Softening of fermented pickles is caused by

  • A.Pectinolytic enzymes, chiefly polygalacturonases of fungal origin
  • B.Excess lactic acid dissolving the skin of the fruit
  • C.Salt crystals slowly forming within the flesh of the cucumber
  • D.Carbon dioxide pressure bursting the cells open from the inside

Answer: A

Enzymes that hydrolyse pectin destroy the material cementing plant cells together and the fruit goes limp. They come mostly from moulds, which is why blossoms and trash must be removed and the fruit kept below the brine where moulds cannot grow.
