Problems solved by technology

However, there are not many studies on the development and utilization of Enteromorpha, so the rich Enteromorpha biological resources have not been fully utilized
Especially in 2008, after the large-scale outbreak of Enteromorpha disaster in Qingdao coast and adjacent sea areas, the whole society urgently used a lot of manpower and material resources to salvage Enteromorpha, and most of the salvaged Enteromorpha were discarded and rotted, resulting in waste of resources and environmental pollution
[0003] In the face of precious resources

Embodiment 1

[0022] The present invention will be further illustrated in combination with the implementation process example:

[0023] Enteromorpha 100g and 10g NaHCO 3 →Add 1300ml of water and boil the glue at a constant temperature of 90°C for about 1 hour→16 layers of gauze filtration→polysaccharide infusion→add 0.3% phospholipid, 0.5% modified starch, 1% CMC, 0.3% glycerin in sequence→stir evenly, adjust pH value to neutral → 60°C water bath for 30min → pumping → respectively pour 10ml on a glass sensor with a diameter of 16 → 25±0.5°C, relative humidity 50±5%, and place for 24h → peel off the film.

Embodiment 2

[0025] Enteromorpha 100g and 10g NaHCO 3 →Add 1300ml of water and boil the glue at 95℃ for about 1 hour → Filter with 16 layers of gauze → Polysaccharide infusion → Add 0.2% phospholipid, 0.5% modified starch, 1% CMC, 0.2% glycerin in sequence → Stir evenly, adjust pH value to neutral → 60°C water bath for 30min → pumping → respectively pour 10ml on a glass sensor with a diameter of 16 → 25±0.5°C, relative humidity 50±5%, and place for 24h → peel off the film.

Abstract

The invention discloses a preparation method and an application of an edible food packaging film taking sea grass polysaccharide as a substrate. The technological technique comprises the following steps: adopting hot water and sodium hydroxide to leach sea grass polysaccharide, preparing a certain amount of sea grass polysaccharide immersion liquid phospholipid, modified starch, CMC, glycerol, gelatin and the like into filming liquid, reacting for a certain time at a proper temperature, reversely putting the filming liquid after air exhaust in a tray with a rim, drying, taking off a film and preparing an edible film. The invention provides a novel approach for the high-value utilization of sea grass; the technique is scientific, reasonable, simple and practicable and has low cost; and the edible film has favorable extensibility, tensile strength and anti-oxidation function and is semitransparent. A product is safe and effective, has no toxic or side effect, has double actions of packaging and nutrition and has extensive market prospect.

Description

Technical field [0001] The invention relates to a preparation method and application of an edible food packaging film with Enteromorpha polysaccharide as a matrix, and belongs to the technical field of food processing. Background technique [0002] Enteromorpha is a seaweed with abundant resources along the coast of my country. There are factories for artificially cultivating Enteromorpha in the coast of Zhejiang, and the Enteromorpha is produced for food and feed. As early as ancient times, Chinese medicine and folk experience recognized that Enteromorpha not only has rich nutritional value, but also has health effects such as clearing away heat and detoxifying, anti-bacterial and anti-inflammatory, lowering cholesterol, and enhancing immunity. In recent years, there have been in-depth studies on the biological characteristics and biological activities of Enteromorpha at home and abroad. However, there is not much research on the development and utilization of Enteromorpha, so ...
