Abstract

The invention discloses a peach preservative which is a mixed solution prepared by blending citric acid, calcium chloride and ascorbic acid, wherein mass concentration of citric acid is 1-2 g / ml, mass concentration of calcium chloride is 2-4 g / ml and mass concentration of ascorbic acid is 0.02-0.1 g / ml. The invention also discloses a peach preservation method which comprises the following steps: harvesting normally-developed peach fruits with no mechanical damage or insect diseases in the maturity period of peaches; putting the harvested peach fruits into a refrigeration house to be precooled to 2-4 DEG C; putting the precooled peach fruits into the peach preservative as mentioned in the claim 1 to be immersed for 5-10 min, and naturally airing the peach fruits; and packaging the peaches processed with the peach preservative with foam mesh bags, and putting the packaged peaches into carton boxes to be ready for transport. The mixed solution prepared by blending of citric acid, calcium chloride and ascorbic acid is used as the peach preservative, and citric acid, calcium chloride and ascorbic acid can together maintain hardness and flavor of peach flesh, inhibit after-ripening and prevent deterioration of the fruits.
