Pectin is a fascinating substance that has been used for centuries as a gelling agent in food.
It’s derived from plant cells and can be found naturally in certain fruits, but most commercial pectins are derived from citrus peels.
Pectin is commonly used in jams, jellies, and preserves to create a fibrous network capable of supporting liquids and forming the gel necessary for these delicious treats.
But is pectin a sugar alcohol?
In this article, we’ll explore the properties of pectin and answer this question once and for all.
So sit back, relax, and let’s dive into the world of pectin!
Is Pectin A Sugar Alcohol?
No, pectin is not a sugar alcohol. While both pectin and sugar alcohols are commonly used in food products, they are two distinct substances with different properties.
Pectin is a complex carbohydrate that forms gels when dissolved in water under suitable conditions. It is derived from the protopectin found in the middle lamellae of plant cells and is commonly used as a gelling agent, thickening agent, and stabilizer in food.
On the other hand, sugar alcohols are a type of low-calorie sweetener that are often used as a sugar substitute in food products. They are derived from sugars but undergo a chemical process that converts them into alcohol. Examples of sugar alcohols include xylitol, erythritol, and sorbitol.
While pectin and sugar alcohols may be used together in some food products, they are not the same thing.
What Is Pectin And How Is It Made?
Pectin is a group of substances that are derived from the protopectin found in the middle lamellae of plant cells. Protopectin is insoluble, but it is converted to soluble pectin as fruit ripens or is heated in an acid medium. Pectin is a negatively charged colloid in an acid fruit substrate. As sugar is added to this colloid, the pectin–water equilibrium breaks down, and a fibrous network capable of supporting liquids is established. The fiber network forms the gel necessary for jams, jellies, and preserves.
Pectin can be produced from many fruits, or other plant tissues such as beetroots, but most commercial pectins are derived from citrus peels by precipitating the pectin from solution with alcohol. Pectin is a reversible colloid, which means that it may be dissolved in water, precipitated, dried, then redissolved without alteration of its physical properties.
Dry pectin does not readily go into solution. On the addition of water to dry pectin, paste-like lumps are formed. Solution is greatly facilitated by heating the water or juice, then adding a pectin and sugar mixture. Pectin which has been thoroughly mixed with 10 times its weight of sugar will readily go into solution in hot water, forming a nearly clear solution.
Various pectins are produced for the preserving trade. These pectins may be classified as rapid-set, slow-set, or by the weight of finished jelly that one unit weight of pectin will produce. Rapid-set pectin forms gels at higher temperatures than slow-set pectin. Rapid-set is preferred for jams and preserves because it reduces the likelihood that the fruit component will rise to the surface before the gel is set. Slow-set pectin is often preferred for jelly production because handling of the jars after the jelly has firmly but not finally set is less apt to damage the jelly’s texture and firmness.
The Role Of Pectin In Food
Pectin plays a crucial role in the food industry as a gelling agent, thickening agent, and stabilizer. Its classical application is giving the jelly-like consistency to jams or marmalades, which would otherwise be sweet juices. Pectin also reduces syneresis in jams and marmalades and increases the gel strength of low-calorie jams.

Apart from its use as a gelling agent, pectin has wide applications in the food industry. It is used as an emulsifier, thickener, stabilizer, and fat or sugar replacer in low-calorie foods. Pectin and pectin-derived oligosaccharides can also be used as an important ingredient in functional foods. In recent years, pectin polymers have been used as edible films or coatings that act as natural barriers for exchange of moisture, gases, lipids, and volatiles between food and environment, protecting fruits and vegetables from microbial contamination.
Understanding Sugar Alcohols
Sugar alcohols, also known as polyols, are a type of carbohydrate that are used as sweeteners and bulking agents in many food products. They are often used as a sugar substitute in processed foods to provide a sweet taste without the added calories. Sugar alcohols occur naturally in some fruits and vegetables, but most are produced industrially by processing other sugars such as glucose.
Despite their name, sugar alcohols are not actually alcoholic beverages. They have a chemical structure that is similar to both sugar and alcohol, but they do not contain ethanol. Sugar alcohols are about 25-100% as sweet as regular sugar, but they have fewer calories and do not cause the same negative effects on blood sugar levels and dental health.
Some common types of sugar alcohols include sorbitol, xylitol, mannitol, isomalt, maltitol, lactitol, and hydrogenated starch hydrolysates. These sweeteners are often used in sugar-free and reduced-sugar baked goods, desserts, candy, and other sweet treats. They can also be found in natural foods such as fruits and vegetables in small amounts.
Sugar alcohols are considered low digestible carbs because they are not completely absorbed by the small intestine. Instead, they travel to the large intestine where they are fermented by bacteria. This process may contribute to a healthy digestive system by promoting the growth of beneficial bacteria.
While sugar alcohols may be a good alternative to regular sugar for those trying to lose weight or manage blood sugar levels, they do have some potential side effects. Consuming large amounts of sugar alcohols may cause digestive issues such as bloating, gas, and diarrhea. It is important to consume them in moderation and to be aware of their presence in processed foods.
The Health Benefits And Risks Of Pectin And Sugar Alcohols
Pectin and sugar alcohols have both been researched for their potential health benefits and risks.
Pectin, like other soluble fibers such as those found in oatmeal and psyllium husks, has been shown to help lower LDL “bad” cholesterol, though the effect is small. It may also have a role in cancer care, as a small study of men with prostate cancer showed that MCP (modified citrus pectin) appeared to slow the growth of their cancer. Pectin has also been used to control diarrhea, but the FDA has determined that the available evidence does not support this use.
As for sugar alcohols, they provide fewer calories than regular sugar and may be beneficial for those trying to lose weight by reducing calorie intake. They also do not cause tooth decay like regular sugar because the bacteria in the mouth do not feed on them. Sugar alcohols are not fully absorbed and digested by the body, resulting in less of an increase in blood sugar. This can be beneficial for people with diabetes who want to maintain better blood sugar control while still enjoying sweet treats in moderation.
However, consuming high amounts of some sugar alcohols, such as sorbitol, can cause bloating and diarrhea, especially if consumed in large amounts. It is important to note that optimal doses for MCP have not been established for any condition, and the quality of active ingredients in products containing MCP varies from maker to maker.
Other Uses For Pectin
Aside from its use as a gelling agent and stabilizer in food, pectin has other potential benefits and uses. One of the most notable benefits of pectin is its ability to aid in digestion. As a soluble fiber, pectin forms a gel-like substance in the digestive tract which can soften stool and speed up the transit time of material through the digestive system. This can help reduce symptoms of constipation and improve overall gut health.
Pectin has also been studied for its potential to improve blood sugar and blood fat levels. Some studies suggest that pectin may help regulate blood glucose levels by slowing down the absorption of carbohydrates in the small intestine. This can be particularly beneficial for individuals with type 2 diabetes or those at risk for developing the condition.
In addition, there is some evidence to suggest that pectin may have anticancer properties. Pectin has been shown to inhibit the growth of cancer cells in test tubes and animal studies, although more research is needed to determine its effectiveness in humans.
Finally, pectin has been used in some medical applications as a hemostatic agent to reduce bleeding. While there have been some reports of success with this use, more research is needed to determine its safety and effectiveness.
