Mono-Diglycerides vs. SSL in Baking

Date:2025-05-30

Read:

Mono-Diglycerides and SSL emulsifiers are both vital and efficient tool for commercial baking production. They are greatly helpful for improving the texture, volume, and shelf life of baked goods. While they may appear similar, each has distinct properties that affect product performance in different ways. Let`s take a complete overview about the similarities and difference between them, and help you decide which emulsifier is best suited for your specific baking needs.

What Are Mono-Diglycerides?

Mono- and diglycerides are derived from glycerol and edible fatty acids. They are generally considered safe and are commonly labeled as E471 in ingredient lists.

Key Functions:

Improve crumb softness and texture
Delay staling in breads and cakes
Act as dough conditioners
Help with oil and water emulsification

Typical Applications:

Sandwich bread
Cakes and muffins
Frozen doughs

Advantages:

Cost-effective
Widely compatible with both fat- and water-based ingredients
Neutral taste and odor

What Is SSL (Sodium Stearoyl Lactylate)?

Sodium Stearoyl Lactylate, or SSL, is an anionic emulsifier made from lactic acid and stearic acid. It's often listed as E481 on product labels.

Key Functions:

Strengthens gluten structure
Improves dough tolerance to mechanical stress
Increases loaf volume
Enhances crumb structure

Typical Applications:

White bread and buns
Enriched dough (e.g. brioche)
Hamburger buns

Advantages:

Excellent for yeast-raised products
Improves gas retention and dough stability
Helps extend shelf life

Mono-Diglycerides vs. SSL: A Side-by-Side Comparison

Feature	Mono-Diglycerides	SSL
E number	E471	E481
Function	Emulsification, anti-staling	Dough strengthener, volume enhancer
Best for	Cakes, soft breads	Yeast-raised breads, buns
Water solubility	Low	High
Gluten interaction	Minimal	Strong
Shelf-life improvement	Moderate	Strong
Dosage (typical)	0.3% – 0.5%	0.25% – 0.5%

Which One Should You Use?

It depends on your product goals:

If you're making cakes or soft enriched breads, mono-diglycerides may be the better choice to improve softness and moisture retention.

For artisan-style loaves, buns, or products requiring dough strength and higher volume, SSL offers better performance thanks to its interaction with gluten.

In many commercial applications, bakers actually use both in combination to achieve an ideal balance of softness and strength.

In Conclusion

Both mono-diglycerides and SSL are powerful emulsifier for baking products—but they`re not interchangeable. Understanding their distinct functions helps ensure your final product has the texture, structure, and shelf life your customers expect.

Whether you're formulating a new product or trying to troubleshoot dough performance, choosing the right emulsifier (or combination) can make all the difference. Need help choosing the best one for your formulation? Get in touch with CHEMSINO —we`ll help you build a better bake.
