| nutrient comparison of fresh and field-dried, green-seeded soybeans. | nutrient composition and biologic utilization of cooked, dried, and ground meals prepared from fresh and field-dried, green-seeded edible soybeans were evaluated. on a dry-weight basis, nutrient content of the fresh and field-dried meals were comparable for protein, fat, calcium, phosphorus, magnesium, copper, and iron; fresh beans tended to have higher zinc content than the field-dried beans. nutrient values for the green-seeded soybean meals were comparable to published values for full-fat soy ... | 1978 | 566776 |
| changes in rat pancreatic protein synthesis after a single feeding with diets containing raw or heated soybeans. | the patterns of protein synthesis following the administration of a single meal containing defatted ground soybeans (rsd) or heated defatted ground soybeans (hsd) were compared. a double label method was used so that the determination of the relative rate of synthesis of an enzyme could not be obscured by a possible alteration of the activity or quantity of the enzyme. rats were given one meal of rsd or hsd and were subsequently killed at different times after the meal. eight hours after the mea ... | 1978 | 566785 |
| somatic crossing-over in glycine max (l.) merrill: activation of dimethyl nitrosoamine by plant seed and comparison with methyl nitrosourea in inducing somatic mosaicism. | the soybean system used for detecting environmental mutagens is analyzed for various types of spots on the leaves of heterozygous y11y11 plants and homozygous y11y11's induced by a nitrosoamine (dimethyl nitrosoamine, dmn) and a nitrosoamide (methyl nitrosourea, mnu). it is shown that the nitrosoamine can be "activated" by the seed (is converted to a true mutagen) without the addition of nadph or s-9 fraction of the liver homogenate as is necessary in animal tissue culture or bacterial studies. ... | 1978 | 569252 |
| improvement of the protein quality of corn with soybean protein. | in most central american countries, lime-treated corn provides 31% of the total protein and 45% of the energy intake, and beans 24% of the protein and 12% of the calories. such diet is low in protein quality and quantity, as well as in energy. to overcome these deficiencies, corn can be supplemented either with its limiting amino acids, lysine and tryptophan, or better still, with whole soybeans which improve not only the amount and quality of the protein consumed but, because of their high oil ... | 1978 | 569424 |
| soy protein utilization in food systems. | soy protein products are utilized in food systems as whole beans, flours and grits, concentrates and isolates, and textured products. soy proteins play a significant role in food systems as a source of supplementary and complementary protein and contribute functional properties such as solubility, water absorption, viscosity, emulsification, texture, and antioxidation. whole soybeans are processed into snack foods, beverages, and fermented foods. soy protein is an ideal supplement for cereal pro ... | 1978 | 569429 |
| evaluation of sclerotinia sclerotiorum as a potential mycotoxin producer on soybeans. | solvent extracts of sclerotinia sclerotiorum sclerotia were nontoxic to mice and chicken embryos; psoralens were not detected. solvent extracts of soybeans inoculated with 10 strains of s. sclerotiorum were toxic on injection but nontoxic on per os administration to mice. the presence of chlorinated hydrocarbons in the soybeans may partially help explain toxicity by intraperitineal injection. | 1978 | 569464 |
| gas-liquid chromatographic determination of sodium 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate residues on soybeans and foliage, soil, milk, and liver. | residues of sodium 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate and its free acid are determined by treating a sample extract with diazomethane to convert the residues to methyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate. this compound is purified by chromatography on florisil and measured by electron capture gas-liquid chromatography. the method has been used on soybeans, soybean foliage, soil, milk, and liver. it can detect 0.01 ppm with recoveries of 70--75%. | 1978 | 569657 |
