उत्तर
- Fruit juices containing 66 percent or more of sugar do not deteriorate easily.
- Sugar absorbs excess water, and the result is that water is not available for the growth of microorganisms.
- Sugar syrups containing 66 percent sugar have so little moisture available for microorganisms that their growth is almost stopped, and those already present gradually die.
- Thus, sugar acts as a preservative by enabling the process of osmosis.
- The best examples of food preserved with sugar are jams and jellies. Jellies generally have 60-70 percent sugar content.
