Description
Technical Field
The invention relates to the field of sticky food packaging technology, in particular to a preparation method of a sticky food packaging material prepared by edible wax fiberization treatment, namely, the anti-sticking packaging material special for sticky food is prepared by combining the high hydrophobicity of edible wax with an electrostatic spinning technology.
Background
Viscous foods are popular with consumers for a long time due to unique mouthfeel. However, sticky food is easy to stick on a package and is difficult to take out, and the sticky food is easy to stick hands in the eating process, so that a great deal of inconvenience is brought to consumers, and the sticky food is difficult to produce and sell as convenient food. With the fast pace of life, consumers have an increasing demand for instant convenience foods, and packages that are not easily adhered need to be invented in order to solve the problem of sticky foods.
Superhydrophobic coatings characterized by high water contact angles and low sliding angles have attracted considerable attention. To prepare superhydrophobic coatings, fluorinated compounds including perfluoroalkylsilanes and fluoroacrylic copolymers are often used. However, fluorinated compounds and their degradation by-products have potentially adverse environmental effects and may also present food safety hazards and are not suitable for use in food products. The most common safe hydrophobic material in food at present is edible wax, but the application in wax packaging is only limited to preparing wax coating, and the wax packaging does not have bending resistance, so that the application of the wax in viscous food packaging is limited.
Disclosure of Invention
The invention provides a preparation method of a viscous food packaging material, which solves the problem of poor bending resistance of the existing wax coating anti-sticking material through an electrostatic spinning technology.
The technical scheme of the invention comprises the following four steps:
the method comprises the following steps: grinding the granular edible wax solid into powder;
step two: mixing and co-melting an edible wax in powder form with polypropylene;
step three: adding hot water, uniformly mixing by using ultrasonic waves, and putting into an electrostatic spinning machine for fiberization;
step four: and spraying the spinning solution on an aluminum foil by using a spinning machine to prepare the viscous food packaging sheet.
The coating has excellent anti-stick and mechanical properties.
The specific implementation mode is as follows:
conditions of the experiment
The preparation method of the special hydrophobic package for the viscous food by using the food-grade wax and the polypropylene as spinning solutions comprises the following steps:
grinding 10-20 g of granular edible wax solid into powder, carrying out hot melt blending with 10-30 g of polypropylene at 200 ℃, adding 300 mL of hot water to prepare a 6-14% spinning solution, uniformly oscillating the suspension by using an ultrasonic cell crusher, carrying out ultrasonic power of 600W, treating for 1 h, filling the solution into an injector of a spinning machine, and spraying the spinning solution on a receiver aluminum foil by using the spinning machine to serve as a hydrophobic material.
Flexural strength testing was performed on an Instron1195 universal materials testing machine, english. The material used for the test was cut into 3 × 4 × 35(mm × mm) strips. The span was 30mm and the loading rate was 0.5mm/min as measured by three-point bending. Each data was tested on 3 bars and then averaged.
100 g of the sticky steamed bun was placed on a hydrophobic material and kept for 1 hour and weighed, and the sticky steamed bun was gripped with tweezers and weighed again, and the residual amount of the sticky steamed bun was calculated. The above experiment was repeated 3 times to obtain an average value.
Comparative mode 1:
the edible wax solid can be selected from candelilla wax, rice bran wax, carnauba wax and beeswax, and other experimental conditions are as follows: 10g of granular edible wax, 10g of polypropylene and 10% of spinning solution.
TABLE 1 anti-crease and anti-stick properties of packaging materials made of different edible waxes
The beewax is selected as the packaging material, so that the bending strength is maximum, and the residual quantity of the sticky steamed bun is minimum.
Comparative mode 2:
the weight ratio of edible wax to polypropylene was 1: 3, 1: 2, 1: 1, 2: 1 and 2: 1, and other steps and process conditions were the same as in comparative example 1.
TABLE 2 anti-crease and anti-stick properties of packaging materials made with different ratios of edible wax to polypropylene
When the ratio of the edible wax is large, the residual quantity of the sticky steamed bun is small, but the bending strength is poor, the two indexes are comprehensively analyzed, and the ratio of the edible wax to the polypropylene is selected to be 1: 1.
Comparative mode 3:
the concentration of the prepared spinning solution is 6-14%. Other steps and process conditions were the same as in comparative example 1.
TABLE 3 anti-bending and anti-sticking properties of packaging materials made with different concentrations of the spinning dope
The difference of the bending strength of the packing materials made of different concentrations of spinning solution is not significant (p> 0.05) but the amount of viscous bun remaining was significantly lower than the other experimental groups when the dope concentration was 10%, thus a dope concentration of 10% was selected.
Comparative example 4:
the electrospinning voltage is 30 kV-38 kV. Other steps and process conditions were the same as in comparative example 1.
TABLE 4 anti-bending and anti-sticking properties of packaging materials made at different electrospinning voltages
The packaging material prepared by the electrospinning voltage of 36 kV has the largest bending strength and the least residual quantity of sticky steamed bun.
Comparative example 5:
the spinning distance is 24-28 cm. Other steps and process conditions were the same as in comparative mode 1.
TABLE 5 anti-bending and anti-sticking properties of packaging materials made with different spinning pitches
The bending strength of the packaging material prepared by the spinning distance of 25 cm is the largest, and the residual quantity of the sticky steamed bun is the smallest.
