Key points of pre-processing of apple slices

Selection of raw materials: choose the fruits with dense flesh, high sugar content, thin skin and thick flesh, and fully mature fruits, and remove rotten and disabled fruits.

Raw material treatment: In order to remove the pesticides on the peel, the fruit is washed with running water. Peel and peel the fruit manually or mechanically, cut into 7-8 mm thick discs, and then put them in saltwater.

Color protection: Put the cut apple slices in a solution of 3% to 5% saltwater to protect the color to avoid oxidation and browning.

If the fruit pieces are floating on the potion, they should be pressed with a cover curtain weight on the fruit pieces to ensure that the fruit pieces are completely immersed in the potion.
