MSG, or monosodium glutamate, is a common and widespread additive in food used mainly for flavor enhancement, but also for preservation. MSG has been used for well over a century as a food additive, but in the last couple of decades anecdotal claims of illness have been linked to MSG consumption.SG is the salt form of glutamic acid, which is a naturally occurring amino acid. Seaweeds and many other plants and vegetables contain glutamic acid.
From Wikipedia, the free encyclopedia. Auto-defrost, automatic defrost or self-defrosting is a technique which regularly defrosts the evaporator in a refrigerator or freezer. Appliances using this technique are often called frost free, frostless or no-frost.
Step 1: Remove everything from the interior. To manually defrost, you need to clean out the interior of your refrigerator and freezer entirely. Keep items that need to stay chilled in a cooler with ice. Step 2: Circulate warm air. Open both doors and allow the warmer, room-temperature air to flow into the freezer and refrigerator to begin the defrosting process.
