säilitusmeetodeid
Säilitusmeetodid refers to various techniques used to preserve food and other perishable items, extending their shelf life and preventing spoilage. These methods work by inhibiting the growth of microorganisms, such as bacteria, yeasts, and molds, or by slowing down enzymatic activity that leads to degradation. Common methods include refrigeration, which slows down microbial growth and chemical reactions, and freezing, which stops microbial activity by turning water into ice.
Other prevalent techniques involve heat treatment, such as pasteurization and sterilization, which kill or inactivate microorganisms.
