① Real small fresh meat is not only "white and red", but also glows.

Fresh pork must be red, uniform, white and shiny. If the meat is dark, the fat lacks luster, and accompanied by an uncomfortable sour taste, the meat is not fresh.

At the same time, it is also suggested that you can choose as many meat packaged independently or vacuum packaged as possible, so as to avoid the infection risk of open food caused by microbial pollution, contact and other factors.Shopping Trolley manufacturer

② Skills for judging the freshness of aquatic products: look at fish scales and fish eyes.

Once the aquatic products are not fresh enough, they will give off a bad smell, which is easier to judge.

But in the aquatic area of the supermarket, the tastes of seafood are mixed together. It's really difficult to tell which fish has "internal flavor".

At this time, it is very useful to learn to see the scales and eyeballs of fish.Shopping Trolley manufacturer

Fresh fish scales are complete, and the eyeballs are full and protruding. On the contrary, if the scales are incomplete and easy to fall off, the eyeballs are flat or sunken, and the eyeballs are turbid, it means that they are not fresh.Shopping Trolley manufacturer
