[0002] Vacuum packaging of biscuits is a packaging technology, the main purpose of which is to extend the shelf life of biscuits and maintain their freshness and taste. By placing biscuits in vacuum packaging bags and removing the air in the vacuum packaging bags to form a vacuum state, the chance of biscuits coming into contact with oxygen can be effectively reduced, thereby slowing down the oxidation process and preventing the biscuits from deteriorating. In addition, vacuum packaging can also prevent biscuits from absorbing external moisture and preventing them from becoming damp and soft, thus ensuring the quality of biscuits during transportation and storage. Rice biscuits are a healthy snack made from rice as the main raw material. In the process of making rice biscuits, rice is usually ground into powder first, then mixed evenly with other auxiliary materials, and then processed by molding, baking and other processes.
