Appendix A
(Normative)
Determination of Surface Oil-Fat-Content
A.1 Principle
After using the petroleum ether solvent to fully extract the creamer sample, evaporate it. After removing the petroleum ether solvent, the remaining materials are the surface oil-fat of the creamer; then obtain the surface oil-fat-content through weighing and calculating.
A.2 Reagents
The reagents used for test include:
a) Petroleum ether: boiling range of 30??C~60??C;
b) Nitrogen: purity no less than 99.99%.
A.3 Apparatus
The apparatus used for test include:
a) Electric heating and drying oven: temperature control accuracy of ??1??C; b) Analytical balance: sensitivity of 0.0001g;
c) Round-bottomed flask: volume of 100mL;
d) Conical flask;
e) Rotary evaporator.
A.4 Operation procedures
Take 8g (accurate to 0.0001g) of sample into the conical flask; add 30mL of petroleum ether; fully shake for 5min; then use filter paper to filer it to the 100mL round-bottomed flask, which has been pre-dried in the 105??C electric heating and drying oven to the constant weight; the filtering slag shall be transferred into the original conical flask. Then use 30mL petroleum ether to shake and extract for twice, the filtrate shall be mixed into the 100mL round-bottomed flask. Place the round-bottomed flask in a rotary evaporator, reduce the pressure and evaporate at the water temperature of 35??C~40??C for 15min; use the filter paper to wipe the moisture outside the flask; blow dry with nitrogen for 30min to remove the solvent. After the solvent is removed completely, weigh the total mass of round-bottomed flask and surface oil-fat-content; then dry by nitrogen till the total mass of round-bottomed flask and surface oil-fat-content is constant.
A.5 Result calculation
Calculate surface oil-fat-content as per the Formula (A.1):
Where:
X ?€? surface oil-fat-content of the sample, in g/100g;
W1 ?€? mass of round-bottomed flask, in g;
W2 ?€? total mass of round-bottomed flask and surface oil-fat, in g;
G ?€? Sample mass, in g.
The calculation results shall retain one digit after the decimal point. A.6 Tolerance
Each sample shall be made into two parallel samples; the result shall be expressed by the arithmetic mean. The absolute difference between two independent determination results obtained under the repeatability condition shall not exceed 5% of the arithmetic mean.
