The chicken in the Mentai Cream Potato is too red...
Q:
The chicken in the mentaiko cream potatoes was so red that I was worried. I also took some photos. Eventually I stopped eating. I have to worry about getting gastroenteritis for about 3 hours after eating, which is the worst feeling.
A:
We apologize for the inconvenience caused by the redness in the chicken. Regarding the "steam cut chicken" used in this menu, we have confirmed that it is a cooked product that is also heated at the time of cooking at the central cafeteria. I also checked with the food staff and found out that due to the nature of chicken, there is a phenomenon called ``pinking,'' in which the chicken turns red even when it is heated, and this is a possibility in this case. The following is about pinking. Meat contains a pigmented protein called myoglobin, which generally denatures when heated, becomes oxidized, and turns brown, but it may contain heat-resistant myoglobin, which does not denature even after heating. . Heat-resistant myoglobin has an anti-oxidation effect on iron and maintains the reduced state of iron, which may cause the meat to take on a red color. In addition, depending on the condition of the raw material, a strong redness may remain. (1) A red tone remains (fixed) even after heating due to mixing of parts of blood close to blood vessels. (2) Blood is not sufficiently removed after slaughter. Blood remained throughout the raw meat (3) Some stress on the living body increased the amount of blood in some areas, affecting the final product, and other factors originating from the raw materials are suspected. During manufacturing, our products are steam-heated at over 70 degrees Celsius for one minute, and at our central cafeteria, we heat them at 220 degrees Celsius for 10 minutes in humidification mode, so the health risks are considered to be extremely low. Also, if you have any concerns about our cafeteria menu in the future, we would appreciate it if you could speak to the staff on the spot. Once again, we apologize for the inconvenience caused.
