1 Scope
This standard applies to the hydrogenated edible oil as raw material, by melting, decolorization, heating reaction, filtration and other steps processing of food prepared Tim
Additive hydroxyl stearin (also known as oxidized stearin). The food additive hydroxystearin (also known as oxidized stearin) is partially oxidized with stearic acid and
A mixture of other fatty acids in the glyceride.

Testing method
A.1 General provisions
In addition to the provisions of this standard, the purity of the reagents used are analytical pure, the standard titration solution used, the standard solution for the determination of impurities, preparation
And products should be prepared according to GB/T 601, GB/T 602, GB/T 603, test water should be consistent with GB/T 6682 in the three water regulations
set. The solution used in the test refers to the aqueous solution when it is not specified in the formulation of the solvent.
A.2 Determination of acid value (in KOH)
A.2.1 Reagents and materials
A.2.1.1 neutral ethanol solution. 95% ethanol, add 2mL phenolphthalein indicator solution, with potassium hydroxide - ethanol standard titration solution and to reddish
Color, and keep for 30s without fading.
A.2.1.2 Potassium hydroxide-ethanol standard titration solution. c (KOH) = 0.1 mol/L.
A.2.1.3 phenolphthalein indicator solution. 10g/L.
A.2.2 Analysis steps
Weigh the sample 10g, accurate to 0.001g, placed in a conical flask, add 50mL neutral ethanol solution, heating the sample completely dissolved, with
Potassium hydroxide - ethanol standard titration solution titrated to the solution was reddish, and maintain 30s does not fade, that is, the end of titration.
A.2.3 Calculation of results
The mass fraction w1 in grams (in KOH) is in milligrams per gram (mg/g) and is calculated as in formula (A.1)
w1 =
V × c × M
(A.1)
Where.
V --- sample consumption of potassium hydroxide - ethanol standard titration solution volume, in milliliters (mL);
c - the actual concentration of potassium hydroxide - ethanol standard titration solution in moles per liter (mol/L);
M - the molar mass of potassium hydroxide in milligrams per millimole (mg/mmol) [M (KOH) = 56.1];
m --- the quality of the sample, in grams (g).
The results of the test are based on the arithmetic mean of the parallel measurement results. The absolute difference between the two independent determinations obtained under repeatability conditions
The value is not greater than 10% of the arithmetic mean.
A.3 Determination of refractive index (48 ° C)
A.3.1 Instruments and equipment
Abbe refractometer.
A.3.2 Analysis steps
The samples were melted and filtered through filter paper and tested with an Abbe refractometer at 48 ° C.
