北美老玉米80%是GM的,老玉米主要做饲料,也有做食品添加剂,比如淀粉,洋人的pie之类的水果馅,没有 corn starch就全流汤了,所以大量使用。
甜玉米难说,Monsanto 2012年才开始发行甜玉米GM种子,市场占有还没那么快

INFORMATION ON GMO SWEET CORN
Unbeknownst to the majority of consumers, in the summer of 2012 large quantities of
GMO sweet corn appeared on grocery store shelves and roadside produce stands. In 2011, Monsanto announced plans to grow genetically modified sweet corn on 250,000 acres, roughly accounting for 40 percent of the sweet corn market. The sweet corn is being used for frozen and canned corn products, and it is also available fresh across the country.
In 2013, Friends of the Earth released a first-of-its-kind study tracking the prevalence of GMO sweetcorn and brought us some good news! According to the study, out of 71 samples of fresh, frozen and canned corn tested from around the United States, only two of those tested positive (both were confirmed to be Monsanto Seminis® Performance Series™ sweet corn).
Here are key facts you need to know:
What?
GMO sweet corn is genetically engineered to be herbicide resistant (Roundup Ready) and to produce its own insecticide (Bt Toxin). Like all GMOs, genetically modified sweet corn has not been thoroughly tested to ensure that it is safe for consumption.
Who?
While GMO sweet corn has been produced in the past by Syngenta, this is the first attempt by a biotech company to corner the sweet corn market.
Where?
GMO sweet corn can be found in the produce aisle of your local food store and at farmers’ markets and farmstands. It can also be found in processed foods that contain sweet corn
