physical property

solubility
Raffinose is soluble in water,

Slightly soluble in polar solvents such as ethanol,It is insoluble in non-polar solvents such as petroleum ether.
The solubility in water is 14% at 20 oC,The solubility increases with the increase of temperature,At 80 oC,It is higher than the solubility of sucrose.

Thermal stability
The thermal stability of raffinose is almost the same as that of sucrose,It remains stable even when heated to 140 oC,Therefore, it is very convenient to use in some foods that need to be processed by hot pressing;
But when heated to 180 oC,Raffinose breaks down into cellobiose and fructose,Molasses may be further decomposed.Under acidic conditions,The thermostability of raffinose is still good under acidic conditions,
Similar to sucrose,Even slightly higher.It was maintained at pH 3.5 and 90 oC for 30 min,Raffinose hardly decomposed.

Maillard reaction (browning reaction)
Raffinose is a non reducing sugar,In the presence of amino acids,The degree of Maillard reaction (browning reaction) is relatively low.When raffinose and sodium glutamate coexist,And heated to 150 oC,The heating time is 2 h,When pH ≤ 4,
The coloring degree (- lgt150) of raffinose was slightly higher than that of glucose,It was lower than sucrose, fructose and fructooligosaccharide;When pH value ≥ 5,The degree of coloration of various sugars was fructose, glucose, fructooligosaccharide, sucrose and raffinose.

Hygroscopicity
Unlike other oligosaccharides,Raffinose crystal powder contains 5 molecules of crystal water,Therefore, even in the environment with 90% relative humidity, it will not absorb moisture and agglomerate,Compared with other oligosaccharide powder, it has stronger hygroscopicity,
This is a remarkable feature of raffinose crystal powder,It is very beneficial to the addition of flaky and powdery food and medicine.Raffinose in the amorphous state,It also has strong moisture absorption and moisturizing ability.
Sweetness
The sweetness is 100% of sucrose,Compared with 10% sucrose solution,The sweetness of raffinose is 22-30.
Quantity of heat
The energy value of raffinose is about 6kj / g,Compared with sucrose (17kj / g) and xylitol,About 1 / 3 of sucrose,1 / 2 of xylitol.
