Granule for detecting glucose in pet urine and method for preparing the same

A method for preparing granules for detecting glucose in pet urine, the method comprising:

• 1) weighing raw materials;
• the raw materials comprising between 80 and 100 weight parts of a filler, between 30 and 50 weight parts of a water-absorbent material, between 2 and 4 weight parts of a bacteriostatic agent, between 5 and 10 weight parts of an adhesive, between 1 and 2 weight parts of glucose oxidase, between 2 and 4 weight parts of peroxidase, and between 2 and 6 weight parts of an indicator;
• wherein:
• the filler is wood fiber, gelatinized starch, bentonite clay, charcoal of crop residue, acrylic fiber, polyacrylonitrile fiber, or a mixture thereof;
• the water-absorbent material is an acrylic-epoxy resin;
• the bacteriostatic agent is ethyl paraben, potassium sorbate, sodium benzoate, or a mixture thereof;
• the adhesive is styrene-butadiene rubber, polyurethane, cellulose nitrate, sodium carboxymethyl cellulose, polyvinyl alcohol, or a mixture thereof;
• and
• the indicator is a mixture of 4-aminoantipyrine and sodium 4-hydroxybenzoate at a weight ratio of 1:1;
• 2) pulverizing the filler, the water-absorbent material, the bacteriostatic agent, the glucose oxidase, the peroxidase, and the indicator;
• 3) mixing the filler, the water-absorbent material, the bacteriostatic agent, the glucose oxidase, the peroxidase, and the indicator obtained in 2) with the adhesive, and adding water to a resulting mixture to yield a mixed slurry, wherein an amount of the water is 0.4-0.6 times of a weight of the raw materials;
• 4) feeding the mixed slurry to a twin-screw extruder for granulation, to yield granules;
• and
• 5) drying the granules.
