Raffinose Powder Melitriose Powder

Raffinose Powder & Melitriose Powder

Raffinose Powder and Melitriose Powder are two different types of sugar powders, each with a unique chemical structure and properties. Here is a brief introduction to the two sugar powders:

Raffinose Powder

Raffinose is a trisaccharide made of galactose, glucose and fructose connected by glycosidic bonds. It is widely found in the plant kingdom, especially in legumes such as soybeans, beets and certain grains. Raffinose has the characteristics of low sweetness, low caloric value and poor digestion and absorption by the human body due to its special structure, so it is often used as a food additive, especially in low-sugar and sugar-free foods. In addition, raffinose also has the functions of promoting intestinal health and improving constipation because it can promote the growth of beneficial bacteria in the intestines.
Properties: Raffinose is a natural functional oligosaccharide extracted from nutritional supplements (beet molasses or cotton seeds) by physical extraction. Raffinose is a white or slightly yellow crystalline powder, easily soluble in water, slightly soluble in polar solvents such as ethanol, and insoluble in non-polar solvents such as petroleum ether. The melting point of raffinose is 118-119°C. Generally, the crystal contains 5 crystal waters. When slowly heated to 100°C, 5 crystal waters will be lost. The specific rotation [α]D of the aqueous solution is +105°. The melting point of raffinose containing crystal water is 80°C.
Thermal stability: This makes it easy to use in some hot-pressed foods, but when heated to 180°C, raffinose will decompose into molasses and fructose, and molasses may further decompose. Under acidic conditions, the thermal stability of raffinose is still very good, similar to that of sucrose, or even slightly higher. The experimental results show that when kept at pH 3.5 and 90°C for 30 minutes, raffinose hardly decomposes.

Melitriose Powder

Melitriose is also a trisaccharide, but unlike raffinose, its chemical structure may vary depending on the source, but it usually also contains a combination of glucose and two other monosaccharides. Raffinose occurs naturally in certain plants and microorganisms, although it may not be as common in the daily diet as raffinose. Raffinose may have relatively little research on its specific applications and bioactivities, but it may have certain health benefits, such as positive effects on gut health, depending on its specific chemical structure and metabolic pathways in the human body.
Raffinose Powder and Melitriose Powder are both trisaccharide sugar powders, each with a unique chemical structure and potential bioactivity. While the two may be similar in some aspects (such as both are trisaccharides and may be beneficial to gut health), their sources, specific structures, and applications in the food industry may be different. When selecting and using these sugar powders, specific needs and uses should be considered.
