Embodiment 1
[0013] Harvest the bitter grass, wash it with tap water, dry it, put the cleaned bitter grass in a grinder, and grind it into particles with a particle size of 20 to 100 mesh;
[0014] 5g of crushed Herba galerygium was mixed with 50mL concentration of 1% AlCl 3 The aqueous solution is mixed, the pH value is adjusted to 4-6, heated to 120°C in a stainless steel reactor, reacted for 1 hour, cooled, and filtered to obtain the fermented sugar liquid of the bitter grass biomass; the fermented sugar content is determined by the DNS colorimetric sugar method, and The calculated sugar yield was 38%.
Embodiment 2
[0016] Harvest the bitter grass, wash it with tap water, dry it, put the cleaned bitter grass in a grinder, and grind it into particles with a particle size of 20 to 100 mesh;
[0017] Mix 5 g of crushed Herba balsam with 250 mL of 5% CuCl 2 The aqueous solution is mixed, the pH value is adjusted to 4-6, heated to 180°C in a stainless steel reactor, reacted for 4 hours, cooled, and filtered to obtain the fermented sugar liquid of the bitter grass biomass; the fermented sugar content is determined by the DNS colorimetric sugar method, and The calculated sugar yield was 78%.
Embodiment 3
[0019] Harvest the bitter grass, wash it with tap water, dry it, put the cleaned bitter grass in a grinder, and grind it into particles with a particle size of 20 to 100 mesh;
[0020] 5g of crushed Herba galerygium was mixed with 200mL concentration of 3% NiCl 2 The aqueous solution is mixed, the pH value is adjusted to 4-6, heated to 160°C in a stainless steel reactor, reacted for 6 hours, cooled, and filtered to obtain the fermented sugar liquid of the bitter grass biomass; the fermented sugar content is determined by the DNS colorimetric sugar method, and The calculated sugar yield was 85%.
