Forestry biomass raw material analysis method Protein content determination

1 Scope

This standard specifies methods, reagents and materials, instruments and equipment, and analytical procedures for the determination of protein content in forestry biomass feedstocks. Expression of results, etc. This standard applies to wood, bamboo, rattan, bark, leaves, fruit shells and other forestry biomass raw materials. This standard adopts Kjeldahl method and Dumas combustion method. The former is a classical method for determining protein content and is applicable to each method. A forestry biomass feedstock; the latter is an efficient method for the rapid determination of protein content, and is used to push forward the rapid detection of forestry biomass feedstocks in batches. Recommended for use.

[GB/T 30366-2013, definition 2.1.3]

4 Kjeldahl method

4.1 Principle The protein in the forestry biomass raw material is decomposed under the condition of catalytic heating, and the generated ammonia gas is combined with the sulfuric acid to generate ammonium sulfate, alkalized steaming Distillation ammonia free, absorbed with boric acid, titrated with sulfuric acid or hydrochloric acid standard titration solution, determine the nitrogen content according to the consumption of acid and multiplied by nitrogen For the protein coefficient, you can get the protein content of raw materials. 4.2 Reagents and Materials The reagents used in this standard method are all analytically pure (except as otherwise specified). The water is either distilled or deionized water. 4.2.1 Copper sulfate (CuSO4·5H2O). 4.2.2 Potassium sulfate (K2SO4). 4.2.3 Sulfuric acid (H2SO4). The density is 1.84g/L. ......
