Effects of Frozen Storage Time on the Functional Properties of Frozen Wheat Gluten

摘要

The effects of frozen storage time on the functional properties of frozen wheat gluten were evaluated. The frozen wheat gluten was subjected to frozen storage in refrigerator at-18°C for 0-120days. The samples were obtained by the process of freeze-drying. The main functional properties of frozen wheat gluten were determined to confirm the effects of frozen storage time on functional properties of frozen wheat gluten. Results showed that solubility, water-holding capacity, emulsifying capacity, foamability and foam stability of frozen wheat gluten decreased and that oil-holding capacity, emulsion stability of frozen wheat gluten were improved with prolonged frozen storage time.
