Bag for packaging fermented food

Abstract

The present invention relates to a bag for packaging a fermented food. The bag comprises: a packaging material, wherein a fermented food product is stored in the packaging material, and a gas discharge hole is formed on one side of the packaging material; and a membrane filter installed at the part forming the gas discharge hole and used for filtering carbonic acid gas generated from the fermentedfood and blocking a liquid while passing the gas. According to one embodiment of the present invention, the gas discharge hole is formed in one side of the packaging material for storing the fermented food such as pickles, soy sauce, red peppers, pickled seafood and the like, and the membrane filter is mounted on the inner surface, forming the gas discharge hole, of the packaging material, so that only the carbonic acid gas generated from the fermented food can be smoothly discharged to the outside of the packaging material while the contents or the odors of the fermented food cannot be discharged so as to prevent the deformation of the packaging material due to the carbonic acid gas.

Description

technical field [0001] The present invention relates to a fermented food packaging bag, and more particularly, to a fermented food packaging bag that stores fermented food such as kimchi and can smoothly discharge carbon dioxide gas generated from the fermented food to the outside. Background technique [0002] Typically, fermented foods such as kimchi, soybean paste, red pepper paste, and salted fish are continuously fermented in foods stored and distributed in storage devices such as PET containers or retort bags during packaging and distribution. [0003] In this case, due to the decomposition of organic compounds, carbon dioxide gas is generated in the fermented food, which not only changes the taste of the fermented food, but also increases the pressure inside the storage device, causing the storage device to swell, or in severe cases , damage the storage device. There are problems that lead to product quality. [0004] Therefore, to solve the above-mentioned problems...

AI Technical Summary

Problems solved by technology

[0005] However, since chemicals such as antifoaming agents and gas adsorbents are stored in storage devices while being directly exposed to fermented foods, when the product is opened, the antifoaming agents or gas adsorbents are visually exposed to impair aesthetics

There is a problem of reducing consumer demand by making the product uneven

[0006] In addition, in the case of defoamers or gas adsorbents, there is a possibility that the chemical substances inside the packaging paper leak out due to external impact or poor packaging, which leads to a cost loss of the product

[0007] When a gas discharge device in the form of a check valve is formed in a storage device, there is a problem of lowering productivity and increasing manufacturing cost due to increased manufacturing processes
