Problems solved by technology

[0003] At present, traditional edible moisture-proof films are made of glucose, starch and other mixtures through high-temperature injection molding. They have the following deficiencies: first, the problem of antibacterial properties. Traditional edible moisture-proof films are not antibacterial and easy to mildew; second, the moisture resistance of the film Performance and plasticity problems. At present, adding starch components is generally used to improve the moisture-proof performance of food and maintain food quality. However, starch quickly gelatinizes after absorbing water, which reduces the strength of edible moisture-proof films.
[0005] After searching the existing technical literature, it is found that there are no patents and non-patent literature reports on the use of lily polysaccharides as edible films at home and abroad.

Embodiment 1

[0013] The lily polysaccharide powder with a molecular weight of 320Kda is mixed with water into a viscous paste, heated and extruded at 80-90°C to form a film. The obtained lily polysaccharide edible film has better antibacterial properties and mildew reduction properties, and is acceptable in moisture resistance and toughness. It is suitable for food wrapping that does not require high moisture resistance and toughness, but has high requirements for antibacterial and mildew resistance.

Embodiment 2

[0015] The lily polysaccharide powder with a molecular weight of 430Kda is mixed with water into a viscous paste, heated and extruded at 80-90°C to form a film. The obtained lily polysaccharide edible film has good antibacterial properties, mildew reducing performance, moisture resistance and toughness. It is suitable for food wrapping that requires moisture-proof, toughness, antibacterial and mildew resistance.

Embodiment 3

[0017] The lily polysaccharide powder with a molecular weight of 530Kda is mixed with water into a viscous paste, heated and extruded at 80-90°C to form a film. The obtained lily polysaccharide edible film has good moisture resistance and toughness, and the performance of antibacterial and mildew reduction is acceptable. It is suitable for food wrapping that has high requirements on moisture resistance and toughness, but not high requirements on antibacterial and mildew resistance.

Abstract

The invention provides lily polysaccharide edible film which is prepared by heating, moulding and film forming of lily polysaccharide molecule with molecular weight of 301-500Kda and comprising glucose, galactose, mannose, arabinose and galacturonic acid. The obtained lily polysaccharide edible film has advantages of moisture resistance, antibacterial performance, reduced moldy and high toughness, and is good substitute of traditional edible moisture-proof film.

Description

technical field [0001] The invention relates to an edible film, in particular to an edible moisture-proof film of lily polysaccharide. Background technique [0002] Edible film is a film with a porous network structure formed by the interaction of different molecules with natural edible substances as raw materials. The earliest edible film was starch film made of starch. The earliest starch film used in packaging in my country, commonly known as glutinous rice paper, has been widely used in candy packaging in production, and candy can be eaten together. Edible films can be used in the inner packaging of various foods, such as liners for wrapping candies and sticky pastries, or made into casings, fruit coatings and capsules. At the same time, it caters to the trend of fast and convenient modern consumption, and has a huge market in the food industry. Such as adopting the instant noodle soup of edible film packaging, can be directly dissolved in water, no longer need to tear...
