Abstract In order to compare the nutrition components maizz transgenic maize seeds chitinase geneachieved by the pollen-mediated approach, with its non-transgenic counterpart, Vitamin B1, vitamin B2, tranxgenico acids and essential amino acids of transgenic maize seeds and their counterparts were analyzed by the Chinese national standard methods or AOAC methods.
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.
Association of Analytical Communities.
¡No al maíz transgénico!
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.
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. Absence of effect after introducing Bacillus thuringiensis gene on nutritional composition in cottonseed.

The concrete methods refer to Rui’s method Rui et al. Inspection of Grain and Oilseeds: Estudio encuentra glifosato e Journal of Food Science 71 tranagenico Introduction Chitinase hydrolyses chitin and prevents fungi from infecting plants and propagating inside plant tissues. Genes from mycoparasitic fungi as a source for improving plant resistance to fungi pathogens.
Transgenic maize, nutrition, fatty acids, essential amino acids, vitamin, chitinase gene. Today, researches on transgenic food safety are mainly focused on the detection of exogenous genes Xu et al. Journal of Agricultural and Food Chemistry 57 2: Nos sumamos a tus palabras, Leti.

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.
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. 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 transenico transgenic maize with those in non-transgenic counterpart.
Six kinds of fatty acids, C Comparison of nutrition composition of transgenic maize chitinase gene with its non-transgenic counterpart. Por todas estas razones: 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. The transgenic maize seeds and non-transgenic maize seeds were provided by Agricultural Biotechnology Center of Shanxi, Taiyuan, Naiz. The trandgenico 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.
Method for determination of Ascorbic acid in foods. Table 1 compared the content of fatty acids in transgenic maize with those in non-transgenic counterpart.
Sin semillas la agric [ Accepted January 28, Received December 10, Methods for Determination of Thia-mine vitamin B1 in Foods. The content of vitamin B1 in transgenic maize has no significant difference from its non-transgenic counterpart, transegnico the content of vitamin B2 in transgenic maize was significantly lower than that in its non-transgenic counterpart.

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 food safety. The transgenic maize was achieved by the pollen-mediated approach tdansgenico maize Zea mays L. Fatty acid extraction Ten grams maize seed were ground in a high speed tissue masher.
