Problems solved by technology

[0005] At present, the quality evaluation of the color of rubber products is still based on subjective judgments, relying entirely on the experience of workers’ naked eye observation, which is highly subjective and cannot be quantified, and it is difficult to control the consistency of the appearance quality of rubber products
Gel strength is the inherent quality of animal glue products. Gel strength is generally measured by texture analyzers and physical property analyzers. However, these methods take a long time to test, and the production process in the control workshop is lagging behind. Animal glue needs to be checked during the production process. Accurately and quickly grasp the quality of similar products

Embodiment 1

[0015] In the process of gelatin gelatin concentration and gelatinization, after the auxiliary materials—rice wine, rock sugar, and soybean oil are added, adjust the pressure of the steam to control the gelation time within 1, 2, 3, 4, 5, and 6 hours, and control the moisture content. Between 25-26%, take a sample, place it in a transparent vessel, and measure it. Set up and calibrate the colorimeter before measuring the color of the glue: first turn on the power of the colorimeter, select the D65 light source, and select the CIE Lab and CIE1967Eab modes for the color space and index; according to the CIE standard, the observer angle is 10°, and the sample average is set The number of measurements is 3, and then the black and white plate calibration is performed. After the instrument is calibrated, the container containing the glue solution is placed in the measurement port for measurement. The color difference results are shown in Table 1.

[0029] In the process of concentrating the tortoise shell glue, after the auxiliary materials—rice wine, rock sugar, and soybean oil are added, adjust the pressure of the steam to control the glue out time within 1, 2, 3, 4, 5, and 6 hours. Between 22-23%, take a sample, place it in a transparent vessel, and measure it. Set up and calibrate the colorimeter before measuring the color of the glue: first turn on the power of the colorimeter, select the D65 light source, and select the CIE Lab and CIE1967Eab modes for the color space and index; according to the CIE standard, the observer angle is 10°, and the sample average The number of measurements is 3, and then the black and white plate calibration is performed. After the instrument is calibrated, the container containing the glue solution is placed in the measurement port for measurement. The color difference results are shown in Table 3.

Abstract

The invention relates to a method for rapidly controlling the quality of animal glue products. The method comprises the following steps: sampling when the moisture content of the selected glue solution is 22-26% in the process of concentration to output glue, measuring values L*, a* and b* of glue color by a colorimeter, and evaluating the bloom strength of glue solution by the values L*, a* and b*, wherein when the value L* is 17.56 to 25.13, the value a* is 6.06 to 13.14, the value b* is 14.98 to 22.46, and the corresponding bloom strength of glue solution is 290-370 Bloomg, the obtained animal glue products has better quality. According to the method for rapidly controlling the quality of animal glue products, the change trend of the bloom strength is evaluated by measuring the color of glue solution, the production process can be controlled rapidly and conveniently, the quality of products is ensured, the subjectivity of sensory evaluation is overcome, and a quantitative basis is provided for rapidly controlling the appearance and inherent quality of animal glue products.

Description

technical field [0001] The invention relates to a method for controlling the quality of animal glue products, in particular to a method for better controlling the quality of such products by quantitatively analyzing the color of the product and indirectly measuring the change trend of its gel strength. Background technique [0002] Animal glue products have good medicinal value and health value. The production process of animal glue products needs to go through many processes, mainly including processes such as glue melting, filtration, evaporation, concentration and drying, and glue drying. Among them, the concentration of glue is the key process that affects the color and gel strength of the finished glue. Color and gel strength are the main indicators for quality control of this type of product. [0003] Gum traditional Chinese medicine is concentrated to a certain extent, and excipients such as rice wine, soybean oil, and rock sugar need to be added. As the heating time...
