The other day, while shopping at our local grocery store(Food Maxx) my eyes bulged with excitement when I saw Mexican papayas on sale. The price was 90c per pound about 20c less off the regular price. Normally, I do not buy Mexican papayas, because they are not as sweet as the Papayas grown in Hawaii or in the Philippines. However, because my wife is constipated ( side effects of her PD medicine), any variety of papaya will be good for her BM.
The above incident reminded me of the article I wrote four years ago about the Papaya trees in my garden, that I am reposting today as follows:
I have about six varieties of papaya trees in my garden at Chateau Du Mer in Boac, Marinduque. Of the six varieties, I like the Solo variety imported from Hawaii. The fruits are small but sweet and firm. The other varieties yields bigger fruits but is not as sweet and firm. (see photo above)
Speaking of Papaya Fruits, I am proud to inform readers of this blog, that my doctoral thesis from the University of Illinois, Chicago, USA was on the Papaya Fruit. The title of my thesis was " Chromatographic Analysis of the Volatile Components of the Papaya Fruit". This was published by the Journal of Pharmaceutical Chemistry, Vol 54, No 6, pages 891-894 dated June, 1965. The following is additional information about the Papaya from Wikipedia.
Originally from southern Mexico, particularly Chiapas and Veracruz, Central America and northern South America, the papaya is now cultivated in most tropical countries, such as Brazil, Bangladesh, Pakistan, India, Indonesia, South Africa, Sri Lanka, Vietnam, Philippines and Jamaica. In cultivation, it grows rapidly, fruiting within 3 years. It is, however, highly frost sensitive.
In the 1990s, the papaya ringspot virus threatened to wipe out Hawaii’s papaya industry completely. Two varieties of papaya, SunUp and Rainbow, that had been genetically modified to be resistant to the virus, were introduced into Hawaii.By 2010, 80% of Hawaiian papaya was genetically modified. Today there is still no conventional or organic method of controlling the ringspot virus. In 2004, non-genetically modified and organic papayas throughout Hawaii had experienced hybridization with the genetically modified varieties.
Papaya can be used as a food, a cooking aid, and in medicine. The stem and bark are also used in rope production.
The ripe fruit is usually eaten raw, without skin or seeds. The unripe green fruit of papaya can be eaten cooked, usually in curries, salads and stews. It has a relatively high amount of pectin, which can be used to make jellies.
Green papaya is used in Thai and Filipino cuisine, both raw and cooked.
The black seeds are edible and have a sharp, spicy taste. They are sometimes ground up and used as a substitute for black pepper. In some parts of Asia the young leaves of papaya are steamed and eaten like spinach. In parts of the world papaya leaves are made into tea as a preventative for malaria, though there is no real scientific evidence for the effectiveness of this treatment.

Green papaya fruit and the tree's latex are both rich in an enzyme called papain, a protease which is useful in tenderizing meat and other proteins. Its ability to break down tough meat fibers was used for thousands of years by indigenous Americans. It is included as a component in powdered meat tenderizers.
Papaya is marketed in tablet form to remedy digestive problems.
Papain is also applied topically (in countries where it grows) for the treatment of cuts, rashes, stings and burns. Papain ointment is commonly made from fermented papaya flesh, and is applied as a gel-like paste. Harrison Ford was treated for a ruptured disc incurred during filming of Indiana Jones and the Temple of Doom by papain injections.
Women in India, Bangladesh, Pakistan, Sri Lanka, and other countries have long used green papaya as a folk remedy for contraception and abortion. Enslaved women in the West Indies were noted for consuming papaya to prevent pregnancies and thus preventing their children from being born into slavery. Medical research in animals has confirmed the contraceptive and abortifacient capability of papaya, and also found that papaya seeds have contraceptive effects in adult male langur monkeys, possibly in adult male humans as well. Unripe papaya is especially effective in large amounts or high doses. Ripe papaya is not teratogenic and will not cause miscarriage in small amounts. Phytochemicals in papaya may suppress the effects of progesterone.
Papaya is frequently used as a hair conditioner, but should be used in small amounts. Papaya releases a latex fluid when not quite ripe, which can cause irritation and provoke allergic reaction in some people. The papaya fruit, seeds, latex, and leaves also contains carpaine, an anthelmintic alkaloid (a drug that removes parasitic worms from the body), which can be dangerous in high doses.
It is speculated that unripe papayas may cause miscarriage due to latex content that may cause uterine contractions which may lead to a miscarriage. Papaya seed extracts in large doses have a contraceptive effect on rats and monkeys, but in small doses have no effect on the unborn animals.
Excessive consumption of papaya can cause carotenemia, the yellowing of soles and palms, which is otherwise harmless. However, a very large dose would need to be consumed; papaya contains about 6% of the level of beta carotene found in carrots (the most common cause of carotenemia) per 100g.
Here's a short video of commercial papaya farming from Australia
* The juice has an antiproliferative effect on in vitro liver cancer cells, probably due to its component of lycopene or immune system stimulation.
* Papaya seed could be used as an antibacterial agent for Escherichia coli, Staphylococcus aureus or Salmonella typhi, although further research is needed before advocating large-scale therapy.
* Papaya seed extract may be nephroprotective (protect the kidneys) in toxicity-induced kidney failure.

Welcome to My Site
If this is your first visit, welcome! This site is devoted to my life experiences as a Filipino-American who immigrated from the Philippines to the United States in 1960. I came to the US as a graduate student when I was 26 years old. I am now in my early-80's and thanks God for his blessings, I have four successful and professional children and six grandchildren here in the US. My wife and I had been enjoying the snow bird lifestyle between US and Philippines after my retirement from USFDA in 2002. Please do not forget to read the latest national and International News in this site . I have also posted some of my favorite Filipino and American dishes and recipes in this site. Some of the photos and videos in this site, I do not own. However, I have no intention on infringing on your copyrights. Cheers!
