Numerical values in bold text indicate that the score of the food on the top row of the table was significantly (P<0.000378) greater than the score of the food on the left column; Values in italicised text indicate that the score of the food on the left column of the table was significantly (P<0.000378) greater than the score of the food on the top row. Standard text indicates no significant difference (P>0.000378; the P-value was adjusted from 0.05 using the Bonferroni correction).
