Abstract

The invention provides a preparation method for a banana skin drying agent and a drying mould-proof bag containing the banana skin drying agent. The preparation method comprises the following steps: cleaning and cutting the banana skin; soaking the cut banana skin into acetic acid-ethanol solution for activating; freeze-drying, crushing and screening the banana skin after being activated, thereby acquiring the banana skin drying agent. The drying mould-proof bag comprises a drying mould-proof bag body made from a breathable material, wherein the bag body is filled with the banana skin drying agent acquired according to the preparation method. The banana skin drying agent provided by the invention is natural and safe; the moisture adsorption effect is excellent; the wastes are turned into wealth; the additional value of the banana industry is increased; the banana skin drying agent is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of desiccants, and in particular relates to a preparation method of a banana peel desiccant and a dry anti-mold bag containing the banana peel desiccant. Background technique [0002] There are many types of desiccants, such as: quicklime desiccant, calcium chloride desiccant, silica gel desiccant and so on. Quicklime desiccants, calcium chloride desiccants, and silica gel desiccants are widely used because of their good drying effect and low price. However, in recent years, there have been many incidents of eye injuries caused by the explosion of the above-mentioned desiccants. It is not uncommon to see desiccant, which has attracted widespread attention; and the existing desiccant still has or uses chemical components, which have certain toxicity. Once the outer packaging leaks, it is easy to contaminate food and other substances that need to be preserved, or the preparation method complex deficiencies. ...
