“…They tested a 45 min, 30 °C, primary hydrolysis step and a 1 h autoclave secondary hydrolysis, instead of a 4 h boiling water reflux step. That same year, Saeman et al ( 22 ) described three sugar detection techniques for analyzing wood acid hydrolysates. The authors reported an electrometric titration, a reducing sugar assay, or a yeast sorption (i.e., a standardized fermentation) method to measure the sugars released from lignin hydrolyses.…”

As interest in lignocellulosic biomass feedstocks for conversion into transportation fuels grows, the summative compositional analysis of biomass, or plant-derived material, becomes ever more important. The sulfuric acid hydrolysis of biomass has been used to measure lignin and structural carbohydrate content for more than 100 years. Researchers have applied these methods to measure the lignin and structural carbohydrate contents of woody materials, estimate the nutritional value of animal feed, analyze the dietary fiber content of human food, compare potential biofuels feedstocks, and measure the efficiency of biomass-to-biofuels processes. The purpose of this paper is to review the history and lineage of biomass compositional analysis methods based on a sulfuric acid hydrolysis. These methods have become the de facto procedure for biomass compositional analysis. The paper traces changes to the biomass compositional analysis methods through time to the biomass methods currently used at the National Renewable Energy Laboratory (NREL). The current suite of laboratory analytical procedures (LAPs) offered by NREL is described, including an overview of the procedures and methodologies and some common pitfalls. Suggestions are made for continuing improvement to the suite of analyses.

“…The usual procedure is the measurement of the difference in reducing powers before and after yeast sorption. It was found by Saeman and co-workers that the fermentability of acidhydrolyzed wood sugar worts as determined by the rapid yeast sorption method was essentially the same as when determined by the conventional fermentation method (9).…”

The effectiveness of corn meal and soybean oil meal as carriers was due evidently to the presence of antioxidants which supplemented those in the concentrates. Soybean oil meal was more effective in preventing autoxidation than com meal. The greater rapidity in the loss of vitamin A or /J-carotene when the products were mixed with glucose than when stored alone may be due either to greater dispersion of the products or to the presence of oxidants in the glucose.The two products that were the most stable alone (Nos. 1 and 2) were also the most stable when mixed with glucose. They retained more than 60% of their initial vitamin A content after 6 months of storage when mixed with glucose as compared with 37% and less for the other products. SUMMARYSeven different dry commercial vitamin A products containing 150 to 1500 micrograms of vitamin A or carotene per gram retained 60 to 85% of their initial vitamin during a 6-month storage period in the dark at room temperature. The highest stability was shown by products which employed vegetable meals or the antioxidants which they contain.A portion of each of the products was mixed with corn meal, soybean oil meal, or glucose in such proportions that the mixtures contained approximately 10 micrograms per gram of vitamin A or its equivalent in esters or ß-carotene. Soybean oil meal (expeller) improved the stability of the vitamin in most of the products.Ground yellow corn showed a similar effect but to a lesser degree.Glucose (cerelose) diminished the stability in all cases.
