Hydrogen Peroxide 3% vs 35%: Which One Should You Buy?
Why Serious Home Bakers Are Switching to Organic Yeast (And What's Actually in the Conventional Stuff)
There's a quiet revolution happening in home kitchens across Australia. More people are baking their own bread - sourdough, pizza, focaccia, brioche - and they're paying closer attention to what goes into their dough. Flour, water, salt, yeast. Simple, right?
Mostly. But if you've ever flipped over a standard packet of instant dry yeast and looked at the ingredients list, you might have noticed something unexpected: E491.
What Is E491, and Why Is It in Your Yeast?
E491 is sorbitan monostearate, a synthetic emulsifier made by chemically combining sorbitol and stearic acid. It's added to instant dry yeast because it protects the yeast cells during the drying process and helps them rehydrate more quickly when they hit liquid. BakeryBits From a purely functional standpoint, it does its job.
But for home bakers who are trying to keep their pantry as clean and additive-free as possible, it's an unwanted extra. And for people with sensitivities to certain emulsifiers or synthetic food additives, it can be genuinely problematic.
This is where organic yeast - specifically Bioreal - comes in.
What Makes Bioreal Different?
Bioreal is made without synthetic chemicals, using certified organic ingredients and in a fully ecologically sound production process. Healthnutsaustralia The yeast is instant - meaning it can be added directly to flour without any pre-dissolving - but it achieves this without the emulsifier shortcut.
The single ingredient is yeast (Saccharomyces cerevisiae), naturally fermented from rye grain. That's it.
No E491. No ascorbic acid. No additives of any kind.
For bakers who already choose organic flour, organic oil, and free-range eggs, using conventional yeast has always been a small contradiction. Bioreal closes that gap.
Does It Perform as Well?
This is the question most people ask first, and the answer is: yes, with one small note.
Because it contains no emulsifier, you may need to use slightly more than you would with a conventional emulsifier-containing yeast. eBay Most bakers find 9g per 500g of flour works well. The proof time may be a touch longer, but the result - a light, well-risen crumb with clean flavour - is worth it.
The individual sachets matter here too. Each 9g portion is sealed separately, so you're always working with fresh, active yeast. No half-open packets going stale in the back of the pantry.
Organic vs Conventional Yeast: The Key Differences
The yeast organism itself - Saccharomyces cerevisiae - is the same in both organic and conventional versions. What differs is the production process and what gets added along the way.
Conventional instant yeast is grown on non-organic substrates and has emulsifiers added to improve shelf stability and rehydration speed. Organic yeast must be grown on certified organic feedstocks, cannot contain synthetic additives, and is produced under regulated ecological standards. The result is a cleaner ingredient list and a product that fits genuinely into an organic kitchen.
What Can You Make With It?
Bioreal works for any recipe that calls for dry or instant yeast. At Santos, we think it's especially good for:
Everyday bread - the kind you make on a Sunday and slice through the week. The slower, cleaner fermentation gives the loaf a more developed flavour than fast-acting commercial yeasts.
Pizza bases - try a 48–72 hour cold ferment in the fridge. The extended time allows the yeast to develop complex flavour compounds and creates a lighter, more digestible crust.
Focaccia - generous olive oil, good sea salt, and a yeast that doesn't bring any synthetic passengers.
Enriched doughs - brioche, cinnamon scrolls, hot cross buns. Bioreal handles these beautifully.
A Note on Storage
Yeast is a living organism and hates heat and moisture. Keep Bioreal in a cool, dry place and during Australia's warmer months, move it to the fridge. The individual sachet format means you're only ever opening what you need.
Where to Find It
We stock Bioreal Organic Dry Yeast in our Byron Bay and Mullumbimby stores, and online for delivery Australia-wide. Each pack contains five 9g sachets - enough for five separate bakes, or roughly five loaves of bread.
If you're already buying organic flour and caring about what goes into your food, it makes sense to apply the same thinking to your yeast.
