ГОСТ 31700-2012

Grain and grain products. Method for determination of acid number of fat

Зерно и продукты его переработки. Метод определения кислотного числа жира

Status: Effective - Introduced for the first time. IUS 3-2013

This standard applies to grain and its products: flour, cereals, germinal flakes, bran and establishes a method for determining the acid number of fat. The essence of the method consists in the extraction of fat by n-hexane, the subsequent removal of the solvent, drying, weighing the fat and titrating the extracted free fatty acids with a KOH solution with a concentration of 0.1 mol

Настоящий стандарт распространяется на зерно и продукты его переработки: муку, крупу, зародышевые хлопья, отруби и устанавливает метод определения кислотного числа жира. Сущность метода заключается в экстракции жира н-гексаном, последующем удалении растворителя, высушивании, взвешивании жира и титровании извлеченных свободных жирных кислот раствором КОН концентрации 0,1 моль/дм3. Диапазон измерений кислотного числа жира от 2 до 200 мг КОН на 1 г жира
