Glycerol ester of wood rosin, which is also known as E445, is a food additive composed of a mixture of different fatty acids used as an emulsifier and structuring agent in processed cheese, sauces and salad dressings, among others. Glycerol ester of wood rosin is not really a sugar (it only contains a small number of glucose units), but it has similar properties to sugar. It can be used as a non-nutritive sweetener to replace sugar or corn syrup in various foods such as baked goods, powdered drink mixes, dairy products, and other commercially processed foods.
What is glycerol ester of wood rosin?
Glycerol ester of wood rosin is a synthetic resin made from the combination of a natural plant-derived resin and glycerol. It is produced by the reaction of wood rosin or tall oil (resin) with glycerol. The reaction creates a resin that has a similar molecular structure to natural rosin but with better properties such as higher viscosity, reduced tackiness, and enhanced thermal stability.
Glycerol ester of wood rosin is used in adhesives to improve their properties and performance. It can be used as an adhesive itself or as a modifier that improves the performance of other adhesives.
Glycerol esters are also known as glyceryl esters, glycol esters, or polyglycol esters (PGEs).
How is glycerol ester of wood rosin made?
Glycerol ester of wood rosin is a natural, non-petroleum based additive used in many industries as a thickener and lubricant. The process for making this product is fairly simple, and it involves only three steps:
- Wood rosin: Wood Rosin is obtained from the sap of trees and shrubs by collecting the gum that exudes from incisions made in the trunk or branches. This gum contains resin acids, which are insoluble in water but soluble in alcohol. When the alcohol evaporates, it leaves behind an almost pure resin.
- Glycerol: Glycerol, also known as glycerine or glycerin, is a colorless, odorless syrupy liquid that can be extracted from fats and oils. It’s one of the major components of vegetable oil (along with stearic acid), which makes it easy to come by commercially.
- Acetylation: Acetylation involves adding an acetyl group to another compound (such as glycerol) through the use of an acetyl transferase enzyme. This process occurs naturally in our bodies when we digest certain foods like milk or soybeans;
What is wood rosin?
Wood rosin is a natural product that comes from trees. It’s a soft, sticky substance that’s tapped from the resin glands of certain types of pine trees. The two most common types are larch and fir, but you can also find wood rosin from spruce, cedar and hemlock trees.
In addition to being used as a raw material for making varnishes, wood rosin is also used in food products such as chewing gum or candy. It’s also commonly used in cosmetics, waxes and polishes.
Rosin is composed of many different components including abietic acid, heptanoic acid, palmitic acid, stearic acid and oleic acid. The exact composition depends on the source of pine resin used to create it (i.e., different species of pine trees).
Rosin can be extracted from any number of different species of pine trees including black spruce, eastern white cedar, eastern white pine and red spruce.
What is glycerol ester of rosin?
Glycerol ester of rosin is a natural by-product of the rosin manufacturing process. It is a liquid that is soluble in water. Glycerol ester of rosin has many uses in industries such as cosmetics and food processing.
Glycerol esters are used as emulsifiers, stabilizers, and softeners in foods such as ice cream, baked goods, frozen dairy desserts, and chewing gum. They also act as humectants (moisturizers) that help keep food moist during storage and transit.
Glycerol esters are used in cosmetics and personal care products as emollients (softening agents), solvents, thickeners and gelling agents, viscosity increasing agents, opacifiers (gloss enhancers), stabilizers (keep formulas from separating), humectants (moisturizers), film formers (make skin look more smooth), anti-foaming agents (smooth out lathers), moisturizing agents, emulsifiers/emulsion stabilizers (keep ingredients uniform), thickening agents (add body to thin lotions & creams), preservatives/antioxidants, solubilizing agents (make oil soluble into water based products).

What is glycerol ester of wood rosin used for?
Two main food uses
Food grade ester gum can be used as chewing gum base components and as an emulsifier, stabilizer, and density adjustment agent for beverages. In the ingredient section, its name may be shortened to rosin glycerol ester.
Brominated vegetable oil replacement
This ingredient helps prevent brominated vegetable oil (BVO) from being added to products like sports drinks and sodas, because BVO has been banned in Europe due to safety concerns. Glycerol ester of wood rosin is an alternative that gives drinks the same consistency without any health risks associated with BVO consumption.
Is glycerol ester of wood rosin safe to consume?
It has been approved for use as a food additive by the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as other regulatory bodies.
Glycerol ester of wood rosin is safe for consumption, according to the Food and Drug Administration (FDA). Glycerol ester of wood rosin has been approved as a food additive under 21 CFR 172.839 and is listed on the FDA website as GRAS (generally recognized as safe).
The European Food Safety Authority (EFSA) also reviewed glycerol esters of wood rosins and concluded that they are safe for human consumption at levels up to 1g/kg body weight per day.
According to Commission Regulation (EU) No 231/2012, ester gum (E445) is an authorised food additive, and it is in the category of “additives other than colourings and sweeteners”.
Safety revaluation in 2018
In 2018, EFSA reevaluated the safety of ester gum derived from approved sources Pinus palustris and Pinus elliottii, as well as unauthorized sources Pinus Halepensis and Pinus brutia. Conclusions are as follows:
Pinus palustris (longleaf pine) and Pinus elliottii (slash pine) have a current acceptable daily intake (ADI) of 12.5 mg/kg body weight per day due to the overall toxicity database and lack of reproductive and developmental toxicity data.
Due to the unknown fractions of glycerol monoesters, free resin acids, and neutrals, the ester gums from Pinus Halepensis and Pinus brutia could not be tested for safety. These fractions are generally tested for toxicology.
Authorised uses and levels
With maximum levels ranging from 50 to 320 mg/kg, it can be found in the following foods:
- Entire fresh fruit and vegetables
- Confectionery including breath freshening microsweets
- Flavoured cloudy drinks
- Cloudy spirit drinks

Glycerol Ester Of Wood Rosin in Food
Food manufacturers use glycerol ester of wood rosin to thicken foods such as ice cream, baked goods and salad dressings. It also helps maintain moisture content in foods like cakes and breads. The additive also acts as a preservative by preventing the growth of bacteria in foods that are stored at room temperature for long periods of time.
Glycerol ester of wood rosin is commonly used in baked goods such as breads, cakes, cookies and pies. It may also be used to help prevent separation in sauces during cooking or freezing processes.
What is Glycerol of Wood Rosin?
Glycerol of Wood Rosin
Glycerol of Wood Rosin is a natural organic rosin that is derived from the gum of the pine tree. It has been used for thousands of years as a natural food additive and preservative.
In addition to its use as a food additive, it has also found application in modern day industries due to its ability to create heat and pressure when combined with other materials such as wood chips or sawdust. This combination creates a sticky substance that can be molded into various shapes and forms.
Glycerol of Wood Rosin is primarily used in the manufacturing of chewing gum because it acts as an emulsifier that allows different ingredients in gum like flavorings and sweeteners to mix with each other easily without separating into layers during storage or while chewing the gum.
