The invention discloses an optimized formula and a processing method of lotus leaf ferment. The optimized formula comprises the following components: lotus leaves, white granulated sugar, saccharomycetes and purified water, wherein based on the difference between fresh lotus leaves and dried lotus leaves, the optimized formula is divided into different optimized formulas. The formula of the lotusleaf ferment provided by the invention has sanitation, safety, clarity, transparency, refreshing taste, rich nutrients, short fermentation time and special fragrant smell of the lotus leaves; comparedwith a traditional formula, the acidity, sweetness, taste, smell, color, texture state and other sensory evaluations of the optimized formula of the lotus leaf ferment are all obviously improved; thepurposes of improving the utilization ratio of the lotus leaves and increasing the activity of the ferment are achieved; and the requirements of modern people on diversity, balance and absorbabilityof food nutrients are met.
