I like your pictures, they are pretty close to orange juice. Scattering or absorption or both might be slightly stronger and a bit more to red just a little bit like e.g. r,g,b 1,0.85,0.075.
Defining color of juice by color of Null and absorption color of volume as orange and scattering as white might be worth a test.
I removed the textured scattering, it was too watery. On the photo that lacilaci posted, the scattering looks stronger.
Also made absorption 2x stronger. But it still looks strange.

For some reason when i do the 16bit png to jpeg conversion, the caustics in shadow turn to gray, as of now in 53min render, there is too much noise.

Interesting found, the MLT with very low value of maxconsecutivereject = less noise, but less caustics in shadow.

2,5h BiDirVM and MLT with some blown highligts.
Seems the juice material is now improved.
2,5h MLT, no the shadow is not black, it's dark.jpg
-----------
EDIT

Here is 25% stronger absorption, random sampler and sun sky.
22 hours 17400 spp
