2. SUGAR ALCOHOLS Function,Importance and uses of sugar alcohols 2

3. Function of sugar alcohols DEFINITION Sugar alcohols are organic compounds, typically derived from sugars,white , water-soluble solids that can occur naturally or be produced industrially from sugars.They are used as food sweetener but contain half of the calories of sugar. SYNTHESIS:- Sugar alcohols are produced from sugars by reduction .That means when a sugar reacts with hydrozen,the carbonile radical of the sugar breaks down and sugar alcohols are produced. 3

5. Some common sugar alcohols Erythritol Lactitol Maltitol Isomalt Mannitol Sorbitol Xylitol 5

6. Erythritol :- Erythritol is produced industrially by fermantation.It is 60-70% sweet as sucrose.It is almost noncaloric.It does not affect blood sugar and insulin level.It does not cause tooth decay.It has antibacterial effects against streptococci  bacteria of mouth, reduces dental plaque, and may be protective against tooth decay. Lactitol :- Lactitol is produced from lactose.It is used as a replacement bulk sweetener for low calorie foods with approximately 40% of the sweetness of sugar. It is also used medically as a  laxative.Laxatives are the drugs for constipation. Maltitol :- Maltitol is 75% as sweet as sucrose.It gives a creamy texture of foods.So,it is used in sugar free hard candies,chewing gum,chocolate -flavored desserts,baked foods and ice-cream. 6

7. Isomalt :- Isomalt is 65% as sweet as sucrose.It is a heat- tollerable sugar.Isomalt absorbs a little water.For this reason,it is used in hard candies,toffees,cough removal toffees,lollipop etc. Mannitol :- Mannitol is a common sugar alcohol.It is found naturally in pine- apples,olives,asparagus,sweet potatoes and carrots.It has 70% of sweetness as sucrose.Mannitol has the tendency to cause diarrhoea and bloating. Sorbitol:- Sorbitol is found naturally in fruits and vegetables. It is manufactured from corn syrup. Sorbitol has only 50 percent of the relative sweetness of sugar which means twice as much must be used to deliver a similar amount of sweetness to a product. 7

8. Xylitol:- Xylitol is called "wood sugar" and occurs naturally in straw, corncobs, fruit, vegetables,mushrooms and some cereals. Xylitol has the same relative sweetness as sugar.That means xylitol is 100% sweet as sucrose.It is the mostly used sugar alcohol for diabetic patient.It is found in chewing gums . 8

9. IMPORTANCE OF SUGAR ALCOHOLS Why should WE use sugar alcohols ? You may wonder why manufacturers would put sugar alcohols in foods and other products, or why people might seek them out. Here are a few reasons why consumers choose these products: 9

10. Fewer calories. Sugar alcohols contain fewer calories (0.2 to 3 calories per gram) than sugar (4 calories per gram), making them a diet-friendly choice for people who want to limit their caloric intake, but still enjoy sweet foods. Safe for diabetics. Sugar alcohols are absorbed more slowly (and incompletely) by the body. Unlike regular sugar, they require little or no insulin for metabolism. *People with diabetes should consult their physician, dietitian or other health professional about incorporating sugar alcohols into their daily meal plans. Better dental health. Sugar alcohols do not promote tooth decay since they are not metabolized by the bacteria that produce dental cavities. 10

11. Fewer drug interactions. Sugar alcohols do not react with the pharmacologic ingredients in medicines as much as sugar sometimes can. Individual tastes. The different types of sugar alcohols vary in sweetness, from being about half as sweet to equally sweet as sugar. 11

12. BESIDES, Prebiotic :  Sugar alcohols may feed the friendly bacteria in your gut, having a prebiotic effect like dietary fiber. Bone health:  Many rat studies indicate that xylitol can increase bone volume and mineral content, which should protect against osteoporosis. Skin health:  Collagen is the main structural protein in your skin and connective tissues. Studies in rats demonstrate that xylitol can increase collagen  production. 12

13. In addition:- Sugar alcohols do not lose their sweetness when heated, although many artificial sweeteners do. Sugar alcohols do not absorb water like sugar does. Therefore the surface of foods made with sugar alcohols won't become sticky as quickly as products made with sugar. Molds and bacteria do not grow and multiply on sugar alcohols as well as they do on sugar. 13

14. They can use a combination of sugar alcohols, sugar and/or artificial sweeteners to give the most pleasant taste, appearance, and texture to a food product. 14

15. problems OF SUGAR ALCOHOL Scientists have concluded that sugar alcohols are safe for human consumption. For some people, consuming certain sugar alcohols in excessive amounts may cause gastrointestinal upsets such as gas, bloating and diarrhoea . Problems will depend on your individual sensitivity level and the other foods you consume at the same time avoid them if they cause discomfort. 15

16. Xylitol Is Toxic to Dogs Xylitol is well tolerated by humans but highly toxic to dogs. When dogs eat xylitol, their bodies mistake it for sugar and start producing large amounts of insulin. When insulin goes up, dogs’ cells starts pulling sugar from the bloodstream. This can lead to hypoglycemia (low blood sugar) and can be fatal. If you have a dog, keep xylitol out of reach or refrain from buying it. 16

17. Which Sugar Alcohol Is The Healthiest? Out of all the sugar alcohols, erythritol seems to be one of the best options. It has almost no calories, no effect on blood sugar and causes significantly less digestive problems than the others. It is also good for your teeth and won't end up harming your dog. Plus, it tastes great — it's basically sugar without the calories. 17

18. The Bottom Line Sugar alcohols are popular, low-calorie sweeteners. They are not artificial sweeteners. They are partially resistant to digestion — though certain sugar alcohols, such as maltitol , may cause a slight rise in blood sugar levels. While they are well tolerated, high amounts of some sugar alcohols, such as maltitol , may cause bloating and diarrhea. Erythritol seems to produce the fewest side effects and may be a good choice if you have an intolerance to  sugar alcohols. 18
