Embodiment 1
[0040] Take fresh ginger to remove moldy parts and impurities, weigh 1000g, rinse, drain the surface water, extract 880g of ginger juice, let it stand, filter, discard the filter residue, put ginger juice in a reaction container, add solid reagent cornstarch and α-cyclodextrin, the weight ratio of the two is 30:70, a total of 35g, carry out liquid-solid extraction under electromagnetic stirring, control the heating temperature at 40°C, continue stirring and extracting for 8h, let stand for 12h, discard most of the supernatant, filter , to obtain a filter cake, put the filter cake in an oven to dry at 60° C., weigh, pulverize, pass through an 80-mesh sieve, inspect, and pack to obtain 6.3 g of the product. This product is a light yellow powder with a peculiar aroma and a spicy taste.
