Problems solved by technology

There are many kinds of edible packaging seen in daily life, and each edible film has its disadvantages. For example, the glutinous rice paper in the polysaccharide film is edible, but its strength is poor, and it is easy to get wet when exposed to water. It is damaged and the production scale is small, so it is difficult to meet the needs of food packaging; another example is the edible casing processed from the animal small intestine in the protein film. Although the performance is good, it cannot be used in large-scale food because of its high cost Package

Embodiment 1

[0017] In terms of mass percentage, 2% inulin, 0.5% sodium alginate, and 3% plasticizer glycerin are fully dissolved in water, and the mixed solution is placed in a 60°C constant temperature water bath and heated and stirred until it becomes a lump-free glue liquid. After stirring, stand at room temperature for 12-24h for degassing treatment; the degassed solution is poured on a glass plate to ensure the thickness of the film. Put the glass plate with the film poured into a 60°C constant temperature blast drying oven to dry. The dried glass plate with film is immersed in 5% calcium chloride cross-linking agent for crosslinking for 1-5min, and then placed in an oven at 40-60°C for drying. After drying, place the filmed glass plate in saturated nitric acid Soften in the desiccator of the magnesium solution for 24-36 hours, and finally peel off the film to obtain the edible inulin composite packaging film. The film-forming properties are shown in Table 1.

Abstract

The present invention relates to food fresh keeping, and specifically to an edible inulin composite packaging film, a preparation method and an application thereof. The edible inulin composite packaging film is formed by compounding a film forming base material, an auxiliary film-forming agent, a plasticizer and a cross-linking agent, wherein the film forming base material is inulin, the assistant film forming agent comprises sodium alginate and water, and the raw materials comprise, by mass, 2-50% of inulin, 0.25-2.5% of sodium alginate, 1-5% of a plasticizer, 1-5% of a cross-linking agent, and the balance of water. The edible inulin composite packaging film of the present invention has characteristics of high transparency, good edibility, good antioxidant property, and the like. The film forming base material inulin is a soluble dietary fiber, provides physiological health functions for human body, and can provide a certain nutrients for microbes inside human body. The film preparation process of the present invention has characteristics of simple process, low cost, fast film forming curing, wide raw material sources, good taste of the formed film, and environment protection. In addition, the edible inulin composite packaging film can be adopted as meat product fresh keeping films, fruit and vegetable fresh keeping films, candy packaging films, medical equipment materials or can be applicable for preparations of disposable daily necessities.

Description

technical field [0001] The invention relates to food preservation, in particular to an edible inulin composite packaging film and its preparation and application. Background technique [0002] Edible film refers to a film made of edible materials, which mainly ensures the quality of food and prolongs the shelf life of food by preventing the migration of gas, water vapor and solute. There are many kinds of edible packaging seen in daily life, and each edible film has its shortcomings. For example, the glutinous rice paper in the polysaccharide film is edible, but its strength is poor, and it is easy to get wet when exposed to water. It is damaged and the production scale is small, so it is difficult to meet the needs of food packaging; another example is the edible casing processed from the animal small intestine in the protein film. Although the performance is good, it cannot be used in large-scale food because of its high cost. Package. Contents of the invention [0003...
