Granulated white sugar, the favorite and most widely available sweetener, is extracted from sugar cane and sugar beet plants. We call it simply "sugar" or table sugar, no matter where it comes from, and most of us cannot distinguish one from the other.
However, it turns out some consumers argue they have a different aroma, caramelization, and baking performance. This blog post explores what could be responsible for those differences. Also, when it comes to culinary performance, is cane sugar better or worse than beet sugar?
Impurities: Some Say "Tiny But Meaningful"
Table sugar is considered one of the purest food products. Chemically speaking, it's an astonishing 99.95 percent pure sucrose, regardless of whether it comes from cane or beet. The remaining 0.05 percent consists of mostly water plus what is called impurities.
Impurities are undetectable by the vast majority of consumers because of their minuscule amounts. However, the presence of those substances is the only possible explanation as to why some people claim they can detect the source of their table sugar and that beet sugar has a different culinary performance than cane sugar.
Impurities include anything other than sucrose and result from: (1) the raw material, and (2) the process used to produce each sugar. The composition of impurities in cane sugar is not the same as in beet sugar. Learn why next.
What Are The Differences?
The composition of impurities in cane sugar is not the same as in beet sugar for two reasons:
1) The Raw Material
The slight difference in composition between cane and beet sugars results from the fact that different chemical components are present in each plant. The raw material for cane sugar is the whole stem of the cane, which grows above ground. On the other hand, the raw material for beet sugar is the entire root of the plant and so, grows underground. Other dissimilarities between cane and beet plants are listed below.
Note that the terms sugar cane and sugar beet are made up of two words. To simplify, I connect the words and use sugarcane and sugarbeet or I simply use cane and beet.
2) The Process Used to Make Sugar
Another reason why cane and beet sugars are not exactly the same is a result of the process used to produce each one. The differences in composition between the crops require different refining methods and chemicals.

Watch the video in a Sugar Refinery here.
The processes and the chemicals used to refine cane and beet sugars are not the same because their starting material — cane or beet juices — have different compositions. Here are some quick facts about cane and beet juices:
Both are made up of two substances that must be separated: sugar (sucrose) & nonsugars.
Nonsugars – referred to as "impurities" – include all dissolved substances except sucrose. Impurities are unwanted and have to be removed. They interfere with the sweet taste and decompose into less palatable chemicals during the concentration process of the juice. They consist of glucose, fructose, proteins, complex carbohydrates, coloring substances, and minerals.
After their refining process, white sugar (99.95 percent sucrose) goes out as the final product, and most nonsugars (impurities) accumulate in thick dark syrups, aka molasses, after being centrifuged. Still, a minuscule amount — about 0.02 percent — remains around the sucrose crystals. And those tiny impurities are responsible for the argument that cane & beet sugars do not have the same aroma, caramelization, and baking performance.
Cane & Beet Sugars: Interchangeable?
Refined sugar from beet & cane may be used interchangeably for all purposes. I list below some facts about them to be able to draw a comparison:
Both cane and beet sugars are 99.95 percent sucrose, even though they come from different plants. They have a minuscule fraction of impurities (approximately 0.02 percent) that are different. In regards to human nutrition and health, there is no difference between white cane and beet sugars.
Differences in aroma, caramelization, and baking performance have been reported, even though most people cannot notice any discrepancies between table sugar from beet and cane. The taste and sweetness are the same for both sugars — a clean, pleasant sweetness from start to finish, that hits quickly without lingering. No aftertaste.
Some consumers have reported that cane sugar caramelizes better than beet sugar. Very experienced users claim beet sugar burns quicker to black making it harder to work with it than cane sugar. Reports that there is a slight difference in baking performance have also been made. Again, these culinary differences are undetectable by the vast majority of consumers.
Some people claim beet sugar has a characteristic off-aroma, referred to as an earthy odor. Considering that beet is a root, one possible explanation could be the aroma of beet sugar originates from the fact that beet grows underground. Most of us cannot discriminate between the aroma of cane & beet sugar.
In 2014, two studies by University of Illinois researchers, published in the Journal of Food Science, compared white granulated cane and beet sugars. The first study showed that beet sugar's aroma is different than that of cane sugar. Beet sugar was characterized by off-dairy, oxidized, earthy, and barnyard aromas and by a burnt sugar aroma-by-mouth and aftertaste. In contrast, cane sugar showed a fruity aroma-by-mouth and sweet aftertaste.
In a second study, researchers compared foods made with beet and cane sugars. They concluded that significant differences between the sugar sources were identified when incorporated into simple syrup. No difference was observed in sugar cookies, pudding, whipped cream, and iced tea.
In the United States, the price of refined sugar from cane is similar to that of beet, even though production costs of cane sugar are lower than that of beet sugar. During the month of January 2020, the average price of white granulated sugar in two stores in Richmond, Virginia was 0.75 cents per pound.
Is it Cane Sugar? Beet Sugar? A Blend?
The familiar table sugar might be produced from sugar beet in a Sugar Factory or from raw sugar in a Sugar Refinery. Have you ever noticed that sugar producers usually don't state if their sugar is from sugarcane or sugarbeet? The reasons for that are listed below:
Producers of cane and beet sugars are not required to mention the source of their product (see image below) because, by law, only sweeteners derived from cane and beet should be declared on food labels as "sugar".
If you see "sugar" listed in the ingredients list, it must be a sweetener from cane and/or beet—and it comprises more than 40 sweeteners— because, as defined by the Food and Drug Administration, sugar shall refer to sucrose obtained from cane and beet only.
Typically, if the label of a white sugar does not identify if it is from cane or beet (as in most store brands), the product is from beet or a blend. For those brands, portions of each in any given serving vary over time based on price from the producers so that it can be cane one time, but beet another, or both cane and beet mixed. If a brand is always cane, it will often be labeled as such. Keep reading to find out why they are blended. The image below shows some common brand names of cane sugar, beet sugars, and blends.
Why Are Cane & Beet Sugars Blended?
Blends of cane and beet sugars are common because many sugar producers do not sell their products directly to consumers. They have their products sold and distributed by sugar marketing organizations, which may blend beet and cane sugar, based on price and availability. The top marketers in the country include:
Domino Foods Inc (DFI) and Imperial Sugar are the top distributors of refined sugar from sugar cane in the country. DFI is owned by American Sugar Refining (ASR Group), based in Florida, which claims to be the leader in the production of refined sugar. DFI's brand names include Florida Crystals and sister brands C&H and Domino. Imperial Sugar is a subsidiary of Louis Dreyfus Company LLC and a manufacturer and marketer of sister brands Imperial Sugar and Dixie Crystals.
United Sugars Corp (United) is the nation’s second largest marketer of refined sugar. It provides beet & cane sugar, distributing almost 25% of the total refined sugar in the country. United is a cooperative owned by 3 producers: American Crystal (beet sugar), Minn-Dak Farmers Coop (beet sugar), and US Sugar Corp. (cane sugar). Top brand: Crystal Sugar.
Cargill claims to be the leading marketer of refined sugar in the country. It sells and distributes cane & beet sugar from the U.S. and Mexico, representing the following sugar producers: Louisiana Sugar Refining (cane sugar), Southern Minnesota Beet Sugar Coop, Spreckels Sugar Co. (beet sugar), Wyoming Sugar Co. (beet sugar), Zucarmex (cane sugar from Mexico), and other producers from Mexico. Top Brand: Café Delight.
Who Makes Beet & Cane Sugars?
In 2018–19, the U.S. produced about 8 million tons of sugar annually, ranking in sixth in global production surpassed by Brazil, India, European Union, Thailand, and China. It also imports almost 3 million tons. American sugar producers and processors receive a variety of government supports. An overview of the sugar industry in the United States is as follows:
The top producers of refined sugar from sugar cane are American Sugar Refining (ASR Group) and Imperial Sugar. ASR is owned by the Florida Crystals Corporation and the Sugar Cane Growers Cooperative of Florida. Imperial Sugar Company is a wholly-owned subsidiary of Louis Dreyfus Company LLC.
American Crystal Sugar Company is the largest beet sugar producer in the U.S. It is a coop based in Minnesota and owned by almost 3000 beet growers.
Cane and Beet Sugars: GMO-free?
The United States is one of the only countries in the world that grows both cane and beet plants. Currently, only genetically modified varieties of sugar beets are planted. Read the statement of an American coop of 850 beet growers explaining why they support GMO technology here.
Sugar cane used to be a non-GMO crop, but not anymore. Since 2017, Brazil has been growing GM cane. That is relevant to us Americans because Brazil is one of the top cane sugar producers and exporters of crude raw sugar in the world. And the United States is the second top importer of crude raw sugar, which is used to produce our refined sugars.
Be aware that sugar itself is GMO-free. Once refined, sugar no longer has any traces of GMOs in it. A sucrose molecule is identical whether it comes from GMO plants or not.
Cost of Cane vs Beet Sugars
The price of cane sugar we pay in stores is similar to that of beet sugar. In January of 2020, the average cost of white refined sugar (granulated, fine granulated, and extra fine granulated) I paid in stores across the city of Richmond, Virginia was 75 cents per pound. It varied from 28 cents to $1.30 a pound.
I also bought two imported refined beet sugars and paid about $4 per pound. According to the label on the back of the package of NOW non-GMO Beet Sugar and NOW Organic Beet Sugar, they are imported from Austria. Europe is the world's leading beet sugar producer. It grows only non-GMO sugar beets but no sugar cane is planted there. Also, sugars made from GM cane and GM beet cannot be sold in Europe.
Chemically speaking, both cane and beet sugars are about 99.95 percent sucrose. The remaining 0.05% is water plus impurities. The composition of impurities in beet sugar is not the same as in cane sugar because they come from different crops which require different refining methods. Most of us cannot detect this minuscule amount of impurities, so both cane and beet sugars will look, taste, smell, and perform in the kitchen exactly the same way.
Table sugar from beet and cane may be used interchangeably for all purposes. The price of cane sugar you pay in stores is similar to that of beet sugar (unless it is imported). One is not healthier or better for you than the other.
