Abstract

The invention relates to the technical field of glue quality analysis, in particular to a glue quality monitoring method based on turbidity analysis. The method comprises the following steps of firstly, preparing and diluting a glue or a glue intermediate product into a glue solution, representing the concentration of the glue solution by using the refractive index (brix degree) of the glue solution, and determining the concentration of the glue solution by adopting a refraction method; diluting the glue solution to a specific concentration according to the concentration measured by a refraction method; determining the turbidity of the to-be-detected glue solution with the specific concentration by using a turbidity meter; and judging the glue quality in the production process according to the refractive index and the turbidity value. The testing principle is reasonable, the concentration of the glue solution is measured by the refraction method, and the linear relation is good through verification of a gravimetric method; according to the optical characteristics of the impurities, the turbidity of the glue solution with specific concentration is used for representing the water-insoluble impurities in the glue solution, so that the actual condition of the water-insoluble impurities can be better represented; the operation is simple, the analysis efficiency is high, and the refraction method for determining the concentration of the glue solution has the characteristics of rapidness, simplicity and convenience.

Description

Technical field [0001] The present invention relates to the field of animal glue mass analysis, and more particularly to an inclusion production quality monitoring method based on turbidity analysis. Background technique [0002] The information disclosed in the background is disclosed only to increase the understanding of the overall background of the present invention, and is not necessarily considered to admit or imply that the information is intended to be a prior art known to those skilled in the art. [0003] The rubber is referred to as a solid bulk oral formulation, a solid bulk coat formulation, such as gelatin, Huang Minggue, deer rubber, antlers, and olee, and deer rubber, deer rubber, antler. The 2020 edition "China Pharmacopoeia" general -0184 inclusion, "said inclusions should be uniform in color, no abnormal odor. It should be no different from the dissolved in hot water." As an example of gelatin, Ejiao is For the raw material, it is concentrated by a cooking. Eji...
