Preservation method of noodle dishes
1, fresh-keeping storage: clean fresh noodles, put them in plastic bags and keep them in the shade. Pay attention to using scissors to cut a centimeter hole in the corner of the fresh-keeping bag, which can dissipate heat well and prevent the sweltering heat from causing decay. This fresh-keeping method can last about a week.
2, drowning storage: Many wild vegetables will make the taste worse if they are stored directly, so the noodle dishes can be drowned before storage to remove the astringency. Put the slender vegetables in a fresh-keeping bag, add 5% salt water, pay attention to exhaust the air in the bag, tie it tightly and put it in a cool place.
3. Salting and storage: It is also a common method to store wild vegetables after salting, that is, the washed noodle dishes are directly soaked in 2-25% salt water for about 10 day, then soaked for about half a month for the second time, and then eaten after washing.
