Raffinose, also known as D(+)-Raffinose pentahydrate (CAS 512-69-6), is a naturally occurring trisaccharide composed of galactose, glucose, and fructose . It is commonly found in a variety of plants, including legumes, broccoli, and spinach, as well as in cottonseeds and some types of milk . Raffinose is known for its prebiotic properties, as it promotes the growth of beneficial bacteria in the gut, which can contribute to better digestive health and immune function .
This sugar is also recognized for its potential health benefits, such as its use as a natural sweetener and its role in stabilizing and preserving food products . Raffinose is used as a food additive and is considered safe for human consumption within the limits set by food safety authorities .
In terms of its physical properties, raffinose is a white, crystalline powder that is soluble in water . It has a melting point of 84-85°C and remains stable at room temperature . The compound is non-reducing, meaning it does not react with Fehling's solution, which is used to test for the presence of reducing sugars .
Raffinose can be synthesized from sucrose using the enzyme α-galactosidase, which cleaves the α(1→6) linkage between the galactose and glucose molecules, producing raffinose and free glucose . Various analytical techniques, such as high-performance liquid chromatography (HPLC), infrared spectroscopy (IR), nuclear magnetic resonance (NMR) spectroscopy, and mass spectrometry (MS), can be used to characterize raffinose .
In the food industry, raffinose is used to add sweetness and as a stabilizing agent . It is also used in the production of certain vaccines and pharmaceuticals due to its cryoprotective properties, which help preserve cells and tissues during freezing and thawing processes
