Problems solved by technology

[0003] At present, post-harvest mushroom storage and preservation usually use low-temperature methods combined with chemical preservatives, but it is well known that chemical preservatives face problems such as residual pollution, drug resistance, and environmental pollution. Therefore, there is an urgent need for a new type of safe and efficient preservative. Post-harvest storage of mushrooms

Embodiment 1

[0018] Step 1. The Agaricus bisporus is transported back to the laboratory on the same day after harvesting, and the samples with no mechanical damage, the same size, and good color are selected and randomly packed in fresh-keeping boxes, and placed in the air with a relative humidity of 90%-100% and a constant temperature of 4°C Pre-cooling in the storage room for 24 hours;

[0019] Step 2, use fresh Agaricus bisporus with CO 2 Airtightly package the gas in a modified atmosphere packaging box, and then transfer it to a storage room at 4°C for 12 hours, CO 2 The gas concentration is 95%-100%;

[0020] Step 3, punching holes in the modified atmosphere packaging box, releasing the gas in the box and continuing to store it.

Abstract

The invention discloses a modified atmosphere fresh-keeping method of agaricus bisporus. The modified atmosphere fresh-keeping method comprises the following steps: step 1, hermetically packaging the fresh agaricus bisporus by using a modified atmosphere packaging box containing 95-100 percent of CO2 and then transferring into a storage room with a temperature of 4 DEG C to store for 12-24 hours; step 2, punching in the modified atmosphere packaging box, discharging gas in the box and continuously storing. The modified atmosphere fresh-keeping method of the agaricus bisporus, disclosed by the invention, is simple to operate and convenient to use; the agaricus bisporus treated by the method can restrain agaricus bisporus browning and quality decline in the low-temperature storage process, so that the shelf life of the agaricus bisporus is safely and effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of postharvest storage and quality control of Agaricus bisporus. More specifically, the present invention relates to a modified atmosphere preservation method of Agaricus bisporus. Background technique [0002] Agaricus bisporus is one of the mushroom varieties that are widely planted and consumed in the world. The meat is thick and delicious. However, fresh mushrooms have high water content and no skin protection on the surface, so they are vulnerable to mechanical damage. Browning and umbrella opening occur during storage. Post-ripening phenomenon, high post-harvest loss, usually stored at room temperature for about 3-4 days, loses commodity value. The main reason is that the browning phenomenon during post-harvest storage of Agaricus bisporus seriously affects the appearance, and its surface lacks protective tissue. The skin shrinks due to transpiration and water loss during storage. In addition, local ...
