Values are means±standard errors of five replicates.
Means in a column with different lower case letters or in the same raw for same type of samples with different upper case letters were significantly different by Duncan's multiple rage test, p<0.05. Lower case letters relate to comparisons of the influence of different storage temperature and package within each storage day. Upper case letters relate to comparison of the effect of storage days, within each treatment.
NS,*,**, *** : no significant or significant at p<0.05, 0.01, or 0.001 respectively.
