Rechazo internacional a la siembra de maíz transgénico en México

However, we still should undergo strict analysis to find out whether transgenic food can reach the standard of “substantial equivalence” in nutrient composition. Amino acids are components of protein and the product of the exogenous gene is protein; therefore, whether the insertion of exogenous gene can result in a change of amino acid contents should be an important aspect for transgenic malz safety.

Introduction Chitinase hydrolyses chitin and prevents fungi from infecting plants and propagating inside plant tissues. Porque tengoentendido que por estos dias hay una consulta popular que se va hacer y que esta publicada para poder firmar y decir NO al maiz transgenico.

Estudio: Bolivia podría duplicar su producción si utilizara maíz transgénico | | ChileBIO

Methods for Determination of Thia-mine vitamin B1 in Foods. A new kind of fatty acid emerging from transgenic cotton seed. Para el ci [ Autogestionar la salud para salvar la Vivo en el df.

Vitamin C is not found in either transgenic or non-transgenic maize seed, because the content of Vitamin C is too low Table 2. Methods for Determination of Riboflavin in Foods. So transgenic food should be strictly analyzed not only regarding the exogenous gene and exogenous protein, but also about other components which seem not directly related to the exogenous gene, even though many researches have proven the nutrition of transgenic food showed no changes Han et al.

Nos sumamos a tus palabras, Leti.

No permitiremos que se pierdan nuestras semillas, ni que se contaminen por transgenes propiedad de empresas transnacionales. Abstract In order to compare the nutrition components of transgenic maize seeds chitinase geneachieved by the pollen-mediated approach, with its non-transgenic counterpart, Vitamin B1, vitamin B2, fatty acids and essential amino acids of transgenic maize seeds and their counterparts were analyzed by the Chinese national standard methods or AOAC methods.

Journal of Food Science 71 1: The transgenic maize was achieved by the pollen-mediated approach on maize Zea mays L. No acataremos las leyes injustas que criminalizan las semillas y la vida campesina. Acta Botanica Sinica 43 3: The introduction of exogenous genes could break the metabolic balance in the plant, or change some physiological and biochemical courses, which could result in food safety problems, including changes in nutrition such as content of protein, vitamins, essential fatty acids, amino acids, etc.

Monsanto solicita tres permisos para sembrar maíz transgénico

Official Methods of Analysis. Method for Determination of Amino Acids in Foods. The transgenic maize seeds and non-transgenic maize seeds were provided by Agricultural Biotechnology Center of Shanxi, Taiyuan, China.

Today, researches on transgenic food safety are mainly focused on the detection of exogenous genes Xu et al.


Method for determination of Ascorbic acid in foods. Standards Press of China, Beijing, China. Inspection of Grain and Oilseeds: Genes from mycoparasitic fungi as a source for improving plant resistance to fungi pathogens.

Lorito et al, Maize is one of the three biggest yield cereal crops and most of maize diseases are fungal diseases, so inserting the chitinase gene into maize is surely an effective approach to resist fungi diseases and ensure food security. Received December 10, Chitinase hydrolyses chitin and prevents fungi from infecting plants mziz propagating inside plant tissues.

Pronunciamiento de la Cuenca de la I Association of Analytical Communities. Estudio encuentra glifosato e The results showed that the contents of all the six kinds of fatty acids detected in transgenic maize seeds were significantly higher than those in their non-transgenic counterpart, the content of vitamin B2 in transgenic maize was significantly lower than that in non-transgenic maize seeds, the content of total amino acids in transgenic maize seed was higher than that in non-transgenic maize seeds, while vitamin B1 and most of essential amino acid have no significant difference between transgenic maize and non-transgenic maize seeds.

According to the above data, transgenic foods should be strictly analyzed to find out whether it can reach the standard of “substantial equivalence” in nutrient composition.
