Embodiment 1

[0017] A method for making dried apples, comprising the following steps:

[0018] (1) Slicing: Wash the selected apples and slice them;

[0019] (2) Color protection: Soak the cut apple slices in salt water for 5 minutes, remove them, wash them repeatedly and dry them;

[0020] (3) Sterilization: Sterilize the dried apple slices at high temperature at 80°C for 20 minutes. After the sterilization is completed, place them in a cooler to cool them down;

[0021] (4) Drying: After cooling, put the dried apples in a drying machine to dry for 5 minutes, and then put them in an oven for dehydration and drying. The temperature of the oven is 50°C, and the drying time is 4 hours;

[0022] (5) Re-sterilization: re-sterilize the dried apple slices at high temperature at 100°C for 40 minutes;

[0023] (6) Vacuum packaging: The apple slices that have been sterilized again can be vacuum-packed after being dehydrated and dried in an oven. The oven temperature is 50°C and the drying time is...

Embodiment 2

[0025] A method for making dried apples, comprising the following steps:

[0026] (1) Slicing: Wash the selected apples and slice them;

[0027] (2) Color protection: Soak the cut apple slices in salt water for 15 minutes, remove them, wash them repeatedly and dry them;

[0028] (3) Sterilization: Sterilize the dried apple slices at high temperature at 120°C for 10 minutes. After the sterilization is completed, place them in a cooler to cool them down;

[0029] (4) Drying: After cooling, put the dried apples in a drying machine to dry for 10 minutes, and then put them in an oven for dehydration and drying. The temperature of the oven is 80°C, and the drying time is 2 hours;

[0030] (5) Re-sterilization: re-sterilize the dried apple slices at 120°C for 20 minutes;

[0031] (6) Vacuum packaging: The apple slices that have been sterilized again can be vacuum-packed after being dehydrated and dried in an oven. The oven temperature is 60°C and the drying time is 1.5h.

Embodiment 3

[0033] A method for making dried apples, comprising the following steps:

[0034] (1) Slicing: Wash the selected apples and slice them;

Abstract

The invention discloses a preparation method of dried apple. The method comprises a series of steps such as slicing, color-protecting, sterilizing, centrifugal drying, re-sterilizing, and packaging. No sugar is added during the preparation step, and no sulfuring step is adopted, such that nutrient loss is low, and the prepared dried apple has sweet and crispy taste and an intrinsic fragrance of apple. The preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to a food processing method, in particular to a method for processing fresh apples into dried apples. Background technique [0002] The traditional processing method of apple slices usually adopts the production process of material selection, peeling, cutting, heart removal, calcium sulfur treatment, sugar boiling, sugar staining, drying, shaping, and packaging. Because the apple slices produced by this method The sugar content is relatively high, which has certain side effects on human health. [0003] The patent application number is 201010268197.9 "A Processing Technology for Apple Slices", which provides a production method without sugar dipping, but it adopts the method of sulfur fumigation. Although the side effects of eating after sulfur fumigation cannot be determined, it is a non-candied fruit after all. Natural methods can be harmful to the body. And the apple slices that these preparation methods make all have soft el...
