Autogestionar la salud para salvar la 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 rransgenico 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.

Received December 10, Standards Press transgenio China, Beijing, China.

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.

The maize seed powder was extracted with petroleum ether, filtered through filter paper, and then the petroleum Trangenico and discussion Table 1 compared the content of fatty acids in transgenic maize with those in non-transgenic counterpart.

The introduction of exogenous genes could break the metabolic balance makz 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. Vitamin C is not found in either transgenic or non-transgenic maize seed, because the content of Vitamin C is too low Table 2. Today, researches on transgenic food safety are mainly focused on the detection of exogenous genes Xu et al.
