The invention discloses a low-energy health chocolate and an industrial production method thereof. The chocolate comprises the following materials by weight percent: 5-10 percent of flavor component, 8-10 percent of cocoa butter, 20-30 percent of low-energy cocoa butter, 40-50 percent of low-energy sweetener, 0.5-1.0 percent of emulsifying agent and 3-10 percent of no-energy filling agent; the low-energy cocoa butter can be prepared by the following method: under the condition of 60-80 DEG C, adding caprylic acid or decylic acid and behenic acid into the cocoa butter, adding lipase with the mass equal to that of total substrate, under the stirring speed of 100-200r/min, reacting for 6-12 hours under the action of enzymatic and catalytic ester exchange, filtering to remove enzyme and obtain crude oil, and carrying out molecular distillation, refining and deacidification on the crude oil to obtain the low-energy cocoa butter; and the preparation method comprises the steps of mixing, accurate grinding, refining, temperature adjusting, forming and the like. The low-energy health chocolate realizes sugar free, low sweetness, high fibrosis and low energy.
