Unveiling the science behind longer-lasting fizz

Posted in Industry News


When it comes to enjoying a carbonated beverage, there’s something undeniably satisfying about that effervescent fizz dancing on your tongue. However, maintaining that fizziness over time has long been a challenge for beverage manufacturers. Enter CO2Sustain, a groundbreaking innovation that’s changing the game in the world of carbonation. In this blog, we’ll delve into the science behind CO2Sustain and uncover how it works its magic to keep your drinks fizzier for longer.

The basics of carbonation:

Before we explore CO2Sustain, let’s take a moment to understand the basics of carbonation. Carbonated beverages, such as sodas and sparkling waters, get their bubbles from dissolved carbon dioxide (CO2) gas. When you crack open a can or bottle, the sudden release of pressure allows the CO2 to escape from the liquid, creating those delightful bubbles.

The challenge of fizz maintenance:

While carbonation adds that refreshing tingle to our drinks, it’s notoriously ephemeral. Over time, the CO2 gas naturally escapes from the liquid, leading to a loss of fizziness and a flat-tasting beverage. This poses a significant challenge for beverage manufacturers striving to deliver consistently high-quality products to consumers.

Enter CO2Sustain:

Our solution is  cutting-edge, designed to address the issue of carbonation loss in beverages. At its core, CO2Sustain is a patented liquid additive that helps to maintain carbonation levels in drinks over an extended period. But how does it accomplish this feat?

The science behind it

CO2Sustain works by forming a protective barrier around the CO2 bubbles in the beverage, effectively keeping the smaller and stronger. This barrier is created through a combination of surface-active agents, which interact with the CO2 molecules to enhance their stability. The smaller bubbles bounce off each other and remain smaller in the drink, retaining carbonation and fizz. Without CO2Sustain bubbles merge to create bigger CO2 bubbles which quickly rise meaning carbonation is lost and drinks rapidly go flat. The sensation of extra tingle and bite in the drink is also improved.

The benefits:

The benefits extend beyond simply prolonging the fizziness and sensory experience of carbonated beverages.

By maintaining carbonation levels, CO2Sustain helps to preserve the sensory experience that consumers love, ensuring that each sip is as satisfying as the first. Additionally, by reducing the rate of carbonation loss, CO2Sustain can enhance the shelf life of beverages, minimizing product waste and improving cost-effectiveness for manufacturers.

In the world of carbonation, maintaining the perfect level of fizziness is both an art and a science. With CO2Sustain, beverage manufacturers have a powerful tool at their disposal to ensure that their products retain their effervescence for longer periods, delighting consumers with every sip.
