What is moisture content of food?

Moisture content is the quantity of water contained in a food material. Moisture content is expressed as a percentage of moisture based on total weight (wet basis) or dry matter (dry basis). Wet basis moisture content is generally used. Dry basis is used primarily in research.

What is meant by moisture content?

Moisture content (MC) is a reference to the amount of moisture present in a material. This value is often represented as a percentage of the material’s mass (such as X% MC). The amount of moisture in an object can be measured in several different ways, such as with oven-dry tests or moisture meters.

How do you measure moisture content in food?

Here are some of the methods for determining the moisture content of foods and beverages:

1. Oven Drying. This is the standard against which other methods are compared.
2. Microwaves.
3. Karl Fisher Titration/Homogenization.
4. Near-Infrared Spectrometry.
5. Freezing-Point Depression/Cryoscopy.

What is the function of moisture content?

Moisture content of the food material is important to consider the food is suitable before the consumption, because moisture content affects the physical, chemical aspects of food which relates with the freshness and stability for the storage of the food for a long period of time and the moisture content determine the …

What’s the relationship between water and moisture in food?

The relationship between total moisture and water activity is complex, is related to the relative humidity of the food and its water content and must be determined for each specific food. Foods with higher moisture content might be expected to have higher water activity than dry foods but the expectation is not necessarily correct.

What does higher moisture content in dog food mean?

However, a food that has a higher or lower moisture content doesn’t necessarily mean that it’s better or worse. Rather, it means that certain types of dog food will benefit different types of dogs depending on the state of their health, age, or calorie intake requirements.

How is the total water content of food determined?

The total water content of food involves the concepts of “free” and “bound” water, equilibrium moisture content, moisture adsorption, moisture desorption etc. The most important term is “bound” water on which the ultimate accuracy of a method for moisture content determination is related.

What foods have higher moisture content than dry foods?

Foods with higher moisture content might be expected to have higher water activity than dry foods but the expectation is not necessarily correct. Products with the same water content may have very different water activities. For example, salami and cooked beef have similar total moisture (approximately 60%).
