Individual Detection of Genetically Modified Maize Varieties in Non-Identity-Preserved Maize Samples

Journal of Agricultural and Food Chemistry, 2008
In many countries, the labeling of grains and feed- and foodstuffs is mandatory if the genetically modified organism (GMO) content exceeds a certain level of approved GM varieties. The GMO content in a maize sample containing the combined-trait (stacked) GM maize as determined by the currently available methodology is likely to be overestimated ...

Evaluation of Conversion Factors for Genetically Modified Maize Quantification

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 2020
To quantify the amount of authorized GM maize or soybean, conversion factor (Cf) values are required for converting the copy number ratio of GM sequence to an endogenous sequence into weight-based GMO amounts. Cf values are available for the several latest real-time PCR instruments such as QuantStudio5, QuantStudio12K Flex, LightCycler 96, and ...

Genetically modified maize: exploring consumer acceptance

2006
Recent EU regulations have imposed mandatory labelling of all food products that consist of or contain genetically modified organisms (GMOs). Labelling should state that "this product contains genetically modified organisms". This study examines how different label messages may affect the attitude of consumers in tasting a specific food product (corn ...

Quantitative Detection System for Maize Sample Containing Combined-Trait Genetically Modified Maize

Analytical Chemistry, 2005
Various countries have established regulations that stipulate the labeling of agricultural commodities, feed, and food products that contain or are made from genetically modified (GM) material or that contain adventitious GM material in amounts that exceed certain threshold levels.

Genetically modified maize impacts in Honduras: production and social issues

Transgenic Research, 2020
Maize production is one of the most important activities for the Honduran economy, both in terms of area cultivated and food security provided. This article reports the results of a survey undertaken to gauge knowledge, perceptions, opinions, and attitudes of Honduran farmers towards genetically modified (GM) maize.

Acceptability of genetically modified maize by young people

British Food Journal, 2008
PurposeThe purpose of this paper is to examine how label information may affect the acceptability by young consumers of a food produced by genetic engineering methods.Design/methodology/approachA popular snack derived from maize (corn chip) was presented with five different labels (“organic corn”, “conventional corn”, “product that contains genetically

Nutritional Evaluation of Genetically Modified Maize Corn Performed on Rats

Archiv für Tierernaehrung, 2002
The aim of this study was to determine the composition and nutritional value of conventional and transgenic, so-called Roundup Ready (RR) maize with an introduced gene of glyphosate resistance. Crude protein, crude fibre, ash, fat, starch, sugar, amino acids, fatty acid and macroelement levels were determined by chemical analysis. In both maize lines a

Genetic analysis of opaque2 modifier gene activity in maize endosperm

Theoretical and Applied Genetics, 1995
Modifier genes have been described that convert the soft endosperm of opaque2 mutants to a hard, vitreous phenotype. The mode of action and the components of the genetic system involved in this seed modification are poorly understood. We used genetic and biochemical analyses to investigate the number of opaque2 modifier genes, their mode of action and ...

Genetic analysis of opaque2 modifier loci in quality protein maize

Theoretical and Applied Genetics, 2008
Quality protein maize (QPM) was created by selecting genetic modifiers that convert the starchy endosperm of an opaque2 (o2) mutant to a hard, vitreous phenotype. Genetic analysis has shown that there are multiple, unlinked o2 modifiers (Opm), but their identity and mode of action are unknown.

Surveying genetically modified maize in foods marketed in Algeria

Food Control, 2020
Abstract Despite the prohibition of the importation, production, distribution, marketing and use of genetically modified (GM) plants in Algeria, no legislation regarding their use in food and feed production has been established. The present work describes, for the first time, a full-stage study to monitor genetically modified organisms (GMO) in ...
