So does this damage the plastics and lead to plastics leaching into juices?

I understand that high pressure is actually how they start the polymerization of some plastics, you put ethylene under high pressure, and it starts to polymerize to become polyethylene

Howcome under this enormous pressure, why are plastic bottles not just completely destroyed??? What about Bysphenol A and other chemicals.. due they leak from the plastic into the product due to this process?

How it is that the bottles aren't crushed, they have air in them so it seems to me the plastic bottles would crush a bit.
@raulozuna76756 жыл бұрын
That was my question. Any air under that pressure should look for least amount of resistance and gravity should direct it upward in the chamber. This should blow the cap/tops off the bottles. Confused

HPP is a post-packaging solution: already-packaged products like PET bottles of juice or vacuum-packed meats are processed under evenly-distributed pressure which ensures that the packaging is never crushed/distorted. Glass packaging will not work with HPP.

@@timstirrup6948 But the air in bottles is compressible so it should allow bottle to distort a little? And plastic bottle cap can withstand 600 MPa if pressed under "evenly-distributed pressure"? I mean its like a milimeter or 2mm of plastic....will it not crush a little?

@@Julo133 I'm not an expert but I was looking into this too and this is how I belive it works. In order for this technology to work you need bottles filled with fluid to almost max capacity. The air trapped in bottles get compressed causing deformation on the bottles yes. But bottles will be deformed in its weakest point which is the side, where wall thickness is around 0,6mm, not the cap which is thicker. Once air is compressed to its max compression value, the pressure outside and inside of the bottle is uniformed and there is no reason for further deformation of the bottle or the cap. I hope someone with experience or sufficient knowledge can explain better or correct me if I'm wrong.

the food products are not crushed due to the "isostatic principle". It means that all the food products after being loaded into the chamber, they are filled with water. Then the pressure inside the chamber is distributed evenly and uniformly. Imagine if you have an egg submerged in the water, you can apply high pressure to it but it won't be crushed or destroyed.

@@Resist4 HPP (short for High Pressure Pasteurization) is a process that many juice companies use to add shelf life to their juice, and preserve it for longer periods of time (usually up to 45-60 days). Which means you are drinking juice that is as much as 2 months old (and believe us, you can taste the difference). While HPP'd juice stabilizes the bacteria and can preserve some nutrients, the quality of the juice is noticeably diminished, and many great things that are in fresh juice are completely killed off. The molecular structure of the juice is changed, and is no longer considered raw. In fact, the FDA actually made it illegal to use the word 'FRESH' on any labeling of a juice that has gone through the HPP process. Meat Pressure pasteurization strips away naturally-occurring probiotics, proteins, enzymes, vitamins, and minerals. There is no good bacteria left to protect against bad bacteria. After the HPP process, meat is reground, due to the cooked appearance. Regrinding can contaminate meat with harmful bacteria, and further have a deteriorating impact on the chemical composition of the meat; including grinding, mixing, vacuum stuffing and freezing. You see, I could go on and on but people like you pretend to be doctors, pilots, engineers, architects and so on when In all reality you just a keyboard warrior with a pea brain. Do proper research then come back to me little peety.
