Mix 690 ml of methanol (4.12) with 240 ml of buffer solution (4.14) and with 70 ml of acetone (4.13).

Mix 110 ml of methanol (4.12) with 820 ml of buffer solution (4.14) and with 70 ml of acetone (4.13). Degas by sonication for 10 min. 4.17 Mixed stock solution, containing ACS-K, ALI, ASP, CYC-Na, DUL, NEO, NHDC, SAC-Na and SCL; mass concentration ρ(sweetener i) = 30 µg/ml to 250 µg/ml. Prepare a mixed stock solution of all nine sweeteners by weighing the given masses of the individual sweetener standards (Table 1) first into a 100 ml beaker and dissolving them in 50 ml of methanol/water (1:1) until complete dissolution. Then transfer the obtained solution quantitatively into a 500 ml volumetric flask and make up to the mark with the buffer solution (4.14). Mix thoroughly by sonication until complete dissolution. SIST EN 15911:2011
NOTE In case of cyclamic acid and saccharin, their sodium salts are used, since they are either not available in free form or poorly soluble. The final concentrations of the individual sweeteners in micrograms per millilitre in the mixed stock solution have to be calculated by using the actually weighed masses. 4.18 Standard solutions. From the mixed stock solution (4.17) prepare a series of standard solutions containing the sweeteners at levels fitting appropriate limits, e.g. the highest concentration of the calibration shall be at least equivalent to 125 % of the given limits, such as those in Commission Directives [3], [4], [5] (see Table D.1), whilst taking the dilution steps within the procedure into account (see Table 2). For sweeteners not authorised by the current EU legislation (ALI, DUL and NEO) fictitious maximum usable dosages (MUD) are assumed at approximately 200 mg/l or 200 mg/kg. The user of the standard has to check whether the limits in Table D.1 are still valid. If not, the mass concentration of the standard substance in the calibration solution shall be adjusted to meet the current MUDs. NOTE The present procedure is simplified by preparing one calibration series for both food matrices. The described calibration series is fitted to canned fruits as the MUDs for canned fruits are in some cases higher than the MUDs for beverages. In case only the latter matrix is analysed the calibration series can be fitted to the MUDs of beverages. Pipette the following volumes (see Table 2) from the mixed stock solution (4.17) into appropriate volumetric flasks (10 ml to 50 ml) and make up to the mark with buffer solution (4.14) and shake thoroughly. SIST EN 15911:2011
Table 3 details the concentration of sweetener i in each calibration standard following preparation described in Table 2. If not all of the sweeteners covered by this standard are the subject of analysis in routine use of the method, when applied to a particular set of samples consideration may be given to reduce the levels of the calibration solutions used for those samples.
