Take steak as an example. I only like medium rent when eating steak, that is, it is 3-4 rare. In the past, depending on the thickness of the steak, the central temperature will reach about 50 degrees when each side is fried for 1-2 minutes. At this time, the inside of the steak will be very attractive red and the taste will not be tender. In addition, when processing some seafood products, the temperature can be fixed in the range of 70-90 degrees, thus prolonging the cooking time, thus better ensuring the taste and preserving nutrition. Finally, since the food materials in the vacuum sealed environment have little contact with air and the juice can be locked in the bag, the produced food materials will be more juicy and will not be oxidized and discolored.

? The website is changing, the audience is changing, and the creators are also changing. Today's audience is not in the age when information was relatively isolated as we did at the beginning.

As a result, they are more and more eager to communicate with others, express themselves, desire others to identify with themselves, and people are less and less willing to be isolated. I can put forward a phenomenon that when a person plays with obstacles, the people around him are also willing to be a repeater, for fear that they will not be able to keep up with the topic and will be despised and isolated.
