转基因食品英文版

3.Microorganisms
Although GM microorganisms and ingredients produced from them (e,g,GM chymosin in cheese making) have been available for many years, use of GM bacteria and yeasts in foods and in food production has been limited. Many applications are possible, including improvement of traditional food fermentations, production of a variety of metabolic end products, and development of bacteria with enhanced probiotic and other health benefit properties.
Pros and cons of GM food
1. Advantages
Increase crop yields;
Reduce production costs; Enhance crop resistance to pests and virus, Improve agricultural resistant storability; Shorten crop development time; Get rid of the Four Seasons supply; Break down species barriers, Cultivate new species, Produced conducive foods to human health .
Safety and safety evaluation
Risk analysis of generally follows the Codex Alimentarius principles (FAO/ WHO 2003) and consists of the following components: Risk assessment is a scientific examination of the nature of the hazard involved (hazard identification), the extent of the hazard and its risk (hazard characterisation), the likelihood of its effects on particular segments of the population (exposure assessment), and an overall assessmentof the severity of the risk and its consequences (risk characterisation). Risk management is usually undertaken by legislators (state or national jurisdictions) who consider a variety of options before and aft r their implementation, taking into account, where appropriate, “other legitimate factors”. Risk communication involves a dynamic interchange of views among all those involved in assessing and managing risk and the public.

Types of genetically modified foods
1. plant
Many GM crops have now been developed, including soybean, corn, potato, canola and cotton.The first recombinant DNA-derived food plant was a tomato carrying an anti-sense gene to reduce the level of the softening enzyme polygalacturonase to increase the shelf life of the fruit.

Rational view of transgenic technolog
1.While avoiding disadvantages, but not unworthy. 2. Improve relevant laws and regulations, use legal means to ensure the safety of genetically modified organisms. 3. Enhance the legal awareness of scientists, improve ethical of standards research scientists
2. Possible hazards
Make the body resistant to some drugs; Produce harmful toxins; Produce abnormal condition orallergic reaction; Have some impacts on environment.
2. Animals
The genetic modification of animals can be applied to biomedical research, modelling of human disease, production of proteins or other substances for therapeutive aims, as an alternative source of cell tissues and organs for xenotransplantation, and to improve desired features of farm animals and fish,such as disease resistance and food production.GM fish are currently available, but there are no food products derived from GM livestock or poultry.

Genetically Modified Food
Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding (plant breeding and animal breeding), and somaclonal variation.
