Embodiment 1
[0041] The mensuration of acid detergent fiber content in embodiment 1, alfalfa
[0042] (1) Alfalfa is air-dried, and then ground to a particle size of 18 meshes with a food grinder.
[0043] (2) Put 1.03 g of the above-mentioned alfalfa and 20 mL of acid washing solution into a preservation bottle (capacity 225 mL), seal it with plastic wrap, and place it in a microwave oven for degassing until it boils until the bottle mouth stops heating. Then add 20mL of acid washing solution in four times, repeat the above degassing process, and add 100mL of acid washing solution in total; during the above degassing process, the power of the microwave oven is 500W, and the degassing time is 1min.
[0044] (3) Add 100mL of acid washing solution to the above-mentioned storage bottle, seal it with a plastic film in a pressure cooker, cap and tighten it, and add it to the neck of the bottle. The pressure cooker is covered and kept pressurized for 30 minutes, and the pressure is 150kpa. of t...
