Embodiment 1
[0040] This example proposes a compound extract, calculated by mass percentage, including 70% mulberry leaf extract, 10% bitter melon extract, 10% raspberry tea extract, 5% guava leaf extract, and 5% mugwort extract .
[0041]The mulberry leaf extract or the bitter gourd extract is prepared by the following steps: pulverizing the mulberry leaf or the bitter gourd raw material respectively, passing through a 60-mesh sieve, mixing with water at a mass ratio of 1:20, and denaturing it at 90° C. for 24 hours Then, adjust the pH to 6 with hydrochloric acid, adjust the temperature to 50°C, then add pectinase with a mass of 1% of the mass of the raw material, carry out an enzymatic hydrolysis for 6 hours, and then inactivate the enzyme at 90°C for 15 minutes to obtain an enzymatic hydrolyzate. ;
[0042] The pH of the primary enzymatic hydrolyzate was adjusted to 8 with sodium hydroxide, and then the temperature was adjusted to 60° C. Papain was added with 3% of the raw material mas...
Embodiment 2
[0049] This example proposes a compound extract, calculated by mass percentage, including 60% mulberry leaf extract, 25% balsam pear extract, 5% raspberry tea extract, 5% guava leaf extract, and 5% mugwort extract .
[0050] The mulberry leaf extract or the bitter melon extract is prepared by the following steps:
[0051] The raw materials of mulberry leaves or bitter gourd were pulverized respectively, passed through an 80-mesh sieve, then mixed with water according to a mass ratio of 1:10, and denatured at 100 °C for 4 hours; then, the pH was adjusted to 6 with hydrochloric acid or phosphoric acid, and the temperature was adjusted to 45 °C, then Cellulase with a mass of 3% of the raw material mass was added to carry out an enzymatic hydrolysis for 1 hour, and then the enzyme was inactivated at 90° C. for 15 min to obtain an enzymatic hydrolysis product;
[0052] Adjust the pH of the primary enzymatic hydrolyzate to 7 with calcium hydroxide, then adjust the temperature to 45...
Embodiment 3
[0059] This example proposes a compound extract, calculated by mass percentage, including 60% mulberry leaf extract, 20% bitter melon extract, 10% raspberry tea extract, 5% guava leaf extract, and 5% mugwort extract .
[0060] The mulberry leaf extract or the bitter melon extract is prepared by the following steps:
[0061] The raw materials of mulberry leaves or bitter gourd were pulverized respectively, passed through a 60-mesh sieve, then mixed with water in a mass ratio of 1:40, and denatured at 90 °C for 12 hours; then, the pH was adjusted to 7 with hydrochloric acid, and the temperature was adjusted to 50 °C, and then the mass was added. Enzymatic hydrolysis was performed for 5% of the mass of the raw material β-glucanase for 6 hours, and then the enzyme was inactivated at 95° C. for 20 minutes to obtain an enzymatic hydrolysate;
[0062] The pH of the primary enzymatic hydrolyzate was adjusted to 10 with sodium hydroxide, and then the temperature was adjusted to 70 °C,...
