How is fruit juice absorbed into the walls of the fruit. Does the juice sit in the walls of the fruit waiting to be released or is it absorbed in the walls of the fruit. Are all fruits the same? Most important…do grapes and olives share a quality different from other fruits in regards to the extraction of their juice.

At least one of us is confused here. It sounds like you’re saying that the juice starts off outside the fruit, and then gets soaked up?

He’s asking, “Where does the juice come from? Is it floating around loose inside the fruit, or is it embedded in the cells and cell walls of the fruit?”

How it works in oranges.

The sacs (vesicles) are actually swollen (plump), specialized hairs. According to K. Esau (Anatomy of Seed Plants, 1960), the juice sacs originate as multicellular hairs in which the interior of the enlarged distal part breaks down and fills with liquid. The juice sacs constitute the fleshy, edible pulp of an orange and are the source of the sweet juice.

Thanks for the reply. I really need to know if the way juice is stored in grapes and olives is unique, compared to other the way juice is stored in other fruits.

Thanks for your help

I would imagine citrus fruits are different to olives. Oranges etc have distinct juice filled pouches, but olives tend to release juice on chewing, like apples.

Umm. I don’t thinkI really know.
