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 ā€œastaxanthinā€. 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 ā€œcrustacyaninā€. 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!

Okay, We've Heard These Wise Words by the Late Luis V. Teodoro, But Ever Heard of His Words About th PARLIAMENTARY SYSTEM?!

There's nothing wrong with complaining. Complaining can be counterproductive. However, the problem with the likes of Butthurt Philippines (where I got the quote above) is that they'd rather stick to complaining than get the solutions. Even worse, it seems that the administrator of the Butthurt Philippines Facebook page is that he'd rather look at me as some "DDS troll". Is that the best answer that its owner, who I heard is Lico Reloj (if that's his real name) could even come up with? They'd dismiss me because I'm part of the CoRRECT Movement Moderated Public Forum. I've been insulted for my supposed poor ability in detecting sarcasm. Maybe I should've researched word elongation to detect sarcasm. However, with the way Butthurt Philippines' Facebook page carries things--I doubt it that it's productive complaining.  The quote by the late Luis V. Teodoro is right. I was reminded of why I wanted to move out of the Philippines. I always fel...

Pol Pot's Brutal Regime May Be Summarized by "Hating Everyone Better Than Him"

Documentation Center of Cambodia Archives Two days ago, on April 17, 1975, marked the 50th year since Pol Pot (real name, Saloth Sar) rose to power. The Khmer Rouge only ruled for four years, but it showed one thing--a reign of less than six years isn't necessarily benevolent (read here ). A look at Pol Pot's past may show that he was the typical inggitero--the Filipino word for someone who's easily jealous of others! The History website reveals this brutal detail on Pol Pot's regime, which was most likely fueled by jealousy : Pol Pot was a political leader whose communist Khmer Rouge government led Cambodia from 1975 to 1979. During that time, an estimated 1.5 to 2 million Cambodians died of starvation, execution, disease or overwork. One detention center, S-21, was so notorious that only seven of the roughly 20,000 people imprisoned there are known to have survived. The Khmer Rouge, in their attempt to socially engineer a classless communist society, took particular ...

Is an Impeachment Just as Effective as a Vote of No Confidence?

Talks about impeachment against Vice President Sara Duterte-Carpio are on. However, I'd like to show the problem with the impeachment trial. Who can remember when former president Joseph Marcelo Ejercito aka Joseph Estrada was under impeachment trial? One can say that when Estrada resigned,  that proved that it doesn't matter if the country is presidential or parliamentary (since some economic powerhouses are still under the  presidential system, like South Korea and Taiwan). However, we need to look at the political aspect of the parliamentary system. Is impeachment just as effective as a vote of no confidence? Let's find out! What is impeachment? Impeachment is defined by the Britannica as follows: Impeachment, in common law, a proceeding instituted by a legislative body to address serious misconduct by a public official . In Great Britain the House of Commons serves as prosecutor and the House of Lords as judge in an impeachment proceeding. In the federal government of ...
