1. What is Dry Matter Protein?

Dry Matter Protein (DMP) is the protein content of a food or feed after removing all moisture. It provides a more accurate comparison of protein content between products with different moisture levels.

2. How Does the Calculator Work?

The calculator uses the Dry Matter Protein formula:

Where:

• \( Protein \) — Protein content as percentage of wet weight
• \( Moisture \) — Moisture content as percentage of wet weight

Explanation: The formula adjusts the protein percentage by removing the moisture component to show the true protein concentration in the dry matter.

3. Importance of Dry Matter Protein

Details: DMP is essential for comparing nutritional value of different feeds or foods, especially when they have varying moisture contents. It's widely used in animal nutrition and food science.

4. Using the Calculator

Tips: Enter protein and moisture percentages (both as wet weight basis). Values must be between 0-100%, and moisture must be less than 100%.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate dry matter protein?
A: It allows fair comparison between products with different moisture levels by showing the protein content on a moisture-free basis.

Q2: What's a typical dry matter protein range?
A: Varies by product. For animal feeds, 10-40% DMP is common. Human foods range widely from 5% (grains) to 90% (protein isolates).

Q3: How is moisture content determined?
A: Typically measured by drying a sample to constant weight in an oven and calculating weight loss.

Q4: Can moisture be more than 100%?
A: No, moisture percentage is always less than 100% of the total weight.

Q5: Is this calculation used for all food types?
A: Yes, it's applicable to any food or feed where you need to compare protein content independent of moisture differences.
