Abstract

The invention provides a food adsorption and antibacterial pad. The food adsorption and antibacterial pad is composed of a low-density polyethylene plastic film and an inner adsorption antibacterial layer, wherein fine holes are punched in the upper surface of the low-density polyethylene plastic film; the inner adsorption antibacterial layer is composed of an antibacterial coating and an adsorption layer; the antibacterial coating is fitted on the upper surface of a first non-woven fabric in a coating manner; the adsorption layer is uniformly sealed between the lower surface of the first non-woven fabric and the upper surface of a second non-woven fabric. The food adsorption and antibacterial pad has the advantages that the design is ingenious; the food adsorption and antibacterial pad has three functions of absorbing water, adsorbing objectionable odor and resisting bacteria, and can be used for absorbing liquid oozed by chilled fresh meat which is stored for a long time; the relative humidity in packages is reduced and the bacteria and the peculiar smell are reduced; the guarantee period of the chilled fresh meat on a tray is prolonged; the preparation method has a simple process and is convenient to operate.

Description

technical field [0001] The invention relates to a food adsorption antibacterial mat and a preparation method thereof, in particular to an adsorption antibacterial mat suitable for keeping fresh meat on trays and a preparation method thereof. Background technique [0002] The proportion of fresh meat on pallets in domestic supermarkets is increasing year by year. During the storage and sales process of chilled meat on pallets, a large amount of juice will be leached with the increase of storage time, which will reduce the sensory quality of chilled meat and make it The increase of the relative humidity in the packaging causes a large amount of liquid to accumulate on the surface of the chilled meat and the so-called "sweating" phenomenon occurs. At the same time, it is easy to promote the growth of microorganisms, shorten the shelf life of the chilled meat, and seriously affect the commercial value of the chilled meat.
