Embodiment 1
[0028] Embodiment one: the preparation of citrus / olive pomace paper film
[0029] (1) Select fresh citrus and olives with full grains, no signs of pest damage and rot, and pre-clean them with water jets to remove pesticides, dust, and sundries on the surface of the fruits, and then put them into the brush cleaning machine for 2~3 days. Second; use a squirrel cage crusher to crush until the particle size is 3-4cm, then squeeze the juice with a squeezer; use a shredder to finely chop the fruit pomace after the juice;
[0030] (2) Take 200g each of the two kinds of fruit pomace obtained in step (1) into a beater, add 200g of deionized water, 8g of sucrose, 1.2g of salt, 0.8g of five-spice powder, 3.6g of plantain and taro powder, and the modified wheat Gluten protein 2.4g, citric acid 1.6g, glycerin 5g, beating at room temperature at a speed of 1050r / min for 35min, and homogenizing twice through a colloid mill, so that the average particle size of pomace fiber molecules reaches 5...
Embodiment 2
[0035] Embodiment two: the preparation of navel orange / apple / snow pear residue paper type film
[0036] (1) Select fresh navel oranges, apples and snow pears with full grains, no signs of pest damage and rot, and pre-clean them with jet water to remove pesticides, dust and sundries on the surface of the fruits, and then put them into the brush cleaning machine for cleaning 2 ~3 times; use a squirrel cage crusher to crush until the particle size is 3~4cm, and then squeeze the juice with a squeezer; use a shredder to finely chop the juiced fruit pomace;
[0037] (2) Take 50g of each of the three types of fruit pomace obtained in step (1) in a beater, add 75g of deionized water, 4g of sucrose, 0.6g of salt, 0.7g of five-spice powder, 1.3g of plantain taro powder, and the modified wheat Gluten protein 1.1g, citric acid 0.6g, glycerin 2.1g, beating at room temperature at a speed of 1050r / min for 35min, and homogenizing twice through a colloid mill, so that the average particle size...

Abstract
The invention discloses an antibacterial marc paper-type edible packing film and belongs to the technical field of food package. The antibacterial marc paper-type edible packing film is characterizedin that under the condition of adding no chemical preservatives or bacteriostats, two or more marcs are taken as raw materials, blended, pulped, homogenized, film-formed after being deaerated, and dried to obtain an end product. Compounding and mixing are performed by use of the difference between functional ingredients of the two marcs; canna edulis ker powder and modified wheat gluten protein serve as forming agents; nylon filter cloth is taken as a film-forming medium; the antibacterial property and the edibility of the marc paper-type edible packing film are improved on the basis of guaranteeing the favorable film uncovering capability of the marc paper-type edible packing film; the problems that a conventional marc paper-type edible packing film cannot be stored for a long time due topoor antibacterial property and is short in shelf life are solved; and meanwhile, environmental pollution caused by marc waste is reduced.
Description
technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to an antibacterial fruit residue paper-type edible packaging film. Background technique [0002] As the fruit juice beverage market booms, so does a large amount of by-products including pomace, seeds, peels, pulp, unused pulp and husks. These residues are still rich in nutrients such as vitamins, minerals, organic acids, pectin and dietary fiber, and are indispensable foods in human diets. But at present, most of the processing methods for these residues are discarded or used as cheap feed. It is estimated that 300,000 to 67,000,000 tons of fruit and vegetable waste will be produced in the world every year. Therefore, the further development and utilization of fruit and vegetable residues has higher economic benefits and can reduce the harm of waste to the environment. At present, fruit residues are mainly utilized through the development of fruit residue pap...
