At present, it is during the citrus harvest season that how to do a good job of keeping fresh oranges and prolonging the sales time in order to sell a good price is the wish of the orange farmers. Some areas in Hunan have explored a low-cost, but effective way. According to Dai Tiesheng, a seed company of Qidong County, Hunan Province, oranges can be extended for 4 to 5 months by using garlic leaves or garlic heads for mashing or slicing water to soak oranges. The average good fruit rate is about 95%. The specific method is: The garlic leaves or garlic heads are chopped and sliced, placed in clean water, the ratio of garlic to water is 1:10, soaked for 12 hours until the boiling point. After cooling to room temperature, it will be strictly selected and not broken. The fresh citrus without pests and diseases is soaked in garlic water for 10 to 15 seconds. After the water is taken out, it can be stored by conventional methods. The principle of this method of storing citrus is: garlic contains sterilizable natural chemicals that can be used as citrus preservatives. The citrus peel treated with this method is smooth and shiny, and the micro-spices of garlic have a spicy taste. The pulp has no other odor and is harmless to the human body after eating.
