摘要

Effects of different plant extracts on quality and shelf-life of coated fish balls during frozen storage were investigated. Fish balls were coated with thyme (TE) and green tea (GE) extracts in sodium alginate solution at levels of 0.4 and 0.6%, respectively, and stored at --13 +or- 1 degrees C for 120 days. The control group and the coated fish balls were analysed periodically for storage stability, colour and sensory properties. For raw fish balls, highest storage stability was demonstrated by samples coated with 0.4% TE and 0.6% GE. Highest mean L values were found in samples coated with 0.4% TE and controls, while the lowest b values were observed in samples coated with 0.4% TE, 0.4% GE and controls. Sensory scores for all fried samples were acceptable during frozen storage. Results indicate that use of appropriate levels of plant extracts may be advantageous in edible coating processes.
