specific Embodiment

[0031] A kind of preparation method of antibacterial and fresh-keeping juicy peach growth bagging of the present invention specifically comprises the following steps:

[0032](1) Preparation of water-resistant agent: add 80-160 parts of paraffin and 10-40 parts of stearic acid into the reactor by mass parts, add 2-10 parts of borax and 1-6 parts of stearic acid after heating to 60-100 °C KOH, after stirring evenly, add 1200-2700 parts of water to dilute, then stir at 50-80°C for 0.5-3h;

[0033] (2) Pulp mixing: the natural color coniferous wood pulp and waste newspaper are beaten separately and mixed with equal quality to obtain a mixed pulp. The mixed pulp is added to the blending pool, and 10% of the mass of the mixed pulp is added to the mixed pulp in the blending pool. China clay, Cationic disperse rosin gum with 1% mass of mixed pulp, water-resistant agent with 5% mass of mixed pulp, wet strength agent with 3% mass of mixed pulp, and industrial aluminum sulfate with 5% m...

Embodiment 1

[0040] Add 120 parts of paraffin and 25 parts of stearic acid into the reactor in parts by mass, add 6 parts of borax and 4 parts of soda ash after heating to 80°C, stir well, add 1600 parts of water to dilute, and then stir at 65°C for 1.5h Prepare the anti-water agent; 50kg natural softwood pulp and 50kg waste newspapers are beaten respectively and mixed to obtain a mixed slurry, which is poured into the blending tank, and 10kg of china clay, 1kg of cationic disperse rosin gum, and 5kg of anti-aging agent are added to the mixed slurry. Water agent, 3kg of wet strength agent and 5kg of industrial aluminum sulfate are stirred evenly to obtain a slurry; the slurry is formed by the wire part, pressed and dehydrated, then dried at 100°C, then coiled and made into paper, and the waterproof layer is obtained. For bagging paper, the amount of slurry per square meter of bagging paper is 48g.

[0041] Add 3.5kg of carrageenan and 1L of Tween-60 into 100L of water and heat, and stir u...

Embodiment 2

[0043] Same as Example 1, the difference is: 80 parts by mass of paraffin wax in the anti-water agent, 40 parts of stearic acid, heating temperature of 60°C, 2 parts of borax, 6 parts of soda ash, after stirring evenly, add 1200 parts of water to dilute, heat at 50°C Stirring time is 3 hours; the amount of bagging paper is 45g of slurry per square meter of bagging paper; 2kg of carrageenan, 0.1kg of wormwood essential oil, 10kg of chitosan, and 20% of fenvalerate (EC) in the compound gel 0.001L.

[0044] Apply the compound gel on the inner surface of the fruit bagging paper with a waterproof layer, and the amount of gel application is 60g / m 2 , 1000m 2 The bagging paper needs to be sprayed with 60kg compound gel. Finally, cut the paper into a size of 30cm×30cm to make a paper bag.

Abstract

The invention discloses an antibacterial fresh-keeping juicy peach growth bag and a manufacturing method of the antibacterial fresh-keeping juicy peach growth bag. The manufacturing method of the antibacterial fresh-keeping juicy peach growth bag is characterized by comprising the steps that paraffin and stearic acid are added in a reactor, borax, sodium carbonate and water are added after the paraffin and the stearic acid are heated, and a water repellent agent is obtained through stirring; natural color softwood pulp and waste newspapers are respectively pulped and then are mixed to obtain mixed pulp, and china clay, positive ion scattered rosin size, the water repellent agent, a wet strength agent and industrial aluminum sulfate are respectively added into the mixed pulp to obtain a novel pulp; after the operations of net forming, squeezing, dewatering and drying are carried out on the novel pulp, the processed pulp can be reeled up into paper; after water is added to carrageenan and Tweens-60, the carrageenan and the Tweens-60 are heated, stirred and uniformly mixed until the carrageenan is melt, wormwood essential oil, chitosan, fenvalerate 20%( missible oil) and benzoic acid are added in sequence and evenly mixed, and compositional gel is obtained after the mixed solution is cooled and solidified; the compositional gel is coated on the inner surface of bag paper with a waterproof layer, and a finished product is obtained after drying and cutting. The antibacterial fresh-keeping juicy peach growth bag has the advantages of preventing pests, preventing mould, being antibacterial, keeping fresh, and prolonging the shelf life of juicy peaches.

Description

technical field [0001] The invention relates to a fruit bagging technology and a production method thereof, in particular to an antibacterial and fresh-keeping peach growth bagging technology and a production method for preventing peaches from being damaged by insects and mildew during the growth period. Background technique [0002] Peach is rich in nutrition. It is famous for its tender and juicy meat, rich and mellow taste, sweet and sweet, and its taste is very tender and smooth. Peach, rich in iron, can increase the amount of hemoglobin in the human body. Peach flesh can nourish blood and beautify the face. It is one of the main fruits in our country in summer. With the improvement of people's living standards, people's requirements for peaches have turned to high quality and pollution-free. The price of commercially available pollution-free peaches is significantly higher than that of ordinary fruits, and the production of pollution-free peaches depends on whether frui...
