大家知道white meat 和 black meat指的是什么吗?
THANK YOU VERY MUCH.
Red meat refers to meat that appears red before cooking.Beef,veal,lamb,mutton,venison,pork,goat,rabbit,kangaroo,buffalo meat (that is,meat from bison) and beefalo are all red meats.In fact,all meats derived from mammals are red meats.The United States Department of Agriculture considers all meats derived from livestock to be red meats.
The color of red meat results from its myoglobin content.Myoglobin is a protein that is responsible for carrying oxygen to the muscles of an animal.
Significantly,red meat does not refer to either the degree of doneness,or the coloration,of a meat after cooking.A steak or hamburger therefore remains a red meat whether it is served rare and bloody,or cooked until it is brown or gray,or even burnt to a crisp.And pork,which turns pale or white when cooked,is nevertheless a red meat (despite marketing slogans to the contrary).
In contrast,animal proteins derived from birds (chicken,turkey,duck,pheasant,etc.),fish,reptiles (alligator meat),amphibians (frogs' legs),crustaceans (lobster,shrimp,crab) or bivalves (oysters,clams,mussels) are not red meats,not even those that are red,or reddish-colored,such as salmon,red snapper,or cooked lobsters and shrimp.
White meat refers to any light-colored meat,such as fish,seafood,and particularly poultry.However in a broader sense it includes any of the meats that are considered to be less fatty in comparison with red meats.The term white meat comes from the fact that the meat of chicken is white in color.Examples of white meat are animal proteins derived from birds (chicken,turkey,duck,pheasant,etc.),fish,reptiles (alligator meat),amphibians (frogs' legs),crustaceans (lobster,shrimp,crab) or bivalves (oysters,clams,mussels).Even those that are red,or reddish-colored,such as salmon,red snapper,or cooked lobsters and shrimp are not red meat; instead they are called White meat,or lean meat.Conversely meat that turns white when cooked,like pork,are not white meat despite advertisements claiming so (however some cuts can be comparable in calories to chicken).Red meat is more likely to give you cancer than white meat
white meat还有“赌场上赢到的那部分钱”的意思.
