There is often misunderstanding of lemonâs pH outside the body versus inside the body. Letâs get this straight and expound on 10 benefits of regularly taking lemon juice with warm water (note: NOT equal to lemonade!). Outside the body, lemon juice is acidic (pH is below 7). This is a non-issue.
As intermediates in the metabolic processes of the fruit, these acids are directly involved in growth, maturation, and senescence. Fruit juices have a low pH, because they contain high levels of organic acids. The total acid content varies widely, from approximately 0.2% in pear juice to 0.8% in lime.Some of the major acids in fruits include citric, malic, and tartaric acids.Organic acids also influence the growth of microorganisms in fruit juices and therefore affect the keeping quality of the product. At proper levels certain acids are inhibitory to most bacteria.ome of the major acids in fruits include citric, malic, and tartaric acids.
