Problems solved by technology

However, in the process of repeated stacking and drying, the water in the persimmon pulp gradually evaporates, and the glucose and fructose contained in the pulp penetrate into the surface layer. The processing time is long, and the surface of persimmons is easy to stick to dust, which affects the frosting. After the persimmon frost appears, the dust and persimmon frost are mixed, which is not easy to remove, resulting in mildew and corruption of persimmons, which seriously shortens the shelf life of persimmons.
In addition, the ripening degree and quality control of persimmons in the stacking and drying process are all based on experience, and it is difficult to quantify the operation and realize industrialized mass production.

Embodiment 1

[0028] This embodiment includes the following steps:

[0029] S1, fruit selection: select persimmons with complete fruit bodies, no pests and diseases, and ripe yellowish reddish skin, and ventilate and dry at room temperature for 12 hours;

[0030] S2. Peeling: Peel the dried persimmons in step S1, then soak them in a 2% konjac glucomannan solution for 3 minutes, and then take them out to dry;

[0031] S3, deastringency: Knead the dried persimmons in step S2 until the surface of the persimmons is complete, the inner pulp is soft and free of hard lumps and joint tissues, and then deastringent treatment is performed; the specific process of deastringency treatment is as follows: : the kneaded persimmons were treated at a temperature of 85° C. for 4 minutes and cooled to room temperature, and then treated at a temperature of 70° C. for 8 minutes and cooled to room temperature;

Abstract

The invention discloses a persimmon processing method. The persimmons are air-dried, peeled, kneaded and decolorized, and then ripened for the first time, softened for the first time, ripened for the second time, softened for the second time, and finally stored for frosting to obtain the dried persimmons. In this method, konjac glucomannan solutions with different mass contents are used to dip-coat persimmon pulp in the peeling, ripening and frosting stages of persimmon processing, and the film-forming and antibacterial properties of konjac glucomannan solution are used to combine two steps at the same time. The high-temperature short-time treatment method and medium-temperature baking accelerate the deastringency and ripening of persimmon pulp, promote the formation of persimmon frost, improve the quality and flavor of persimmon, prolong the shelf life of persimmon, and realize the clean production of persimmon; The process of the method is reasonable, each process index is complete and feasible, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of agricultural product processing methods, and in particular relates to a persimmon processing method. Background technique [0002] Persimmon is a traditional dried fruit in my country, which is processed from persimmons in the sun. Dried persimmons are delicious and nutritious. The content of sugars such as fructose and glucose is as high as 65%, and it contains a variety of vitamins, which have the effect of nourishing and fitness. According to the "Compendium of Materia Medica", persimmons clear the nose, cure gastrointestinal insufficiency, relieve alcohol poisoning, suppress stomach heat, and relieve dry mouth; and the persimmon frost covered on the persimmons has the effects of promoting body fluids and quenching thirst, clearing heat and moistening lungs, stopping bleeding and relieving coughs. [0003] The traditional persimmon processing method first cleans the persimmons, scrapes the skin, ventilates and ...
