Зерновое крахмалосодержащее сырье для производства этилового спирта. Методы определения массовой доли сбраживаемых углеводов

Status: Effective - Introduced for the first time. IUS 5-2013

This standard applies to grain starch-containing raw materials (hereinafter - grain) for the production of ethyl alcohol and establishes the following methods for determining the mass fraction of fermentable carbohydrates (hereinafter - conditional starchiness of grain): - physical and chemical (polarimetric) methods: for grain (except wheat) and grain mixture ; for wheat grain; - express method using near-infrared spectroscopy for rye, wheat, barley and triticale grains; - biological method (fermentation test method) for grain of all crops and grain mixture, which is arbitration

Настоящий стандарт распространяется на зерновое крахмалосодержащее сырье (далее - зерно) для производства этилового спирта и устанавливает следующие методы определения массовой доли сбраживаемых углеводов (далее - условной крахмалистости зерна): - физико-химические (поляриметрические) методы: для зерна (кроме пшеницы) и зерносмеси; для зерна пшеницы; - экспресс-метод с использованием спектроскопии в ближней инфракрасной области для зерна ржи, пшеницы, ячменя и тритикале; - биологический метод (метод бродильной пробы) для зерна всех культур и зерносмеси, являющийся арбитражным
