Problems solved by technology

[0007] The technical problem mainly solved by the present invention is that the existing plasticine often shrinks due to the evaporation of surface water, even cracks, becomes dry, and hardens, and cannot be stored for a long time and is repeatedly used. The plasticine contains heavy metals and non-toxic substances. Natural volatile chemical components are not conducive to long-term contact and use of children. After children eat by mistake, they will cause harm to their bodies. A preparation method of high-viscosity and water-retaining edible plasticine is provided.

Abstract

The invention discloses a preparation method for a high-viscoelasticity and water-retaining edible plasticine, belonging to the technical field of preparation of plasticine. According to the invention, the carboxyl group on the molecular chain of bamboo charcoal viscose fiber prepared by using the method provided by the invention can generate a strong ion cross-linking effect with the amino groupon chitosan, so the viscoelasticity of the plasticine can be improved; materials used in the preparation method provided by the invention are edible substances; due to the hydrogen bond effect betweenthe hydroxyl group of the chitosan and the hydroxyl groups of cellulose and agar, or the interaction between the amino group and the hydroxyl group of the chitosan, the bamboo charcoal viscose fiberhas the porous characteristic of bamboo charcoal and facilitates dyeing of the plasticine; through the synergistic effect of the bamboo charcoal viscose fiber with water-absorbing raw materials like the chitosan, water-retaining and water-absorbing properties of the plasticine are improved; the agar used in the preparation method provided by the invention is in an amorphous state at a normal temperature and exerts an effect of increasing viscosity; the plasticine can be rapidly dissolved in water to form powdery polysaccharide substances, especially starch polysaccharide substances which can be decomposed into monosaccharides by salivary amylase and digested by children, and no serious physiological damage is caused to the children; thus, the high-viscoelasticity and water-retaining edibleplasticine provided by the invention has broad application prospects.

Description

technical field [0001] The invention discloses a method for preparing edible plasticine with high viscoelasticity and water retention, and belongs to the technical field of plasticine preparation. Background technique [0002] Plasticine, since it came out in 1956, plasticine has become children's favorite toy. The original playdough was only gray and white, but over the years it has come in a variety of colors and scents. Including glow-in-the-dark, gold, silver, shampoo, shave, and more. In addition, in the history of animation development, there have been many classic animations that used plasticine as a material and made animations through stop-motion animation technology. [0003] Today, the material and process of plasticine have undergone great changes. Unlike before, it cannot be mixed in color, cannot be reused, and is rough and hard. Now the upgraded version of plasticine is called "colored clay", no matter how high-end it is. It is called "ultra-light clay" and...
