Is bottled lemon juice as nutritious as fresh lemons?
The 100% bottled lemon juice is suitable for some food preparation applications, such as canning, where the acidity of the product must be high enough to produce the desired reaction.
However, bottled lemon juice does not have the same vitamin C content as fresh lemon juice. It is important to note that vitamin C is sensitive to light and heat and will diminish rather quickly in fresh lemon juice if people do not store it in a cool, dark environment in a non-metal container.
