Bitter gourd biological fresh-keeping agent as well as preparation method and use method thereof

Abstract

The invention relates to a bitter gourd biological fresh-keeping agent, and a preparation method and a use method thereof. The biological fresh-keeping agent is prepared by the following steps: addingwater into green herbal medicines including populus euphratica leaves, aloe, polygonum cuspidatum and garlic bulbs, and cooking and cooling; and filtering to obtain clear liquid, namely the biological fresh-keeping agent. The bitter gourd biological fresh-keeping agent disclosed by the invention can form a protective layer on the surfaces of fruits, loss of moisture and nutritional ingredients iseffectively prevented through plastic preservative film packaging; meanwhile, the antibacterial components in the biological fresh-keeping agent can effectively prevent invasion of germs and reduce the rotting rate of fruits, biological preservation substances are odorless, non-toxic and harmless, the bitter gourds are still fresh as before after being stored for two months at the normal temperature, the preservation time of the shelf can be prolonged by two months or above, and the preservative is convenient to use and has excellent market popularization prospects.

Problems solved by technology

Storage under controlled atmosphere is sensitive to oxygen concentration, carbon dioxide concentration, and ethylene. Even if the control is intact, it can only be stored for 2 to 3 weeks under suitable conditions. However, mechanical low-temperature controlled atmosphere storage is expensive, energy-consuming, and unstable in quality. Rarely used, difficult to promote

Due to the widespread contact or proximity of pharmaceuticals and bitter melon, it is easy to cause pollution and bring health hazards and other problems. Biological fresh-keeping technology overcomes the disadvantages and drawbacks of the above-mentioned fresh-keeping methods, and the processing cost is low, which meets the requirements of green environmental protection and can save Resources, and reduce energy waste, prevent pollution and other advantages. In recent years, with the improvement of living standards, consumers have higher and higher requirements for food safety. Everyone hopes to eat natural, safe, and chemical-free food. Therefore, , to develop new, safe and efficient fresh-keeping products, it is more urgent and important to use biological fresh-keeping bitter gourd to prevent bitter gourd from rotting and deteriorating
