Wheat Protein

Sprinkler irrigation on clay soils in southern Finland decreased the protein content of spring wheat flour in five field experiments in the years 1967—70, by 16 ± 4 per cent on an average. The amino acid composition, however, was improved, because the proportion of lysine was increased by 6 ± 4 %. Accordingly, the content of lysine in flour was decreased by irrigation only by 10 ± 5 %. An increase of fertilizer nitrogen from 68 to 144 kg/ha increased the protein content of wheat flour by 19 ± 5 %, but the proportion of lysine in the amino acid composition decreased by 9 ± 4 %. Therefore, the lysine content in flour was increased by nitrogen fertilization only by 8 ± 5 %. It seemed as if urea and ammonium nitrate limestone would have had about the same effect on the quantity and quality of wheat protein. As a consequence of the reversed influences of irrigation and nitrogen fertilization on the wheat protein it was possible, by means of irrigation and an additional nitrogen fertilization, to produce 65 per cent higher grain yields without any noteworthy changes in the contents of protein or amino acids.

Rice albumin from Oryza sativa (Var. Basmati 370) accounts for about 5% of the total seed proteins. A major fraction of rice albumin has been found to be a glycoprotein which is a monomer of 60 kd having iso-electric point 6.54. When rice albumin is digested with trypsin, it shows the presence of 24 peptides as against 28 peptides which were estimated from its amino acid Composition. This indicates the presence of a few peptides which resemble each other in their charge and Rf values. Antibodies against Con A purified rice albumin were affinity purified and were used to quantitate the rice albumin levels during post-anthesis by RIA and ELISA. The latter experiments reveal that maximum albumin is present between 18 and 20 days post-anthesis.
