Salt Guide

  • Identify rotten eggs
    There is a tiny air pocket inside an egg, and as time goes by, more air enters inside the egg through the holes in the shell.
    As more air enters into the eggs, the air pocket gets larger and less dense, so the egg floats better in the water.

    With this principle, you can identify a rotten egg by checking whether it floats on the water with sea salt.
  • Prevent enzymatic browning of apples
    Apples contain an enzyme called polyphenol oxidase,
    which oxidizes phenolic compounds in fruits when it meets oxygen.
    Through this process, the apples become oxidized and turn brown.
    Oxidase is activated by copper (Cu) or iron (Fe), and activation is inhibited by chlorine ion (Cl).

    When you add sea salt to water, it is ionized with sodium cation (Na) and chlorine anion (Cl), which can inhibit the activity of oxidase.
  • Preserve tofu
    You can keep a tofu fresh by putting it inside water with a little bit of sea salt and keeping it refrigerated.

    This is because the salt water is similar to bittern.
  • Preserve flowers
    When you add a little bit of sea salt inside the vase before you put the flowers, it helps the flowers last longer and even prevent bad odor.

    Sea salt is useful for cleaning and washing.
    Sea salt does not only absorbs moisture but also has a sterilizing effect while absorbing nearby foreign substances. It is useful for easily cleaning deep, narrow corners where you cannot reach with your hands and washing away oil stains that are not easily removed.
  • Washing a long bottle
    Add a handful of sea salt inside a long bottle, add water and shake to quickly clean the residues inside the bottle.
    Washing an oily frying pan
    While the pan is still hot, add some sea salt and wipe the pan using a paper towel to remove the oil.
    Washing a wooden cutting board
    When you sprinkle sea salt on wooden cutting board with knife marks, you can clean between the marks.
  • Eliminating bad odors in the sink in summer
    Pour a half of a cup of sea salt in the sink and pour hot water over to prevent residues from accumulating or molds from forming.
    Making a moisture remover
    Magnesium chloride in sea salt absorbs moisture in the air and melts once it absorbs. So you can remove moisture by placing it in a small bowl or wrapping it in thin paper and putting it in a humid place.
    Sterilizing toothbrushes
    Keep your toothbrush inside the water with sea salt for 30 minutes to sterilize.
  • Contrast effect
    When there are two flavors that stimulate the taste, the presence of one stimulus makes the other stimulus stronger, and this is called contrast effect. A good example of the contrast effect of salt is adding a small amount of salt in sugar to boost the sweetness of the sugar. You can add a little salt to the red bean porridge or watermelon to make them taste sweeter.
  • Depression effect
    When there are two kinds of taste, the one taste becoming weakened by the presence of another taste is called a depression effect. For example, if you add a little bit of salt to vinegar dressing, the sourness decreases. Adding salt to pickled plums or to sushi is meant to make them salty while softening the strong flavor of vinegar. In the opposite way, salty taste is suppressed in various kinds of salted fish. These foods can be eaten despite the high salt concentration because various amino acids and organic acids in salted fish soften the salty taste.
