The company that "invented" we used techniques that allowed to add to the genetic material of the tomato gene that interferes with the production of the enzyme polygalacturonase. This enzyme has the function of acting directly on the pectin present in the cell walls of the cells of tomato causing "softening" during fruit ripening. Concerns with this variety transgenic tomato ensued mainly because of food safety. Research began to be developed and disseminated with respect to side effects due to high concentration of glycoalkaloids. This transgenic tomato was used in experiments with laboratory rats that showed negative effects such as lesions in the stomach due to plant toxins in high concentration. These and other results were not published at the time, only some time later. Lack of responsibility of the company or the U.S. government? How are ethical issues? SEARCH Biology Pectin Compound with polysaccharide widely found in the cell walls of plants. Research the International Conference Asilomar, California, USA, occurred in 1975 and report the main ideas discussed regarding the use of biotechnology. Although the scientific community has been shown to be concerned about possible negative health effects, the U.S. government decided to large-scale production of genetically modified foods in the early 1990s. Interesting fact is that the U.S. government itself waved guarantees for biotech companies, that supermarkets will soon be selling genetically modified foods. The FDA - Food and Drug Administration - U.S. health agency with similar function ANVISA in Brazil, adopted without reservations, the widespread tomato and other genetically modified foods. In 1993, the FDA made the decision to steer the company regarding the safety of GM foods. ANVISA - National Agency for Sanitary Vigilance - is responsible for promoting the protection of the health of the population through the sanitary control of production and marketing of products and services subject to sanitary surveillance, including the environments, processes, inputs and technologies related to them. In addition, the Agency has control of ports, airports and borders and dialogue with the Ministry of Foreign Affairs and foreign institutions to address issues in international health surveillance.

The food you consume daily is transgenic?

Tvrtka koja "izumio" smo se tehnike koje mogu dodati na genetskom materijalu od rajčice gena koja ometa proizvodnju enzima polygalacturonase. Ovaj enzim ima funkciju djeluju izravno na pektina prisutan u staničnim stijenkama stanicama rajčice uzrokujući "omekšavanja" tijekom dozrijevanja. Zabrinutost s ovom rajčice sorte transgenih uslijedila uglavnom zbog sigurnosti hrane. Istraživanje počeo se razvijati i širiti s obzirom na nuspojave zbog visoke koncentracije glycoalkaloids. Ovaj Transgenična rajčica koristi u eksperimentima s laboratorijskih štakora koji su pokazali negativne učinke kao što su lezije u želucu zbog biljnih toksina u visokoj koncentraciji. Ovi i drugi rezultati nisu objavljeni u to vrijeme, samo nešto kasnije. Nedostatak odgovornosti tvrtke ili američke vlade? Kako su etička pitanja? TRAŽI Biologija Pektin Spoj s polisaharide naširoko nalazi u staničnim stijenkama biljaka. Istraživanje Međunarodna konferencija Asilomar, Kalifornija, SAD, dogodio se u 1975 i izvješće glavne ideje raspravljalo o korištenju biotehnologije. Iako znanstvena zajednica je pokazala da se brine o mogućim negativnim učincima na zdravlje, američka vlada je odlučila do velikih razmjera proizvodnje genetski modificirane hrane u ranim 1990-ih. Zanimljiva je činjenica da je vlada SAD-sama mahnuo jamstva za biotehnološke tvrtke, koja će uskoro biti supermarketi prodaju genetski modificirane hrane. FDA - Food and Drug Administration - Američka zdravstvena agencija sa sličnom funkcijom ANVISA u Brazilu, usvojen bez rezervacije, rasprostranjenog rajčica i druge genetski modificirane hrane. Godine 1993, FDA je donijela odluku usmjeriti tvrtku o sigurnosti GM hrane. ANVISA - Nacionalna agencija za sanitarnu budnost - odgovoran je za promicanje zaštite zdravlja stanovništva kroz sanitarnu kontrolu proizvodnje i stavljanje u promet proizvoda i usluga koji podliježu sanitarnom nadzoru, uključujući sredinama, procesima, ulazi i tehnologije odnose na njih. Osim toga, Agencija ima kontrolu nad lukama, zračnim lukama i na granici i dijalog s Ministarstvom vanjskih poslova i stranim institucijama za rješavanje problema u međunarodnoj zdravstveni nadzor.

Hrana koju konzumiraju svakodnevno je transgenetska?
