaining the same total protein content.

Protein Quality in Rajma

The protein in rajma per 100g is plant-based and contains several essential amino acids, but it is not a complete protein on its own.

Amino Acid Profile

Rajma is:

• High in lysine

Because of this, it lacks one of the essential amino acids required for complete protein synthesis.

How to Make It Complete

Combining rajma with grains such as:

• Rice

• Wheat (roti)

• Millets

helps create a complete amino acid profile. This traditional combination enhances the biological value of the protein.
