What is Food Grade Glycerin and Why Does It Taste Like a Cloud?

Food grade glycerin, a versatile and widely used substance, is a clear, odorless, and sweet-tasting liquid derived from natural fats and oils. It is a type of glycerol that has been purified to meet the stringent safety standards required for use in food, pharmaceuticals, and cosmetics. But what makes it so special, and why does it feel like you’re eating a cloud when you consume it? Let’s dive into the fascinating world of food grade glycerin and explore its many uses, benefits, and quirks.


What Exactly is Food Grade Glycerin?

Food grade glycerin, also known as glycerol, is a sugar alcohol that occurs naturally in plants and animals. It is produced through the hydrolysis of fats and oils, or as a byproduct of biodiesel production. The “food grade” designation means it has been purified to remove impurities and contaminants, making it safe for human consumption. Unlike industrial glycerin, which may contain harmful chemicals, food grade glycerin is non-toxic and widely used in the food industry.


The Many Uses of Food Grade Glycerin

  1. In Food and Beverages
    Food grade glycerin is a popular additive in the food industry due to its ability to retain moisture, enhance texture, and act as a sweetener. It is commonly found in baked goods, candies, and beverages. For example, it prevents ice crystals from forming in frozen desserts and keeps baked goods soft and fresh for longer. Its sweet taste, which is about 60% as sweet as sugar, makes it a popular choice for low-calorie and sugar-free products.

  2. In Pharmaceuticals
    Glycerin is a key ingredient in many medications, including cough syrups, lozenges, and suppositories. Its humectant properties help retain moisture, making it ideal for soothing dry or irritated tissues. It is also used as a solvent for flavors and active ingredients in liquid medications.

  3. In Cosmetics and Personal Care
    Food grade glycerin is a staple in skincare products like lotions, creams, and soaps. It attracts moisture to the skin, keeping it hydrated and soft. Its non-irritating nature makes it suitable for sensitive skin, and it is often used in products designed for eczema or psoriasis.

  4. In Vaping and E-Liquids
    Surprisingly, food grade glycerin is a key component in e-liquids used for vaping. It produces the thick vapor clouds that vapers love, and its sweet taste enhances the flavor of the e-liquid. However, its use in vaping has sparked debates about its safety when inhaled.


The Science Behind the “Cloud-Like” Taste

One of the most intriguing aspects of food grade glycerin is its unique mouthfeel. When consumed, it creates a smooth, almost ethereal sensation on the tongue, often described as “cloud-like.” This is due to its hygroscopic nature, meaning it attracts and holds water molecules. When you eat or drink something containing glycerin, it coats your mouth with a thin layer of moisture, creating that light, airy feeling. It’s like tasting a cloud, but without the rain.


Is Food Grade Glycerin Safe?

Yes, food grade glycerin is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used in moderation. However, excessive consumption can lead to side effects like bloating, diarrhea, or headaches. It is also important to note that while food grade glycerin is safe to eat, it should not be confused with industrial glycerin, which is not suitable for human consumption.


Environmental and Ethical Considerations

As the demand for food grade glycerin grows, so does the need for sustainable production methods. Many manufacturers are now turning to plant-based sources like coconut oil or soybean oil to produce glycerin, reducing reliance on animal fats. Additionally, the use of glycerin as a byproduct of biodiesel production helps reduce waste and promotes a circular economy.


Fun Facts About Food Grade Glycerin

  • Glycerin was first discovered in 1779 by Swedish chemist Carl Wilhelm Scheele, who heated olive oil with lead oxide. Thankfully, modern production methods are much safer!
  • During World War I, glycerin was used to make nitroglycerin for explosives. Today, it’s more likely to end up in your cupcake than on a battlefield.
  • Some people use food grade glycerin as a natural remedy for constipation, as it can draw water into the intestines and stimulate bowel movements.

FAQs About Food Grade Glycerin

Q: Can food grade glycerin be used in homemade skincare products?
A: Absolutely! Food grade glycerin is a popular ingredient in DIY skincare recipes due to its moisturizing properties. Just be sure to dilute it properly, as it can be sticky in its pure form.

Q: Is food grade glycerin vegan?
A: It depends on the source. Glycerin derived from plant oils is vegan, while glycerin from animal fats is not. Always check the label or contact the manufacturer to be sure.

Q: Can I substitute food grade glycerin for sugar in recipes?
A: While glycerin can be used as a sweetener, it is not a direct substitute for sugar. It lacks the bulk and caramelization properties of sugar, so it’s best used in combination with other sweeteners.

Q: Does food grade glycerin expire?
A: Glycerin has an indefinite shelf life if stored properly in a cool, dry place. However, it may absorb moisture from the air over time, so keep the container tightly sealed.


Food grade glycerin is a true multitasker, finding its way into everything from your favorite candy to your skincare routine. Its unique properties and versatility make it a valuable ingredient in countless industries. And while it may not actually be a cloud, its ability to create that light, airy sensation is just one of the many reasons it’s so beloved. So the next time you enjoy a soft cookie or apply a hydrating lotion, take a moment to appreciate the magic of food grade glycerin!
