Sucrose Fatty Acid Ester E473 - Physico-chemical Properties
| Molecular Formula | C30H58O13 |
| Molar Mass | 626.78 |
| Melting Point | 56-60 °C |
| Storage Condition | Room Temprature |
| Physical and Chemical Properties | The chemical properties are generally white to light yellow powdery or waxy or lumpy, or colorless to yellowish viscous liquid, odorless or slightly greasy, slightly sweet and bitter in taste. Usually there is no obvious melting point, it is stable below 120 ℃, and it decomposes above 145 ℃. Sucrose monoesters are easily soluble in water, diesters and triesters are hardly soluble in water, but easily soluble in oils and non-polar solvents. The HLB value of monoester is 10~16, the HLB value of diester is 7~10, and the value of triester H I.B is 3~7. When heated under acidic or alkaline conditions, it will saponification. Rat oral (sucrose soft fatty acid ester) LD50>30 g/kg,Adl 0~20 mg/kg (tentative, FAO/WHO,1996). |
| Use | Use for food emulsion, China's provisions can be used to emulsify natural pigment, the maximum use of 10.0g/kg; In meat products, sausage, emulsified flavor, candy, bread and ice cream in the maximum use of 1.5g/kg; In the preservative, for eggs, fruit preservation in the maximum use of 1.5g/kg. |

production method
Solvent-free method
Heat the aqueous solution of ethyl stearate (or methyl ester) and surfactant to 100°C, stir, and add more than 0.15mm sugar powder; after all the water is evaporated in vacuum, add the catalyst potassium carbonate powder, React under reduced pressure at 90~160°C, and the produced ethanol (or methanol) is steamed out; dissolve the sucrose and catalyst in the crude sucrose ester with 15% salt water, filter, then use ethanol to remove unreacted ethyl stearate (or methyl ester) to obtain the product.
SNELL method (DMF method)
mix sucrose and fatty acid methyl ester at a molar ratio of 3:1, use dimethylformamide (DMF) as solvent and K2CO3 as catalyst, reflux under reduced pressure at 90~95 ℃ for 12h, and continuously discharge the methanol generated by the reaction; After the reaction is over, dimethylformamide is recovered under reduced pressure, and unreacted fatty acid methyl ester is extracted with petroleum ether; Unreacted sucrose is dissolved with 10% salt water, after the alcohol phase is removed from the solvent, the crude product is obtained, and then the white powder product is obtained by recrystallization with acetone.
microemulsification
dissolve sucrose in propylene glycol to obtain sucrose solution, add emulsifier sodium stearate and catalyst anhydrous potassium carbonate, react with ethyl stearate at 100~140 ℃ and 14.5 ~ 21.1kPa for 6~8h, and the feeding ratio is sucrose: ethyl stearate: anhydrous potassium carbonate: sodium stearate: propanediol = 1:0.6:0.01:0.5:900(Ml). during the reaction, ethanol and, desolvent while reacting, continue to react for a period of time after solvent removal to obtain crude sucrose ester; Dissolve the crude product with acetone, filter, acidify the filtrate and cool to 5~10 ℃, precipitate and crystallize, vacuum dry to obtain pure sucrose ester, and the conversion rate is 98%.
