Embodiment 1
[0016] 1. A compound preservative for litchi is made up of a smear and a bacteriostatic agent, and each liter of the smear is composed as follows: 1 gram of sodium chloride, 10 grams of peanut oil, and the solvent is the acetic acid of volume concentration 10%; The composition of the bacteriostatic agent is as follows: 1 gram of Houttuynia cordata derivative, and the solvent is water.
[0017] 2. the described a kind of lychee compound preservative, described Houttuynia cordata derivative is prepared by the following method:
[0018] According to the number of parts by mass, 120 parts of Houttuynia cordata, 400 parts of epichlorohydrin, 1.0 parts of magnesium chloride and 1000 parts of 10% hydrochloric acid are added to the reactor, vacuumized, and then replaced with nitrogen in the reactor. Air, after repeating three times, fill with nitrogen, lower the temperature of the reaction system to 70°C under the protection of nitrogen, and react for 6h; after completing the reaction...

[0021] 1. A compound preservative for litchi is made up of a smear and a bacteriostatic agent, and each liter of the above-mentioned smear is composed as follows: 2 grams of sodium chloride, 15 grams of peanut oil, and the solvent is the acetic acid of volume concentration 10%; The antibacterial agent is composed as follows: 3 grams of Houttuynia cordata derivatives, and the solvent is water.
[0022] 2. the described a kind of lychee compound preservative, described Houttuynia cordata derivative is prepared by the following method:
[0023] According to the number of parts by mass, 125 parts of Houttuynia cordata, 410 parts of epichlorohydrin, 1.2 parts of magnesium chloride and 1000 parts of 10% hydrochloric acid are added to the reactor, vacuumized, and then replaced with nitrogen in the reactor. Air, after repeating three times, fill with nitrogen, lower the temperature of the reaction system under the protection of nitrogen to 80 ° C, react for 8 hours; after completing t...
Embodiment 3
[0026] 1. A compound preservative for litchi is made up of a smear and a bacteriostatic agent, and each liter of the above-mentioned smear is composed as follows: 3 grams of sodium chloride, 20 grams of peanut oil, and the solvent is the acetic acid of volume concentration 10%; The antibacterial agent is composed as follows: 5 grams of Houttuynia cordata derivatives, and the solvent is water.
[0027] 2. the described a kind of lychee compound preservative, described Houttuynia cordata derivative is prepared by the following method:
[0028] According to the number of parts by mass, 130 parts of Houttuynia cordata, 420 parts of epichlorohydrin, 1.5 parts of magnesium chloride and 1000 parts of 10% hydrochloric acid are added to the reactor, vacuumized, and then replaced with nitrogen in the reactor. Air, after repeating three times, fill with nitrogen, lower the temperature of the reaction system to 90°C under the protection of nitrogen, and react for 10h; after completing the...
