[Read more] Trying to pick the perfect moisture balance out of the many options? It can be daunting to choose the best moisture analyzer.
A moisture analyzer determines the moisture content of a sample. There are several types of moisture content (Mc) instruments.
Moisture sorption isotherms are a powerful tool for predicting and extending the shelf life of a product, displaying changes in water activity over time.
Learn how water activity is used to control food safety, prevent spoilage, and meet regulatory requirements. Essential reading for food quality professionals.
Water activity is defined as the ratio of the vapor pressure of water in a material (p) to the vapor pressure of pure water (po) at the same temperature.
Does a food product's water activity level change when frozen? What about thawed? After a month of research and testing, here's what our scientists said.
With water activity’s greater popularity in pharmaceutical has come new regulations and standards.
When measuring the water activity (also known as aw, RH, ERH, or vapor pressure) of a product, certain ingredients – volatile compounds – can cause problems. Some water activity sensors are better protected against volatiles than others. So how much protection do you need?
Less processing plus longer-term preservation – hurdle technology offers big benefits. But which of the 50+ hurdles is right for you?
Candy, confectionery, chips and snacks – without the right texture, food loses its appeal. Aw helps you nail the perfect texture.
Shelf life testing can be overwhelming, time-consuming, and expensive. Water activity measurements offer a far easier and more affordable way. Here's why.
Most companies log data. Only the best use it to their competitive advantage. The right tools can transform data into a profitable course of action.
You only need two key metrics to evaluate packaging: water activity and package permeability. Let's explore how to use them and why they're important.
Moisture content and water activity have to do with water, but the distinction isn’t always clear. Learn why to measure moisture content and water activity.
Moisture content affects texture, shelf life, and safety. Learn the difference between moisture content and water activity, and how to measure both accurately.
Fruits and nuts appeal to consumers, who love seeing familiar foods on ingredient lists. But working with natural products can be tricky.
Discover the critical water activity thresholds that limit bacteria, mold, and yeast growth — and how to use them to protect food safety and shelf life.
[Science delivered] Water activity and pH are two measurements that are better together. Use commercial instruments to simplify your workflow.
Water activity, not water content, predicts how water will migrate. Knowing your water activity levels helps you determine how to formulate and package.
Most food companies know they could optimize their drying processes to some degree. But almost all of them underestimate what they’d gain by doing so – and what they lose by ignoring problems.
What if there was a way to control how quickly your products went rancid and bitter? Turns out there is – water activity is the answer.
Regulatory bodies around the globe require the use of water activity. We've compiled a complete regulation reference list.
Most people intuitively know what a powder is. They’re everywhere. We interact with them daily. But with so many different categories of powder – spices, ingredients, cosmetics, pharmaceutical excipients and APIs, and countless others – it can be tough to define and resolve specific issues.
The water in food and pharma products impacts how they’re used, when they degrade, and more. Moisture can’t be safely ignored – so how can its impact be measured and accounted for?
A change in energy comes with a change in vapor pressure. Let's break down how the first law of thermodynamics can help calculate the amount of change.
Stop guessing at shelf life. Learn how water activity measures water behavior to prevent mold, clumping, and spoilage in your products.
