Description
Technical field
The present invention relates to food packaging applications, a kind of edibility carragheen-sodium alginate film and its preparation are specifically provided
Method.
Background technique
In recent years, there is also many potential danger while the life to people brings great convenience for plastic package material
Evil.Studies have shown that it is by polymer chemistry object that the material of the food packaging generally used in daily life, which is mainly plastic products,
Matter is processed and is formed, and the chemical property stabilization of raw material will not be detrimental to health, but the additive in production plastics
Or the dangerous substance generated under the influence of working condition, then food even health generation can be seriously affected, meanwhile,
It is not easily decomposed rotten feature and results in serious environmental pollution.
With the great attention to packaging material for food safety, every country to the inlet and outlet of packaging material for food all into
Very strict control is gone, currently, edible film has done the hot spot of every country research.Edible film is with edibility natural material system
It is standby to form, by the barrier property of film itself, the influence that food receives external environment is prevented and treated, guarantees the quality of food, usual root
Classify according to the material difference for preparing edible film: polysaccharide edible film, protein edible film and compound edible film etc..Mesh
Before, studies have shown that edible film can partially replace the plastic film to be to effectively reduce pollution on the environment degree
A kind of environmentally friendly packing material with development prospect.
Summary of the invention
The present invention is directed to many shortcomings of the existing technology, provides a kind of edibility carragheen-sodium alginate
Film and preparation method thereof, edibility be using carragheen as primary raw material, into its solution be added sodium alginate, tangerine oil and
Glycerol is made the colloidal solution of stable homogeneous, then by degassing, pour mask, dry, take off film and form.It can be widely applied to fresh agriculture
The packaging of product, the packaging of high oil food, other oxidizable products the packaging applications neck such as packaging, shopping bag for supermarket, refuse bag
Domain.
The specific technical solution of the present invention is:
A kind of edibility carragheen-sodium alginate film, a kind of preparation method of edibility carragheen-sodium alginate film, tool
Body includes the following steps:
