In a high enough concentration it can be. Cells (bacterial or otherwise) can only prevent osmosis across their membranes to a limited extent. When a solution is concentrated enough (i.e. hypertonic), it can dessicate the cells, therefore retarding microbial growth and rendering potential pathogens inert .

Some examples of sugar-based preservatives include various syrups (i.e. maple), honey, and fruit preserves (jams). In particular it is useful to note that jam does not require raising temperatures above 104C to kill botulinum spores; although most operations will pasteurize the stock to kill fungal spores which may grow on the top layer of the jam due to recondensed water).

What is chemical preservation?

Chemical preservation refers to the use of chemicals or additives to prevent the growth of bacteria, fungi, and other microorganisms in food or other perishable items. These chemicals help extend the shelf life of products by inhibiting spoilage and maintaining quality. Some common chemical preservatives include salt, sugar, vinegar, and synthetic additives like benzoates and sulfites.


Explain why traditional methods of preserving food such as candying fruits and salting meats worked to some degree?

Candying fruits and salting meats worked to preserve food because sugar and salt help create an environment that is inhospitable to bacteria and inhibits their growth. Sugar draws out water from fruits, making it difficult for bacteria to survive, while salt dehydrates meats and creates a high-salt environment that hinders bacterial growth. Additionally, sugar and salt were used in high concentrations, further aiding in preservation.
