Embodiment 1

[0034]According to mass percentage, take 40% zein, 15% water, 30% ethanol, 5% glycerin, 8% oleic acid and 2% galactose respectively; after mixing water and ethanol, add glycerin, mix well at room temperature, Add oleic acid, mix well, heat to 40°C, then add galactose to obtain a mixed solution; add the mixed solution to zein under stirring conditions, and stir at 75°C for 10 minutes , fully homogeneous, cooled naturally to room temperature to form a resinous substance; using the rotary extrusion method, the resinous substance is extruded under the conditions of an extrusion pressure of 20 MPa and an extrusion outlet temperature of 50 ° C, so that it is rotated and overlapped and interwoven into a A semi-finished tubular casing with a caliber of 16 mm and a film thickness of 30 μm; according to the volume ratio of 1:1, take a sodium chloride solution with a concentration of 4% and a calcium chloride solution with a concentration of 1% to make a solidified solution; put the semi-...

Embodiment 2

[0037] According to the mass percentage, take 60% zein, 10% water, 20% ethanol, 6% glycerin, 3% oleic acid and 1% galactose respectively; after mixing water and ethanol, add glycerin, mix well at room temperature, Then add oleic acid, mix well, heat to 45°C, then add galactose to obtain a mixed solution; add the mixed solution to zein under stirring conditions, and stir at 70°C for 15 minutes , fully homogeneous, naturally cooled to room temperature, forming a resinous substance; using the rotary extrusion method, the resinous substance is extruded under the conditions of an extrusion pressure of 30Mpa and an extrusion outlet temperature of 45°C, so that it rotates and overlaps and interweaves into a A semi-finished tubular casing with a diameter of 30 mm and a film thickness of 35 μm; according to the volume ratio of 4:1, take a sodium chloride solution with a concentration of 8% and a calcium chloride solution with a concentration of 1.5% to make a solidification solution; pu...

Embodiment 3

[0040] According to mass percentage, take 50% zein, 11% water, 25% ethanol, 7.5% glycerin, 5.5% oleic acid and 1% galactose; mix water and ethanol, add glycerin, and mix well at room temperature , then add oleic acid, after mixing, heat to 50°C, and then add galactose to obtain a mixed solution; add the mixed solution to zein under stirring conditions, and stir at a temperature of 72.5°C for 12.5 Minutes, fully homogeneous, naturally cooled to room temperature, forming a resinous substance; using the rotary extrusion method, the resinous substance is extruded under the conditions of extrusion pressure 25MPa and extrusion outlet temperature 40°C, so that it rotates, overlaps and interweaves A semi-finished tubular casing with a caliber of 25 mm and a film thickness of 40 μm; according to the volume ratio of 2.5︰1, take a sodium chloride solution with a concentration of 6% and a calcium chloride solution with a concentration of 2% to make a solidification solution; the semi-finis...

Abstract

The invention provides a method for producing an edible corn protein casing, which takes zein, water, ethanol, glycerol, oleic acid and galactose as raw materials; after water and ethanol are mixed, the glycerol and the oleic acid are added, heating is carried out, the galactose is then added, so the mixed solution is obtained; the mixed solution is added into the zein under the stirring condition, is stirred at a certain temperature, fully homogenized, and naturally cooled to the room temperature, so a resin-shaped material is formed; a rotary extrusion method is adopted to extrude the resin-shaped material, so the resin-shaped material is rotated, superposed and intertwined into a tubular casing semi-finished product; and the tubular casing semi-finished product is solidified, dried at a certain temperature, then flattened, wound, formed and produced into the edible corn protein casing.. The method for producing the edible corn protein casing takes the zein as a raw material, the edible plant protein casing with high edible safety is produced under the condition of not using a cross-linking reagent, so the defects of the shortage of natural casing raw material sources and the easily-influenced quality safety of the collagen casing due to animal epidemic diseases and other factors are made up.

Description

technical field [0001] The invention belongs to the technical field of casing processing, and relates to a method for preparing vegetable protein casings, in particular to a method for preparing edible protein casings by using zein as a main raw material. technical background [0002] The sausage casing is a product suitable for human consumption obtained by scraping the large and small intestines of livestock. It is mainly used for filling sausages and is the coat of sausages. Natural casings have limited sources of raw materials, many bends, and uneven strength. The manual operation is arduous and laborious when processing casings, and the added value of product technology is low. Moreover, animal collagen casings are made of animal leather, and the quality and safety are easily affected by factors such as animal epidemics. . [0003] Corn is one of the three major food crops in the world and is widely used to produce starch. Zein is a by-product of corn processing, rich...
