Cooking Mud Crabs: Why the Color Changes

Above is a GIF I created. After writing on crab mentality and the Filipino First Policy--I got inspired to write about why mud crabs change color. Mud crab dishes are one of my favorite foods in Surigao City. The color is dark but when it's cooked, it goes red. The Tavern Hotel is among the best places to get a mud crab dish. 

Now, it's time to do science as a daily hobby. Sure, I'm no chemist or biochemist. However, researching and studying science as a hobby is sure fun. Here's an explanation from The Conversation:

A crustacean’s exoskeletons contain several chemicals called pigments, which give the crabs and prawns their colour. One of these is an orange-ey pigment called “astaxanthin”. This is a member of the family of pigments that is responsible for colouring many of the yellow, orange and red animals.

When the crustaceans are alive, the astaxanthin is tightly wrapped up and trapped by a special protein called “crustacyanin”. This is why live crabs and prawns usually look bluish-grey.

Once you put a crab or a prawn in a pot of boiling water or on a grill, heat destroys the crustacyanin protein.

Then, the orange-ey astaxanthin is released, turning the shell of the crustaceans bright red. In fact, the degree of colour change tells you if the seafood is properly cooked. If it’s not red enough, it’s probably not cooked enough.

This reminds me of how we've got that joke in high school, "If you answered physical change, go back to first year." I still miss two science teachers who encouraged me to, "Never give up!" As I looked into this research, I wish I had taken Hospitality Management instead of  Business Administration. Right now, I even miss Commerce Week until today!

What's the Use of Complaining About Celebrities and Political Dynasties Running for Politics While DEFENDING Presidential and Rejecting Parliamentary?

2025 is just around the corner for the midterm elections . People keep emphasizing the need to "defend the 1987 Constitution of the Philippines" for any amendments whatsoever. If that were true then we really need to remove Article XVII entirely if the 1987 Constitution of the Philippines was meant to be set in stone (read here ). Several camps whether it's PDP-Laban supporters, Liberal Party of the Philippines supporters, Uniteam supporters, etc.--I can expect social media mudslinging at its finest . I keep talking about the need to amend or even replace the 1987 Constitution of the Philippines. However, they keep acting like it's the best constitution in the world, they cite Atty. Hilario G. Davide Jr. (and others like the Monsods) to idolatrous levels , and when I talk about the parliamentary system--I can expect the whole, "Boohoo! It will never work because we already tried it under Marcos! The proof was Cesar Virata!" However, I wrote a refute on that ...

30 Years of Flor Contemplacion Crybabies Spreading Fake News

Liza Maza Facebook Page It's 30 years since Flor Contemplacion was executed in Singapore. My memories was how some people felt hatred for Singapore, how we were told that "Filipinos are always oppressed." in both values education and civics classes, and how Flor should be regarded as a heroine. The Buwan Ng Wika program came and Flor's execution was also highlighted in the song "Kuko Ng Agila" (Claws of the Eagle). Flor was always romanticized as innocent, a martyr, and even some decent Filipinos bought it once. However, I soon accepted Flor's execution to be what it is-- Singaporean justice .  Some people are still continuing to commemorate Flor--as if she was some kind of Catholic saint or martyr. I could remember rallies year after year, commemorating Flor's "martyrdom". What was also ironic was, at that time, the Vizconde Massacre (read here ) happened and the wrong people were arrested. The public demanded the blood of Hubert Jeffry P....

Taiwan Aboriginal Culture Park Indigenous Bamboo Dance

This is another bamboo dance done by what I believe are Atayal dancers. The dance steps are very similar to what one might find in Nueva Ecija or any indigenous region of the Philippines. What makes it more appealing to me is the absence of Taiwanese Mandarin in the lyrics. Instead, it's lyrics that would sound like the chanting of Filipino indigenous dancers. There are similar yet different movements between Taiwanese aborigines and Filipino aborigines. The Malaysians and Indonesians have settled in several places. The dance movements between Taiwanese aborigines and Filipino aborigines are too similar to be ignored. Even the indigenous language might be very similar.

Atayal Cloth Dance

I may not be going to Taiwan or the Mountain Province any time soon. However, I'm still fascinated by the performances done by both groups. It's no surprise that the DNA tests done would reveal common ancestry between Malaysian, Indonesian, Filipino, and the ethnic groups in Taiwan. The words sound to be very similar to an Ifugao song. Similar yet different. The dances of the Taiwanese tribes in Taiwan share similaritites with the other ethnic groups in Asia. Above is an Ifugao dance demonstration.

The Happy Aborigines Taiwanese Song

  While looking for an Aborigine song that gave me an earworm--I found this interesting aboriginal song. By looking at this video, I suspect that this song is actually a love song between a man and a woman,. It does sound very Ifugao-like as well.
