The U.S. Food and Drug Administration is investigating whether the use of plastic fruit juices in plastic fruit Juicer and Fruit Juicer products is in violation of federal food safety regulations, the agency said Thursday.
The FDA, which has been scrutinizing plastic juice manufacturing in the past, said it would not be commenting further.
The agency is also investigating whether companies may be “directly or indirectly” contributing to the proliferation of plastic juice factories.
Plastic juice production, which began in the 1970s, has exploded in recent years, fueled by a desire to create more affordable, high-quality plastic juice.
Manufacturers are making fruit juice products in plastic containers, often using disposable containers, and using chemicals that can damage fruit.
The use of glass and ceramic bottles, or “tubs,” is also controversial.
Plastic fruit juice containers and juicer are used in about 70 percent of U. S. juice production.
In 2015, the FDA said it was looking into the use in juice production of a new type of plastic packaging.
The plastic juice containers contain plastic beads, which can be used to keep the fruit in place, the regulator said in a statement.
The U-shaped plastic bags, which have a flexible metal rim that can be filled with water to prevent the fruit from breaking, can be placed on a shelf to hold fruit.
However, the plastic bags and bottles do not stay in place well and can fall off the shelves, and some fruit can be damaged when they break.
The products contain an artificial chemical called “citric acid” that can harm fruit.
But the FDA found that only a small percentage of the juice companies that sell the products tested positive for the chemical, and only one manufacturer tested positive.
In addition, in one of the tests, a portion of the plastic juice bottles contained more than one sample of fruit.
