The chicken in the mentaiko cream potato dish was too red..
Q:
The chicken in my mentaiko cream potato was so red that it made me anxious. I even took a photo. In the end, I stopped eating it. After eating it, I had to fight the anxiety of getting gastroenteritis for about three hours, and I felt terrible
A:
We apologize for the inconvenience caused by the reddish color of the chicken. Regarding the "Steam-Cut Chicken" used in this menu, we confirmed that it is a pre-cooked item that is also heated during preparation in the central cafeteria. Furthermore, upon checking with our food product manager, we learned that due to the nature of chicken, there is a phenomenon known as "pinking," in which chicken retains a red color even after cooking, and this may be the case in this case. Regarding pinking, the following is an explanation: Meat contains a pigment protein called myoglobin, which generally denatures and oxidizes when heated, turning brown. However, some meat contains heat-stable myoglobin, which remains resistant to heating. Heat-stable myoglobin has the ability to prevent iron oxidation, maintaining the iron's reduced state, which may result in the meat appearing red. Additionally, depending on the condition of the ingredients, a strong red color may remain. This could be due to factors derived from the ingredients, such as: 1) the presence of bloody parts close to blood vessels, resulting in a red color that persists (stabilizes) even after cooking; 2) insufficient bleeding after slaughter, resulting in blood remaining throughout the raw meat; or 3) some kind of stress on the animal causing an increase in the amount of blood, which affects the final product. Since the meat is steam-heated at over 70°C for one minute during production, and our central cafeteria also heats it at 220°C for 10 minutes in humidified mode, the health risk is considered extremely low. Furthermore, if you have any concerns about our menu in the future, please speak to a staff member immediately. Once again, we apologize for any inconvenience this may have caused
