Food package film containing lacquer tree seed extract

Abstract

The invention discloses a food package film containing a lacquer tree seed extract. The food package film is prepared by the following steps of respectively dissolving a certain amount of polysaccharides, mixing, and adding an enhancer, the lacquer tree seed extract and other additives; performing heat preservation, homogenizing, degassing, and quantitatively demolding; finally, drying, so as to obtain the food package film with certain strength and water solubility. The food package film has the advantages that the technology is simple, the industrialization is easy, the cost is low, the film forming property is good, the strength is high, and the formed film has certain wet blocking, oxygen blocking, oil blocking and solute blocking properties; the prepared food package film can be applied into the fresh-keeping of fruits and vegetables, processing and fresh-keeping of meats and aquatic products, internal package of instant foods or fast foods, and storage and package of sugars and baking foods.

Description

technical field [0001] The invention belongs to the field of food inner packaging materials, and is particularly suitable for food packaging films containing sumac seed extract. Background technique [0002] In the field of food packaging, compared with other paper and plastic packaging, the food packaging film containing sumac seed extract has incomparable advantages. It has the characteristics of edible, hygienic, environmental protection, and convenience. However, due to the limitation of traditional technology and formula, there are some limitations in the prepared edible packaging film, such as: the process route is relatively complicated, which makes it difficult to promote and utilize in industrialization; As a result of the increase in cost, it is difficult for manufacturers to accept it under the premise that the profit margin of the current food industry is generally not high; the prepared film has insufficient strength, poor heat sealability, low transparency, and...
