The role of ferrous sulfate
[Use 1] Used in the production of iron salts, iron oxide pigments, mordants,
water purifiers, preservatives, disinfectants, etc., as anti-anemia drugs in medicine
[Use 2] Nutritional supplement (iron fortifier); Fruit and vegetable coloring agent.
For example, the pickled products used together with burnt alum for eggplant
can form stable complex salts with their pigments to prevent discoloration caused by
organic acids. However, it should be noted that if the amount of iron is too much,
it will turn into black ink, and if the amount of alum is too much, the meat of the
pickled eggplant will be too firm. Formulation example: 300kg long eggplant, 40kg salt,
100g ferrous sulfate, 500g burnt alum. It can still be used as a hair coloring agent for
black beans, candied broad beans, kelp, etc. Foods with a lot of tannins should not
be used in order to avoid blackening. It can also be used for sterilization and deodorization,
but the sterilizing power is extremely weak.
The leuco-based pigment contained in beans is colorless in the reduced state,
and becomes black when oxidized under alkaline conditions. The reducibility of ferrous
sulfate can be used to achieve the purpose of color protection. The dosage is 0.02% to 0.03%.
