The invention discloses an evaluation method of the sensory quality of ass-hide glue. The method comprises the following steps: S1, electing one ass-hide glue in the same batch of ass-hide glue as an ass-hide glue sample; S2, measuring the magnitude V1 of the color index of ass-hide glue sample, the magnitude V2 of the flavor component content of odor, the gel intensity magnitude V3 of texture, and the difference values V4, V5 and V6 between the length, the width and the thickness of the ass-hide glue sample and a standard length, a standard width and a standard thickness; S3, respectively computing the color equivalent value U1, the odor equivalent value U2, the texture equivalent value U3 and the shape equivalent value U4 of ass-hide glue according to all data measured in the step S2; S4, computing the sensory quality equivalent value SEQV of ass-hide glue according to the color equivalent value U1, the odor equivalent value U2, the texture equivalent value U3 and the shape equivalent value U4 obtained in the step S3; S5, comparing the measured sensory quality equivalent value SEQV of ass-hide glue with a sensory quality classification table of ass-hide glue, so as to obtain a corresponding sensory quality grade of ass-hide glue.
