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.
Manual defrost Samsung refrigerators need defrosting when the freezer coils and cover become covered with ice and the appliance is unable to maintain cool temperatures in either the freezer or refrigerator compartments. Defrosting once per month is generally sufficient to prevent frost from interfering with the unit operating normally.
