Salt is added to shredded cabbage for sauerkraut at a concentration of about

  • A.Twenty to twenty five per cent
  • B.Less than one tenth of one per cent
  • C.Two to two and a quarter per cent
  • D.Ten to twelve per cent

Answer: C

Around 2 to 2.25 per cent by weight draws juice out of the cabbage by osmosis and selects for salt tolerant lactic acid bacteria while holding back competitors. Much more than this suppresses the desirable bacteria as well, and much less gives a soft product.
