Pink and red grapefruits are widely grown and marketed as fresh fruits. However these two varieties of grapefruit cannot readily be made into a juice because the color bodies in juice tend to discolor and become brown with age or with pasteurisation.
In order to open the juice market also to the pink and red grapefruits, the food industry has been working to develop technological processes which could remove some (preferably most) color bodies in red / pink grapefruit juice, also known as "decolorization".
Some of those technological processes do not apparently affect the loss of natural turbidity or the pulp content.
This is a very desirable characteristic of any such process, since natural turbidity and the pulp content are viewed as natural characteristics of a wholesome juice.
It is also desirable to preserve other organoleptic properties such as acidity, sugar content, viscosity, also with the purpose of preserving the natural look and feel of the juice.
There are different methods of decolorization of juices. One of them is by centrifugation, which is rather time consuming, as it requires several passes.
Another method of decolorization with the minimal loss of natural juice properties is by vacuum filtration through a bed of coarse diatomaceous earth particles of a certain size (about 10 mkm)
I found a description of a process whereby apple mashes underwent centrifugation, bentoniting and filtration, which removed a substantial part of the color bodies.
The resulting product was slightly pink and the concentrate was "ruby red".
After a test storage of just under 650 hours at 37 degrees C, the juice browned extensively.
The juice concentrate turned orange in color (from ruby red) after over 160 hrs at 37 degrees C and became brown after just under 650 hours.
Steel drums are a convenient bulk container for all kinds of liquid food products or food products in a solution, as well as any other products, liquid or dry
Nestle manufactures a wide variety of food products. I don't know what was in this drum.
High Fructose Corn Syrup" (HFCS)
This substance is widely used in the industrial food processing and preparation and it is believed to be associated with a wide variety of health disorders. More about it is on my site notSmoking.info
