Abstract: On the premise of ensuring traditional properties and characteristics of air-dried beef,the technology was improved to control the temperature and humidity of hurricane drier.The drying process on the prairie was simulated.The air-dried beef were fried twice at low and high temperatures.The vacuum-packed and two-stage sterilized technologies were used,which greatly shortened the production cycle and increased the production efficiency.Meanwhile,the amounts of harmful and putrefactive microorganism in products were decreased and the shelf-life of air-dried beef was prolonged,thus the economic benefit was remarkably increased.
