Composite biological film-coating antistaling agent

The invention provides a novel edible biological film-coating antistaling agent with good preserving effect as well as good water solubility and oxygen insulation simultaneously by adopting a novel biological safe food additive which has no toxic and side effect on a human body. The biological film-coating antistaling agent can form a layer of extremely thin film on the surface of fruit, vegetables and edible fungi, can effectively prevent gas exchange between the fruit, the vegetables and the edible fungi and the ambient environment, reduce water evaporation in food, prevent oxidation between oxygen in the air and the food, and better maintain the nutritive value of the fruit, the vegetables and the edible fungi. The coated film has good transparency so as to be capable of increasing the luster of the fruit, the vegetables and the edible fungi, and has good solubility so as to be easy to clean. Simultaneously, the coated film contains a biological antiseptic which can well inhibit and kill bacteria and fungi on the surface of the fruit, the vegetable and the edible fungi and in the ambient environment, so that the preservation period of fresh fruit and vegetables and the edible fungi can be effectively prolonged. Moreover, the novel film-coating antistaling agent adopts the biological additive, can be safely eaten, and has no toxic and side effect on the human body.
