How to process Crystal Jujube
1. Selection of materials
Fresh jujube with no damage, no moth, no wrinkle, uniform size, moderate size, white maturity or brittle ripening period was selected as raw materials.
two。 Peeling
In the anti-alkali pot, add an appropriate amount of 7% Mui 8% alkali solution, heat and bring to a boil, pour the fresh dates into the pot, stir and boil for 3-5 minutes. When the skin turns brown, immediately fish into the 6% dilute sulfuric acid water solution tank and neutralize the acid and alkali for 10-15 minutes. When neutralizing to pH6-7, remove the jujube, wash it with water, and then remove the jujube skin by hand or peeling machine.
3. Soak the peeled jujube in sulfur and rinse the peeled jujube with water several times.
After washing, pour into a tank containing 0.2% sodium sulfite solution, soak for 40 minutes, remove and drain.
4. Sugar cooking
Add the right amount of water to the pot, bring it to a boil, add 52% Murray, 56% sugar and 0.6% citric acid; remove part of the sugar solution to cool and set aside. Then pour the jujube into the pot, immerse it with sugar solution, continue to boil for 60 minutes, and keep stirring to make the jujube heated evenly. After the sugar and acid solution is boiled, the cooling sugar and acid solution is gradually added to promote the jujube meat to permeate sugar and absorb acid. Cook until the jujube is transparent, and when you can clearly see the jujube kernel, stir and add the right amount of sugar to the pot and continue to cook for 15 minutes until the sugar concentration is 58%.
5. Soak
Pour the cooked sugar jujube and sugar solution into a clean tank immediately and soak for 24 hours to make it continue to absorb the sugar solution to a saturated state.
6. Baking
Put the soaked sugar jujube into the baking plate, put it in the baking room of 65-68 ℃, bake for about 24 hours, that is, the crystal jujube.
