Abstract

The invention relates to a preservation method of pitaya fruit. The preservation method specially comprises the following steps: harvesting the pitaya fruits, and then, carrying out washing, sterilizing, preservative-solution soaking and packing. The preservation method of pitaya fruit disclosed by the invention is capable of obviously inhibiting yellowing of peels and rot of the pitaya fruits while reducing water loss; at the same time, the preservation method inhibits microbial breeding so as to prevent the pitaya fruits from turning putrid, so that relatively high fruit rigidity and Vc content are preserved. The preservation method of pitaya fruit disclosed by the invention is safe and environment-friendly. The preservation method is capable of effectively prolonging post-harvest lives of the pitaya fruits during normal-temperature storage and transportation. Stored and preserved by the preservation method of pitaya fruit disclosed by the invention, the fresh pitaya fruits maintain the original qualities after 18 days of storage and the marketable fruit rate is up to higher than 92%.
