Soybean was introduced in the U.S. in the 1800s, and it has been proven to have several health benefits. New cultivars of soybeans with varying hull colors have been developed using plantbreeding technology. Canning is one of the effective processing methods to extend the shelf life of products. However, very little information is available on canned soybeans. This research studied the composition of 12 soybean cultivars including two cultivars with brown seed coat (R08-4014 and R09-349), three cultivars with black seed coat (R07-1927, R07-10396, and R09-345), and seven regular cultivars with yellow seed coat (R05-1772, R05-4969, R07-2001, R08-4005, R08- 4006, …

Seed hardness is an important factor in determining soybean suitability for natto production. There is no established methodology for testing seed texture of soybeans. The objective of this study was to develop an efficient method by examining different instruments and seed parameters that could be potentially used for testing soybean seed hardness. Five food-grade soybean genotypes with different seed sizes were used to determine seed hardness and water-absorption capacity. Water absorption capacity was expressed by swell ratios for seed weight, seed dimension, and volume of water changes before and after soaking. Seed hardness test was conducted by a one-bite method …


Effects Of Heating On Hydrophobicity, Viscosity, And Gelling Properties Of Soy Products, Robert S. Walnofer, Navam S. Hettiarachchy, Ronny Horax Jan 2005

The co-product of soybean after oil extraction is the meal, which is rich in protein. From this meal, protein concentrate and protein isolate are prepared and are commercially available as functional ingredients. Thermal treatment is the most common step applied to foods during processing. Changes in structural and functional properties can be affected by thermal or chemical treatments. The objective of this study was to evaluate the effect of heat on surface hydrophobicity, gelling properties, and viscosity of soy meal (SM), soy protein concentrate (SPC), and soy protein isolate (SPI). The soy products were subjected to heat at varying temperatures …


Soybean Seed Yield And Quality Under An Ultra-Short-Season Production System, Lorena Moreno, Tetsuaki Ishibashi, Pengyin Chen, Patrick Fenn Jan 2004

Soybean Seed Yield And Quality Under An Ultra-Short-Season Production System, Lorena Moreno, Tetsuaki Ishibashi, Pengyin Chen, Patrick Fenn

Drought is a major yield-limiting factor for soybean [Glycine max.] in the southern U.S.A. The ultra-short-season production system (USSPS), which uses maturity group (MG) 00 through I cultivars planted in April in Arkansas, may minimize severe yield reduction by drought since this system allows growers to harvest soybeans before severe drought occurs. The objective of this study was to evaluate yield potential and seed quality of Northern MG 00 through I soybean cultivars in a mid-South environment. Average yields of MG 00, 0 and I were 2954, 3585, and 3782 kg ha-1, respectively, under irrigated conditions. Average yield under dryland …


Bradyrhizobium Japonicum And Soybean Symbiotic Response To Glyphosate In Glyphosate-Tolerant Soybeans, Jodie M. Scheele, C. Andy King, Marilynn K. Davies, Larry C. Purcell Jan 2002

Bradyrhizobium Japonicum And Soybean Symbiotic Response To Glyphosate In Glyphosate-Tolerant Soybeans, Jodie M. Scheele, C. Andy King, Marilynn K. Davies, Larry C. Purcell

Soybean (Glycine max) grain contains approximately 40% protein and 6.5% nitrogen (N) on an elemental basis. Therefore, the plant requires an abundant N supply throughout its life cycle, and symbiotic N fixation of soybean with Bradyrhizobium japonicum provides 40 to 85% of the soybean N. Although soybean cultivars have been genetically engineered to withstand the herbicide glyphosate, B. japonicum grown in culture is sensitive to glyphosate. We hypothesized that glyphosate applied to glyphosate-tolerant soybean would inhibit nodulation by B. japonicum unless B. japonicum could also be selected for glyphosate tolerance. Cultures of B. japonicum were challenged with sublethal doses of …
