How do salts and sugars work to preserve food?
Salts and sugars work to preserve food by creating an environment that is unfavorable for the growth of bacteria. They lower the water activity in the food, making it less hospitable for microbial growth. Salts work by drawing water out of bacteria, while sugars interfere with the bacteria's ability to reproduce.
Why is possible to preserve food by adding salt or sugar?
The addition of salt or sugar reduces the water that is available so that spoilage organisms won't grow.
What household materials can preserve food?
Examples: salt (sodium chloride), vinegar, sugar.
Why salt good for preserving food?

Which makes the best preservative vinegar salt garlic or sugar?
Salt is the best preservative among vinegar, salt, garlic, and sugar as it draws out moisture and inhibits the growth of bacteria, yeast, and mold. Sugar can also be an effective preservative by creating an environment where microorganisms cannot grow, but salt is more commonly used for preserving foods.
What are two natural food preservatives that most of us have in our kitchen cupboards?
Common preservatives used at home include salt, vinegar, and citrus juice.
How long does salt preserve food for?
Salt can preserve food for varying lengths of time, depending on factors such as the type of food and the amount of salt used.

Salt works by drawing out moisture from the food, creating an inhospitable environment for bacteria and other spoilage agents.
How do you use salt as a preservative?
Salt is used as a preservative by drawing out moisture from foods, which inhibits the growth of microorganisms that cause spoilage. It works by creating a high-salt environment that is inhospitable to bacteria, yeasts, and molds. Salt can be used to cure meats, preserve vegetables, and extend the shelf life of various food products.
How could salt take the place of a refrigerator?
Salt can be used to preserve food by drawing out moisture and creating an inhospitable environment for bacteria growth.

Why do you use salt and vinegar to preserve vegetables and fruits?
Salt and vinegar are used to preserve vegetables and fruits by creating an environment that inhibits the growth of harmful bacteria and mold. Salt draws out moisture, which helps slow down the spoilage process, while vinegar's acidity further inhibits microbial growth. This preservation technique has been used for centuries to extend the shelf life of fruits and vegetables.
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.
