Abstract
After calculation of production figures relating to Bermudagrass and other Texas crops and a review of the processing methods presently employed for the extraction of protein from leafy materials, a model system evolved from the processing of oilseeds was used for the extraction of protein from leafy materials, a model system evolved from the processing of oilseeds was used for the extraction of protein material from Coastal and common Bermudagrasses (Cynodon dactylon). Extraction yields on a nitrogen basis using this aqueous method with wet grinding parparallelede results obtained by others using other leaf materials and processes, ranging from 10 to 80% of the Kjeldahl nitrogen initially present in the grass. pH was found to be limiting in the extractions; extraction from sundried hay did not differ from fresh or frozen grass, and provided a product which did not have the green color normally associated with leaf extracts. Amino acid spectra were similar to those found for other leaves. Extrapolated yields on a crude protein basis are more than 50% greater than obtained from present commercial crops. Evaluation of microscopic data indicated that 80% extraction of the nitrogen was a practical maximum for extractions and that within this limit, more efficient machinery might be designed..
