Overview | in recent years, with the improvement of people's living standards, the enhancement of health care awareness and the progress of the concept of consumption, so that people's requirements for sweeteners also pay more attention to the unity of health care and nutrition. Sucrose-natural nutritive sweetener, although it is essential for human life activities and physiological metabolism of substances, improper eating will produce some modern diseases. Therefore, the development of new natural sweeteners that can replace sucrose has become one of the important topics today. palatinose is an isomer of sucrose, which is converted and refined by α-glucosyltransferase using sucrose as raw material. It is the application of biotechnology-enzyme engineering to change the nature of sucrose sweeteners, is a natural nutritional sugar, can avoid the shortcomings of sucrose and disease. Paraginose, commonly known as Isomaltulose, is a disaccharide in which glucose and fructose are combined with α-1,6. Glucose in sucrose is separated from the original α-1,2 binding portion of fructose by the action of Glucosyltransferase and converted into α-1,6 binding. It differs from sucrose only at the site of the linkage of glucose and fructose in the molecule, so it is an isomer of sucrose. It is white crystals, no smell, molecular weight of 360.32, containing one mole of crystal water, Melting point 124 ℃, specific optical rotation [α][20]0 is 97.2, non-hygroscopic or very low, low solubility and viscosity than sucrose, acid hydrolysis. At present, the method of immobilized cells (enzyme) of biotechnology is used to convert sucrose into paraginose. |
Application | Because of the following properties of Palatine sugar: low sweetness, non-hygroscopic, resistant to acidolysis, yeast and some microorganisms can not be used, do not cause dental caries, diabetes can be consumed, flavor similar to sucrose and so on. Therefore, where the use of sucrose as a sweetener food, beverages, frozen food, etc. can be partially or fully replaced by paragin sugar, mainly used for cold drinks, cakes, fruit juice concentrate, candy, jam, wine, biscuits, bread, etc. Parkinson's sugar in the small intestine can be a complex enzyme gradually broken down into glucose and fructose, slowly absorbed into the metabolism, and can make blood sugar stable at a certain level, due to slow absorption, insulin levels do not change much, diabetes is edible, is a suitable for growth and development need sugar in infants and adolescents to eat non-caries sweeteners. The Japanese food review standard for paraginose J.S.D stipulates that paraginose can be used to replace or partially replace sucrose as a sweetener for food and beverage to make a non-caries sweet food. The Japanese Nutrition Food Association also provides that where more than 70% of Paraben is used in food, it can be indicated that the food is a food that does not produce dental caries. Parabens will be widely used in the 21st century bio-engineering high-tech products. When mankind enters the new century, this new functional sweetener will become a widely used food ingredient, so that people enjoy sweet food. |
