Report the average time of 3 complete digestions. 7 Marking 7.1 General Rules Symbols that satisfy the requirements in 7.2 and 7.3, and stipulations in YY/T 0466.1 can be adopted. 7.2 Individual Packaging a) Name and specification of contents; b) Sterile and sterilization mode; c) Information like one-time use only and prohibited use after package damage; d) Expiration date; e) Name and address of manufacturer; f) Batch number or date of production. 7.3 Shelf Packaging Shelf packaging shall at least include the following information. a) Name and specification of contents; b) Sterile and sterilization mode; c) Information like one-time use only and prohibited use after package damage; d) Expiration date; e) Name and address of manufacturer; f) Batch number or date of production. 8 Packaging 8.1 Manufacturers shall be able to provide a certificate, proving the package that holds Appendix A (normative appendix) The Determination of Protein Content with Kjeldahl Method A.1 Principle Through the determination of total nitrogen content in the test sample and non-protein content in the sample filtrate, in which, protein is removed through the method of tungstic acid precipitation, calculate the protein content. A.2 Instruments and Equipment Analytical balance, azotometer, Kjeldahl tube, digestion furnace, fume cupboard or equivalent equipment. A.3 Chemical Reagents a) Concentrated sulfuric acid. analytical purity, relative density. 1.84. b) Digestive agent. weigh-take 10 g of copper sulfate (CuSO45H2O) and 100 g of potassium sulfate; place it in a mortar; porphyrize them together, then, mix them up. c) 50% sodium hydroxide solution. take 500 g of sodium hydroxide, place it in a volumetric flask; add distilled water to 1,000 mL; evenly shake it. d) Mixed indicator. mix 5 PCS of 0.2% bromocresol green ethanol solution and 2 PCS of 0.1% methyl red ethanol solution. e) 2% boric acid absorption liquid. weigh-take 20 g of boric acid, place it in a volumetric flask; add distilled water to dissolve it into 1,000 mL. Add 10 mL of d) mixed indicator; mix it up. f) Sulfuric acid titration solution [c(H2SO4) = 0.05 mol/L]. take 3 mL of sulfuric acid, slightly inject it into an appropriate amount of water; cool down to room temperature; add water to dilute to 1,000 mL, then, shake it up. Take around 0.15 g of benchmark anhydrous sodium carbonate that is dried to constant weight at 270 °C ~ 300 °C, weigh it accurately. Add 50 mL of water to dissolve it; add 10 drops of methyl red-bromocresol chlorine mixed indicator. Use sulfuric acid titration solution to titrate it, till the solution turns from green to purple red. Boil for 2 min; cool down to room temperature. Continue to titrate, till the solution turns from green to dark purple. Every 1 mL of sulfuric acid titration solution is equivalent to 5.30 mg of anhydrous sodium carbonate. In accordance with the consumption of sulfuric acid titration solution and the dosage of anhydrous brown bottle for storage. g) Sodium hydroxide solution [c(NaOH) = 6 mol/L]. weigh-take 24.0 g of sodium hydroxide; use water to dissolve and dilute to 100 mL. h) Hydrochloric acid solution [c(HCl) = 6 mol/L]. take 54 mL of hydrochloric acid; add water to dilute to 100 mL. i) Methyl red indicator. take 0.1 g of methyl red, then, add 7.4 mL of 0.05 mol/L sodium hydroxide solution to dissolve it.

Thus, obtain 1 mol/L hydrochloric acid solution. Take another 1 mL of 1 mol/L hydrochloric acid solution; add water to dilute to 1,000 mL. B.4 Test Methods B.4.1 Sample processing Take around 25 mg of collagen sponge sample, weigh it accurately; place it in a test tube (or an ampoule) with a plug. Add 4 mL of 6 mol/L hydrochloric acid solution; seal it up; place it in a drying oven at 110 °C, then, start hydrolysis for 24 h. Take it out, cool it down, then, open the sealing. Add 1 drop of methyl red indicator to make it red. Use 6 mol/L sodium hydroxide solution to neutralize it, till the solution turns yellowish. Add water to dilute to 250 mL, then, filter it. It shall work as sample test solution. B.4.2 Determination Take 0.5 mL of sample test solution, place it in a colorimetric tube with a plug, then, add 0.5 mL of water. It shall work as sample solution. Add 2 mL of isopropanol and 1 mL of oxidant solution; shake it up; place it at room temperature for 4 min, so that it can be oxidized. Add 2 mL of Ehrilich reagent, put on the plug, then, shake it up. Place it in water bath at 60 °C; heat it up. 20 min after color development, place it at room temperature for 1 h. Use a 1 cm colorimetric cuvette; determine absorbance at 560 nm. Use reagent for blank correction. B.5 Standard Curve Respectively take 0 mL, 0.2 mL, 0.4 mL, 0.6 mL, 0.8 mL, 1.0 mL of standard solution; add them to 6 colorimetric tubes (hydroxyproline content shall respectively be. 0 μg, 2 μg, 4 μg, 6 μg, 8 μg, 10 μg).
