specific Embodiment approach 1

[0015] Specific embodiment 1: In this specific embodiment, the high tensile strength Platycodon grandiflorum edible film is composed of 2.0%-3.0% (by weight) Platycodon grandiflorum polysaccharide extract, 2.5%-3.0% sodium alginate, 1.5%-2.0% glycerin and 80% %-95% solvent forms a molding solution, which is stirred, degassed, film-laid, and dried to form an edible film of 0.05-0.2mm.

specific Embodiment approach 2

[0016] Specific embodiment two: this specific embodiment is different from specific embodiment one in that every 100 grams of high tensile strength edible platycodon film contains 2.16 grams of platycodon grandiflorum polysaccharide. Others are the same as the first embodiment.

specific Embodiment approach 3

[0017] Specific embodiment three: In this specific embodiment, a high tensile strength Platycodon grandiflorum edible film is prepared according to the following steps:

[0018] 1) Preparation of Platycodon grandiflorum polysaccharide powder: select dried Platycodon grandiflorum rhizomes, pulverize, add Platycodon grandiflorum powder and aqueous solution at a ratio of 1g:30mL~1g:50mL, soak for 1h, and then act on 400~500W microwave for 3~4min. , 70 ℃ water bath for 60 minutes, get the platycodon grandiflorum polysaccharide extract, use a decanter centrifuge at a speed of 1500 ~ 2000r / min for solid-liquid separation, separate the extract and residue, 45 ~ 55 ℃ vacuum rotator to concentrate the extract, and then Add three times the volume of 70% to 90% ethanol solution to the extract, separate the alcohol precipitation, and freeze-dry in vacuum to obtain Platycodon grandiflorum polysaccharide powder.

[0019] 2) The prepared Platycodon grandiflorum polysaccharide powder, sodium algin...

Abstract

The invention provides a high-tensile strength platycodon edible film and a preparation method thereof, and relates to a platycodon edible film product and a preparation method thereof. The preparation method of the high-tensile strength platycodon edible film comprises the following steps of: preparing moulding solution with 2.0%-3.0% (weight) of platycodon polysaccharide extractive, 2.5%-3.0% of sodium alga acid, 1.5%-2.0% of glycerol and 80-95% of dissolvent; stirring; degassing; paving a film; and drying to obtain the high-tensile strength platycodon edible film with 0.05-0.2mm. Specifically, the preparation technology of the high-tensile strength platycodon edible film comprises the following steps of: selecting the dried root of the platycodon; degreasing the smashed powder; extracting the polysaccharide extractive from the platycodon through a microwave auxiliary extraction method; separating the extracting liquid with an ultracentrifuge; concentrating with a vacuum rotary evaporator; drying in a freeze way with a vacuum freeze dryer to obtain freeze-drying powder of the platycodon polysaccharide extractive; matching the freeze-drying powder with proper amount of intensifier and plasticizer to prepare film liquid; stirring; degassing; paving a film; and drying to obtain the platycodon edible film with better tensile strength.

Description

Technical field [0001] The invention relates to an edible film of Platycodon grandiflorum and a preparation method thereof. Background technique [0002] Platycodon grandiflorum polysaccharide is a rich component in the rhizome of Platycodon grandiflorum. In addition to the immune function, anti-tumor and anti-aging effects of polysaccharides, it also has film-forming properties. After adding related materials, it can be produced with high resistance. Edible film with tensile strength. It can be used in packaging fields such as food, health products, cosmetics, medicine, biochemical industry, etc. [0003] For the edible film of Platycodon grandiflorum with high tensile strength, it can be widely used in the packaging market of food, medicine, health care products and cosmetics. The edible film prepared from Platycodon grandiflorum polysaccharide has higher tensile strength and edibility. The market prospects for edible packaging are very broad. Although there are many researche...
