Maltotetraose syrup

The intestinal tolerance of cyclotetraglucose syrup was examined in a group of 40 healthy, predominantly male human volunteers (28 males and 12 females) in a double-blind crossover study. Subjects were provided the test product at dose levels of 25, 40, 55 or 70 g (dry matter basis) (the time between each treatment was not reported). A readily digestible, maltotetraose syrup was administered as a negative control. One female subject dropped out prior to completing the... 

From these new enzymes, the exo-maltotrio-hydro-lase as well as exo-maltotetrao-hydrolase are commercially available in Japan for production of high maltotriose- and high-maltotetraose-syrups, from which the pure malto-oligosaccharides can be made by chromatographic enrichment and crystallization. 

Maltotetraose syrups are reported to have an inhibitory effect on putrefactive bacteria, such as Clostridium perfringens and Enterobacter spp. and to lead to an improvement of human colonic conditions. 

Maltodextrins are products of hydrolysis with a DE value of <20. They generally contain from 0.3 to 1.6% of glucose, 0.9 to 5.8% of maltose, 1.4 to 11.0% of maltotriose, 1.4 to 6.1% of maltotetraose and 75.5 to 96.0% of higher sugars. Hydrolysates containing maltodextrins are mostly dried or, exceptionally, prepared as syrups. They increase the viscosity, smoothness and surface... 

Commercially available enriched syrups are those from maltotriose, maltotetraose and maltohexaose. They are used in the production of diagnostic materials for testing amylase enzyme patterns as well as for their antiputritive activity in the human intestine as components in nutritive and dietetical formulations. Future industrial significance in nonfood applications may result from their moisture-equilibrating and - retrogradation-retarding properties. 

The different types of syrups are enriched with respect to one of the linear oligosaccharides maltotriose, maltotetraose, maltopentaose, maltohexaose [C H,o05] (n = 3,4, 5, 6).
