Embodiment 1
[0013] According to the following steps, the vanilla spice product is prepared in two stages:
[0014] ①Weigh 500g of vanilla beans, cut them into small pieces of about 1-2cm, add 2000g of petroleum ether, and reflux extraction for 3 times, each time for 3 hours;
[0015] ② After drying the vanilla beans extracted with petroleum ether in the first paragraph to remove the residual petroleum ether, add 2500g of 70% ethanol each time, reflux extraction twice, each time for 3 hours, combine the extracts, and wait for them to settle naturally Suction filtration is then carried out, and the filtrate is concentrated under reduced pressure to obtain the vanilla spice product.
Embodiment 2
[0017] According to the following steps, the vanilla spice product is prepared in two stages:
[0018] ① Weigh 500g of vanilla beans, cut them into small pieces of 1-2cm, add 3000g of ethyl acetate, and reflux extraction for 3 times, each time for 2 hours;
[0019] ② After drying the above-mentioned vanilla beans extracted with ethyl acetate to remove residual ethyl acetate, add 3500g of 70% propylene glycol each time, reflux extraction twice, each time for 3 hours, combine the extracts, and wait for them to settle naturally Suction filtration is then carried out, and the filtrate is concentrated under reduced pressure to obtain the vanilla spice product.
