“Polyols: a Primer for Dietetic Professionals” Is a Self-Study
1 “Polyols: A primer for dietetic professionals” is a self-study module produced by the Calorie Control Council, an accredited provider of continuing professional education (CPE) for dietetic professionals by the Commission on Dietetic Registration. It provides one hour of level 1 CPE credit for dietetic professionals. The full text of the module is in the notes section of each page, and is accompanied by summary points and/or visuals in the box at the top of the page. Directions for obtaining CPE are provided at the end of the module. 2 After completing this module, dietetic professionals will be able to: • Define polyols. • Identify the various types of polyols found in foods. • Understand the uses and health effects of polyols in foods. • Counsel clients on how to incorporate polyols into an overall healthful eating pattern. 3 4 Polyols are carbohydrates that are hydrogenated, meaning that a hydroxyl group replaces the aldehyde or ketone group found on sugars. Hydrogenated monosaccharides include erythritol, xylitol, sorbitol, and mannitol. Hydrogenated disaccharides include lactitol, isomalt, and maltitol. And hydrogenated starch hydrolysates (HSH), or polyglycitols (a wide range of corn syrups and maltodextrins), are formed from polysaccharides (Grabitske and Slavin 2008). 5 Nearly 54 percent of Americans are trying to lose weight, more than ever before. Increasingly, they are turning toward no- and low-sugar, and reduced calorie, foods and beverages to help them achieve their weight loss goals (78% of Americans who are trying to lose weight) (CCC 2010). Polyols, found in many of these foods, are becoming a subject of more interest. 6 They are incompletely digested , therefore are sometimes referred to as “low- digestible carbohydrates.” Polyols are not calorie free, as there is some degree of digestion and absorption of the carbohydrate. -

For this purpose, two novel polyols from the aforementioned oils were obtained in a one-single step reaction using a mixture of hydrogen peroxide and acetic acid. The polyol derivatives obtained from the two studied oils were characterized by spectral (FTIR, 1H NMR, and 13C NMR), physicochemical (e.g., chromatographic analysis, acid value, oxidizability values, iodine value, peroxide value, saponification number, kinematic viscosity, density, theorical molecular weight, hydroxyl number, and hydroxyl functionality) and thermal (TGA) analyses according to standard methods. -

Chemical curve: R.I. for MDI at Ref. Temp. of 25˚C Application The most commonly used isocyanates for the production of PU are methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI). If color and transparency are important, an aliphatic diisocyanate such as hexamethylene diisocyanate (HDI) is used. The first step in the production of polyurethane is the synthesis of the raw materials. The diisocyanate is typically produced from basic raw materials via nitration, hydrogenation and phosgenation. The feedstock and initial processing steps depend on the Introduction desired isocyanate, but all go through a phosgenation step. Polyurethanes (PUs) are a class of versatile materials with great potential for use in different applications. For instance, for the production of MDI, benzene and They are used in the manufacture of many different nitric acid are reacted to produce nitrobenzene. After items, such as paints, liquid coatings, elastomers, a hydrogeneration step, the nitrobenzene is converted insulators, elastics, foams and integral skins. to aniline.

Polyol Case Study
Polyol Case Study Case Study: Polyol Chewing Gums – A Systematic Review of the International Literature The effect of polyol containing chewing gums was evaluated in a systematic review published in 2008, in the Journal of the American Dental Association. 1 Eligible studies were retrieved from Medline, Google Scholar and the Cochrane Library and were published mainly from 1980-2001. Comparative studies were included, if they were published in English, in peer reviewed journals, including the evaluated effect of chewing gums containing at least one polyol (xylitol, sorbitol, mannitol or maltitol) on caries development. Data were extracted by two researchers on clinical and radiographic outcomes from original papers with a priority given to clinical outcomes. The quality of the studies was assessed using the Jadad scale. 2 The dose of the polyol was combined with the duration of use to produce a variable called poyol load. Preventive fractions were calculated with the following formula: PF= (XC − XE)/XC XC is the mean caries increment in the control group and XE is the mean caries increment in the group with the polyol-containing chewing gum. There were four groups of studies; 1) xylitol vs. no chewing gum; 2) xylitol and sorbitol vs. no chewing gum; 3) sorbitol vs. no chewing gum and; 4) sorbitol and mannitol vs. no chewing gum. www.allianceforacavityfreefuture.org | PAGE 1/3 The original literature search produced 231 articles with 19 deemed appropriate and meeting the study inclusion criteria for the meta-analysis. The studies included school children in the United States, Canada, Finland, Denmark as well as other European countries. -

Sweet Sensations by Judie Bizzozero | Senior Editor
[Confections] July 2015 Sweet Sensations By Judie Bizzozero | Senior Editor By R.J. Foster, Contributing Editor For many, terms like “reduced-sugar” or “sugar-free” do not go with the word “candy.” And yet, the confectionery industry is facing growing demand for treats that offer the taste people have grown to love without the adverse health effects they’re looking to avoid. Thankfully, there is a growing palette of ingredients from which candy makers can paint a new picture of sweetness that will be appreciated by the even most discerning of confectionery critics. SUGAR ALCOHOLS Also referred to as polyols, sugar alcohols are a common ingredient in reduced-sugar and sugar-free applications, especially confections. Funny thing, they’re not sugars or alcohols. Carbohydrate chains composed of monomeric, dimeric and polymeric units, polyols resemble both sugars and alcohols, but do not contain an ethanol molecule. All but two sugar alcohols are less sweet than sugar. Being only partially digestible, though, replacing a portion of a formulation’s sugar with a sugar alcohol reduces total calories without losing bulk (which can occur when replacing sugar with high-intensity sweeteners). Unique flavoring, texturizing and moisture-controlling effects also make polyols well-suited for confectionery products. Two very common and very similar monomeric polyols are sorbitol and mannitol. Present in a variety of fruits and vegetables, both are derived from products of cornstarch hydrolysis. Sorbitol is made via hydrogenation of glucose, which is why sorbitol is sometimes referred to as glucitol. Mannitol is created when fructose hydrogenation converts fructose into mannose, for which the final product, mannitol, is named. -

Sugar Alcohols a Sugar Alcohol Is a Kind of Alcohol Prepared from Sugars
Sweeteners, Good, Bad, or Something even Worse. (Part 8) These are Low calorie sweeteners - not non-calorie sweeteners Sugar Alcohols A sugar alcohol is a kind of alcohol prepared from sugars. These organic compounds are a class of polyols, also called polyhydric alcohol, polyalcohol, or glycitol. They are white, water-soluble solids that occur naturally and are used widely in the food industry as thickeners and sweeteners. In commercial foodstuffs, sugar alcohols are commonly used in place of table sugar (sucrose), often in combination with high intensity artificial sweeteners to counter the low sweetness of the sugar alcohols. Unlike sugars, sugar alcohols do not contribute to the formation of tooth cavities. Common Sugar Alcohols Arabitol, Erythritol, Ethylene glycol, Fucitol, Galactitol, Glycerol, Hydrogenated Starch – Hydrolysate (HSH), Iditol, Inositol, Isomalt, Lactitol, Maltitol, Maltotetraitol, Maltotriitol, Mannitol, Methanol, Polyglycitol, Polydextrose, Ribitol, Sorbitol, Threitol, Volemitol, Xylitol, Of these, xylitol is perhaps the most popular due to its similarity to sucrose in visual appearance and sweetness. Sugar alcohols do not contribute to tooth decay. However, consumption of sugar alcohols does affect blood sugar levels, although less than that of "regular" sugar (sucrose). Sugar alcohols may also cause bloating and diarrhea when consumed in excessive amounts. Erythritol Also labeled as: Sugar alcohol Zerose ZSweet Erythritol is a sugar alcohol (or polyol) that has been approved for use as a food additive in the United States and throughout much of the world. It was discovered in 1848 by British chemist John Stenhouse. It occurs naturally in some fruits and fermented foods. At the industrial level, it is produced from glucose by fermentation with a yeast, Moniliella pollinis. -
Effects of Polyols on the Quality Characteristics of Sucrose-Free Milk
RSC Advances PAPER View Article Online View Journal | View Issue Effects of polyols on the quality characteristics of sucrose-free milk chocolate produced in a ball mill Cite this: RSC Adv.,2019,9, 29676 Aziz Homayouni Rad,ab Haniyeh Rasouli Pirouzian, *a Nevzat Konar,c Omer Said Tokerd and Derya Genc Polate Sucrose-free milk chocolates containing different types of bulk (isomalt, xylitol and maltitol) and high intensity (Stevia) sweeteners were produced by using a ball mill. The main quality characteristics of the formulated chocolates were evaluated and compared with those of the conventional sample containing sucrose. The Casson model was the best fitting model for the rheological data. Casson viscosity and Casson yield stress were significantly affected by the type of bulking agent in chocolates formulated with xylitol (p < 0.05). However xylitol notably improved the overall acceptability according to the sensory analysis results. Chocolates containing the sucrose replacers demonstrated lower Tonset values and higher enthalpy than the control sample. Sucrose-free chocolates illustrated a higher degree of particle agglomeration. Bulk sweeteners meanwhile seem to have high potential for milk chocolate production Creative Commons Attribution-NonCommercial 3.0 Unported Licence. with low calorie values by using the ball mill technique. Industrial applications: the production of sucrose-free chocolates with conventional methods requires a lot of time and energy. Recently, using alternative methods for chocolate production has been raising interest in many small industries. This study proposed a ball mill method for the preparation of sucrose-free milk chocolates with physiochemical properties almost ranging in the standard limit defined for chocolate. -
Sugar Alcohols: a Review
International Journal of PharmTech Research CODEN (USA): IJPRIF, ISSN: 0974-4304, ISSN(Online): 2455-9563 Vol.9, No.7, pp 407-413, 2016 Sugar alcohols: A review Ramezan Ali Mahian1, Vahid Hakimzadeh2* 1,2Department of Food Science and Technology, Quchan Branch, Islamic Azad University, Quchan, Iran Abstract : Sugar alcohols are extensively used as sweetening agents. They sometimes possess advantages over the parent sugars in sweetness, caloric reduction and non-cariogenicity. The physical status of carbohydrates in food and confectionery affects both the properties of the product during production and the quality of the final product. Sugar alcohols, such as xylitol, mannitol, sorbitol, and erythritol are emerging food ingredients that provide similar or better sweetness/sensory properties of sucrose, but are less calorigenic. Also, sugar alcohols can be converted into commodity chemicals through chemical catalysis. Biotechnological production offers the safe and sustainable supply of sugar alcohols from renewable biomass. These compounds are usually produced by a catalytic hydrogenation of carbohydrates, but they can be also found in nature in fruits, vegetables or mushrooms as well as in human organism. Due to their properties, sugar alcohols are widely used in food, beverage, confectionery and pharmaceutical industries throughout the world. They have found use as bulk sweeteners that promote dental health and exert prebiotic effect. They are added to foods as alternative sweeteners what might be helpful in the control of calories intake. Consumption of low-calorie foods by the worldwide population has dramatically increased, as well as health concerns associated with the consequent high intake of sweeteners. Key words: Sugar alcohols, low-calorie, Sugar-free products, sweetener. -
Effects of Sugars and Sugar Alcohols on the Gelatinization Temperatures of Wheat, Potato, and Corn Starches
foods Article Effects of Sugars and Sugar Alcohols on the Gelatinization Temperatures of Wheat, Potato, and Corn Starches Matthew C. Allan, MaryClaire Chamberlain and Lisa J. Mauer * Department of Food Science, Purdue University, 745 Agriculture Mall Drive, West Lafayette, IN 47907, USA; [email protected] (M.C.A.); [email protected] (M.C.) * Correspondence: [email protected]; Tel.: +1-(765)-494-9111 Received: 13 May 2020; Accepted: 3 June 2020; Published: 8 June 2020 Abstract: The gelatinization temperature (Tgel) of starch increases in the presence of sweeteners due to sweetener-starch intermolecular interactions in the amorphous regions of starch. Different starch botanical sources contain different starch architectures, which may alter sweetener-starch interactions and the effects of sweeteners on Tgels. To document these effects, the Tgels of wheat, potato, waxy corn, dent corn, and 50% and 70% high amylose corn starches were determined in the presence of eleven different sweeteners and varying sweetener concentrations. Tgels of 2:1 sweetener solution:starch slurries were measured using differential scanning calorimetry. The extent of Tgel elevation was affected by both starch and sweetener type. Tgels of wheat and dent corn starches increased the most, while Tgels of high amylose corn starches were the least affected. Fructose increased Tgels the least, and isomalt and isomaltulose increased Tgels the most. Overall, starch Tgels increased more with increasing sweetener concentration, molar volume, molecular weight, and number of equatorial and exocyclic hydroxyl groups. Starches containing more short amylopectin chains, fewer amylopectin chains that span through multiple clusters, higher number of building blocks per cluster, and shorter inter-block chain lengths exhibited the largest Tgel increases in sweetener solutions, attributed to less stable crystalline regions.
