Raffinose Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
Raffinose is a white crystalline powder. It is odorless and has a sweet
taste approximately 10% that of sucrose.
Verwenden
D-(+)-Raffinose is an oligosaccharide and trisaccharide whose physical structure and chemical properties have been shown to affect the stability and crystallization of amorphous sucrose, helping to increase the shelf-life of sucrose-containing foods.
Vorbereitung Methode
Raffinose occurs naturally in Australian manna, cottonseed meal,
and seeds of various food legumes. It can be isolated from beet sugar
molasses through sucrose separation, seed-crystallization, and
filtration.
Pharmazeutische Anwendungen
Raffinose is a trisaccharide carbohydrate that is used as a bulking
agent, blood substitute, stabilizing agent, and water scavenger in
freeze-drying where it acts as a stabilizer for freeze-dried formulations. It is also used as a crystallization inhibitor in sucrose
solutions.
Sicherheit(Safety)
Raffinose is a naturally occurring trisaccharide investigated for use
in freeze-dried pharmaceutical formulations. It occurs in a number
of plants that are consumed widely.
Lager
Raffinose is stable under ordinary conditions of use and storage.
Excessive heat should be avoided to prevent degradation. Thermal decomposition products are carbon monoxide and carbon dioxide.
läuterung methode
fructo-furanose [17629-30-0 (5H2O), 512-69-6 (anhydrous)] M 594.5, m 8 0o, 80 -82o, +124o (c 10, H2O), [ ] D +105o (c 1 for pentahydrate, H2O), pK 1 12.40, pK 2 13.44, pK 3 13.52. D(+)-Raffinose crystallises from H2O, 90% aqueous EtOH or MeOH as the pentahydrate. The anhydrous sugar has m 132-135o. It has RF 0.8 on TLC (Silica Gel, and 1:3:3 CHCl3/butanone:/MeOH). The undecaacetate has been purified through an alumina column by elution with CHCl3, and recrystallised from EtOH/MeOH/H2O (3:2:5), with m 99-100o, [] D +92.8o (c 5.14, EtOH).

Inkompatibilitäten
Raffinose is incompatible with strong oxidizers.
Regulatory Status
Raffinose is a naturally occurring trisaccharide and is consumed as
part of a normal diet.
