Fructose is the monosaccharide with the highest chemical activity among sugars, which naturally exists in honey, Jerusalem artichoke, chicory and other compositae plants. Fructose has high sweetness, rich fruit flavor and low calorific value. The metabolic rate in the body is faster than that of glucose, which is easy to be absorbed and utilized by the body and has little effect on blood sugar. Suitable for people with impaired glucose metabolism and liver function to supplement energy. It can promote the growth and reproduction of beneficial bacteria such as Bifidobacterium, inhibit the growth of harmful bacteria, improve gastrointestinal function and metabolism, reduce blood lipid and avoid dental caries. It is an ideal sweetener for diabetics, obese patients and children's food. Functional characteristics: high sweetness, enhanced sweetness. The sweetness is 1.3- 1.8 times that of sucrose, and the osmotic pressure is twice that of sugar. Enhanced flavor, high flavor retention and affinity with protein, enhanced Mallard reaction, high moisture retention, low moisture activity, lowering freezing temperature, chelating metal and detoxifying, and stronger in-vivo alcohol decomposition than glucose. Glycosylated hemoglobin produces three times as much sugar as glucose, and urine patients can use fructose instead of glucose. Application: Beverage: Fructose is often used in healthy drinks to reduce the solid content of sweeteners because of its high sweetness and low heat energy. Fructose mixed with other sweeteners, such as glucose, sucrose, aspartame, etc., has the function of enhancing sweetness, thus reducing the material cost of sweetness. The experiment shows that adding fructose and sucrose in the ratio of 1∶ 1 to the beverage can reduce the dosage of sweetener by 20% compared with using sucrose alone.
Galactose action:
Because it contains calories, it will also be used as a nutritional sweetener. Galactose is one part of lactose molecule, and the other half is glucose. Galactose can be obtained by hydrolysis of lactose under the catalysis of β -lactase Lactose is fermented by Bifidobacterium to produce galactose, which is a component of cerebroside in the cranial nerve system and is closely related to the rapid growth of the brain after the baby is born.
Where does it exist?
Can be found in dairy products or beets. Galactose is a monosaccharide composed of six carbons and one aldehyde, which is divided into aldose and hexose. Both D- galactose and L- galactose are naturally occurring. D- galactose generally exists in milk as a structural part of lactose, and lactose in milk is decomposed into glucose and galactose by human body and absorbed and utilized.
