Factors to Consider When Choosing a Desiccant


Over the last few years, the way food is consumed and packaged in India has transformed. According to The Economic Times, awareness surrounding food safety has risen majorly, pushing businesses to employ healthier and safer options.

Over the past few years, even the Food Safety and Standards Authority of India (FSSAI) has taken the initiative to create a healthy regulatory environment for food companies.

Silica gel and oxygen absorbers play a key role here. Let’s see what they do:

What You Need to Know About Water Contamination

Desiccants are designed to eliminate water and moisture contamination, of which there are four sources, in closed packages or containers. These sources include:

  • Water vapor contained in the air inside the container
  • The moisture contained by the material inside the container
  • Moisture on the interior surfaces of the package
  • Moisture that has entered the package due to leakage or permeation

The right type of desiccant for a product is determined by the nature of the product itself, the type of the container, and the climate of the environments the container will be exposed to. Different desiccants have varying properties, which make them suitable for specific types of products and environments.

For instance, silica is a cost-effective, FDA-approved food and drug desiccant that has superb moisture absorption capabilities. However, it doesn’t perform well in environments with low H20 concentrations and in extreme heat. Molecular sieves, on the other hand, have slightly inferior absorption capabilities, but can remain effective even in extremely high temperatures.

Here’s a breakdown of the key factors you need to consider when choosing an industrial desiccant.

Know the Product

The first thig you need to take into consideration is the nature of the product it highly sensitive to moisture and humidity, or does it have good tolerance? In other words, how dry does the product need to stay to maintain its efficacy? Is the product a liquid or a solid?

Know the Environment

The second factor you need to consider is the type of weather conditions the product will be exposed to. Weather can have significant influence on the levels of humidity inside the container, and as we’ve mentioned above, the effectiveness of a desiccant can vary with changes in temperature.

Know the Packaging

Last but not the least, you need to consider the type of packaging you’re using for your product. This could be a cardboard box, a plastic bag, Tupperware, – the list can go on and on. Each packaging material has its own characteristics, and key perimeters, such as seal type, permeability, and corrosion resistance can vary from one material to another.
