Embodiment 1
[0026] A preparation method of an edible pet toy, comprising the following steps:
[0027] (1) Preparation of dilute alkali solution: prepare Na with a mass concentration of 25% 2 CO 3 0.8L of dilute solution, 1.6L of NaOH dilute solution with a mass concentration of 20%, mix well at a ratio of 1:2 for later use;
[0028] (2) Preparation of carboxymethyl konjac glucomannan-based samples: Take 28g of konjac glucomannan and put it in a 2L beaker. Stir and mix for 1.5h under a fast stirrer for 1.5h, then add 200-300ml of monochloroacetic acid solution with a volume concentration of 30%, place it in a constant temperature water bath at 60°C, and stir rapidly at a speed of 1200r / min for 5h, and then use 1mol / L hydrochloric acid to adjust the pH value to 7.2, then precipitate with a mixed solution of methanol and ethanol with a volume ratio of 2:1, centrifuge at 6000r / min for 20min, wash the precipitate twice with 70% methanol, and dry That is, carboxymethyl konjac glucomann...
