JOE AND WHAT YOU DIDN'T K N O W ger, so it prevents the formation of the off flavors that are produced as meat components react with oxygen. Incidentally, there is absolutely no truth to the rumor that sodium erythorbate comes from earthworms. The rumor probably got started when someone noticed the similarity in pronunciation between "eryth" and "earth" and jumped to the wrong conclusion. 30. " The answer is durians. And what are durians? One of the most interesting fruits in existence. " The only problem is the king needs a bath.
JOE SCHWARCZ substantive research and began a double-ear study. They poured mineral oil into one auditory canal and a 2-percent lidocaine solution into the other. The oil did its job, allowing for an easy roach extraction, but the lidocaine performed in a superior fashion. " The traumatized roach tried to scuttle off, but a "fleet-footed intern" applied "the simple crush method," and that roach was history. Lidocaine was quickly established as the prime treatment for cockroach-in-the-ear. Five years later, a Tokyo physician faced with the classic cockroach problem knew just what to do.
The amount of oxygen that dissolves depends upon temperature (less dissolves as the temperature increases), pressure (less dissolves at higher altitudes), and the amount of other substances already dissolved in the water (fresh water holds more oxygen than salt water). Oxygen in water is good for fish, because they fulfil their oxygen needs by extracting the gas as water passes through their gills, but it isn't so good for metals in washing machines, because they corrode. Sodium sulfite is an oxygen scavenger.
