Cold Fermented vs Pasteurised Drinks – Why It Matters for Probiotics

Cold Fermented vs Pasteurised Drinks – Why It Matters for Probiotics

Introduction

If you have been shopping for probiotic drinks in the UAE, you have probably noticed that most products on supermarket shelves do not require refrigeration. This should be a red flag. Genuine probiotic drinks - those with live, active cultures - must be kept cold. Room-temperature 'probiotic' drinks have almost certainly been pasteurised, which kills the bacteria that give these products their value. Understanding the difference between cold-fermented and pasteurised drinks is essential knowledge for anyone serious about gut health.

The Fermentation Process

Cold fermentation is the traditional method of producing fermented beverages and foods. Microorganisms - typically lactic acid bacteria - are introduced to a food substrate (in FERMA's case, beetroot and carrot juice) and allowed to ferment at low temperatures over an extended period. This produces a rich ecosystem of live bacteria, beneficial enzymes, and fermentation by-products without ever applying heat that would compromise the live cultures. Pasteurisation, by contrast, involves heating the finished product to 72°C or higher for a period sufficient to kill all microorganisms - beneficial and harmful alike - to extend shelf life.

The Probiotic Death Temperature: What Pasteurisation Does

Most probiotic bacteria - lactobacillus and Bifidobacterium strains - cannot survive temperatures above 40 to 46°C. Pasteurisation at 72°C kills 99.9% of all live cultures in a beverage. This is intentional from a food safety and shelf life perspective, but it completely defeats the purpose of consuming a probiotic drink. A pasteurised 'probiotic drink' delivers dead bacteria - which provide no measurable gut health benefit. FERMA avoids this entirely. Every bottle is cold-fermented, bottled fresh, and kept refrigerated throughout the supply chain to ensure you receive every live culture that was created during fermentation.

Why FERMA Does It Better

Small-batch cold fermentation: FERMA ferments in small batches at controlled low temperatures - never with added heat. This preserves more live cultures and a broader spectrum of fermentation-derived compounds than large-scale industrial fermentation.

No pasteurisation: Many commercial fermented drinks are pasteurised after production, killing the very bacteria that make them valuable. FERMA skips this step entirely, delivering every live culture to you intact.

Real ingredients only: No concentrates, no flavour extracts, no additives. The ingredients list is exactly what you see: fermented beetroot, fermented carrot, live cultures.

Frequently Asked Questions

How can I tell if a probiotic drink is pasteurised?

The easiest test: does it require refrigeration? Genuine live-culture probiotic drinks require refrigeration because live bacteria are sensitive to heat. Room-temperature probiotic drinks have been pasteurised and contain no live cultures.

Is cold-fermented safer than pasteurised?

Yes - cold fermentation produces an acidic (low pH) environment due to lactic acid production. This acidity naturally inhibits the growth of harmful pathogens, making cold-fermented products like FERMA both safe and rich in live cultures.

Does FERMA have a shorter shelf life because it's not pasteurised?

Yes - FERMA has a shorter shelf life than pasteurised alternatives, which is a direct indicator of its freshness and live culture potency. FERMA is made fresh and should be consumed within the refrigerated use-by period.

Why do most brands pasteurise their probiotic drinks?

Pasteurisation extends shelf life dramatically, reducing waste and enabling nationwide distribution without refrigeration. It is a commercial decision, not a health decision — and one that FERMA refuses to make.
