Embodiment 1

[0016] A preparation method of dried longan, comprising the following steps:

[0017] 1. Select large, thick and fully mature longan fruits with a stalk length of 1-2mm, and screen and remove diseased and pest fruits and injured fruits;

[0018] 2. Put the selected longan fruit into hot water at 85-100°C for 2-3 minutes and then remove;

[0019] 3. Put the fished longan fruit into the dryer for drying. The temperature in the dryer is set at 60°C for 10 minutes;

[0020] 4. First heat the medical stone granules to 80°C, then add the dried longan fruit and bake for 30 minutes, turning the longan fruit every 5 minutes;

[0021] 5. After the baked longan fruit is naturally cooled, it is vacuum packed.

Embodiment 2

[0023] A preparation method of dried longan, comprising the following steps:

[0024] 1. Select large, thick and fully mature longan fruits with a stalk length of 1-2mm, and screen and remove diseased and pest fruits and injured fruits;

[0025] 2. Put the selected longan fruit into hot water at 85-100°C for 2-3 minutes and then remove;

[0026] 3. Put the fished longan fruit into the dryer for drying. The temperature in the dryer is set at 65°C for 8 minutes;

[0027] 4. First heat the medical stone granules to 90°C, then add the dried longan fruit and bake for 25 minutes, turning the longan fruit every 6 minutes;

[0028] 5. After the baked longan fruit is naturally cooled, it is vacuum packed.

Embodiment 3

[0030] A preparation method of dried longan, comprising the following steps:

[0031] 1. Select large, thick and fully mature longan fruits with a stalk length of 1-2mm, and screen and remove diseased and pest fruits and injured fruits;

[0032] 2. Put the selected longan fruit into hot water at 85-100°C for 2-3 minutes and then remove;

[0033] 3. Put the fished longan fruit into the dryer for drying. The temperature in the dryer is set at 70°C for 5 minutes;

[0034] 4. First heat the temperature of the medical stone granules to 95°C, then add the dried longan fruit and bake for 20 minutes, turning the longan fruit every 5 minutes;

[0035] 5. After the baked longan fruit is naturally cooled, it is vacuum packed.

Abstract

The invention discloses a preparing method of a dried longan, and belongs to the technical field of fruit processing. The preparing method comprises the steps of selecting fully ripe longan fruit with big size and thick fresh, leaving length of the peduncles to be 1-2 mm, and sifting and removing pest infringed fruit and wound fruit; putting the selected longan fruit into hot water at the temperature of 85 DEG C-100 DEG C, and fishing out the longan fruit after blanching the longan fruit for 2-3 minutes; putting the longan fruit obtained from the last step into a dryer, setting the drying temperature to be 60-70 DEG C and the drying time to be 5-10 minutes, and carrying out drying on the longan fruit; heating the medical stone particle to the temperature of 80 DEG C-95 DEG C, adding the dried longan fruit and carrying out roasting for 20-30 minutes, and stirring the longan fruit every 5-6 minutes; conducting vacuum packaging of the longan fruit after carrying out natural cooling on the roasted longan fruit. The preparing method of the dried longan has the advantages of being simple in procedures, short in cycle, high in yield rate, and long in storage time. Besides, the adoption of medical stone to carry on roasting can enrich nutritional ingredients of the longan fruit.

Description

technical field [0001] The invention relates to the technical field of fruit processing, in particular to a preparation method of dried longan. Background technique [0002] Dried longan, also known as dried longan, is a nutritious tonic that is popular among consumers, and has a large consumer market all over my country.
