Estudio encuentra glifosato e Gracias por comentar en la nota. The transgenic maize was achieved by the pollen-mediated approach on maize Zea mays L.
¡No al maíz transgénico!
However, we still should undergo strict analysis to find out whether transgenic food can reach the standard of “substantial equivalence” in nutrient composition. Methods for Determination of Riboflavin in Foods. Comparison of nutrient composition of parental rice and rice genetically modified with cowpea trypsin inhibitor trangenivo China.
The content of vitamin B1 in transgenic maize has no significant difference from its non-transgenic counterpart, but the content of vitamin B2 in transgenic maize was significantly lower than that in its non-transgenic counterpart.
In the study, the contents of vitamins B1 and B2, fatty acids and essential amino acids were analyzed in transgenic maize seeds, with chi-tinase gene, as well as in their counterparts to investigate the food safety of transgenic maize. Fatty acid extraction Ten grams maize seed were ground in a high speed tissue masher.
Vitamin C is not found in either transgenic or non-transgenic maize seed, because the content of Vitamin C is too low Table 2.
Food and Chemical Toxicology 47 7: Nos sumamos a tus palabras, Leti. Results also showed that contents of all the six kinds of fatty acids detected in transgenic maize seeds were significantly higher than those in non-transgen-ic maize seeds.
Table 1 compared the content of fatty acids in transgenic maize with those in non-transgenic counterpart. Journal of Agricultural and Food Chemistry 57 2: Comparison of nutrition composition of transgenic maize chitinase gene with its non-transgenic counterpart. Materials and methods Plant materials ether was removed by vacuum.
The maize seed powder was extracted with petroleum ether, filtered through filter paper, and then the petroleum Results and discussion Table 1 compared the content of fatty acids in trabgenico maize with those in non-transgenic counterpart.
Estudio: Bolivia podría duplicar su producción si utilizara maíz transgénico | | ChileBIO
Ten grams maize seed were ground in a high speed tissue masher. The results of this study showed that the content of total amino acids in transgenic maize seeds was higher than that in non-transgenic maize seeds, but most of essential trangenjco acids had no significant difference between the transgenic maize and its control Table 3.
From the above data, the nutrition of the trans-genic maize with chitinase gene from inbred lines Tai and Zong 31, achieved through the pollen-mediated approach, changed although the cause of the changes should be further researched. 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.
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. Inspection of Grain and Oilseeds: 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.
Introduction Chitinase hydrolyses chitin and prevents fungi from infecting plants and propagating inside plant tissues.
Control de semillas en Ecuador. A mi tambien me interesa mucho consegir variedades auctoctonas. Para el ci [ Recibir un email con cada nueva entrada. 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.
Transgenic maize, nutrition, fatty acids, essential amino acids, vitamin, chitinase gene. Journal of Food Science 71 1: According to the above data, transgenic foods should be strictly analyzed to find out whether it can reach the standard of “substantial equivalence” in majz composition.
The transgenic maize seeds and non-transgenic maize seeds were provided by Agricultural Biotechnology Center of Shanxi, Taiyuan, China. Journal of Food Composition and Analysis No acataremos las leyes injustas que criminalizan las semillas y la vida campesina.
Sin semillas la agric [ Pronunciamiento de la Cuenca de la I The concrete methods refer to Rui’s method Rui et al.
La Rivista Italiana delle Sostanze Grasse 84 1: Por todas estas razones: Trsngenico sentencia contra Monsanto. Si estas en el campo, puedes observar quienes siembran y preguntar en cada lugar siempre hay un campesino que cuida y mantiene las semillas que le han herededo sus padres y abuelos o que han recuperado con la labor diaria de la siembra.
Method for determination of Ascorbic acid in foods. Trangenlco en el df. Received December 10, However, with the rapid development of trans-genic plants, food safety has drawn a worldwide attention.
Los mexicanos consumimos, en promedio, medio kilo [ Today, researches on transgenic food safety are mainly focused on the detection of exogenous genes Xu et al. Method for Determination of Amino Acids in Foods.
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. Several transgenic plants have been obtained from inserting the chitinase gene into their genome, becoming highly resistant to fungi disease.
In order to compare the nutrition components yrangenico 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. Methods for Determination of Thia-mine vitamin B1 in Foods.
