AI Technical Summary

Problems solved by technology

Most of the existing drying methods are natural exposure, hot air drying, microwave drying, etc. The formaldehyde content of the shiitake mushrooms produced by them is high, which reduces the edible value, and the rehydration of the dried shiitake mushrooms is not good, and the time of soaking in cold water is longer. At least 40 minutes or more, although the time of soaking in hot water can be shortened, but it will affect the taste, and this method is usually not used

Embodiment 1

[0027] A drying method for improving the quality of shiitake mushrooms, comprising the steps of:

[0028] (1) Cleaning pretreatment:

[0029] Wash the shiitake mushrooms with clean water, and then remove the longer stipe for later use;

[0030] (2) Primary drying treatment:

[0031] Put the shiitake mushrooms processed in step (1) into a drying box for a drying treatment, dry until the water content of the shiitake mushrooms is 15-16%, and take them out for later use;

[0032] (3) Soaking treatment:

[0033] Put the shiitake mushrooms treated in step (2) into the soaking solution, heat to keep the temperature of the soaking solution at 55-56°C, take out after soaking for 2 hours for later use; the soaking solution is a saline solution with a mass fraction of 0.7%;

[0034] (4) Freezing treatment:

[0035] Put the shiitake mushrooms processed in step (3) into the freezer, control the temperature in the freezer to -8°C, freeze for 1 hour and take them out for later use;

Abstract

The invention discloses a drying method of improving lentinus edodes quality. The method includes the following steps: (1) performing cleaning and pre-treatment; (2) performing first-time drying treatment; (3) performing soaking treatment; (4) performing freezing treatment; (5) performing microwave treatment; and (6) performing second-time drying treatment. The drying method provided by the invention can effectively remove the content of harmful substances like formaldehyde inside the lentinus edodes and the rehydration property of the lentinus edodes after being dried is remarkably improved. The rehydration time of the dried lentinus edodes is shortened to 3-5min. The dried lentinus edodes has an authentic color, a strong aroma and good appearance, has a relatively good taste when being eaten after rehydration and has strong market competitiveness and high economic benefits.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a drying method for improving the quality of shiitake mushrooms. Background technique [0002] Mushrooms belong to Basidiomycetes and are the second largest edible fungi in the world. Shiitake mushrooms are rich in nutrition, rich in various nutrients and bioactive substances such as active polysaccharides, proteins, dietary fiber, ergosterol, minerals, etc., and have various functional properties such as analgesic, anti-inflammation, anti-oxidation, anti-cancer, and blood pressure lowering , cholesterol-lowering effects. Lentinus edodes is a well-known edible fungus with the same origin of medicine and food. It is deeply loved by people and is known as the "Queen of Mushrooms". Fresh shiitake mushrooms are not resistant to storage, so shiitake mushrooms are often dried. [0003] As a common processing method in modern food processing, drying is widely used...
