Isomaltulose Powder

What is Isomaltulose powder?

Isomaltulose Powder, also known as palatinose, is an isomer of sucrose. It exists in small amounts in honey, sugar cane juice and other substances. It can selectively promote the growth of bifidobacteria in the human intestine. It has low calorie and anti-caries properties. , inhibit obesity and other functional properties. The molecular formula of isomaltulose is C12H12O11·H2O, with a molecular mass of 360.32. It is a reducing disaccharide formed by connecting glucose and fructose with α-1,6 glycosidic bonds. As a crystalline disaccharide, it contains 1moL crystal Water, and does not form crystals after losing crystal water. Its structural formula is shown in the figure below.

The appearance and taste of isomaltulose are similar to sucrose, with white crystals. The sweetness is about 42% of sucrose and does not change with environmental changes. The solubility is only 50% of sucrose at room temperature. When the temperature rises, the solubility increases sharply, reaching 85% of sucrose at 80°C. Compared with the melting point of sucrose (160~185 ℃), the melting point of isomaltulose is lower (123~124 ℃).

Isomaltulose powder sweetener also has high stability. Its main performance is: (1) It has good acid hydrolysis resistance. At pH 2.0, 20% isomaltulose solution will not undergo hydrolysis reaction after boiling for 1 hour. Therefore, it is suitable for use in acidic foods. is more stable than sucrose; (2) isomaltulose added to isotonic or hypotonic beverages can maintain the stability of osmotic pressure; (3) isomaltulose is resistant to most bacteria and yeast and is not easily utilized. Therefore, products added with isomaltulose are easier to maintain sweetness.

The use of isomaltulose in sports foods and fat-reducing meal replacement foods

1. Energy supplement suitable for long-term exercise

After isomaltulose enters the human body, it is hydrolyzed in the small intestine by the sucrase-isomaltase complex into one molecule of glucose and one molecule of fructose, which are the same as sucrose, providing liver glycogen and muscle glycogen for exercising people. The decomposition speed of isomaltulose is one-fifth that of sucrose, and all isomaltulose can be digested, absorbed and converted into energy in the body, and the glucose and fructose produced will steadily supply energy to the body for 6 hours. , perfect for pairing with fast-absorbing sugar and used at any time before or after exercise.

2. Maintain glucose and insulin concentrations during exercise and avoid hypoglycemia during exercise

After ingesting isomaltulose, it can keep the glucose and insulin in the blood stable within a certain concentration range for a long time. The reason is that it is digested and absorbed slowly in the body. Normally, when the human body ingests rapidly absorbed sugars, such as glucose, the rapid rise in blood sugar will stimulate insulin secretion to accelerate or even over-secret, leading to hypoglycemia to replenish energy during exercise and reduce exercise capacity. Therefore, the application of isomaltulose to supplement carbohydrate energy during exercise can stabilize blood sugar levels and maintain long-lasting exercise ability.

3. Increase fat utilization and promote fat burning

Normally, people need to replenish calories and water after exercise, but when they ingest foods that use isomaltulose as energy and sweet substances, the concentration of beneficial fatty acids in the blood will not decrease. During long-term exercise, body fat is broken down as energy, and the levels of beneficial fatty acids in the blood continue to increase and are continuously consumed and utilized, promoting the continuous consumption of fat. After exercise, if fast carbohydrates, such as glucose, are ingested, the level of glucose in the blood will continue to increase, and the decomposition of fat into free fatty acids for energy will gradually decrease. However, after using isomaltulose as carbohydrate for energy, because of its slow The digestion and absorption process will continue to promote fat decomposition and energy supply, achieving the effect of long-term fat decomposition and utilization.

As a source of carbohydrate energy supply and energy control for meal replacement products, the slow digestion and absorption characteristics of isomaltulose can also promote the decomposition and utilization of fat in the body and achieve the effect of fat loss.

4. Stay focused

Rapid increases or decreases in blood sugar and insulin concentrations will affect the body's functions and mental stability. After ingesting isomaltulose, the blood sugar level and insulin concentration are increased by 10%-20% compared with fasting, and this state can be maintained for a long time. In this way, a certain concentration of energy source can be provided to the brain for a long time, maintaining The brain is full of energy, stabilizing the body's functions and mental state.

Applications of isomaltulose

Isomaltulose Powder has similar physical and chemical properties to sucrose. It is used in products such as cream instead of sucrose and has similar viscosity and fluid characteristics to sucrose. Isomaltulose has a pure sweet taste, can mask odor, balance the taste, and improve the flavor of food. It provides convenience for the development of functional foods with good taste and good taste using natural and healthy raw materials. At the same time, it slowly releases energy and does not cause blood sugar to rise. The health effects of preventing dental caries and improving brain function make it widely used in food for specific groups of people.

1. Application in dairy products

Isomaltulose powder sweetener has been widely used in dairy products at home and abroad. The application of isomaltulose in dairy products can mask the odor and give dairy products certain health effects, which provides help for the development of dairy foods for children and middle-aged and elderly people. . For example, Serita launches active yogurt, which uses isomaltulose and sucralose as sweeteners. South Korea's Maeil functional black sesame soy milk also adds isomaltulose to cover up the bad flavor of soy milk.

2. Application in baked goods

GB2760-2014 stipulates that the limit requirement for isomaltulose used in baked goods such as bread, pastries, and biscuits is to add an appropriate amount as needed. Domestic companies have added isomaltulose to biscuits, hand-shredded bread and other products. Isomaltulose can be used in baked goods to improve product taste and storage stability. Since isomaltulose is almost non-hygroscopic, it is used in Waffles can significantly improve the structure of the product.

3. Application in confectionery and chocolate

Isomaltulose powder sweetener has excellent properties such as stable physical and chemical properties, low hygroscopicity, and ease of refining and grinding, which makes its application in confectionery and chocolate very advantageous. Used in hard candies to prevent the candies from sticking together and making the candies less likely to deform. Isomaltulose hard candies have a high glass transition temperature and high temperature stability, making them ideal even in areas with hot flash climates; Coating raw materials can be used to prepare soft candies, chocolate beans, pralines, and gel-type products. The low processing temperature of isomaltulose (45°C ~ 55°C) can successfully complete the coating of heat-sensitive core materials; isomaltulone Sugar has a taste comparable to sucrose and is not affected by the cold effect. It is used in chocolate to make the sweetness natural, and can be combined with fat substitutes and fillers to give chocolate stable flow properties.

4. Used in food development for specific groups of people

The low GI value (insulin index) of isomaltulose provides the basis for its use in food for diabetics. The use of isomaltulose to develop sports foods is also very common abroad. For example, Sports Yo-Kan produced by Japan's Imuraya is a ready-to-eat energy supplement yokan (red bean cake) that can easily replenish energy and contains palatinose. TM (isomaltulose) and maltodextrin are foods that continuously provide energy. Belgium's 3 Action sports nutrition series products use isomaltulose as the main raw material, which can provide long-lasting energy and power.

Isomaltulose is used to inhibit fat accumulation and accelerate fat oxidation. By using isomaltulose as one of the raw materials, and combining it with other healthy ingredients, products with slimming effects can be developed, while having low GI and low GL (glycemic load). ) diet helps maintain weight after losing weight.

Isomaltulose is suitable for people who eat it

1. Suitable for diabetic patients

The cumulative increase in blood sugar levels in the body after ingesting isomaltulose is much lower than that of sugar, and the changes in blood insulin and blood sugar levels are balanced, indicating that isomaltulose is absorbed much slower than sucrose, so it can be consumed by diabetic patients.

2. Non-cariogenic, especially suitable for children

Dental caries occurs because the tartar attached to the tooth surface contains many bacteria. When there is a lot of sugar, the bacteria in the tartar, such as Streptococcus mutans, ferment sucrose and produce acid, which dissolves calcium and causes decay. In addition, Streptococcus mutans can also Sucrose is synthesized into insoluble and highly adhesive dextran, which can adhere to teeth and produce tartar. Isomaltulose cannot be used by the microorganisms that cause tooth decay in the mouth, and of course it will not produce insoluble glucan. Therefore, plaque will not form. Causes tooth decay and causes periodontal disease problems. So cavities won’t form. Therefore, isomaltulose not only does not cause tooth decay itself, but also inhibits tooth decay caused by sucrose.

3. Suitable for people with high blood pressure, hyperlipidemia, obesity and those who are afraid of obesity.

Low in calories, isomaltulose can be digested and absorbed like sucrose. Its caloric value is about 4Kacl/g. It is more suitable for people with high blood pressure, hyperlipidemia, obesity and people who are afraid of obesity.

4. Suitable for athletes

Slow hydrolysis and absorption speed, more suitable for athletes. In order to maintain endurance and reduce fatigue, athletes need to supplement long-term energy. After isomaltulose enters the human body, it can be hydrolyzed in the small intestine by the carbohydrase-isomaltase complex into glucose and fructose, which are the same decomposition products of sucrose, and can then be digested and absorbed. Since its hydrolysis speed is one-fifth that of sucrose, It can be inferred that the absorption rate of isomaltulose is much slower than that of sucrose. In addition, isomaltulose can be completely digested and absorbed and converted into energy, so it is particularly suitable for providing energy for long-term sports.

5. Suitable for the general public - intestinal probiotic function

Isomaltulose is an excellent bifidobacteria proliferation factor. Although isomaltulose cannot be used by the enzyme system of the human body and most microorganisms, it can be decomposed and utilized by bifidobacteria in the human intestine, promoting The growth and reproduction of Bifidobacterium maintains the microecological balance of the intestines and is beneficial to human health, so isomaltulose is also suitable for the general public.
