| Abstract: |
| In this paper，the freezing rule of banana after the pretreatment of compound color fixative and
blanching were studied respectively in freezing temperature，-15，-25，-35，-45，-55 and -70℃. With the
freezing temperature decreasing，the sugar content and soluble solid content of banana stayed unchanged，the
color L value raised basically. The pH，weight loss，juice leakage and electrical conductivity of banana declined
gradually. Generally，the quality of freezing bananas was close at -45℃，-55℃ and -70℃ freezing. Considering
the costs，it was better to choose -45℃ freezing. With the storage time increasing，the quality of frozen bananas
decreased gradually，and the quality was great at -28℃ storage. Thus -45℃ freezing and -28℃ storage was
selected as banana freezing process parameters. Frozen bananas can be stored for at least 60 days under these
conditions. |
