Embodiment 1

[0024] A kind of beef jerky environmental preservation bag in the present embodiment comprises following components by weight:

[0025]

[0026]

[0027] The specific steps of the preparation method are as follows: according to the above formula by weight, 50 parts of polylactic acid resin with a specification of 4032D and a weight average molecular weight of 230,000 are melted, and then 20 parts of nano-titanium dioxide, 12 parts of propolis, 10 parts of tea polyphenols and chitosan are added. The preservative, 4 parts of stearic acid dispersant and 3 parts of glycerin plasticizer mixed at a mass ratio of 1:1 are mixed evenly, and then melt blended and extruded at a temperature of 180°C using a twin-screw extruder. Granules to obtain masterbatches, and then put the masterbatches into an extrusion blown film machine at a temperature of 190°C to extrude and blow the film into a fresh-keeping bag, and cool to room temperature in a natural state.

Embodiment 2

[0029] The preparation method of this embodiment is the same as that of Example 1, except that the beef jerky environmental preservation bag in this embodiment contains the following components by weight:

[0030]

Embodiment 3

[0032] The preparation method of this embodiment is the same as that of Example 1, except that the beef jerky environmental preservation bag in this embodiment contains the following components by weight:

[0033]

[0034] Carry out the test of mechanical strength and antibacterial performance to the fresh-keeping bag that embodiment prepares, test is as follows: bag thickness 0.2mm, tensile strength 90.2Mpa, bursting degree is 10324.6Mpa / m 2 , The antibacterial rate of the prepared fresh-keeping bag is 95.3%, the rate of inhibition of mold is 97.6%, and the rate of inhibition of yeast is 98.6%.

Description

technical field [0001] The invention belongs to the technical field of food fresh-keeping, and in particular relates to an environmental-friendly fresh-keeping bag of beef jerky and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of living standards, people have higher and higher requirements for food quality. Among them, food preservation has been paid more and more attention by people. Because physical fresh-keeping (including refrigeration, air-conditioning, etc.) cannot control low-temperature microorganisms, and requires large-scale equipment; chemical preservatives have certain safety hazards; and natural preservatives are safe, non-toxic, and easy to operate. Therefore, The importance of natural preservatives is increasing. Edible and fully degradable nano-composite environmental protection materials are food packaging materials made by compounding natural polymers and nano-additives. Food packaging materi...
