How are skins of fruits removed by food industry ?

How are skins of fruits removed by food industry for making juices or selling products?

It is by big machines that peel off them, or chemical, ...
Look for instance a kiwi, might be very hard to remove the skin, mango are also quite complex to prepare ...

thanks
seems that there is not so much healthy and traditioanl things around :(


* Steam peeling- Batch process: (BAT in the Food, Drink and Milk Industries, June 2005)
Batch steam peeling is also called “flash steam peeling”. The raw materials such as roots and tubers are exposed to high pressure steam, 1500-2000 kPa in a rotating pressure vessel.

I wonder if it is very healthy. Molecules can be changed.




* Wet caustic peeling: (BAT in the Food, Drink and Milk Industries, June 2005)
The material to be peeled is either placed in or passed through a dilute solution, e.g. 1-2% but as high as 20% of caustic, heated to 80-120°C.

Enjoy having caustic in your body afterwards (cancer might be caustic)



* Flame peeling: (BAT in the Food, Drink and Milk Industries, June 2005)
This technique was developed for onions.



a) Changes in the process:
* Abrasion peeling: (BAT in the Food, Drink and Milk Industries, June 2005)
In abrasion peeling, the material to be peeled is fed onto carborundum rollers or fed into a rotating bowl, which is then lined with carborundum. T

Mechanical is certainly the best


Knife peeling:
fine



* Dry caustic peeling: (BAT in the Food, Drink and Milk Industries, June 2005)
In dry caustic peeling, the material is dipped in a 10% caustic solution heated to 80-120°C,

Enjoy your juices with that (man what a technology)

...wait, you don't like cooked food?

I too want as few added chemicals added to my food as possible, but get your
facts right, 'cancer' is a disease and 'caustic' is a chemical property.
I guess you wanted to say that caustics cause cancer, but in that case you
still cite not enough sources to make a credible argument.

Eh? So you don't ever eat steamed food? Or even cooked food?

Well it was wondered if this would be flamebait and it appears so.

There are other forums more suited to this.
