摘要：Nowadays, genetically modified soy, cotton, maize, and rape are cultivated on over 25% of the agricultural areas of the world. The genes introduced into these crops confer them resistance to certain herbicides or toxic products used to control specific pests. In the U.S.A., they cultivate almost 2/3 of the bio-engineered crops at global level. Other countries in which genetically modified crops are cultivated in considerable amounts are Argentina, Canada, Brazil, China, and South Africa. ISO standards to be developed will be relevant globally and will contribute to the facilitation of international trade and services through consistent approaches at international level of identification and analysis of genetically modified foods. Additives authorised at present can be used on the market, but once the updating process is complete, any additive not on the authorised additive list will be prohibited. The food industry uses a large number of natural and artificial aromas, i.e. about 2,600 such substances.
