Feta [SEP] material used
Feta
Feta (Greek Φέτα, "féta", "slice") is a brined curd white cheese made in Greece from sheep's milk or from a mixture of sheep and goat's milk. It is a crumbly aged cheese, commonly produced in blocks, and has a slightly grainy texture. Feta is used as a table cheese, as well as in salads (e.g. the Greek salad) and pastries. Most notable is its use in the popular phyllo-based dishes spanakopita ("spinach pie") and
to cathodically protect metals that are exposed to sea water. A zinc disc attached to a ship's iron rudder will slowly corrode while the rudder stays intact. Similarly, a zinc plug attached to a propeller or the metal protective guard for the keel of the ship provides temporary protection.
With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
