A kind of donkey-hide gelatin sensory quality evaluation method

Abstract

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.

Description

technical field [0001] The present invention relates to the field of sensory quality evaluation of donkey-hide gelatin, in particular, relates to a method for measuring sensory indicators such as color, smell, texture and appearance of donkey-hide gelatin, and using these sensory indicators to calculate comprehensive sensory equivalent values ​​to evaluate the sensory quality of donkey-hide gelatin. method of evaluation. Background technique [0002] For the evaluation of the intrinsic quality of donkey-hide gelatin, there are detailed standards and evaluation methods in the 2015 edition of the Chinese Pharmacopoeia, which can objectively and fairly evaluate the intrinsic quality attributes of donkey-hide gelatin. But, for the evaluation of the sensory quality of donkey-hide gelatin, there is no definite evaluation method and standard at present, [0003] The sensory quality of donkey-hide gelatin refers to the color, appearance and shape felt by human vision, the smell qua...

Problems solved by technology

[0005] At present, the commonly used detection method for color is the colorimeter. For the color detection of donkey-hide gelatin, the method of using the colorimeter to measure the color in the production process is provided in the patent "Quick Control Method for the Quality of Animal Glue Products" (Application No.: 201410835518.7) , but the method disclosed in this patent is a method for measuring the color of donkey-hide gelatin in a liquid state during the production process. It does not provide a method for measuring the finished solid donkey-hide gelatin block, nor does it specify the basis and method for the classification of donkey-hide gelatin
