What's happening is that the citric acid denatures some proteins. Heat also denatures proteins, so it's similar to cooking, but since no (or, at least, very very little) heat is involved, it's not exactly the same (it won't necessarily kill parasites or bacteria, for example, and only those portions that the citric acid penetrates to will be affected at all).
Yes.
Citric acid is the same acid often found in citrus fruits, like lemons, limes and Oranges.
Pure citric acid has a generic sour flavor, but yes, I suppose it could be used to flavor food.
Gives it flavor
Citric acid can be used for many things... actually Vitamin C contains citric acid...
Citric acid is a crystalline acid (C6H8O7) from the fermentation of carbohydrates or from lemon, lime, and pineapple juices. Citric acid is used in preparing citrates, in flavorings, and metal polishes.
Citric acid is an acid. It is a weak organic acid found in citrus fruits and is commonly used as a flavoring and preservative in food and beverages.
Acetic acid (vinegar), citric acid
Yes, Dr Pepper does contain citric acid as one of its ingredients. Citric acid is used to enhance flavor and act as a preservative in the drink.
Preservative
No, strawberries do not naturally contain citric acid. They have malic acid and citric acid.
Yes, Gatorade contains citric acid as a flavoring agent to enhance its taste. Citric acid is commonly used in beverages to add a tartness that balances sweetness.
To determine the purity of citric acid by titration, you would need to titrate a known concentration of a base (such as NaOH) with a solution of citric acid. The amount of base required to neutralize the citric acid can be used to calculate the purity of the citric acid sample. The purity can be calculated by comparing the experimental results to the theoretical stoichiometry of the reaction.
yes it contains citric acid as a main ingredient
It can be if you can convert the citric acid to a chromophore, i.e., something that is colored. Otherwise, you cannot.
