Embodiment

[0019] (1) Preparation of horse-faced puffer fish skin gelatin: Greenfin horse-faced fish ( Thamnaconus modestus ) Fish skin was minced, added to 1mol / L NaOH solution according to the ratio of material to liquid 1 g: 10 mL, stirred for 7 h, washed with double distilled water until neutral; then added to 0.5% Soak in HCl at room temperature for 3 days, and change the water once every 12 h; finally, homogenate the treated fish skin, add it into double distilled water according to the ratio of solid to liquid 1 g: 12 mL, extract dynamically at 65 °C for 12 h, and then Centrifuge at 9 000 g for 15 min, take the supernatant, concentrate, and freeze-dry to obtain horse-faced puffer fish skin gelatin.

[0020] (2) Preparation of chitosan nanospheres: Chitosan was added to 1% glacial acetic acid solution according to the ratio of solid to liquid 1g: 80 mL, stirred at room temperature overnight to make it completely dissolved, and the chitosan solution was filtered through a 0.8 μm...

Abstract

The invention discloses a thamnaconus modestus fish skin nanoparticle composite edible membrane which comprises the following components in parts by weight: 33-40 parts of gelatin, 0.65-1.2 parts of porphyra haitanensis antioxidant, 6.5-1 part of plasticizer and 55-60 parts of chitosan microsphere. The technology comprises the steps of preparing thamnaconus modestus fish skin gelatin, preparing chitosan nanoparticle and preparing porphyra haitanensis antioxidant, then preparing the prepared gelatin, chitosan nanoparticle and porphyra haitanensis antioxidant into a solution, and preparing a film-forming solution by the addition of the plasticizer, finally pouring the prepared film-forming solution on a polyvinyl chloride crystal board for striking, drying and film uncovering to obtain the antioxidant gelatin-chitosan nanoparticle composite edible membrane. The invention takes the thamnaconus modestus fish skin as the main raw material, so that a new approach for high-value use of the thamnaconus modestus processing leftovers is established; the prepared antioxidant gelatin-chitosan nanoparticle composite edible membrane has remarkable antioxidant activity and seaweed flavor.

Description

technical field [0001] The invention belongs to the technical field of food quality and safety, and relates to a functional edible film, in particular to a composite edible film of horse-faced puffer fish skin nano microspheres. Background technique [0002] In recent years, with the improvement of people's living standards and the enhancement of environmental awareness, the environmental problems caused by plastic packaging materials prepared from non-renewable resources have received more and more attention. Research hotspots. Among the many renewable biomaterials, biofilm research using proteins from various sources (such as soybean protein, whey protein, casein, corn protein and wheat protein) has received extensive attention. , strong film-forming ability and good biocompatibility have become research hotspots. [0003] At present, animal gelatin is mainly prepared from raw materials such as skins, tendons and bones of livestock products such as pigs and cattle. Ho...
