meso-Erythritol (CAS: 149-32-6) is a natural constituent of several foods and beverages in levels sometimes exceeding 1 g/kg. Depending on the concentration used, erythritol is approximately 60 % as sweet as sucrose. It is noncariogenic and not metabolized in the human body which means that it is more or less calorie-free. In the European Union, erythritol is approved as E 968 for a large number of food applications. It is GRAS in the United States and also approved in many other countries.
meso-Erythritol is a sugar alcohol (polyol). The sweetness of erythritol is low, the sweetness of erythritol is only 60%-70% of sucrose, the entrance has a cool taste, the taste is pure, and there is no post-bitterness. It can be used in combination with high-intensity sweeteners to inhibit its Undesirable flavors of high-intensity sweeteners. Erythritol has high stability, is very stable to acid and heat, and has high acid and alkali resistance. It will not decompose and change at temperatures below 200℃, and will not undergo Maillard reaction to cause discoloration. The heat of dissolution of erythritol is high: erythritol has an endothermic effect when dissolved in water, and the heat of dissolution is only 97.4kJ/kg, which is higher than the endothermic degree of glucose and sorbitol, and has a cooling feeling when eating. The solubility of erythritol at 25℃ is 37% (W/W). With the increase of temperature, the solubility of erythritol increases, and it is easy to crystallize and separate out crystals. Erythritol is very easy to crystallize, but it will not absorb moisture in a 90% humidity environment. It is easy to be crushed to obtain a powdery product, which can be used on the surface of food to prevent food from absorbing moisture and deteriorating.
meso-Erythritol, belonging to the class of sugar alcohols, is identified in a variety of food products, fruits, vegetables, beverages and dietary supplements. It is known as a low glycemic food additive and plays an important role as a sweetener for diabetic patients, since it does not have glycemic or insulinemic effect due to its ability to not get metabolized but get absorbed in the small intestine. It is also reportedly used as a sugar substitute in toothpaste, chewing gums, confectionery food products, etc.
Application field
1. Drinks In recent years, erythritol has been used in the development of new zero-calorie and low-calorie beverages. Erythritol can increase the sweetness, body and smoothness of drinks, while reducing bitterness, and can also mask other odors and enhance the flavor of drinks. Erythritol can also be used in refreshing solid drinks, because erythritol absorbs a lot of heat when it dissolves.
2. Baked goods
Erythritol is a proven ingredient for higher quality functional or low-calorie bakery products. It can not only replace sucrose physically and chemically but also bring health benefits, and baked products using erythritol have better structural compactness and softness than products that also use sucrose as raw materials, And it has different melt-in-the-mouth and subtle color differences. The erythritol used in baked goods should preferably be powdered or crystallized with a fine particle size (<200μm), and the fine particles will bring a smooth and round taste to the product.
3. Additives
Erythritol can also be used to produce good quality bakery product additions such as jams, cream, butter icing and some surface decorations.
A. Adding erythritol to jam can enhance the natural fruity index.
B. Adding erythritol to cream icing (full fat) will not only reduce calories but also bring a refreshing taste; when the product uses erythritol, maltitol liquid and aspartame at the same time, the energy value can be reduced by nearly 50%.
4. Candies
The current candy and chocolate market has also extended from the early use of sucrose as the basic raw material to the new low-sugar and low-calorie sugar-based products. In recent years, functional sugar products have been hyped in full swing in the market and have become the current international The consumption hotspot and development focus of the candy market, the market potential is huge. After long-term practical research, it has been proved that the new functional raw material erythritol fully meets the requirements. The taste of erythritol is the same as that of sucrose, and there is no need to add strong sweeteners such as aspartame or saccharin. The resulting candies are cooler and cooler than other "non-sucrose" candies, with pure sweetness and no unpleasant aftertaste
5. Chocolate
Erythritol can easily replace sucrose in the product and reduce the energy of chocolate by 34%. No other sugar alcohol can provide such energy reduction, and endow the product with a cool taste and non-cariogenic properties. Due to its low hygroscopicity, erythritol helps to overcome the blooming phenomenon of other sugars when making chocolate.
6. Pharmaceutical industry
The properties of erythritol, such as anti-caries, anti-oxidation, moisture retention and non-flammability, make its application in the fields of medicine and daily chemicals continue to expand.
meso-Erythritol is a naturally occurring noncariogenic excipient used in a variety of pharmaceutical preparations, including in solid dosage forms as a tablet filler, and in coatings. It has also been investigated for use in dry powder inhalers.It is also used in sugar-free lozenges,and medicated chewing gum. meso-Erythritol can also be used as a diluent in wet granulation in combination with moisture-sensitive drugs. In buccal applications, such as medicated chewing gums, it is used because of its high negative heat of solution which provides a strong cooling effect. meso-Erythritol is also used as a noncaloric sweetener in syrups; it is used to provide sensorial profile-modifying properties with intense sweeteners; and it is also used to mask unwanted aftertastes. meso-Erythritol is also used as a noncariogenic sweetener in toothpastes and mouthwash solutions.
DEFINITION
Erythritol is obtained by fermentation of starch enzyme hydrolysate (from starches such as wheat and corn). It is obtained from the fermentation broth of suitable osmophilic yeasts such as Moniliella pollinis or Trichosporonoides megachiliensis. It contains NLT 96.0% and NMT 102.0% of Erythritol (C4H10O4), calculated on the anhydrous basis.
