Summary
The purpose of this study is to find the optimum way in freezing Aster scaber so that it can be stored safely for a long time. The quality characteristics of Aster scaber dependent on cryoprotectants addition after blanching at 90°C for 3 minutes which had been set up by an advance experiment were evaluated. The L and b value of Aster scaber after they had been thawed from frozen status were significantly high and the original green colors were deepest; when Aster scaber had been treated with 1% salt or 0.1% polyphosphate, respectively. 99% or more of peroxidase was inactivated before and after the freezing. Sensory characteristics were done by traditional cooking method. The results showed that Aster scaber with 1% salt added was best with 6.00 points. Therefore, the most optimum way to freeze Aster scaber is adding 1% salt and blanching it for 3 minutes at 90°C.
