The invention discloses a refrigerating preservation method of fresh lotus seedpods. The method includes the following steps of 1, low-temperature cleaning of fresh-picked lotus seedpods; 2, low-temperature soaking and ozone water sterilization; 3, composite color-protecting preservative film formation treatment; 4, polypropylene preservation bag packaging, and conduction of low-temperature refrigeration at the temperature of 0-2 DEG C to obtain finished products. According to the method, microorganisms on the surfaces of the lotus seedpods can be effectively restrained or killed, photosynthesis, respiration, rising, glycometabolism and other physiological metabolism activities of the fresh lotus seedpods are retarded, and ethylene release and chlorophyll degradation can be restrained; color browning of the fresh lotus seedpods in the storage period is retarded, the appearance quality of the fresh lotus seedpods is fully reserved, and the nutritional quality and flavor of lotus seeds are well kept; the effective length for preservation of the fresh lotus seedpods can be kept for as long as 50 days through the preservation method. The method is simple and easy to carry out, high in operability, low in energy consumption cost and free of excessive investment, the process is environment-friendly, safe and free of pollution, the obtained products are practical and convenient to eat, the shelf life of the fresh lotus seedpods is greatly prolonged, and a new way is developed for high-value utilization of the lotus seed products.
