Abstract

The invention discloses alginate co-extruded enteric coating glue, a preparation method therefor and an obtained co-extruded enteric coating. The enteric coating glue disclosed comprises alginate compound glue and a calcium suspension, wherein the alginate compound glue is an aqueous solution of alginate compound powder, the alginate compound powder comprises 65%-75% of alginate, 5%-10% of thickener, 1%-5% of emulsifier, 10%-20% of protein and 5%-15% of chelant, and a concentration of the alginate compound glue is 5%-10%; and a mass ratio of the alginate compound glue to the calcium suspensionis (20: 1) to (30: 1), and the calcium suspension comprises 30%-40% of micro-soluble calcium salt, 15%-25% of chelant and 40%-55% of vegetable oil. The invention further discloses the preparation method for the enteric coating glue and the co-extruded enteric coating obtained by the enteric coating glue. All raw materials of the enteric coating glue disclosed by the invention interact and promotemutually, the enteric coating obtained by the enteric coating glue has good tensile strength, low water vapor permeability and stable performance, and thus, the enteric coating glue has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of food packaging, in particular to an alginate co-extruded casing glue, a preparation method thereof and the obtained co-extruded casing. Background technique [0002] Sausage is a very special food, which must be packaged with casings made of natural raw materials; at present, the most commonly used casings are collagen casings. Co-extrusion technology is an important technological innovation in the sausage processing industry. It does not need to stop the machine to load pre-processed casings, but uses co-extrusion casing equipment to continuously separate the meat and casing gel from the inner and outer casings of concentric circles. Squeeze out and finally solidify into sausages. The casing formed by this method has strong toughness, can wrap the stuffing firmly, and is a green, healthy and edible food packaging film. [0003] In the prior art, the gel of the casing is used to obtain the casing throug...
