The invention provides hydrogen-rich black date juice, hydrogen-rich black date wine and preparation methods thereof. The obtained hydrogen-rich black date juice and hydrogen-rich black date wine contain rich hydrogen, the hydrogen is mixed with black date juice or black date wine in a supercritical state, the density of the hydrogen in the supercritical state is increased from original 0.0899 g/L to 0.5-0.8 g/L, and the solubility of the hydrogen in the black date juice and the black date wine is increased. The hydrogen has selective free radical removing capacity at the addition concentration and content, and the content of cyclic adenosine monophosphate in the black date wine is 10%-20% higher than that when the hydrogen is not added; the content of vitamin C is 5%-15% higher; the content of 5-hydroxymethylfural is 20%-25% higher and the content of polyphenols is 10%-15% higher. In combination with the characteristic functions of the hydrogen, the functions of the prepared black date juice and black date wine are greatly improved.
