Fatty acid of cane sugar of additive agent for food ester
From;    Author:Stand originally
Fatty acid of cane sugar of additive agent for food of level of state of People's Republic of China ester GB 8272-87

Food Additive Fucrose Fatty Acid Ester
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- ━
The sucrose fatty acid that this standard applies to sucrose and fatty acid to ester is changed and be become ester. The product can regard this standard standard as food
Additive, like emulsifying agent, wetting agent, change qualitative agent and fruit to last the agent.
Structural style (with N=1 namely fatty acid ester is sucrose sheet delegate) :
RCOO-CH2
O H CH2OH* O of ─ of ─ of ─ of H ├
H of \ of / of │ of │ of \ of │ / H
│ of \ of H OH of \ of ┘ of ─ of O of ─ of └ of / of │ \ OH H
│ of / of ┤ of ─ of ─ of ├ of ┤ of ─ of ─ of OH ├
H OH OH H CH2OH*
Note * to create 2 ester or the hydroxyl position when 3 ester to can be united in wedlock with fatty acid.
The type that show a gender: (RCOO)nC12OH12O3(OH)8-n;
In type: R-- the alkyl; of fatty acidN -- the hydroxyl ester of sucrose changes number.
