For those in the know, there is actually a skill in trying to distinguish between these two activities. Transgenic soybeans in the process of transgenic, because of the addition of sterilization genes in it, the meaning of this soybean is that it can not be recycled sowing can not be retained. You can't get sprouts from this kind of bean.

Some soybeans can be kept in seed and can be recycled to produce sprouts. That's what we call non-GMO soy. So we in daily life, encounter this black umbilical beans, must not generalize oh. So the quickest way to tell if soy is genetically modified is to sprout it. We can soak the prepared beans in water, soak the beans for more than 12 hours to soak them.

Once the beans are ready to soak, we then pour them into a leaky basket and rinse the beans with water. The proper growing environment for bean sprouts is moisture and heat preservation.

？
We will cover the inside of the leaky basket with a wet towel and wait about two or three days for the beans to take root and sprout. Two or three days later, if such beans have sprouted. That means non-GMO soybeans. People can buy with confidence. If it doesn't sprout, it could be genetically modified soybeans.

？
Therefore, we must not judge whether it is genetically modified or non-genetically modified according to the black umbilical on the soybean
The answer is as follows: There are several methods for GMO and non-GMO identification:
1. PCR method: By amplifying the specific DNA sequence regions of transgenic and non-transgenic species, the presence of transgenic components can be determined.
2. Protein detection method: By detecting the difference in protein composition unique to transgenic and non-transgenic species, the presence of transgenic components is determined.
3. Gene chip technology: Through the comparative analysis of genomic DNA sequences of transgenic and non-transgenic species, to determine whether there are genetically modified components.
4. Enzyme-linked immunosorbent assay (ELISA) : By detecting the difference in protein composition specific to transgenic and non-transgenic species, to determine whether there are genetically modified components.
5. Isotope labeling technology: Through the specific isotope labeling of genetically modified and non-genetically modified species, the presence of genetically modified ingredients is determined.
6. Gene sequencing technology: Through the sequencing of genomic DNA sequences of genetically modified and non-genetically modified species, to determine whether there are genetically modified components.
