Technical Field

The invention relates to the field of disposable tableware and lunch boxes, in particular to disposable edible environment-friendly tableware and lunch boxes

Background

Disposable tableware and lunch boxes are disposable dining utensils, are used in large quantities at present and are mostly made of non-degradable plastics, so that not only is resource waste caused, but also the environment is seriously polluted.

Disclosure of Invention

In view of the above problems, the present invention aims to provide a disposable edible environment-friendly tableware and a production process thereof, wherein the material is made of edible starch, and the tableware is edible after use, so that pollution is reduced.

The invention relates to a disposable edible environment-friendly tableware and a production process technology thereof.

Further, the material preparation comprises mixing the raw starch and the edible crude fiber according to the ratio of 5: 1, adding 35% of water, and uniformly mixing.

Furthermore, the mixture is placed in a meal box and tableware mould for shaping.

Further, the mold filled with the mixture was placed in an autoclave and steamed for 30 min.

Further, the steamed mixture is demoulded and placed below 0 ℃ for rapid cooling.

Further, a calcium lactate solution is prepared by adding 0.1% -0.3% calcium lactate to edible water.

Further, sodium alginate solution is prepared by adding 1% sodium alginate into edible water.

Furthermore, the film forming method is that the formed lunch box and tableware are firstly put into sodium alginate solution for a few seconds and then put into calcium lactate solution for film forming.

Furthermore, the film-formed lunch box and tableware are quickly air-dried at high temperature.

Furthermore, the structure of the lunch box is that the middle layer is made of starch and crude fiber mixture, and the inner layer and the outer layer are both made of edible films.

Furthermore, the tableware has a structure that the middle layer is made of starch and crude fiber mixture, and the outer layer is made of edible film.

Furthermore, the manufacturing method can be used for disposable lunch boxes and tableware such as spoons, chopsticks and lunch boxes.

After the technical scheme is adopted, compared with the prior art, the invention has the following beneficial effects.

The invention is composed of an inner layer, an outer layer and an intermediate layer, wherein the intermediate layer is a transparent solid which is formed by decocting starch, edible crude fiber and water and drying in the air after shaping, and the outer layer of the inner layer is a waterproof film which is prepared by reacting a sodium alginate aqueous solution and a calcium lactate aqueous solution and completely wraps the inner layer, so that the waterproof film is not easy to damage by water and oil. The disposable environment-friendly tableware disclosed by the technology of the invention is edible, environment-friendly, low in cost, pollution-free and suitable for being used as a substitute of plastic tableware and lunch boxes. The invention has simple structure and obvious effect and is suitable for popularization and use.
