Abstract

The invention provides a bagasse-based nano antibacterial fresh-keeping film and a preparation method thereof, and relates to the field of crop straw utilization. The bagasse-based nano antibacterialfresh-keeping film comprises the following components in percentages by weight: 60%-80% of bagasse nanocellulose, 10%-30% of chitin nano crystal whiskers, 1%-5% of cinnamon essential oil, 3%-10% of chitosan, 1%-3% of glycerin, and 1%-3% of sorbitan fatty acid ester. The invention also discloses the preparation method of the bagasse-based nano antibacterial fresh-keeping film. According to the method provided by the invention, the nano antibacterial fresh-keeping film prepared by the method has better strength and gas permeability, the surface of the film can be uniformly moistened and forms awater film, so that external microorganisms are prevented from entering the film; and the added cinnamon essential oil and chitosan can inhibit growth and reproduction of microorganisms, so that shelflife of fruits is prolonged.

Description

technical field [0001] The invention relates to the field of biomass reuse, in particular to a bagasse-based nano antibacterial fresh-keeping film and a preparation method thereof. Background technique [0002] Fruit production is highly seasonal and regional. In order to meet consumers' demand for fruit, it is necessary to improve the fresh-keeping technology of fruit and prolong the market cycle of fresh fruit. However, fresh fruits still have high physiological activity after harvesting, especially fruits with high water content are more likely to rot and deteriorate. Therefore, prolonging the storage and transportation preservation time becomes the key to maintaining and increasing the value of fresh fruits. [0003] At present, the commonly used fruit preservation techniques mainly include low-temperature storage, controlled atmosphere preservation, and adding chemical preservatives. However, these techniques have certain limitations in practical applications. Cold ch...
