If you’ve ever read a food label and spotted Starch Sodium Octenyl Succinate (E1450), you might have wondered what it actually is – and whether it’s safe. The truth is, this modified starch plays a quiet but vital role in making many of our favourite foods smoother, creamier, and longer-lasting.
From emulsifying dressings to giving ice cream that perfect texture, E1450 is a behind-the-scenes hero in modern food production. But how is it made? Why do manufacturers use it? And what’s the verdict from global food safety authorities?
In this guide, we’re going to unpack exactly what E1450 is, how it works in your food, and what you need to know about its safety, benefits, and everyday uses. Let’s get started.
What is Starch Sodium Octenyl Succinate E1450
Starch Sodium Octenyl Succinate, commonly known by its food additive code E1450, is a type of modified starch widely used in the food industry. It is created by chemically modifying a natural starch – often from maize, tapioca or potato – with octenyl succinic anhydride (OSA). This modification enhances the starch’s functional properties, particularly its ability to emulsify and stabilise mixtures.
From a chemical standpoint, E1450 is a starch molecule whose hydroxyl groups have been partially substituted with octenyl succinate groups, and neutralised with sodium. This alteration changes the way the starch behaves in water and oil systems, giving it better dispersibility, film-forming capacity, and improved resistance to heat, acid, and shear during processing.
The E number classification system, used across the UK, EU, and many other regions, identifies approved food additives for safety and regulatory purposes. In this system, E1450 specifically denotes starch sodium octenyl succinate, grouping it within starch-based thickeners, stabilisers, and emulsifiers. Being an approved additive means it has undergone safety assessments by recognised authorities before being permitted for use in food and drink products.
Functional properties of E1450
E1450, or starch sodium octenyl succinate, is valued in the food industry for its ability to stabilise, emulsify, and thicken a wide range of products. It works by helping oil and water mix smoothly, preventing separation, and keeping textures uniform throughout a product’s shelf life.
In foods like sauces, dressings, dairy desserts, and plant-based drinks, E1450 improves body and mouthfeel without making the texture heavy or gluey. It also helps stop ingredients from settling at the bottom or forming lumps, which means a more appealing and consistent end product.
One of its biggest advantages is shelf life extension. Because it maintains emulsion stability and resists breakdown during storage, manufacturers can deliver products that stay fresh-looking and stable for longer, even through temperature changes. Compared to some other modified starches, E1450 holds up well during both heat processing and freeze–thaw cycles, making it more versatile in manufacturing.
When lined up against other starch derivatives, E1450 often stands out for:
- Strong emulsifying ability – better than most native starches.
- Improved freeze–thaw stability – reduces watery separation in frozen goods.
- Consistent viscosity – maintains the same thickness over time.
- Neutral taste – doesn’t alter flavour profiles.
This combination of properties makes E1450 a go-to choice for UK food producers looking for a multifunctional additive that can enhance texture, stability, and overall product quality.
Common applications and food products containing E1450
E1450 starch sodium octenyl succinate is used in a wide range of everyday foods here in the UK. You’ll often find it in products where a smooth, stable texture is key and where ingredients need to stay well‑mixed over time.
Where it’s commonly found
- Dairy products – such as flavoured yoghurts, cream desserts, ice creams and milk drinks, to help prevent separation and give a consistent mouthfeel.
- Sauces and dressings – particularly creamy dressings, mayonnaise, gravies and cooking sauces, where it works as an emulsifier and thickener to keep oil and water phases blended.
- Bakery – in cake fillings, custards and glazes, improving texture and maintaining moisture during shelf life.

Consumer Concerns and Myths About E1450
When it comes to starch sodium octenyl succinate (E1450), there’s a fair bit of confusion. Some people worry about “chemical additives”, while others assume all modified starches are unhealthy. In truth, many of these concerns stem from misconceptions or a lack of clear labelling knowledge.
Common Misconceptions Debunked
- “E1450 is unsafe because it’s synthetic” – E1450 is derived from natural starches (like maize or tapioca) and then modified for better performance. This modification is well‑researched and approved by global food safety authorities.
- “It must contain gluten” – Most commercial E1450, including that used by Taichy Food, comes from gluten‑free sources, making it suitable for coeliacs.
- “It’s bad because it’s an E number” – An E number simply means it’s been tested and approved for use in food within the UK and EU.
How to Understand Food Labels
- Look for “modified starch (E1450)” in the ingredients list.
- If you follow a specific diet (gluten‑free, vegan, halal), check for sourcing information — many suppliers, including Taichy Food, provide full transparency.
- Compare with other additives — E1450 is often chosen over synthetic emulsifiers because it’s starch‑based.
