Problems solved by technology

With the improvement of detection technology, toxic and harmful carcinogens in plastic packaging films have been continuously detected. Plastic packaging films not only cause white pollution to the environment, but also bring new hazards to people's bodies
At present, the common edible glutinous rice paper packaging film on the market has relatively limited application due to its poor tensile performance. It is only used in the field of candy packaging, and the raw material is relatively single, so it is difficult to bring large social benefits. Related edible packaging has also been researched or developed in the market, but it contains certain chemical components, such as edible glue, pigment, etc., so it is urgent to invent a low-carbon concept, which has wider uses and is as effective as the packaged food raw materials.

Embodiment 1

[0022] The amount of formula, by weight: 68 parts of wheat flour, 3 parts of sucrose, 8 parts of drinking water, 9 parts of vegetables, 12 parts of eggs. Among them, vegetables are one or two or more of spinach, celery, carrots and tomatoes. Complete according to the following process:

[0023] Prepare the main ingredient, mix the formula amount of wheat flour and formula amount of water to form a paste;

[0024] Prepare auxiliary materials, squeeze vegetables into vegetable juice with appropriate amount of water, and blend the formula amount of sucrose with vegetable juice;

[0025] Prepare a coagulant, and evenly break up the formulated eggs;

[0026] Mix the above-mentioned raw materials and slowly pour them into a grinding device and grind them into a paste, so that the particle size of the paste is above 200 mesh;

[0027] The above-mentioned paste is used to form a film on a film forming machine.

[0028] Film making machines include roller film making machines and metal belt fil...

Embodiment 2

[0036] The amount of formula, by weight: 55 parts of wheat flour, 3 parts of sucrose, 3 parts of drinking water, 3 parts of vegetables, 5 parts of eggs. Among them, vegetables are one or two or more of spinach, celery, carrots and tomatoes. The edible packaging film was prepared according to the process of Example 1. After testing, the data in Table 2 is obtained.

Abstract

The invention discloses an edible package film, a preparation method and the usage thereof. The edible package film comprises 50-85 parts by weight of flour, 2-10 parts by weight of sugar, 2-10 parts by weight of vegetable, 5-15 parts by weight of eggs and 2-10 parts by weight of water. The edible package film is prepared by mixing and grinding the raw materials according to the proportion into paste. The edible package film has the appearance which is similar to a plastic film, can be dissolved in the water with 70-100 DEG C, is edible, can be used for making inner package material of various foods, packaging part of medicines, and the like, is harmless for human body and has a certain nutritional value. The edible package film has instant solubility, can be dissolved when coming across heat and melted when coming across water, and can maintain good mechanical performance when not coming across heat and water. Furthermore, the invention has simple technique and low manufacturing cost.

Description

Technical field [0001] The invention relates to an edible packaging film and its preparation method and application. Background technique [0002] At present, most of the food packaging on the market mainly uses plastic packaging film. With the improvement of detection technology, toxic and harmful carcinogens in plastic packaging films have been continuously detected. Plastic packaging films have not only caused white pollution to the environment, but also brought new harm to people's bodies. At present, the common edible glutinous rice paper packaging film on the market, due to its poor tensile properties, has a relatively large use limit. It is only used in the field of candy packaging, and the raw material is relatively single, which is difficult to bring big social benefits. Related edible packaging has also been researched or developed on the market, but it contains certain chemical ingredients, such as edible gums, pigments, etc., so there is an urgent need to invent a lo...
