Zusammenfassung:	The invention relates to a fresh-keeping method of toona sinensis sprouts based on ice-temperature storage. The fresh-keeping method comprises the following steps of (1) collecting toona sinensis sprouts; (2) performing fresh keeping with a biological fresh-keeping agent and performing precooling; (3) performing spontaneous air-conditioning fresh-keeping packaging; (4) determining the temperature of ice temperature; and (5) performing ice-temperature preservation. According to the fresh-keeping method disclosed by the invention, internal nutrient components and external organoleptic quality of the toona sinensis sprouts are maintained to the great extent, and the breathe intensity and the lipid peroxidation degree of the toona sinensis sprouts are reduced. Besides, the activity of polyphenol oxidase PPO is restrained, the shelf life can be prolonged to about 40 days, and the purposes of storage and fresh keeping are achieved. The fresh-keeping technology is simple, convenient to operate, easy to implement, lo
