How to keep button mushrooms fresh? These three methods are very practical
In order to extend the storage period of mushrooms, maintain their quality, color and flavor, and improve the cultivation benefits of mushrooms, the preservation techniques for mushrooms are introduced below. Mushroom growers can choose and apply them according to their own actual conditions. 1. Low-temperature preservation method. Practice has proved that low temperature can keep mushrooms fresh and of good quality. The method is: after mushrooms are harvested, their humidity is 90-95%; at this time, storing the mushrooms at 0-3°C can achieve the purpose of preservation. It is worth noting that during the preservation period, the temperature of the mushrooms should be kept

How to Identify Poisonous Mushrooms? 5 Practical Methods to Teach You
First, look at the color. Poisonous mushrooms have brightly colored caps, with colors such as red, green, ink black, and purple-blue; purple ones in particular are often highly toxic and tend to change color after being picked. Second, look at the shape. Non-poisonous mushrooms have relatively flat caps, smooth surfaces, no rings on the cap surface, and no volva at the base. Poisonous ones have oddly shaped caps, thick and hard cap surfaces, rings and volva on the stem, and thin or thick elongated stems that break easily. Third, look at the secretions. Non-poisonous mushrooms have thick, concentrated secretions that are reddish-brown and tend to change color in the air after being torn apart. Fourth, smell the odor. Non-poisonous mushrooms have a distinctive fragrance, while poisonous mushrooms have a strange

Physiological Disorders of Mushrooms and Their Control Methods
Mushrooms are relatively sensitive to their environment. A poor cultivation environment will hinder their normal growth and development, produce various abnormal phenomena, and lead to reduced yields and lower quality. Common physiological disorders of mushrooms include excessive mycelial growth, hard opening of the caps, thin-skinned early opening, and the appearance of ground-button mushrooms and hollow-stem white-core mushrooms. They are described below: Symptoms of excessive mycelial growth: after the casing soil of the mushroom bed is watered, the fluffy mycelium of the mushroom will continuously grow toward the surface of the fine soil, and in severe cases will form a fine, dense, water-impermeable mycelial mat, thereby delaying the time of fruiting and reducing the

How to Store and Keep Mushrooms Fresh? All the Practical Methods Are Here
Mushrooms are best eaten fresh, but since they do not keep long under natural conditions, especially when mushrooms are cultivated on a large scale, storage and preservation techniques can extend the selling period or allow them to be processed into canned products and other goods for export earnings. Here are several storage and preservation techniques for mushrooms: 1. Cold storage preservation. After the harvested fresh mushrooms are sorted, place them in containers such as baskets, trays or hampers and cover them with multiple layers of damp gauze or burlap. In a cool, shaded place, set out a vat filled with a small amount of clean water, place a wooden rack above the water, set the baskets or hampers holding the fresh mushrooms on the rack, and then seal the mouth of the vat with plastic film.

Detailed Explanation of Mushroom Topdressing Methods and Technical Key Points
During the peak fruiting stage and late growth stage of mushrooms, if the nutrients in the compost are insufficient, deformed mushrooms are easily produced, seriously affecting yield and quality. Timely topdressing can help mushrooms achieve high quality and high yield. When topdressing, alternating organic fertilizers and inorganic fertilizers gives better results. However, it is advisable to apply frequently in small amounts; generally, 2-3 topdressings can be applied per flush, carried out in conjunction with watering, with 250-500 milliliters per square meter. After fertilizing, spray clean water once to wash off the fertilizer solution on the mushroom bodies, and wait until the water droplets on the mushroom caps have dried before closing doors and windows. This method can avoid the occurrence of yellow spots,

Practical Methods and Technical Points for Anti-Aging of Mushrooms
1. Soaking in clean water: Water can block out air, slowing down the discoloration of mushrooms and keeping them plump. However, the water must have a low iron content; do not use iron containers or water with a high iron content for soaking. 2. Sodium metabisulfite treatment: First rinse the mushrooms with a 0.01% sodium metabisulfite aqueous solution for 3 to 5 minutes, then soak them in a 0.1% sodium metabisulfite aqueous solution for half an hour, remove and drain, and store in plastic bags. At a room temperature of 10°C to 15°C, the preservation effect is good, and the mushrooms can remain white for a long time. However, when the storage temperature exceeds 30°C, they can only be preserved for 1 day, after which they will gradually discolor.

Three Methods to Keep Mushrooms from Aging: A Detailed Explanation
Soaking in clean water. Water can block out air, slowing down the discoloration of mushrooms and keeping them plump, but you must use water with a low iron content for soaking. Treatment with sodium metabisulfite. First rinse the mushrooms in a 100 ppm sodium metabisulfite solution for 3-5 minutes, then soak them in a 1000 ppm sodium metabisulfite aqueous solution for 30 minutes, take them out and drain them, and store them in plastic bags. At a temperature of 10-15°C, the mushrooms can stay white for a long time.

Symptom Identification and Control Methods for Mushroom Brown Blotch Disease
Mushroom brown blotch disease, also known as dry bubble disease, is fairly widespread and occurs frequently on mushroom beds, causing great damage. Symptoms: When the disease occurs, brown spots usually form on the stipe, cap, and gills, and become sunken; the mushrooms often lose their firmness and become deformed. In severe cases, the mushrooms rot. Diseased young mushrooms are mostly deformed, with the edge of the cap appearing serrated, or the stipe bending; some look like garlic bulbs, with the stipe thicker than the cap. When large mushrooms are affected, localized brown spots usually appear; the diseased mushrooms later dry out and become leathery, and a gray mold layer forms on the diseased parts. Unlike white rot disease, the diseased mushrooms rot

Analysis of the Causes of Abundant Yellow Mushrooms and Prevention and Control Methods
The main causes are improper management during the low-temperature season. During the low-temperature season, the humidity inside the mushroom shed may be too high, with excessive watering, and too much free water adhering to the mushroom bodies. After absorbing water, it cannot evaporate, which weakens the metabolism of the mushroom bodies, causing various pathogens to take advantage of the opportunity, multiply in large numbers, and trigger various diseases of the fruiting bodies; continuous low-temperature weather causes the temperature inside the mushroom shed to be too low, and the edible fungus fruiting bodies remain in a poor living environment for a long time, leading to disease; some edible fungus varieties are at the 3rd to 4th flush during the fruiting period, and the nutrient supply in the fungus bags is insufficient. After budding, the

Introduction to Mushroom Processing Methods and Technical Points
I. Pickled Mushrooms in Soy Sauce 1. Salting the Base: Clean the mushrooms, remove debris, wash and drain them. At a ratio of 10-5 kg of salt per 100 kg, place the mushrooms in brine, just enough to submerge them. Seal and pickle for 1 week, turning them twice during this period so the salt penetrates evenly. 2. Soy Sauce Pickling: Remove the mushrooms and drain off the brine, soak them in clean water for one day, take them out and air-dry, then put them into a soy sauce jar and pickle them in soy sauce at a ratio of 50-70 kg of sweet bean sauce per 100 kg, with the temperature preferably at 20°C. During the soy sauce pickling period, stir once every morning, and after 10 days they can be taken out of the jar. They taste delicious and can be served either as a side dish
