Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the State Forestry Administration. This standard is under the jurisdiction of the National Forestry Biomass Standardization Technical Committee (SAC/TC416). This standard was drafted by. Huazhong Agricultural University, International Bamboo and Rattan Center, Hubei Ainin Wood Products Co., Ltd., Hubei Sanmu Wood Plastics Division Technology Co., Ltd., Xiamen Geling Biotechnology Co., Ltd. The main drafters of this standard are Xiong Hanguo, Yu Yan, Fei Benhua, Zhou Man, Song Jianjun, Gui Sibin, Tan Jun, Fei Peng, Chen Lei, and Chen Xiaoling. Forest biomass raw material analysis method starch determination

1 Scope

This standard specifies the terms and definitions, principles, reagents, solution preparation, equipment, and operation steps for starch determination in forestry biomass raw materials. Steps, result processing and presentation, repeatability. This standard applies to forest products (such as wood, bamboo, rattan, etc.), forestry residues (such as branches, sawdust, sawdust, shoots, slats, and cuts). The determination of starch in forestry biomass raw materials such as harvesting residues and processing residues such as heads, shells, and kernels.

3 Terms and Definitions

The terms and definitions defined in GB/T 30366-2013 and the following apply to this document. For ease of use, the following is repeated Some terms and definitions in GB/T 30366-2013. 3.1 Forestry biomass forestrybiomass Biomass produced during forestry production and processing. Mainly include forest products (such as wood, bamboo, rattan, etc.) and forestry residues (such as branches Slag, sawdust, sawdust, shoots, slats and truncated, husks and kernels and other processing residues and processing residues, paper-making waste, and waste wood) Energy forest and so on. [GB/T 30366-2013, definition 2.1.3]

4 Principle

Dry-based starch in forestry biomass is hydrolyzed into small molecule sugars by the action of α-amylase, and hydrolyzed by hydrochloric acid into single-reduced ones. Sugar, which can be converted to starch content by reducing sugar content, can be used for quantitative analysis of starch.

5 Reagents

5.1 All reagents were of analytical grade except those specified for the reagents. 5.2 Iodine (I2). 5.3 Potassium iodide (KI). 5.4 Alpha-amylase. The activity unit is 3000~5000. 5.5 Anhydrous ethanol (C2H5OH). ......
