Factors affecting the processing of freeze-dried strawberries

Hello, the factors that affect the processing of freeze-dried strawberries are temperature and time. When strawberries are pre-frozen, the central temperature of strawberries should be reduced to-18 ~-22℃ for 3.5 ~ 4.5 hours. The warming stage of strawberries, that is, the thawing stage of strawberries, also needs to adapt to the temperature of each stage and strictly control the time of each stage in order to achieve the effect of preservation. If the temperature changes too fast, it is easy to destroy the texture of strawberries and lose their original nutritional value.

I hope I can help you.
