This method is applicable to all types of vegetable lecithin.<\/p>\n<p>The purpose of the method is to enable the analysis of lecithin under several regulations. Lecithin [Codex International Numbering System for Food Additives (INS) No.&nbsp;322] is a generally permitted additive and the determination of the TIM is part of many specifications. The purity requirement with regard to TIM content is based on the method specified.<\/p>\n<p>Toluene is the replacement for the carcinogenic benzene, which was used in older methods.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>National foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions <br \/> 4 Principle <br \/> 5 Reagents  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>5.1 Toluene. <br \/> 6 Apparatus <br \/> 7 Sampling <br \/> 7.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>7.2 Preparation of the test sample <br \/> 8 Procedure <br \/> 9 Calculation  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>10 Precision <br \/> 10.1 Interlaboratory test <br \/> 10.2 Repeatability <br \/> 10.3 Reproducibility <br \/> 11 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>Annex A (informative) Results of interlaboratory tests  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Vegetable fats and oils.
