Embodiment 1

[0028] (1) Add 0.1 part by mass of garlic powder (passable through a 50-mesh sieve) and 100 parts by mass of water to 5 parts by mass of starch, heat up to 75° C. under stirring, and continue to disperse for 30 minutes.

[0029] (2) Cool the product obtained in step (1) to 50°C, add a silver nitrate solution with a concentration of 0.5M (the added mass is equivalent to 0.1% of the starch mass), stir at a speed of 200rpm for 30 minutes, and mix well to obtain garlic-containing powder and nanosilver solution. The solution is a homogeneous light yellow translucent solution.

[0030] (3) Add water to the solution containing garlic powder and nano-silver to adjust the viscosity to 50cp at 50°C, coat it on the paper base of food packaging paper, the coating amount is 1GSM, and dry it conventionally to obtain antibacterial paper containing garlic powder .

Embodiment 2

[0032] (1) Add 5 parts by mass of garlic powder (which can pass through a 100-mesh sieve) and 100 parts by mass of water to 20 parts by mass of starch, heat up to 85° C. under stirring, and continue to disperse for 30 minutes.

[0033] (2) Cool the product obtained in step (1) to 50°C, add a silver nitrate solution with a concentration of 0.05M (the added mass is equivalent to 1% of the starch mass), stir at a speed of 100rpm for 60 minutes, and mix well to obtain garlic-containing powder and nanosilver solution. The solution is a homogeneous light yellow translucent solution.

[0034] (3) Add water to the solution containing garlic powder and nano-silver to adjust the viscosity to 30cp at 50°C, coat it on the paper base of food packaging paper, the coating amount is 2GSM, and dry it conventionally to obtain antibacterial paper containing garlic powder .

Embodiment 3

[0036] (1) Add 2 parts by mass of garlic powder (passable through a 50-mesh sieve) and 100 parts by mass of water to 10 parts by mass of starch, heat up to 70° C. under stirring, and continue to disperse for 30 minutes.

[0037] (2) Cool the product obtained in step (1) to 50°C, add a silver nitrate solution with a concentration of 0.3M (the added mass is equivalent to 0.5% of the starch mass), stir at a speed of 120rpm for 60 minutes, and mix well to obtain garlic-containing powder and nanosilver solution. The solution is a homogeneous light yellow translucent solution.

[0038] (3) Add water to the solution containing garlic powder and nano-silver to adjust the viscosity to 20cp at 50°C, coat it on the paper base of food packaging paper, the coating amount is 3GSM, and dry it conventionally to obtain antibacterial paper containing garlic powder .

Abstract

The invention discloses a bacteriostatic paper containing garlic powder, a preparation method and application thereof. In the present invention, starch, water and garlic powder are evenly mixed, and the temperature is raised to 70-85°C in a stirring state, and the dispersion is continued; then the temperature is lowered to below 50°C, and silver nitrate solution is added, stirred and mixed evenly, to obtain garlic powder and nano-silver solution; adjust the viscosity of the solution containing the garlic powder and nano-silver, coat it on the paper base, and dry to obtain the antibacterial paper containing the garlic powder. After the garlic powder and silver nitrate are combined in the present invention, the scope of the antibacterial spectrum is expanded, and the antibacterial ability is enhanced. Moreover, garlic powder can inhibit the oxidation of nano-silver prepared by silver nitrate, effectively prolonging the antibacterial time and effectiveness of nano-silver. The solution containing garlic powder and nano-silver provided by the invention is a uniform light yellow translucent solution; the solution is coated on a paper base and has good and long-lasting adhesion. Therefore, the antibacterial paper is suitable for application in the field of food packaging.

Description

technical field [0001] The invention belongs to the field of food wrapping paper, in particular to antibacterial paper containing garlic powder, a preparation method and application thereof. Background technique [0002] Food wrapping paper refers to the wrapping paper that is in direct contact with food. It not only requires the paper to have a certain strength, but more importantly, it is safe and hygienic. Chemicals with potential safety hazards cannot be added. Therefore, the antibacterial effect of food packaging paper is a problem. Even if the production process uses high-grade raw materials and high-temperature treatment, it still faces hygiene problems in the storage, transportation and distribution links. Natural and safe food preservatives can realize the function of food packaging paper to inhibit the growth of microorganisms. [0003] Modern medical research has confirmed that garlic has more than 100 kinds of medicinal and health-care ingredients, including 43 ...
