In what ways can solid egg yolk from a boiled egg be processed/preserved?
There is a lot of wastage of egg yolks in my college canteen breakfasts. Almost everyone who takes boiled eggs on his plates eats the whites and throws away the yolk.
I live in a country with the largest number of malnourished children in the world; looking at the wastage daily bothers me quite a bit. Is there any way the yolk can be processed/preserved etc. to make it usable for atleast 4-5 days or so?
I know about breakers which separate the white from the yellow while breaking, but my canteen is....as rudimentary as any. Nothing easier than just boiling the eggs and serving them.
Best Answer
I'll add an answer that doesn't address your question directly, but does address the underlying concern:
If patrons regularly discard part of the dish, you should ask why. With hard boiled eggs cooked in a large scale cafeteria kitchen it's easy to overcook the eggs, just leaving them in the water for hours on end. This results in a greyish, crumbly and unappealing yolk, often discarded.
If you can get the kitchen to improve their process, perhaps with smarter egg boiling appliance, the end result will be more appealing and thus less wasteful.
This, of course, is extremely optimistic, and getting a cafeteria to invest in the tools and training for no immediate return will be very difficult. Perhaps a more feasible alternative is to petition for less wasteful egg preparations, perhaps omelets, where the entire egg is used.

Answer 2
Cooked egg yolks can be frozen, in order to preserve them for a short a mount of time (I wouldn't store them frozen for long, though.) After thawing they can be used for anything a 'fresh' cooked egg yolk could be used, even though the consistence might change during the freezing process.
I used frozen cooked egg yolks for something like egg salad, potato salad or to thicken any kind of spread.
That said: I only ever used this method at home and not in a commercial context. I always am very careful when handling anything with eggs, cooked or raw. The thing is, that egg yolks, especially, are a very good breeding ground for any kind of germ or other stuff, because they are very nutritious (after all they are made for nurturing a baby bird inside the egg). So, anyone accidentally sneezing on the cooked egg yolk or handling it with dirty hands could contaminate an entire batch! Hence, I, too, think that it is somewhat unsanitary for average western standards, but I find it very noble of you to think of any solution to this wasting problem.
Answer 3
Unless you use them in other recipes (for example, google for "what to do with extra egg yolks") there's not much else to do with them.
IMO, The best way to keep them longer would be to salt cure them and use them as a condiment on salad, pasta...
