Embodiment 1

[0022] A kind of processing method of persimmon of the present embodiment, comprises the following steps:

[0023] (1) Sorting and cleaning: Pick persimmons with yellowed skin, fully matured flesh and hard and brittle flesh, remove rotten fruits and fruits with diseased insects, and rinse off the dust and impurities on the surface with clean water.

[0024] (2) Astringent removal treatment: soak the cleaned persimmons in an astringent-removing agent at 30°C for 10 minutes, put them in an airtight container, and remove the astringency at room temperature for 10 hours. During the astringent removal period, open the airtight container to ventilate once every 2 hours. Each aeration time is 5 minutes, and the preparation method of the deastringent agent is as follows: in parts by weight of raw materials, 10 parts of corn peptide, 8 parts of glutathione and 70 parts of 20% alcohol solution are mixed and stirred evenly, and the pH adjusted to 7, that is.

[0025] (3) Peeling: Peel t...

Embodiment 2

[0030] A kind of processing method of persimmon of the present embodiment, comprises the following steps:

[0031] (1) Sorting and cleaning: Pick persimmons with yellowed skin, fully matured flesh and hard and brittle flesh, remove rotten fruits and fruits with diseased insects, and rinse off the dust and impurities on the surface with clean water.

[0032] (2) Astringent removal treatment: soak the cleaned persimmons in an astringent-removing agent at 40°C for 20 minutes, put them in a closed container, and remove the astringency at room temperature for 15 hours. Each aeration time is 10 minutes, and the preparation method of the deastringent agent is as follows: in parts by weight of raw materials, 20 parts of corn peptide, 15 parts of glutathione and 100 parts of 30% alcohol solution are mixed and stirred evenly, and pH adjusted to 10, that is.

[0033] (3) Peeling: Peel the persimmons after deastringency treatment with a peeling machine, and the peeling should be clean, l...

Embodiment 3

[0038] A kind of processing method of persimmon of the present embodiment, comprises the following steps:

[0039] (1) Sorting and cleaning: Pick persimmons with yellowed skin, fully matured flesh and hard and brittle flesh, remove rotten fruits and fruits with diseased insects, and rinse off the dust and impurities on the surface with clean water.

[0040] (2) Astringent removal treatment: Soak the cleaned persimmons in a deastringent agent at 35°C for 15 minutes, put them in a closed container, and leave them at room temperature for 13 hours. During the deastringent period, open the airtight container to ventilate once every 2.5 hours , each aeration time is 8min, and the preparation method of the deastringent agent is as follows: in parts by weight of raw materials, 15 parts of corn peptide, 12 parts of glutathione and 90 parts of 25% alcohol solution are mixed and stirred evenly, and Adjust the pH to 8, that is.

Abstract

The invention discloses a processing method of dried persimmons, and relates to the technical field of processing of agriculture products. The processing method comprises six steps of performing sorting and cleaning; performing deastringent treatment: putting thoroughly-cleaned persimmons in a deastringent agent, performing soaking, loading the soaked persimmons in a closed container, performing deastringent treatment at room temperature for 10-15h, and during the deastringent treatment period, opening the closed container every 3-4h to perform ventilation once, wherein a preparation method ofthe deastringent agent comprises the steps of uniformly mixing and stirring 10-20 parts of corn peptide with 8-15 parts of glutathione and 70-100 parts of a 20-30% alcoholic solution and adjusting the pH to be 7-10; performing peeling; performing drying and shaping; performing frost appearance; and performing packaging. According to the processing method disclosed by the invention, a method of firstly performing low-temperature quick deastringent treatment and then performing high-temperature dehydration and baking is adopted, so that the deastringent problem of the dried persimmons is solved, and the made dried persimmons are transparent in meat quality, and sweet, delicious and pure in taste, and are superior foods suitable for both old and young people.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural product processing, in particular to a method for processing dried persimmons. 【Background technique】 [0002] Persimmons are beautiful in shape, large in size and thin in skin, thick in flesh and seedless, and sweet in taste. They are very popular among the public. However, persimmons contain high water and sugar content, high breathing intensity, easy to soften and deteriorate, and are not resistant to storage. Therefore, in addition to fresh food, People mostly process persimmons into persimmons. Persimmons are rich in nutrition, large and round in shape, transparent in flesh, sweet and pure in taste, and are good food for all ages. [0003] The production process of persimmons includes fruit picking, grading, cleaning, peeling, drying, molding, sulfur fumigation, frosting, packaging and other steps. Since persimmons have an astringent taste, generally the astringent taste is removed by...
