Plastic waste is difficult to handle due to the fact that it is extremely difficult for foods to be naturally degraded by plastics. In order to solve such problems, some developed countries have adopted a series of measures, including partially restricting the use of plastic packaging. The development and application of edible wrapping paper is one of the effective ways to reduce waste and protect the environment.
The United Kingdom recently introduced a package of edible vegetables. This package uses carrots as a base material, thickeners, plasticizers, water repellents, and carrots to produce natural, inexpensive, edible colored vegetable paper. Such products can be used as individual packages of boxed foods or directly consumed as convenience foods, which can not only reduce environmental pollution, but also enhance the beauty of foods and increase the appetite of consumers for food and fun.
Carrot paper is an edible color paper that has strong flexibility and a certain degree of waterproofness, and has a packaging function and a food function. If we can further improve the strength and plasticity, improve the texture of the surface, and make products of various shapes, we can further expand its use, better protect the environment, and provide new ways for deep processing of vegetables.
The product's production process is simple and practical, with great market potential. The fully dissolved and expanded sodium alginate solution and the blanched carrot mass were placed in a beater and broken into a homogenous paste. Glycerol was added to the mixture and stirred in a vacuum oven for degassing. The degassed edema fluid was poured into a homemade stainless steel mold for forming. After forming, it is placed in an electric oven and dried. The temperature is controlled between 60 degrees and 65 degrees. After the carrot pulp is dried into a sheet, it can be peeled off. After removing it, it is coated with a self-contained water repellent and placed in an oven. , Sealed after cooling.
