Moisture

Moisture refers to the presence of a liquid, especially water, often in trace amounts. Small amounts of water may be found, for example, in the air (Atmosphere), in foods, and in various commercial products. Control of moisture in products can be a vital part of the process of the product. There is a substantial amount of moisture in what seems to be dry matter. Ranging in products from cornflake cereals to washing powders, moisture can play an important role in the final quality of the product. There are two main aspects of concern in moisture control in products: allowing too much moisture or too little of it. For example, water moisture in steel furnaces play a major role in the quality of the steel.

Moisture in the Atmosphere

Atmosphere contains moisture in the form of water vapor. The amount of moisture present in the atmosphere is referred to as Humidity. High levels of humidity can cause discomfort and can also lead to excessive sweating, dehydration, and heat stroke. On the other hand, low levels of humidity can cause dry skin and respiratory discomfort.

Moisture in Food

Moisture is a critical factor in food quality, preservation, and resistance to deterioration. Determining the moisture levels in foods also plays an important role in ensuring consumer safety, as high levels of moisture can lead to the growth of mold or bacteria.

Moisture in Commercial Products

Many commercial products have to have their moisture levels tested and controlled to ensure their quality and longevity. For example, high levels of moisture in a product like cornflakes can lead to spoilage and decreased crunchiness.

Moisture Control

Moisture control in products can be achieved through a variety of methods. These include the use of desiccants, air conditioning, dehumidifiers, and other moisture-absorbing substances.
