Genetically Modified Foods in American Cheese
To address the question of whether 90 percent of cheeses sold in the USA are genetically modified (GM), we first need to clarify what constitutes genetically modified food. Genetically modified organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques. In the context of cheese, this primarily pertains to the use of genetically engineered rennet.
Rennet is an enzyme used in cheese-making to curdle milk. Traditionally, rennet is derived from the stomachs of young ruminants, such as calves. However, with advancements in biotechnology, microbial rennet produced by genetically modified microorganisms has become widely available and is often used as a substitute for traditional animal-derived rennet.
Percentage of GM Cheese
While it is difficult to pinpoint an exact percentage of all cheeses sold in the USA that are made using GM ingredients, estimates suggest that a significant portion does utilize microbial rennet. According to various industry reports and surveys, it is estimated that around 70-80% of cheeses produced in the United States may use some form of microbial rennet, which can include genetically modified sources.
However, stating that 90% of all cheese sold is genetically modified would be an overestimation. The actual percentage may vary based on factors such as regional preferences, consumer demand for organic or non-GMO products, and specific cheese types.
Traditional Rennet Usage
Regarding traditional rennet usage in American cheeses, it is estimated that approximately 20-30% of cheeses sold still use traditional animal-derived rennet. This percentage reflects a growing trend among consumers who prefer artisanal cheeses made with traditional methods and those who seek out organic or non-GMO certified products.
In summary:
Approximately 70-80% of American cheeses may be made using some form of microbial rennet.
About 20-30% of American cheeses are made using traditional animal-derived rennet.
Thus, while there is a substantial presence of GM ingredients in the cheese market, it does not reach the claimed figure of 90%.
Final Answer: Approximately 70-80% of American cheeses may be made using some form of microbial rennet; about 20-30% use traditional animal-derived rennet.
