Abstract

The invention discloses a sterilization method of an edible fungus stick. The sterilization procedure contains 6 periods: temperature increasing I, temperature preservation I, temperature increasing II, intermittent temperature increasing I, temperature preservation II and intermittent temperature increasing II. The microwave power in temperature increasing I is 1.5-2.0 kW, and the sterilization time is 12-40 min; the microwave power in temperature increasing II is 1.0-1.5 kW, and the sterilization time is 0-60 min; the microwave power in intermittent temperature increasing I is 0.5-1.0 kW, the time in intermittent temperature increasing I comprises microwave work time and intermittent time, each time is 0-60 seconds, and total time is 0-200 min; the microwave power in intermittent temperature increasing II is 0.2-0.5 kW, the time in intermittent temperature increasing I comprises microwave work time and intermittent time, each microwave time is 0-20 seconds, intermittent time is 0-40 seconds, and total time is 0-500 min; the time in temperature preservation I is 0-60 min; the time in temperature preservation II is 0-60 min. The problems of traditional steam sterilization of being long in sterilization time, low in efficiency, high in cost and prone to environmental pollution are solved, and edible fungus stick steam sterilization is a safe, efficient, energy-saving and environment-friendly sterilization method.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and in particular relates to a method for sterilizing edible mushroom sticks. Background technique [0002] After the reform and opening up, edible fungus has developed into an emerging industry and a sunrise industry, known as contemporary high-efficiency agriculture, ecological agriculture, characteristic agriculture and foreign exchange-earning agriculture. The "2015-2022 China Edible Mushroom Industry Research and Investment Consulting Report" released by China Industry Information Network pointed out that: my country's edible fungus industry is in a stage of rapid growth, and the total output has increased from 6.64 million tons in 2000 to 35.32 million tons in 2014. , the average annual compound growth rate was 12.7%, and the total output value increased from 22.7 billion yuan in 2000 to 235.6 billion yuan in 2014, with an average annual compound growth rate of 18.2%. At p...
