Meat does not contain starch. Without starch there is nothing to cause the brown iodine to change color.
When iodine comes into contact with meat, it can turn the meat brown due to a chemical reaction. This reaction occurs because iodine reacts with the amino acids present in meat, causing a color change. However, the iodine itself is not harmful and does not affect the taste or safety of the meat.
Yes, freshwater turtle meat can contain iodine, as iodine is naturally present in various foods, including certain types of meat and seafood. The iodine content in turtle meat may vary depending on the turtle's diet and habitat. However, it is generally not a significant source of iodine compared to seafood or iodized salt. If iodine intake is a concern, it's better to rely on more consistent sources for adequate levels.
There are sugars present in meat. When you "brown" meet you are caramelizing some of these sugars.
Oh, dude, when you put iodine solution on chicken meat, it reacts with any starch present and turns a dark blue or black color. It's like giving your chicken a little science makeover, but I wouldn't recommend serving it up for dinner afterwards! Just stick to seasoning and cooking your chicken the old-fashioned way, trust me.
Iodine can be found in seafood, such as fish, shrimp, and seaweed. It is also naturally present in dairy products, eggs, and some fruits and vegetables, depending on the iodine content of the soil they were grown in. Some table salts are also iodized to help prevent iodine deficiency.
Iron from red meat, iodine from salt, and many cities add flouride to the water
Meat turns brown in the freezer due to a process called oxidation, where the iron in the meat reacts with oxygen in the air. This reaction changes the color of the meat from red to brown.
No.
Yes, red dye.
Iodine is stored throughout the body, including in the muscles and bones. The thyroid gland concentrates the iodine from throughout the body; it is essential for proper growth and development.

An iodine test is used to test for the presence of starch (or polysaccharides, specifically amylose or amylopectin). A Biuret solution test is used as an indicator for peptide bonds within proteins. Therefore, if you get a negative iodine test and a positive Biuret test, you would probably be testing a animal food source (beef, chicken, pork). Overall, any food that doesn't have starch present within it would be appropriate to use. Hope this helps!
