Genetically engineered food how is it made

High-fructose corn syrup and corn oil made from GE corn, soybean oil from GE soybeans, and sugar from GE sugar beets are identical to ingredients made from non-GE crops. While current GE foods are not harmful, they haven't improved our diet, though that may change.

Farmers have started growing soybeans that produce high-oleic oil that could substitute for trans-fat-rich partially hydrogenated oil. And the long-awaited "golden rice," engineered with beta carotene to combat vitamin A deficiency, is expected to be grown by Southeast Asian farmers in Despite industry claims, the FDA does not formally approve the foods or ingredients made from GE crops.

Laws only requires pre-market approval of "food additives" such as aspartame or dyes. In , FDA decided that inserting a gene into a crop does not make the protein it produces a food additive.

Instead, FDA adopted a voluntary process whereby seed developers submit data showing that the GE crop is "substantially equivalent" to its traditional counterparts and does not pose novel health risks. FDA reviews those data and alerts developers to any concerns, but doesn't formally approve the seeds or foods made from the crops.

It is worth noting that many traditional crop varieties, such as some red grapefruit and barley varieties, which could even be grown on organic farms, were developed by blasting seeds with mutagenic chemicals or gamma radiation. In theory, those human-modified crops could pose similar risks as GE crops. But they are not subject to special regulation and have never caused problems. Senator Richard Durbin has supported legislation that would establish an approval process, but it has failed to win support from either ardent GE advocates or opponents.

Myth: Monsanto and other seed developers are the main beneficiaries of GE crops. Seed developers have certainly benefited from engineered crops. They spend millions developing them and then charge hefty premiums to recoup their costs and make a nice profit.

However, others also obtain significant benefits. American farmers growing GE cotton that contains a biological insecticide have greatly reduced their use of highly poisonous insecticides. That cuts their costs and the harms from using those chemical insecticides. Outside the United States, small-scale farmers growing GE cotton in India and China cut their use of insecticides sharply, obtained increased yields, and enjoyed higher income. In China, studies have documented that reduced insecticide use has led to fewer hospitalizations of farmers and reduced harm to beneficial insects and other species.

In the United States, planting herbicide-tolerant soybeans has not reduced herbicide use, but the glyphosate herbicides used are less toxic than the ones previously used. Department of Agriculture economists found that farmers planting those soybeans had greater income because saving time in the field allowed for more off-farm employment.

The reason is that engineered corn reduces insect loads in the whole area, reducing non-GE farmers' need for expensive insecticides. Moreover, farmers growing non-GE crops don't pay any licensing fee to seed companies and often get paid a premium for their crops. Step 1: Identify a trait of interest In order to identify a desirable new trait scientists most often look to nature. Successful discovery of a new genetic trait of interest is often a combination of critical thinking and luck.

For example, if researchers are searching for a trait that would allow a crop to survive in a specific environment, they would look for organisms that naturally are able to survive in that specific environment.

Or if researchers are aiming to improve the nutritional content of a crop, they would screen a list of plants that they hypothesize produce a nutrient of interest. An example of a trait currently in GMOs that was identified through this combination of luck and critical thinking is tolerance to the herbicide Roundup see this article. Although it is not on the market in the United States, Syngenta has designed Golden Rice with an increased amount of pro-vitamin A, which the human body may turn into the vitamin A see this article.

Researchers at Syngenta identified the gene sequence that produces pro-vitamin A and compiled a list of plants to screen with that sequence [9]. With a little luck, there was a plant in nature, maize, that contained a gene that would make Golden Rice produce pro-vitamin A at a level that could meet the nutritional needs of vitamin A deficient communities.

The genomes of plants with the trait are compared to genomes in the same species without the trait, with the goal of identifying genes present only in the former [8]. The genomes of different species with the same trait may also be compared in order to identify a gene, as was the case while developing Golden Rice [9].

In order to expedite this process, Monsanto has developed and patented a method known as seed chipping [8]. Through this method Monsanto shaves off parts of seeds for high-throughput genetic sequencing while leaving the rest of the seeds viable for planting. This creates a genetic database for plants before they are even grown, where a barcode system is used to match plants to their genotypes. Researchers may then use this database to identify new traits of interest as well as to optimize the desirable traits in a crop by selecting for the best genotypes based on plant phenotypes.

Step 3: Insert the desired genetic trait into a new genome Altering the genome of plant seeds is difficult due to their rigid structure.

In biotechnology research it is common to genetically engineer bacteria to produce a desired protein. This is done by using enzymes to cut and paste a DNA strand of interest into a plasmid, which is a small, circular molecule of DNA [10].

Bacteria are then shocked using heat or electricity so that the cells accept the engineered plasmid. By modifying A. First, the genotype of the organisms must be checked so that researchers are only propagating organisms in which the genome was modified correctly. Biotech companies invest large sums into keeping these plants alive and reproducing once they have been successfully created.

The companies use special climate-controlled growth chambers, and biologists often check on the plants by hand to make sure that they are growing as expected [8]. GMO seeds often come with instructions on spacing and nutrition that result from these studies.

The technological advancement from selective breeding to genetic engineering has opened up a large realm of possibilities for the future of our food. As techniques for genetic engineering, such as new RNAi- and nuclease-based technologies that allow for direct modification of the genome see this article and this article , steadily improve, our ability to create new GMOs will also grow [11].

As our scientific capabilities expand it is essential that we discuss the ethics and ideals surrounding GMOs so that we may effectively and safely use this technology in a way that is acceptable to the public.

BBC, 9 Mar. Boyle, Rebecca. Popular Science, 24 Jan. None of the GE foods used today have caused any of these problems. They assess the safety of GE foods to humans, animals, plants, and the environment.

Cotton, corn, and soybeans are the main GE crops grown in the United States. Most of these are used to make ingredients for other foods, such as:. The World Health Organization, the National Academy of Science, and several other major science organizations across the globe have reviewed research on GE foods and have found no evidence that they are harmful. There are no reports of illness, injury, or environmental harm due to GE foods.

Genetically engineered foods are just as safe as conventional foods. The US Department of Agriculture has recently started requiring food manufacturers to disclose information about bioengineered foods and their ingredients.
