How to keep food fresh? Based on this question, Swedish engineers Brighton and Montes invented the refrigerator. However, can food be preserved to the maximum extent just by being put in the refrigerator? This also depends on the food.
Clever preservation of bamboo shoots
Freshly harvested bamboo shoots taste great, crisp and sweet. If you can't finish them all at once, you can apply some salt to the cut surface of the remaining fresh bamboo shoots, then put them in the refrigerator to preserve them. Bamboo shoots treated this way can be stored for a relatively long time and will still be quite fresh when eaten again.
Clever preservation of durian
After opening the durian, take out the soft pulp, wrap each piece of pulp separately with plastic wrap, then pack them into a fresh-keeping box or plastic bag, and place them in the freezer of the refrigerator to freeze. Take out a piece to thaw each time you eat it, and the taste will be the same as fresh.
Pork liver preservation method
If the pork liver you bought cannot be finished at once, you can slice the remaining pork liver, put it into a dry, clean, sealed fresh-keeping box, pour in some vegetable oil, mix gently with chopsticks, seal the fresh-keeping box, and it can be kept for about 2 more days.
