Since enzymes and other components of the cellular machinery evolved under those conditions, it makes sense that those conditions would continue to be favorable for the interior of living systems.

In general, the interior of cells is thought to reflect the composition (including pH) of the ancient ocean in which life first originated§. Most apple juices have a pH between 3.0 for the more acidic juices and up to about 4.5 for thejuices that contain very little acidity. However, the pH inside cells does tend to be neutral, although the interior of some organelles is quite different‡ - for example mitochondria are usually around pH 8 and lysosomes are usually at pH less than 5. In short, what is good for a cell, tissue, organ, or organism isn't universal - biology typically prefers what ever it is adapted to and the environment isn't constant! Pay particular attention to the table of plant preferences - many plants will be OK at a neutral pH, but pines need an acidic soil. Similarly, many natural environments are not neutral - for example soils can be found with pHs ranging from 3-10 - see: Concord grape juice and grapefruit juice also have a low pH (not quite as.

Which foods are acidic? (n.d.) //lumbia.(I do eventually get around to giving you an answer for the first one.)įirst, note that a neutral pH isn't universally good - for example, if your stomach was at a neutral pH (rather than the normal very low pH) you wouldn't digest your food properly and would be much more susceptible to food borne infections. In addition to lemon juice, lime juice and cranberry juice also have a pH below 3.0.

Here are some specifications: Mellow: 0.35 to 0.45 NFC: up to 0.65 McIntosh: 0.35 to 0.65 (all expressed as malic acid).

A pH meter (Thermo Scientific Orion Benchtop pH Meter accuracy: ± 0.01) was used for monitoring the pH of samples.

On the other side, McIntosh juice can be made from concentrate or NFC or even in combination, and therefore can have a broad range of acidity from lot to lot. All the apple juice samples were maintained at three pH level (4, 6 and 8) using standard solution of NaOH and HCl.
