CANNED JUICE BOTTLED JUICE especially concentrates, destroys its original nutritional benefits. Any canned or bottled juice contains methanol. This is greatest in canned fruit concentrates. The linings of the cans contains BHA, an endocrine disruptor. Methanol is typically bound to pectin. Your body has no enzyme to metabolize that bond it is excreted in your stool and none of the methanol is absorbed into the body. However, the problem occurs when you drink canned or bottle juice, as the methanol tends to then dissociate from the pectin into free methanol, which can be absorbed.
