, said that Conghua in Guangzhou is a famous “hometown of litchi”, and the most popular litchi varieties here are Guiwei and Nuomici. The fruit of Guiwei is more sharp, with prickles on it. The fruit is sweet and the core is small. However, the fruit of Nuomici is heart-shaped with strong sweetness and soft glutinous taste. Guiwei is a good variety of litchi.

First of all, because of the high sugar content of litchi, after picking, the respiration of the fruit is stronger than that of the general fruit. Within a few days after picking, it will become “old and pale”. Therefore, after picking litchi, “color changes in one day, aroma changes in two days, flavor changes in three days, and color and fragrance disappear in four days.”. At present, there is no good method to keep litchi fresh for a long time.

and

generally pick medium well of the fruit and put them in foam bags with ice bags and then transport them to markets across the country. However, the skin of immature litchi is greenish green, which affects the sales. Some vendors will soak or spray litchi with “fresh-keeping water” (made by adding a small amount of sulfuric acid or hydrochloric acid water) to soak or spray litchi, so that the litchi turns into a good-looking red color. Be vigilant when purchasing. The normal mature litchi of

and

are usually green and red with irregular color distribution. If the whole body is red, some of the convex points on the shell are black, it may be treated with “fresh water”. It should be noted that lychees sold in large supermarkets are usually mixed with ice or placed in refrigerated cabinets, which is conducive to fresh-keeping. Litchi without low-temperature preservation measures is better to buy less.
