Lactitol

CAS: 585-86-4 Product Description: crystalline lactitol three major forms: lactitol trihydrate, dihydrate, lactitol and lactitol monohydrate. Another kind of commodity is lactitol lactitol solution containing 54%. White crystal or crystalline powder or colorless liquid. Odorless, sweet. About half the calories of sucrose (8.4kJ / g). PH 10% aqueous solution is 4.5 to 7.0. Lactitol trihydrate melting range of 52 ~ 56 ℃, lactitol dihydrate melting range of 70 ~ 80 ℃, monohydrate thereof is 115 ~ 125 ℃. Easily soluble in water, but almost no moisture absorption, it is one of the smallest hygroscopic sugar alcohol. Light, heat stable, lose crystal water heated to 100 ℃, intramolecular dehydration to produce milk caramel and low molecular decomposition occurs to 250 ℃. Remained stable at pH3 ~ 9,100 ℃, do not break down, do not change color. But it may be a strong acid, strong base decomposition. Physiological functions: 1. suppressing rise in blood sugar. Lactitol does not stimulate insulin secretion and therefore do not lead to increased blood glucose levels (see Figure 03106-1). 2. The anti-caries resistance. Lactitol can not be made in the oral cavity microbes produce alcohol acid, and such acids can damage tooth enamel through deionization, dental caries. Changes in pH in the oral cavity and 10% sucrose comparison of Figure 03106-2. Lactitol British Dental Association and health education institutions unanimously recommended the latest anti-caries sweeteners approved for use by the British Scientific Committee on Food. 3. inhibition and accumulation of excess body fat. On the one hand is a low-calorie sugar lactitol alcohol, and because it does not stimulate insulin secretion and therefore does not thereby activating adipose tissue lipoprotein lipase (LPL), and therefore, when the same food with fat, inhibit fat in the body which led to the accumulation of excess. The regulation of intestinal flora and pH. Lactitol can intestinal bifidobacteria proliferation of 10 to 100 times. Lactitol itself is very stable, after taking non-digestible and absorption in the gastrointestinal tract into the large intestine, especially in the distal colon section, easily microbes decompose. Such microorganisms Bifidobacterium, Lactobacillus, Bacteroides, digestive bacteria and fungi. Among the more prominent bifidobacteria, it can promote the decomposition of lactitol and use itself has been nutrition and reproduction. Other microbes, such as anaerobic streptococci, lactobacilli, also have a similar situation. At this time of the beneficial bacteria it prevailed, inhibiting other pathogens such as Staphylococcus aureus, Proteus, Pseudomonas aeruginosa survival. As well as the large population of beneficial bacteria Bifidobacterium, and human interdependence, interaction, mutual restraint between each other, to maintain the normal balance of bacteria in the human gut to form symbiotic parasites in the intestinal tract, forming a natural defense to to resist the invasion of foreign bacteria. These microbes can promote intestinal synthesis of vitamin and amino acids and other substances, improve gastrointestinal function, help digestion and absorption, activate strengthen immune function, anti-aging. Further, lactitol fermentation by the intestinal flora, decomposition, oxidation, formation of acetic acid, propionic acid, butyric acid, lactic acid and carbon dioxide, hydrogen, etc. can reduce the intestinal pH values, and the ammonia formed is difficult to be absorbed in the intestinal wall ammonium excreted with the feces. The acidic environment of the intestines, can promote the absorption of calcium, but also make the body of harmful, toxic substances, such as urea nitrogen, monoamine substances, toxic nitrosamines, carcinogens, etc. excreted. Method: from skim dairy lactose was then pressurized nickel catalytic hydrogenation (100 ℃, 30% ~ 40% lactose solution, 4MPa) after filtration, ion-exchange resins and activated carbon purification concentrated at different temperatures and crystallized concentration.
