Embodiment 1
[0025] Take 3g of nano-silicon-based oxide, add it into 70°C water, stir evenly and keep it warm, then add 1g of sodium dodecylsulfonate, keep it in a water bath for 20 minutes to modify it, add water to measure it to 1kg, and obtain a solution ①; take 100g of pectin, heat to dissolve In water, add 20g of D-sodium iso-Vc after cooling, add water to 9kg, and then mix with the above solution ① to obtain 10kg of composite preservative for peeled sugarcane.
[0026] Choose sugarcane that is basically the same size and free from damage, diseases and insect pests, peel it, cut it into small pieces of about 15 cm, soak it in the above compound preservative solution for 3 to 5 minutes, remove it and dry it, then put the sugarcane into a plastic box, put it in a Store at a temperature of 10-15°C.
Embodiment 2
[0028] Take 6g of nano-silicon-based oxide, add it into 75°C water, stir evenly and keep it warm, then add 2g of sodium dodecylsulfonate, keep it in a water bath for 30 minutes to modify it, add water to measure it to 1kg, and obtain a solution ①; take 150g of pectin, heat to dissolve In water, add 40g of D-sodium iso-Vc after cooling, add water quantitatively to 9kg, and then mix with the above solution 1. to obtain 10kg of composite preservative for peeled sugarcane.
[0029] Choose sugarcane that is basically the same size and free from damage, diseases and insect pests, peel it, cut it into small pieces of about 15 cm, soak it in the above compound preservative solution for 3 to 5 minutes, remove it and dry it, then put the sugarcane into a plastic box, put it in a Store at a temperature of 10-15°C.
Embodiment 3
[0031] Take 9g of nano-silicon-based oxide, add it into 80°C water, stir evenly and keep it warm, then add 3g of sodium dodecylsulfonate, keep it in a water bath for 40 minutes to modify it, add water to measure it to 1kg, and obtain a solution ①; take 200g of pectin, heat to dissolve In water, add 60g of D-sodium iso-Vc after cooling, add water to quantitatively reach 9kg, then mix evenly with the above-mentioned solution ① to obtain 10kg of composite preservative for peeled sugarcane.
[0032] Choose sugarcane that is basically the same size and free from damage, diseases and insect pests, peel it, cut it into small pieces of about 15 cm, soak it in the above compound preservative solution for 3 to 5 minutes, remove it and dry it, then put the sugarcane into a plastic box, put it in a Store at a temperature of 10-15°C.
