Sokerikerros

Sokerikerros, also known as sugar crust or sugar bloom, is a common issue in the storage and handling of certain foods, particularly fruits and vegetables. It occurs when the natural sugars in the produce crystallize on the surface, forming a hard, white layer. This phenomenon is often seen in fruits like apples, pears, and citrus, as well as in vegetables such as potatoes and carrots.

The formation of sokerikerros is influenced by several factors, including temperature, humidity, and the presence of certain compounds in the produce. High humidity and low temperatures can cause the sugars to crystallize more rapidly. Additionally, the presence of pectin, a natural substance found in fruits and vegetables, can facilitate the formation of sugar crystals.

Sokerikerros can affect the appearance and texture of food, making it less appealing to consumers. It can also pose a potential health risk, as the sugar crystals may harbor bacteria or other microorganisms. To prevent sokerikerros, it is recommended to store fruits and vegetables at appropriate temperatures and humidity levels, and to handle them gently to avoid bruising and subsequent sugar crystallization.
