Key points of operation
① Selection of raw materials: high-quality yellow peaches with maturity of 8.5%, freshness, fullness, no diseases, insect pests and mechanical injuries, and diameter of more than 5cm are selected.
(2) Cutting into pieces and digging the core. Cut the yellow peach in half longitudinally along the joint, and do not skew to cause large or small blocks. After cutting in half, soak the yellow peach slices in 2% salt water to protect the color. Dig the peach core from the cut semi-yellow peach block with a core digger, and dig it smooth and oval, but the fruit should not be dug too much or broken, and the red pulp can be left slightly. After digging the core, it should be soaked in alkali in time or soaked in 2% salt water to protect the color.
(3) Peeling and rinsing: evenly spread the peach pit downwards on the steel wire mesh of the alkali ironing machine in a single layer, so that the peel is fully washed by alkali liquor. The alkali liquor concentration is 6% ~12% and the temperature is 85 ~ 90℃. The treatment time is 30-70s, and then the lye is washed with clear water.
(4) pre-boiling: put the washed alkali liquor Zhi Tao block into a hot solution containing 0. 1% citric acid, and blanch it at 90 ~100℃ for 2 ~ 5 minutes until the peach block is translucent. Immediately after blanching, cool with cold water.
⑤ Trimming and canning. Use a sharp knife to cut off spots and residual dander on the surface of peach blocks. The trimmed peach pieces are canned separately according to different colors and sizes, and the canned amount should be no less than 55% of the net weight. Immediately after canning, hot sugar water with the concentration of 25% ~ 30% above 80℃ was injected, and 0. 1% citric acid and 0.03% isoVC were added.
⑥ Exhaust and sealing: Thermal exhaust shall be carried out in the exhaust box, and the tank shall be sealed immediately when the central temperature reaches 75℃. Or vacuumizing and exhausting, and the vacuum degree is 0.03-0.04 MPa.
⑦ Sterilization and cooling Sterilization in boiling water10 ~ 20min, and then cooling to about 38℃.
Ingredients: fresh yellow peach 3-4 crystal sugar 30g.
