High content of erucic acid in triglycerides could increase their solubility in hexane because of the lipophilic effect of the carbon long-chain (C22). However, as this effect was not checked on a large set of high erucic rapeseed samples, it is not appropriate to apply a correction factor to the erucic acid content when analysing high erucic acid rapeseed.<\/p>\n<\/div>\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>4<b><\/td>\n<td>European foreword <br \/> Endorsement notice  <\/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>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>9<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>10<b><\/td>\n<td>6 Apparatus <br \/> 7 Sampling <br \/> 8 Procedure <br \/> 8.1 Preparation of the test sample  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>8.2 Test portion <br \/> 8.2.1 General <br \/> 8.2.2 Case of grains having an oil content exceeding 30\u00a0% by mass (rape, mustard, sunflower and linseed) <br \/> 8.2.3 Case of grains having an oil content between 15\u00a0% and 30\u00a0% by mass (soya beans) <br \/> 8.3 Extraction of the oil <br \/> 8.4 Filtration and drying of the extract <br \/> 8.5 Preparation of the methyl esters  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>9 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>Annex\u00a0A (normative)  General analytical procedures  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Oilseeds.
