Embodiment 1

[0027] The production method of the easily degradable edible food paper with the composite structure of old laver-loose enteromorpha layer:

[0028] 1) Cut Enteromorpha into short bundles of about 3-5 cm, wash and squeeze it 3 times with simple fresh water, put it in an ultrasonic cleaning tank, add 0.05% concentration of hydrogen peroxide solution, and ultrasonically clean for 3 minutes to find that the Enteromorpha is clean. It has a fresh seaweed taste, and the salt content is significantly reduced to no obvious salty taste when chewing. The microbiological test meets the food requirements.

[0029] 2) When the washed Enteromorpha is dried until it wilts but is not brittle, soak it in the gypsum solution for 12 hours and take it out to dry. During the drying process, the unbonded gypsum powder is washed away with a water gun, and it is dried until it is wilted but not brittle to obtain a nearly dry Enteromorpha. Moss, immediately put it in the cold storage for later use.

Embodiment 2

[0034] The production method of the easily degradable edible food paper with the composite structure of old laver-loose enteromorpha layer:

[0035] 1) Cut the Enteromorpha into short bundles of about 3 cm, wash and squeeze it twice with fresh water, put it in an ultrasonic cleaning tank, add 0.1% hydrogen peroxide solution, and ultrasonically clean it for 3 minutes, you can find that the Enteromorpha is clean and fresh The smell of seaweed does not turn yellow slightly, and the salt content is also significantly reduced to the point that there is no obvious salty taste when chewing. The microbiological test meets the food requirements.

[0036] 2) Dry the washed Enteromorpha until it wilts but is not brittle, soak it in the hot solution of calcium lactate for 12 hours, take it out and dry it, wash off the unbonded calcium lactate powder with a water gun during the drying process, and dry it until it is wilted but not brittle to obtain nearly Dried Enteromorpha, immediately pu...

Abstract

The invention discloses a production method of easily-degradable edible food paper of an old laver-loose enteromorpha composite structure. The production method includes: ultrasonically cleaning and degerming enteromorpha, soaking in calcium lactate or gypsum water solution, drying and removing calcium salt not bonded steadily on the surface, modifying treated enteromorpha to obtain a modified enteromorpha felt, compositing the modified enteromorpha felt with old laver containing calcium lactate in mesophyll for solidification, and drying to obtain the easily-degradable edible food paper of the old laver-loose enteromorpha composite structure. The problem of enteromorpha recycling is solved, and the easily-degradable edible food paper produced by the method is reliable in performance and has heat-insulating anti-impact functions.

Description

technical field [0001] The invention relates to the technical field of food packaging materials, in particular to a method for producing easily degradable edible food paper with a composite structure of old laver-loose enteromorpha layers. Background technique [0002] In seafood processing factories, usually a large amount of old laver after tail water is sold as feed laver powder at a low price, the price is as low as several thousand yuan / ton. Old seaweed is generally dark green and quite flexible. It swells after soaking / boiling in water but is difficult to chew. It is often reported as "fake seaweed made of plastic" and is generally considered unfit for consumption. Since its main component is laver gum, it cannot be industrialized by dissolving it with sodium hydroxide to produce alginic acid, and the degradation and extraction of agar also requires complicated alkali boiling-acid washing process, and there are not many resources at present. In the baking experiment, ...
