Problems solved by technology

The use of polysaccharides to modify the blended edible film has little research at home and abroad. The main reason is that in the current film-forming process, the addition of polysaccharides is mainly based on direct addition, which makes the performance of the formed film not significantly improved.

Embodiment 1

[0013] Example 1: Soy protein isolate and carrageenan were mixed at a mass ratio of 10:1, and ionized water was added to prepare a solution with a concentration of 30 g / L. Adjust the pH to 9, heat at 90°C for 30 min, add to the mixture of 0.1% lauric acid and 0.3% glycerin melted at 80°C, stir at 80°C, 10000 r / min for 1 min, and cool down. Vacuum degassing, spread the film-forming solution on a glass plate according to 50ml / m2, and place it in a drying oven at 30-50 ℃ and a relative humidity of 40%. Dry, form a film, and get it.

Embodiment 2

[0014] Example 2: Soy protein isolate and pectin were mixed at a mass ratio of 20:1, and ionized water was added to prepare a solution with a concentration of 50 g / L. Adjust the pH to 9, heat at 80°C for 30 min, add to the mixture of 0.1% beeswax and 0.3% glycerin melted at 80°C, stir at 80°C, 10000 r / min for 1 min, and cool. Vacuum degassing, spread the film-forming solution on a glass plate at 50ml / m2, and place it in a drying oven at 40°C and a relative humidity of 50%. Dry, form a film, and get it.

Embodiment 3

[0015] Example 3: Soy protein isolate and propylene glycol alginate were mixed in a mass ratio of 10:1, and ionized water was added to prepare a solution with a concentration of 30-50 g / L. Adjust the pH to 9, heat at 100 °C for 30 min, add to the mixture of 0.1% lauric acid and 0.3% glycerin melted at 80 °C, stir at 80 °C, 10000 r / min for 1 min, and cool. Vacuum degassing, spread the film-forming solution on a glass plate according to 50ml / m2, and place it in a drying oven at 45°C and a relative humidity of 45%. Dry, form a film, and get it.

Abstract

The invention relates to a preparation method of blending type tobacco sheets. the preparation method includes steps of: mixing isolated soybean protein and polysaccharide by mass ratio of 10-20:1, adding ionized water, preparing solution with concentration of 30-50g / L, adjusting the pH value to 9, heating to 80-100 DEG C for 30 minutes, then adding to melted the mixture of 0.1% of lauric acid (or beewax) and 0.3% of glycerol in 80 DEG C, stirring 10000r / min under 80 DEG C for 1 minute, cooling, vacuum-degassing, and then paving film-formed liquid on a glass plate 50ml / square meter, cooling until 30-50 DEG C, placing the film-formed liquid in a drying box with relative humidity of 40%-50%, drying, forming film, and obtaining the blending type tobacco sheets. The polysaccharide is propylene glycol alginate, pectin, carrageenan, aloe polysaccharide or other mixtures. The preparation method has the advantages that compared with traditional blending type tobacco sheets, the blending type tobacco sheets obtained through the preparation method are superior in barrier property and mechanical performance, and the application value of the blending type tobacco sheets is improved to a certain extent.

Description

Technical field: [0001] The invention relates to the field of preparation of tobacco sheets, in particular to the field of preparation of blended tobacco sheets. technical background: [0002] Tobacco sheet, also known as recombined tobacco, has similar physical and chemical properties to tobacco. Blending proteins and lipids can improve the physical properties of tobacco sheets, especially water resistance, but there are still major defects in mechanical properties, appearance properties, and barrier properties, which limit the use of blended film liquids in tobacco sheets and food. Application in preservation. Blending polysaccharides with proteins and lipids and optimizing the blending form can make the formed blended tobacco sheets complement each other in performance. [0003] The thickening and gelation of polysaccharides in the liquid phase make the blended film liquid more excellent and the film-forming liquid more stable. The use of polysaccharides to modify ...
