The objective of this study was to evaluate the differences in composition among six brands of conventional soybean and six genetically modified cultivars (GM). We focused on the isoflavones profile and mineral content questioning the substantial equivalence between conventional and GM organisms. The statement of compliance label for conventional grains was verified for the presence of genetic modified genes by real time polymerase chain reaction (PCR). We did not detect the presence of the 35S…

Soybean (Glycine max L.), is preeminent global agricultural crop due to its alluring application in the manufacturing of a vast variety of foods along with its economic significance on national and

Prospecting for Microelement Function and Biosafety Assessment of Transgenic Cereal Plants

Based on the motivation of the requested biosafety, systematic designs, and analysis of transgenic cereal are presented, and different levels of microelement contents have been measured in transgenic plants.

Mineral and nutritional assessments of soybean, buckwheat, spelt, and maize grains grown conventionally and organically

The present work determined complete mineral profile of four different types of grains (spelt, soybean, maize, and buckwheat) grown under two growing systems – conventional and organic. The contents



Quantification of Roundup Ready™ soybean in Brazilian soy‐derived foods by real‐time PCR

Findings confirm the presence of RR soybean in Brazilian soy-derived food products and that the amount of samples with % RR content above 1% decreases when compared with previously published data.

Compositional variability in conventional and glyphosate-tolerant soybean (Glycine max L.) varieties grown in different regions in Brazil.

There were few differences between the GM and non-GM populations, and most of the variability in the data set could be attributed to regional and variety differences, which were consistent with the expanding literature on the lack of any meaningful impact of transgene insertion on crop composition.


ISOFLAVONE CONTENT AND PROFILE AND ANTIOXIDANT ACTIVITY OF SOY AND SOY PRODUCTS. The objective of this study was to determine the antioxidant activity and isoflavone content and type of soy seeds and

Influence of genotype and environment on isoflavone contents of soybean.

It should be possible to breed for isoflavone content as a quantitative trait in a cultivar development program because of the significant genotype × environment interactions and the differences between the cultivars with the highest and lowest total and individual is oflavone contents were relatively consistent among the 16 environments.

Mass Balance Study of Isoflavones during Soybean Processing

The effects of processing techniques on the distribution of isoflavones were investigated by manufacturing tempeh, soymilk, tofu, and protein isolate. The manufacturing steps causing significant

Teores de isoflavonas em grãos inteiros e nos componentes dos grãos de diferentes cultivares de soja (Glycine max (L.) Merrill)

Due to the higher concentration of isoflavones in the soybean hypocotyls, the food industry has used this component of the bean as a raw material. This paper reports the isoflavone contents found in

Recombinant DNA in meat additives: Specific detection of Roundup Ready™ soybean by nested PCR

A PCR-based method capable of detecting Roundup Ready™ (RR) soybean was employed for meat additives demonstrating for the first time the presence of RR soybean in meat additives.

Glyphosate reduces shoot concentrations of mineral nutrients in glyphosate-resistant soybeans

Irrespective of glyphosate applications, concentrations of shoot macro- and micronutrients were found lower in the near-isogenic GR-cultivars compared to their respective non-GR parental lines.

Efeitos de genótipos, ambientes e de tratamentos hidrotérmicos na concentração de isoflavonas agliconas em grãos de soja

Abstract – The objective of this work was to assess the effects of hydrothermal treatments and theenvironmental and genetic variability on the isoflavone aglycones concentration in soybean [
