I get contact dermatitis from the sap too. I can eat the papaya. I just have to be careful when I pick and peel them. For that I use disposable gloves.
I have not tried to freeze papaya, but I don't really have to. If it is like mango, it would have to be eaten frozen or juiced. You can put the chunks in fruit salad or ambrosia, juice it, make green papaya salad, or papaya pickles (anchara), papaya is also used as a meat tenderizer the papain is a proteinase that disolves protein. a couple of slices of papaya layed on some meat a couple of hours before cooking helps to make it tender. Don't leave it too long or you get a grainy texture. Most of the time 1/2 papaya is eaten with cottage cheese , lemon, or lime juice. It is high in fiber and old people like it to keep them regular since many of them don't do much walking. Green papaya is used to make chicken and papaya soup. The green papaya is like squash when it is used that way. The same recipe can be use with chayote instead. The chayote is firmer so won't mush as quickly.
You can pick papaya as soon as it shows a yellow streak. If you have a really sweet papaya, you have to pick it at this stage and let it ripen. Birds will go after the sweetest fruit. When I see a tree full of ripe fruit that isn't being bothered by the birds, I know the fruit isn't very good and it would be a tree I would just cut down.
Most papaya here are hybrids. What most people are concerned with is not the taste from saving seeds since it is hard to control interbreeding with so many trees around. Basically, most people will only keep trees that have good flavor anyway, so keeping trees with sweet fruit, usually gets you offspring with good fruit. Occasionally, you get one that isn't that great, but it gets cut down in that case so it would not be used to reproduce. To some people knowing the pedigree is important if they are concerned about GMO papaya. The tree and fruit look the same and the fruit is good. You cannot tell a GMO tree from a non GMO unless you are in a papaya field with PRSV virus. Then the GMO will be the only healthy trees around. 90% of all papaya grown commercially here is GMO. In the 70's the papaya industry in Puna nearly collapsed because of PRSV. There are a few farms that are growing non GMO papaya but because wild papaya will sometimes grow, they have to rougue out any papaya they have not planted. The papaya comes from the birds dropping seeds from papayas they have eaten. They also have to ensure the pedigree of their seeds. I have both kinds.
At home, I usually grow the non GMO Waimanalo Low bearing, but at my community garden where squash is grown everywhere only the GMO papaya will produce. My best low bearing papaya came from my neighbor. The tree has no pedigree but I suspect it has GMO genes because it is healthy around squash. That is the thing, GMO trees are totally capable of crossing with non-GMO trees and only recently has a practical test been developed to test for it.
Papaya farmers worldwide now are looking to GMO to save their crops from virus. They cannot actually use the GMO seeds from Hawaii since their trees and virus have different genetic markers but they can use the techniques that were used to develop the PRSV resistant papayas here.
People want to stay away from GMO's out of fear that they have not been researched enough. Reality is mostly, that is what it is, fear. They have been eaten by millions of people for over 40 years. Japan, which was a GMO holdout, finally decided they were safe enough to import. No one has turned into an alien yet or had any issues that can be linked to the consumption of GMO papaya.
What was the genetic modification. The modified gene causes an infecting virus to be coated with a protein coating so it cannot cause the PRSV symptoms.

In 2012 the organic movement successfully legislated a ban on further GMO crops being planted on Maui. This was over the objections of the local farmers and the scientific community who said it would hurt other farmers not just the GMO farmers. And there was no science behind the oppositions claim that GMO's were bad. In fact the organic movement not only did not offer any evidence of harm, their claims that GMO's were not tested enough were a bit ridiculous since no one can guarantee 100% and they are demanding 100% certainty. GMO's have had more scrutiny than most other products. Even organic fruits and vegetables cannot guarantee they are 100% safe. You just have to look at all of the recalls on organic products that have been contaminated by bacteria like salmonella and ecoli from runoff. It actually makes it illegal for anyone to grow GMO plant on the island. Technically someone growing a papaya in their backyard, whether they know it or not, if it is GMO it is illegal. The legislation was targeting Monsanto and Pioneer but it also made it harder for smaller farmers to get basic things like fertilizer, farm equipment, container space since they small farmers orders are piggybacked on the larger corporation orders by the local ag supplier and without the larger company's business, their operating costs will rise because they do not have the economies of scale.
Happy gardening in Hawaii. Gardens are where people grow.
