| titleOfInvention | A kind of preparation method of antibacterial PE film |
| abstract | The present invention provides a kind of preparation method of antibacterial PE film, including PE polyethylene antibiotic master batch, the anti-master batch of PE polyethylene includes polyethylene, antibacterial agent, crab mixture, antibacterial agent is natural antibacterial agent nisin, the crab mixture is ethylenediamine tetra-acetic acid, the production method of the antibacterial agent uses fermentation culture method to manufacture in the medium, and preparation step such as S1 mixed-culture medium, S2 froth, S3 saltouts, S4 washes light transmission, S5 goes out clear liquid, S6 prepares concentrate, S7 obtains nisin, S8 prepares master batch, S9 prepares finished product.The present invention passes through addition natural antibacterial agent nisin and ethylenediamine tetra-acetic acid crab mixture, effectively make that PE film has the effect of antibacterial and nisin is also a kind of nisin, effectively inhibit the bacterium and the spore that cause food spoilage, extending Shelf-life of Food-a Review reduces sterilising temp, shorten sterilization time, improve food quality, reduces energy consumption, substitution or part substituted chemistry preservative meet the needs of production healthy food. |
