(l) The main raw material (to produce 100 kg of finished product) Apple 160-180 kg, sugar 70 kg.
(2) The choice of materials and pre-processing, apple crucible production generally "Guangguang", "Ruan Jin", "Red Five" and so on as well. When making, choose the fruit that is intact and free of pests and diseases. After being turbid or chemically peeled, remove it and rinse it with clean water after nucleation.
(3) Smoke-smoke treatment, the apple after the previous treatment need to be sulphur treatment, sulphur smoking method is to burn sulphur in the air to produce sulphur dioxide, soluble in fruit juice, because sulphur dioxide has a strong reduction, on the one hand captured Oxygen required for the oxidation of tannins: On the other hand, it also inhibits the activity of various enzymes in fruits to a certain extent, thus effectively preventing the browning of fruits. The amount of smoked sulphur is about 0.2-0.3% of the fruit material, and the time is 30-60 minutes.
In addition, it can also be soaked with sodium bisulfite instead of smoked sulfur. Use sodium bisulfite solution concentration is generally 0.3-0.6%, soaking time 30-120 minutes.
(4) cooking and dipping, take the water 30 pounds, sugar 45 pounds, citric acid l two boiled sugar in the pot, and then put l10 pounds of the apple after treatment, heating before boiling for about 10 minutes, remove a few When the fruit was softened, 50% of the 50% sugar liquid was poured, and after the sugar liquid was boiled, two sugar liquids were added according to the above method. After boiling, add 3 to 5 pounds of dry sugar and 1 to 2 pounds of concentrated sugar for 10 minutes. Finally add 2-3 times of granulated sugar according to the cooking conditions, 10-20 pounds each time. After the last addition of sugar, it is boiled for about 20 minutes. When the sugar concentration reaches 65% or more, it is poured into the cylinder and soaked. Note that the entire cooking time is about 1.5-2 hours and the dipping time is l-2 days.
