Browning Behavior of Calcium Maltobionate-water System.

The purpose of the present study was to clarify the browning behavior of calcium maltobionate (CaMb). CaMb samples with varying water content (0-50 %) and water activity (0-0.98) were prepared.

The effect of maltobionic acid on bone metabolism markers in healthy Japanese postmenopausal women: A randomized double-blind placebo-controlled crossover study.

Osteoporosis is characterized by compromised bone strengthpredisposing to an increased risk of fracture and is a disease with a high incidence in postmenopausal women. Frequent estrogen deficiency, particularly in postmenopausal women, induces osteoclast activation and is a major contributor to reduced bone mineral density. Maltobionic acid (MB) reportedly promotes mineral resorption and maintains bone mineral density in human clinical trials, although no studies have confirmed that MB improves bone metabolism in humans.

Metabolic fate of newly developed nondigestible oligosaccharide, maltobionic acid, in rats and humans.

Maltobionic acid (MA), formed by a gluconic acid and glucose linked by an α-1,4 bond, may have the properties of a nondigestible oligosaccharide. The objective of this study was to elucidate the bioavailability of MA in rats and humans by observing digestion of MA by small intestinal enzymes, the fermentation of MA by gut microbiota, and the effect of adaptation following prolonged ingestion of MA. MA digestion was assessed using brush border membrane vesicles (BBMV) from rat small intestine.

Effects of corn syrup solids containing maltobionic acid (maltobionic acid calcium salt) on bone resorption in healthy Japanese adult women: A randomized double-blind placebo-controlled crossover study.

Maltobionic acid is known to have an inhibitory effect on the differentiation of osteoclasts, and it has also been reported in an intervention trial that ingestion of corn syrup solids containing maltobionic acid maintained and increased the bone density of postmenopausal women. However, there is no information on whether maltobionic acid improves bone metabolism in humans. Therefore, we evaluated the influence of corn syrup solids containing maltobionic acid (maltobionic acid calcium salt) on bone resorption markers in healthy Japanese women.

Utilization Characteristics of Maltobionic Acid and Its Effects on Bowel Movements in Healthy Subjects.

We examined the digestibility of maltobionic acid, obtained from enzymatic oxidation of maltose, its utilization by intestinal bacteria, and its biological effects on the bowel movements in healthy subjects. We found that maltobionic acid is not digested by saliva, gastric juice, or pancreatic juice. Moreover, it is digested only to a small extent by small intestinal enzymes.

Maltobionic acid accelerates recovery from iron deficiency-induced anemia in rats.

In experiments 1 and 2, effect of ingestion of maltobionic acid calcium salt (MBCa) on recovery of rats from a latent iron deficiency and from iron deficiency anemia was examined, respectively. After grouping rats into control and iron-deficiency groups, a latent iron deficiency or iron-deficiency anemia was induced in the latter group. And recovery from these states by MBCa containing diets (0%, 3%, and 6% MBCa in diet, classified into MBCa-0, MBCa-3, and MBCa-6 groups) was compared for convalescence period in light of iron sufficient control group.

Effect of Calcium Maltobionate on the Glass Transition Temperature of Model and Hand-made Hard Candies.

Glass transition temperature ( ) is an important parameter for the physical quality control of hard candies. In order to understand the applicability of calcium maltobionate to hard candy, effect of calcium maltobionate addition on the of model and hand-made hard candies was investigated. Freeze-dried calcium maltobionate-sugar (sucrose containing a small amount of glucose-fructose mixture) and calcium maltobionate-reduced isomaltulose mixtures were prepared as model candies, and their anhydrous was evaluated using a differential scanning calorimetry.

Maltobionic acid enhances intestinal absorption of calcium and magnesium in rats.

In Experiment 1, the effects of calcium maltobionate (MBCa) on calcium and magnesium absorption were examined using male rats. Four diets were designed in which 25%, 50%, and 100% of calcium carbonate (CaCO, Control) were substituted with MBCa and were designated as MBCa-25, MBCa-50, and MBCa-100, respectively. The cecal concentration of short-chain fatty acids was significantly higher in groups MBCa-50 and MBCa-100; however, pH of cecal contents did not significantly differ among the groups.

Effect of temperature on gelatinization and retrogradation in high hydrostatic pressure treatment of potato starch-water mixtures.

The effect of temperature (20-70°C) on the gelatinization and retrogradation of potato starch-water mixtures (10-70%, w/w) treated with high hydrostatic pressure (HHP) (400-1000MPa) was investigated. Gelatinization enthalpy change (ΔH) and re-gelatinization enthalpy change of retrograded crystalline part (ΔH) of the HHP-treated starch were evaluated using differential scanning calorimetry. The value of ΔH of 10-20% (w/w) mixtures decreased with increased pressure and temperature, while ΔH of 30-50% (w/w) mixtures decreased to certain values with increased pressure and the values depended on treatment temperature.
