- Abstract
The drying of fruits such as freeze-dried strawberries is an alternative to increase the added value of fresh strawberries, extend shelf life, have properties like fresh fruit, and have made it possible for consumers to be able to consume during all seasons. This study was aimed at examining the chemical quality of freeze-dried strawberries. Freeze-dried strawberries were made using a combination of pre-treatment by osmotic dehydration (OD) with the freeze-drying method. The combination of treatment materials and freeze-dried strawberries production processes used were the duration of storage in the freezer (4, 14, and 21 d), concentrate osmotic agents with (40, 50, and 60°Brix); splitting (vertically cuts strawberry) time (early, before OD, and after OD); immersion time for 120 min, and freeze-drying time of 24 h. The research chemical quality parameters of freeze-dried strawberries were water content, vitamin C, total phenolic content, total acid, and total soluble solids. The result showed that the lowest of water content (2.164%) and total acid (0.072%) then the highest of vitamin C (152.241 mg/100 g), total phenolic content (1.672%), and total soluble solids (22.333°Brix) were at the duration of storage in freezer 4 d, concentrate agents with 60°Brix, and splitting time before OD. Statistical testing showed that there was no significant difference (sig < 0.05) in all the parameters tested.
