Problems solved by technology

Plastic packaging film is widely used, but it is easy to produce harmful gas and peculiar smell; and plastic packaging film is not easy to decompose, causing "white pollution" and causing environmental pollution
Foods packaged in glutinous rice paper packaging film are edible, but their strength is poor, and they are easily damaged and dissolved by moisture when exposed to water. They are not suitable for automatic food packaging machinery operations, and it is still difficult to meet the needs of food packaging

Embodiment Construction

[0018] An edible packaging film with wheat dietary fiber as a matrix and a preparation method thereof, the process steps are:

[0019] 1) Pulverization: Send the wheat into a pulverizer for pulverization, and pass through a 50-100 mesh sieve to obtain wheat granules;

[0020] 2) Dissolution: Dissolve wheat grains in water, and adjust the pH value to 11~12 with 5% sodium hydroxide solution;

[0021] 3) Heating: Heat the adjusted solution to 45°C, heat at constant temperature for 5-10 minutes, heat to 70°C, keep warm for 20-40 minutes, and cool to 30°C;

[0022] 4) Enzymolysis: adjust the pH value of the heated solution to 6~6.5 with acidic substances, add papain with a weight ratio of 1%~2%, keep stirring and keep warm for 2~3 hours;

[0023] 5) Superfine pulverization: Use a superfine pulverizer to pulverize the extracted wheat dietary fiber for 30-40 minutes; pass through a 120-150 mesh sieve and collect;

[0024] 6) Stirring: Stir the sieved wheat dietary fiber for...

Abstract

The invention relates to a food packaging film and a preparation method thereof, and particularly relates to an edible food packaging film using wheat dietary fiber as a substrate and a preparation method thereof, belonging to the field of food packaging. The edible food packaging film has good barrier performance and fine mechanical properties, and can be used for preparing inner packaging materials of various foods. Besides, the edible food packaging film does not change the appearance and flavor of the food, can be eaten together with the food, and can not generate harmful gas and peculiar smell and cause white pollution, thereby avoiding environmental pollution.

Description

[0001] technical field [0002] The invention relates to a food packaging film and a preparation method thereof, in particular to an edible food packaging film with wheat dietary fiber as a matrix and a preparation method thereof, belonging to the field of food packaging. Background technique [0003] The preservation of food depends on the packaging of the food and its barrier to the outside world. Plastic packaging film is widely used, but it is easy to produce harmful gas and peculiar smell; and plastic packaging film is not easy to decompose, causing "white pollution" and causing environmental pollution. Although the food packaged in glutinous rice paper packaging film is edible, its strength is poor, and it is easily damaged by moisture and dissolved in water, and it is not suitable for automatic food packaging machinery operation, and it is still difficult to meet the needs of food packaging. Contents of the invention [0004] In view of the problems in the prior ar...
