The invention discloses a
processing method of preserved apples and relates to the field of
food processing and in particular relates to a
processing method of preserved apples. The
processing method comprises the following steps:
material selection and grading: selecting fresh and full apples without
plant diseases and
insect pests, and taking apples, the transverse diameters of which are greater than 75 mm, as a first grade, the transverse diameters of which are greater than 65mm but less than 74 mm, as a second grade, and the transverse diameters of which are less than 64mm, as a third grade; peeling,
petal cutting and sub-
nest removal: cleaning the apples and peeling the apples with a peeling
machine, wherein the peeling thickness does not exceed 1.2mm, performing rip
cutting on apples of the second and third levels to two petals, performing rip
cutting on apples of the first level to three petals, thoroughly digging the sub-nests and stems and peduncles of the apples with a core knife and removing the peels; and soaking and hardening: soaking the
cut apples into a solution of 0.1%
calcium chloride and 0.3%
sodium hydrogen sulfite for hardening and color-fixation, wherein the time is 10-15 hours, wherein the apples which are hard in meat are not hardened. The processing method disclosed by the invention is simple to operate and fast in
sugar infusion speed, and the prepared low-
sugar preserved apples not only are little in loss of nutrients, but also have a good effect in color and luster, plumpness, transparency, keeping property and the like.
