the snail meat was subjected to sensory testing, and 50 persons were randomly selected, and the criteria for sensory evaluation are shown in table 1:
the escargots prepared through the three examples and the four comparative examples were scored according to the sensory evaluation criteria, and the results are shown in table 2:
