Embodiment 1
[0050] (1) 500 grams of peanut shells are placed in a pulverizer to pulverize, and sieved with sieves with apertures of 4 mm and 6 mm respectively to obtain peanut shells with a particle size of 4 to 6 mm;
[0051] (2) Wash 75 grams of peanut shells obtained by step (1) with 420mL of deionized water and soak in 420mL of absolute ethanol for 1 hour, remove the liquid after filtration to obtain substance P, after substance P is washed with 350mL of deionized water To obtain substance P1, put substance P1 into 420mL of NaOH solution with a molar concentration of 3.3mol / L and soak for 1 hour, remove the liquid after filtration to obtain substance P2, and obtain substance P3 after substance P2 is washed with 450mL deionized water. Substance Q was obtained after being placed in a drying oven at 45°C for 24 hours;
[0052] (3) 10.99 grams of methyl sorbate are added to 1000 mL of ethanol solution with a mass percentage concentration of 25%, stirred for 3 minutes at 1000 r / min, shaken...
