Different storage temperatures and different application ranges.

1. Storage temperature: Refrigerated crab paste is a medium-temperature storage, between 5 degrees Celsius and 10 degrees Celsius, while frozen crab paste is a low-temperature storage, at minus 18 degrees Celsius or lower.

2. Scope of application: Because of different temperatures, each is suitable for different types of food. Refrigeration is usually suitable for preserving perishable foods, fruits, vegetables, etc., which need to be consumed within a short period of time. In contrast, freezing can better preserve some foods that do not need to be eaten immediately, such as meat, seafood, etc., because they can be taken out and used at the appropriate time.
