When eating lotus seeds, I feel bitter because the turquoise germ in the middle of lotus seeds is not completely removed. This turquoise germ is the common lotus plumule. Plumula Nelumbinis mainly contains liensinine, isoliensinine, methylliensinine, preliensinine, plumula Nelumbinis, buffalo horn, corydalis methyl, northeophylline and brass such as luteolin, hyperoside and rutin. Among them, protonuciferine, cornucopia and methyl corydalis tuber are bitter, so lotus plumule is bitter, and mature lotus plumule will also be bitter.
Method for removing lotus plumule
(1) Fresh lotus seeds are pitted.
Fresh lotus seeds can be peeled off directly by hand and the lotus seed core can be taken out. You can also directly push the lotus plumule out from the bottom of the lotus seed with a toothpick, so as to keep the appearance of the lotus seed intact.
(2) removing the core of the dried lotus seeds
You can choose to remove the lotus plumule with a knife, but the dried lotus seeds need to be soaked in water first, and then draw a circle horizontally in the middle of the lotus seeds with a knife to break the shell of the lotus seeds and take out the whole lotus seeds. Then put a toothpick through the lotus seeds, take out the lotus plumule and pull it out by hand.
