Embodiment 1
[0030] A method for detecting microcrystalline cellulose content in collagen casings, comprising the following steps:
[0031] (1) Cut the collagen sausage casing into the Erlenmeyer flask, record the casing weight M1; add 10wt% hydrochloric acid and collagen proteolytic enzyme, put a funnel on the Erlenmeyer flask, and heat in a water bath at 75°C for 1 hour;
[0032] Then dip a small amount of solution and observe under the microscope whether the digestion is complete, and the cellulose is completely exposed as the digestion is complete;
[0033] The volume-to-mass ratio of the hydrochloric acid to the collagen casing is 5mL:2g.
[0034] The dosage of collagen proteolytic enzyme is 0.16%, and the dosage of 10% hydrochloric acid is 5mL.
[0035] (2) Pour the digested solution into a centrifuge tube, and centrifuge at 3500rpm for 25 minutes; too much solution cannot be loaded at one time, centrifuge in several times, pour out the supernatant after each centrifugation, and the...
Embodiment 2
[0039] A method for detecting microcrystalline cellulose content in collagen casings, comprising the following steps:
[0040] (1) Cut the collagen casing into the Erlenmeyer flask, record the casing weight M1; add 10wt% hydrochloric acid and collagen proteolytic enzyme, put a funnel on the Erlenmeyer flask, and heat in a water bath at 80°C for 3 hours;
[0041] Then dip a small amount of solution and observe under the microscope whether the digestion is complete, and the cellulose is completely exposed as the digestion is complete;
[0042] The volume-to-mass ratio of the hydrochloric acid to the collagen casing is 5mL:2g.
[0043] The dosage of collagen proteolytic enzyme is 0.16%, and the dosage of 10% hydrochloric acid is 5mL.
[0044] (2) Pour the fully digested digestion solution into a centrifuge tube and centrifuge at 4000rpm for 30 minutes; too much solution cannot be loaded at one time, centrifuge in several times, pour out the supernatant after each centrifugation,...
Embodiment 3
[0048] A method for detecting microcrystalline cellulose content in collagen casings, comprising the following steps:
[0049] (1) Cut the collagen sausage casing into the Erlenmeyer flask, record the casing weight M1; add 10wt% hydrochloric acid and collagen proteolytic enzyme, put a funnel on the Erlenmeyer flask, and heat in a water bath at 85°C for 4 hours;
[0050] Then dip a small amount of solution and observe under the microscope whether the digestion is complete, and the cellulose is completely exposed as the digestion is complete;
[0051] The volume-to-mass ratio of the hydrochloric acid to the collagen casing is 5mL:2g.
[0052] The dosage of collagen proteolytic enzyme is 0.16%, and the dosage of 10% hydrochloric acid is 5mL.
[0053] (2) Pour the fully digested digestion solution into a centrifuge tube and centrifuge at 4500rpm for 35 minutes; too much solution cannot be loaded at one time, centrifuge in several times, pour out the supernatant after each centrif...
