World consumption of soybean (Glycine max) in 2008 was over 221 million metric tons, with approximately 50% of this supply coming from U.S. production, where soybean plantings on an annual basis are over 77 million ha.Soybeans are desired on the marketplace as a valuable source of protein and oil. The former is primarily used as feed, with some food applications, while the latter is more ...
Soybean (Glycine max L. Merr.) is one of the most important crops in the world. Its major content of vegetable oil made it widely used for human consumption and several food industries.

Genetic modification to improve soybean oil. Soy has been genetically modified to improve the quality of soy oil. Soy oil has a fatty acid profile that makes it susceptible to oxidation, which makes it rancid, and this has limited its usefulness to the food industry.

The demand for commodity soybean oil has been weakened by concerns over trans‐fatty acids in the diet. The Fatty Acid Desaturase 2 (FAD2) genes of soybean determine the levels of monounsaturated fats in soybean oil and vegetative tissues (Schlueter et al., 2007; Tang et al., 2005).

Biotechnology can be used to characterize and eliminate allergens naturally present in crops. Biotechnology has been used to remove a major allergen in soybean demonstrating that genetic modification can be used to reduce allergenicity of food and feed. This provides a model for further use of GM approaches to eliminate allergens.

Soybean [Glycine max (L.) Merrill] seed oil is the primary global source of edible oil and a major renewable and sustainable feedstock for biodiesel production. Therefore, increasing the relative oil concentration in soybean is desirable; however, that goal is complex due to the quantitative nature of the oil concentration trait and possible effects on major agronomic traits such as seed yield ...

Definition. Genetically modified foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering as opposed to traditional cross breeding. In the U.S., the Department of Agriculture (USDA) and the Food and Drug Administration (FDA) favor the use of the term genetic engineering over genetic modification as being more precise; the

To identify genetic variation for fatty acid composition in mature soybean seeds, 4566 M 3 generation seed samples from a chemically mutagenized population were subjected to fatty acid profiling by gas chromatography. In the population, a wide range of variation in the content for each of the five major fatty acids was observed.

Our work has employed a molecular genetic approach to add sulfur-containing amino acids within the structure of the glycinin family of seed storage proteins, which comprise the majority of the protein in soybean seed. Through this approach, modifications in glycinin proteins are made by altering cloned cDNAs encoding glycinin subunits.
