[0027] According to the mass ratio of 1:2, weigh celery and winter bamboo shoots respectively, put them into a juicer and squeeze the juice for 5 minutes, filter after squeezing the juice, collect the celery dregs and winter bamboo shoots dregs, and mix them to obtain a mixed residue. The residue was soaked in 0.1% sodium sulfite solution for 40 minutes and then filtered to obtain the filter residue. The filter residue was washed 3 times with deionized water. After washing, it was placed in a vacuum drying oven and dried at 70°C for 10 hours. After drying, it was put into a pulverizer for crushing , and passed through a 120-mesh sieve to obtain a mixed powder; weigh 3g of sodium alginate and add it to a 1000mL three-necked flask, and add deionized water 100 times the quality of sodium alginate to the three-necked flask, and stir until the sodium alginate dissolves to obtain alginic acid Sodium solution, add 20% sodium alginate solution mass mixed powder to the sodium alginate s...
