Chemical Properties |
Pyruvic acid has a sour, acetic odor (similar to acetic acid). It has a pleasant, sour taste with a burning, somewhat sweet note. |
|
Occurrence |
Isolated from cane sugar fermentation broth and from a few plants; also reported found in peppermint, raw asparagus, leaves and stalk of celery, onion, rutabaga, milk, cream, buttermilk, wheaten bread, blue cheeses, cheddar cheese, cottage cheese, provolone cheese, yogurt, beef, Virginia tobacco, beer, white wine, botrytised wine, cocoa and sake. |
|
Uses |
pyruvic acid is an alpha hydroxy acid that can be irritating and is considered difficult to work with. It has a larger molecular size than the most commonly used AHAs. Sodium pyruvate is more commonly used, and is an organic salt. |
|
Uses |
Biochemical research. |
