Answer 1

To preserve the food material Formalin is used.

Why formalin is used for preservation?

Formalin is a formaldehyde solution with a concentration of 40%. Because it is a disinfectant, germicide, and antiseptic, it is used to preserve biological material. It keeps the specimens from degrading due to bacterial development.

How can we preserve food materials:

• For millennia, salt, sodium nitrite, spices, vinegar, and alcohol have been used to preserve food. To reduce microbial development that leads to spoilage and to slow changes in colour, texture, and flavour, sodium benzoate, calcium propionate, and potassium sorbate are utilised.

• Extra-virgin olive oil is a natural preservative that protects food from spoiling by isolating it from the air and creating a barrier that inhibits oxidation and mould. It's used to keep herbs, vegetables, and fish fresh.
