Sorbitol: Exploring the Versatile Applications of Xylitol A Natural Sugar Alcohol In Industry

 

What is Sorbitol?

Glucitol is a sugar alcohol that is commonly used as a sweetener and food additive. It has around 60% of the sweetness of sucrose (table sugar) but has significantly fewer calories, with only around 2.6 calories per gram compared to 4 calories per gram for sucrose. This makes it an attractive sugar substitute for people watching their calorie or carbohydrate intake. Glucitol is also poorly absorbed by the human gastrointestinal tract, meaning that most of it passes through the digestive system undigested.

Production and Chemical Structure

Commercially, Glucitol is produced by the catalytic hydrogenation of glucose. This chemical conversion results in a six-carbon sugar alcohol with the chemical formula C6H14O6. The molecular structure of Glucitol contains five hydroxyl groups (OH), which make it soluble in water and give it sweetening properties. Unlike sugars, Glucitol lacks a ketone or aldehyde group and hence is not metabolized to release energy. This property means it does not significantly raise blood glucose or insulin levels when consumed.

Uses in Food and Beverages

Glucitol is widely used as a sugar substitute and sweetener in various food products. It is commonly found in sugar-free candies, chewing gums, mints, cookies, and other baked goods where it helps provide bulk, moisture and texture to low-sugar formulations. Due to its relatively lower sweetness intensity compared to sucrose, mixtures of Glucitol and other sweeteners like aspartame or sucralose are often used. Sorbitol Glucitol is also frequently incorporated into processed fruit preserves, spreads, and sauces to boost sweetness and act as a humectant to maintain moisture.

In the beverage industry, Glucitol serves as a sweetening and bulking agent in sugar-free soft drinks, juices, and other no-calorie beverages. It helps hydrate and stabilize suspensions while cutting calories. Examples include some diet sodas, sugarless lemonades, and light fruit punches. As an FDA-approved food additive, Glucitol is denoted by E number E420 and must be labeled on packaged food products containing it in the European Union and some other countries.

Other Common Applications

In addition to foods, Glucitol finds use as a stabilizer, thickener, and softening agent in various industrial and pharmaceutical applications. Toothpaste commonly contains Glucitol as it helps provide texture and body while having a preventative effect on tooth decay when combined with fluoride. Glucitol is also frequently employed as an excipient (inactive ingredient) in chewable or liquid medications due to its sweetness, solubility in water and non-cariogenic properties. Examples include pediatric vitamins, cold/cough syrups, laxatives, anti-acids and antacids.

Cosmetics represent another domain where sorbitol serves as a viscosity regulator, skin-conditioning agent and humectant in hair conditioners, hand creams, lip balms and more. In the manufacturing industry, it sees use as a plasticizer and softener to make plastics, rubbers and certain polymer products more flexible. Glucitol's bactericidal properties further make it useful as a preservative in foods, pharmaceuticals and personal care items.

Health Effects and Side Effects

When consumed in moderation, Glucitol generally has few adverse health effects for most people. However, in large quantities it can cause gastrointestinal issues like bloating, gas and diarrhea due to its poorly absorbable nature. Issues are more common in people with irritable bowel syndrome or inflammatory bowel disease. A daily intake tolerance of 20 grams or less is recommended to avoid possible side effects. Diabetics and those watching their glycemic levels also benefit from Glucitol's low impact on blood sugar and insulin levels.

However, regular long-term intake is not without risks. Excessive Glucitol consumption has been linked to potential deficiencies in minerals like calcium due to its osmotic laxative effects over time. There are also concerns about Glucitol potentially promoting the growth of oral bacteria and contributing to dental caries. All sugar alcohols provide fewer digestible calories than regular sugars, but are not calorie or carb-free. With around 2 calories per gram, high amounts may still affect weight control efforts. People sensitive to FODMAPs would also do best avoiding large Glucitol quantities.

Assessing Safety and Future Outlook

The Food and Drug Administration considers Glucitol to be generally recognized as safe (GRAS) for use in food, beverages and oral care products. It is approved by regulatory bodies worldwide and intakes under daily limit raise no significant safety issues for most individuals. However, its properties also mean Glucitol needs to be carefully accounted for in low-calorie, diabetic-friendly, and low-carb diets or formulas.

 

Glucitol yields while lowering costs to both industry and consumers. Though not a complete sugar replacement, Glucitol has proven itself a versatile food additive and provides alternatives for people watching ingredients. It will likely remain an ingredient of choice where a sugar-free or reduced-calorie sweetener profile fits the need.
