The invention relates to a ready-to-eat 
edible mushroom (
pleurotus eryngii) leisure food and a preparation method thereof, in particular to a 
novel treatment method for improving the 
processing course of 
edible mushroom (
pleurotus eryngii). The preparation method comprises the following steps of selection of raw materials, cleaning, trimming, tearing by hands, rinsing, 
scalding, fixation, vacuum rolling, 
ageing disinfection and 
vacuum packing. According to the preparation method disclosed by the invention, the 
pleurotus eryngii is 
cut into dices of which the 
fiber direction after being torn by hands is consistent with the 
fiber direction of the 
pleurotus eryngii, so that the integrity of fibers is maintained, and the growth of 
beneficial bacteria such as bifidobacteria is maintained; the 
nutrient components of the 
pleurotus eryngii are maintained not to be lost, so that the 
nutrient value of products is high. The steps of rinsing, 
scalding and fixation are performed with normal 
saline of 0.9% at 95 DEG C, so that the physiological status of the 
pleurotus eryngii is maintained, and the 
nutrient substance of the pleurotus eryngii is prevented from being destroyed. Few nutrient components run off, and the nutrient value of the product is higher than that of a conventional product. The ready-to-eat 
edible mushroom (pleurotus eryngii) leisure food disclosed by the invention is delicious in taste, and rich in perfume, can be used as a mixed ingredient of the food and can also be used as a leisure food, so that the ready-to-eat edible 
mushroom (pleurotus eryngii) leisure food is broad in market prospects.
