A cucumber fermentation that has stalled with sugar still present is at risk because

  • A.Sugar reacts with salt to produce an off flavour
  • B.The fruit cannot absorb brine while sugar remains
  • C.The residual sugar can support later spoilage organisms
  • D.The remaining sugar will crystallise inside the fruit

Answer: C

An incomplete fermentation leaves both a higher pH and a food supply, so organisms arriving later have everything they need. A finished fermentation is stable precisely because the sugar has gone and the acid has accumulated.
