All glycerides consist of a glycerol molecule and one or more fatty acid chains:

• monoglycerides have one fatty acid chain
• diglycerides have two fatty acid chains
• triglycerides have three fatty acid chains

According to an evaluation by the World Health Organization (WHO), mono- and diglycerides make up approximately 1 percent of the glycerides you consume. They occur naturally in certain oils and are also found in processed foods.

Most of the fats you eat, including plant-based oils and animal fats, are made up of triglycerides. Triglycerides play an important role in heart health. Doctors usually check triglyceride levels during routine cholesterol tests.

Did you know?

Enzymes in your body break triglycerides down into mono- and diglycerides during digestion. When mono- and diglycerides enter the bloodstream, they are transformed back into triglycerides.

Mono- and diglycerides are emulsifiers, which means they help oil and water to blend. As a result, they’re commonly used as food additives. Small quantities are often added to packaged and frozen foods to improve texture and stability, prevent oil from separating, and extend shelf life.

You’ll find mono- and diglycerides on the ingredient lists of packaged and processed foods. They may go by other names, including:

• distilled mono- and diglycerides
• ethoxylated mono- and diglycerides
• mono- and diglyceride esters
• diacylglycerol oil

Mono- and diglycerides can be found in processed foods such as:

• bread
• tortillas
• baked goods
• nut butters
• margarine
• shortening
• mayonnaise
• coffee creamers
• frozen dinners
• ice cream
• frosting
• whipped topping
• candy
• soft drinks
• chewing gum
• some processed meats and meat substitutes

Grocery store aisles aren’t the only place you’ll find these additives. Fast food chains and restaurants also serve menu items containing mono- and diglycerides. Common sources include:

• margarine used for cooking
• bread
• breadsticks
• buns
• croissants
• biscuits
• tortillas
• fries
• ice cream
• milkshakes
• frappes

Mono- and diglycerides help oil and water to blend. Because of this, they can be used to improve the texture or consistency of foods. For example, they help:

• improve the consistency of margarine
• prevent the oil in peanut butter from separating
• give ice cream a creamier consistency
• reduce stickiness in candy

In processed meats and sausages, they help to ensure fat is well-distributed.

They’re added to baked goods to slow the staling process. They also improve texture, ensuring bread is doughy and elastic.

Trace amounts of both mono- and diglycerides are naturally present in some seed-based oils, such as:

• olive oil
• grapeseed oil
• cottonseed oil

Concentrations are low so they are difficult to isolate. Because of that, mono- and diglycerides are sourced through a chemical reaction that begins with a triglyceride-containing animal fat or vegetable oil. With the addition of heat and an alkaline catalyst, triglycerides rearrange into mono- and diglycerides. The result is a substance that contains a random mixture of mono-, di-, and triglycerides.

Next, mono- and diglycerides are separated through distillation. They may undergo further processing before they are added to your food.

The consumption of trans fat has been linked to an increased risk of heart disease and stroke. According to the Centers for Disease Control and Prevention, avoiding artificial trans fat consumption could prevent between 3,000 and 7,000 heart disease-related deaths in the United States each year. Learn more about good fats, bad fats, and heart disease.

Since , the U.S. Food and Drug Administration (FDA) has been taking steps to remove artificial trans fat from all foods. This includes a ban, announced in , on partially hydrogenated oils (PHOs). PHOs are the most ubiquitous source of trans fat in food. Food manufacturers have until to remove all trans fat from their products.

Mono- and diglycerides contain small amounts of trans fat. They’re classified as emulsifiers and not lipids, so the FDA ban doesn’t apply to them. As trans fat is phased out, food companies may turn to mono- and diglycerides as low-cost alternatives.

According to the FDA, mono- and diglycerides are generally recognized as safe. They can be used in food without limitation, provided the manufacturing process is satisfactory.

The Center for Science in the Public Interest also describes them as safe, while a WHO report indicates that there are no harmful effects associated with their consumption.

That doesn’t necessarily mean they’re good for you. Currently, there’s no way of knowing how much trans fat is in products with mono- and diglycerides listed on the label.

Food products with mono- and diglycerides are also likely to be high in other fats, as well as refined sugar and flour.

8 Points To Consider Before Choosing An Emulsifier

Good emulsifiers are vital components in food manufacturing due to their ability to create and maintain stable emulsions. This blog mainly focuses on eight factors to consider when choosing emulsifiers and the types commonly used in bread.

Properties Of Good Food Emulsifiers

Best emulsifiers exhibit unique attributes that significantly impact their functionality within food formulations. Emulsifiers possess a range of essential traits, including solubility, melting point, smoke point, plasticity, and flavor. These characteristics profoundly impact their efficacy in food processing, influencing everything from stability to texture and taste in the final product.
Therefore, before purchasing emulsifiers, consumers need to understand the following characteristics of emulsifiers to choose the most suitable ones:

1. Emulsification

The primary function of an emulsifier is to combine oil and water phases to form a stable emulsion. Therefore, emulsifiers must have good emulsification capacity to efficiently disperse and stabilize two immiscible components.

2. Solubility

Solubility, a key characteristic of good emulsifiers, delineates their capacity to dissolve in either water or oil. Emulsifiers are categorized as water-soluble or oil-soluble based on this trait. It holds immense significance in crafting stable emulsions, as emulsifiers facilitate the dispersion and stabilization of fat droplets in aqueous products or water droplets in oil-based formulations.

3. Melting Point

The melting point of good emulsifiers is like its "temperature switch" from solid to liquid. This matters a lot in cooking. Emulsifiers with higher melting points are great for hot stuff like baking or frying because they stay solid and stable when it's hot. But for cold treats like ice cream, emulsifiers with lower melting points are better. They help keep things smooth and creamy even when it's freezing.

4. Plasticity

Plasticity in emulsifiers refers to how easily they can be shaped or formed. Emulsifiers with high plasticity are flexible and can be molded into various shapes, making them ideal for creating specific textures or structures, such as smooth chocolate coatings or fluffy whipped toppings. Conversely, emulsifiers with lower plasticity are less flexible and are better suited for applications where a firmer structure is desired, such as certain types of margarine or spreads.

5. Flavor

Emulsifiers can influence the flavor of food products in different ways. Some emulsifiers have a neutral taste and don't noticeably affect the final flavor. However, others impart their distinct flavors, enhancing or complementing other ingredients. For instance, soy lecithin might introduce a subtle nutty note, while egg yolks can bring richness and depth to baked goods. It's essential to choose the right emulsifier to achieve the desired flavor profile in food products.

6. Safety

Good emulsifiers must comply with food safety standards, free from harmful substances or any adverse effects on human health. Comprehensive evaluations regarding their toxicity, allergenicity, and potential long-term impacts are necessary. CHEMSINO company's food emulsifiers are certified to comply with a variety of standards and regulations, ensuring their safety and quality. All emulsifiers have passed the RSPO, Halal & Kosher, ISO, and ISO certificates. Welcome to contact us for detailed quotes and free samples.

7. Regulatory Compliance

Good emulsifiers must adhere to local and international regulations, encompassing aspects like labeling requirements and usage restrictions. Their utilization must align with food safety standards and regulations to ensure the compliance and safety of the final product.

8. Cost-effectiveness

Cost is a significant consideration in emulsifier selection. The cost of emulsifiers should be reasonable and commensurate with the product's performance and effects to ensure that production costs remain within a reasonable range.

Common Emulsifiers In Baking

 

Distilled Monoglyceride (DMG)

Distilled Monoglyceride (DMG) is an organic compound, also known as glycerol monostearate. It is an emulsifier produced by distillation of glycerol and fatty acids. In the food industry, DMG emulsifier is commonly used as an emulsifier and stabilizer in bread, cakes, salad dressings, cookies, candies, ice cream, etc.
In bread, DMG emulsifier acts as an emulsifier and dough conditioner. It improves texture and volume by stabilizing dough structure and enhancing elasticity. It helps retain gas during fermentation, leading to a softer crumb and increased volume. DMG e471 also extends shelf life by retaining moisture and delaying staling. Overall, DMG emulsifier is crucial for high-quality bread with the desired texture, volume, and shelf life.

Lecithin

Lecithin, typically derived from sources like soybeans or egg yolks, serves as a natural emulsifier. It facilitates the blending of water and oil, enhancing the dough's flexibility and adhesiveness. This contributes to better dough shape retention and the formation of a uniform bubble structure during baking, resulting in increased bread volume and a softer texture. Utilizing lecithin enhances bread quality, making it softer, more enjoyable to eat, and extending its shelf life.

DATEM

DATEM, a robust emulsifier, improves dough elasticity and stability. It promotes the formation and expansion of air bubbles, leading to a softer and fluffier bread texture. DATEM emulsifier also enhances dough fermentation, speeding up the process and reducing production time. Moreover, it enhances the appearance of bread, giving it a more appealing layered and textured appearance.

Sodium Stearoyl Lactylate (SSL)

Sodium Stearoyl Lactylate is an emulsifier commonly used in food production. It helps stabilize food products by enhancing their mixing properties, resulting in a smoother and more uniform texture. 
SSL emulsifier is often found in baked goods such as bread. SSL emulsifier can enhance dough stability and viscosity. It facilitates the formation and distribution of air bubbles, resulting in a larger bread volume and a softer crumb. SSL emulsifier enhances dough handling, making it easier to work with. It also contributes to the flakiness and lightness of bread. Additionally, SSL helps bread retain moisture, improving its taste and extending its shelf life.

Sorbitan Monostearate Span60

Span 60 sorbitan monostearate is a food additive commonly used as an emulsifier in various food products. It helps to stabilize oil-in-water emulsions, preventing the separation of oil and water phases.
In bread, sorbitan monostearate serves as an emulsifier to improve the dough's handling properties and the texture of the final product. It helps in creating a finer and more uniform crumb structure, enhancing the softness and overall quality of the bread. Additionally, sorbitan monostearate can aid in dough conditioning, providing better gas retention during fermentation, and resulting in improved volume and texture of the bread.

Conclusion

Food emulsifiers are indispensable components in the food processing industry. They not only enhance the quality and stability of products but also increase product diversity and improve taste and appearance.
