Food Grade Fermentation Bag

1. Product introduction

Food grade fermentation bag is a kind of packaging bag specially used for food fermentation, made of non-toxic and harmless materials, in line with national food safety standards. It has the characteristics of high barrier property, durability, environmental protection and convenience, which can effectively control the gas emissions in the fermentation process and ensure the quality and safety of food.

2. Characteristics of food-grade fermentation bags

High barrier property: Food grade fermentation bags are made of multi-layer composite materials with excellent barrier properties. It can effectively prevent the penetration of oxygen and water, and provide a stable fermentation environment for food. This high barrier not only guarantees the quality of the food, but also extends its shelf life.

Durability: Food-grade fermentation bags have good wear resistance and anti-aging properties and can be reused many times. This reduces production costs while also reducing environmental pollution. In addition, it also has good tensile strength and tear resistance, and can withstand a certain external force.

Environmental protection: Food grade fermentation bags are made of non-toxic and harmless materials, which meet the requirements of environmental protection. During use, it does not produce harmful substances and is harmless to the environment and human health. At the same time, because it can be reused, it also reduces the generation of waste.

Convenience: Food grade fermentation bags are simple to operate and easy to carry and store. It is suitable for large-scale industrial production, but also suitable for small-scale household use. The user only needs to put the food into a bag and seal it for fermentation.

Customized design: According to the needs of different customers, food-grade fermentation bags can be customized. For example, suitable materials and structures can be selected according to factors such as the type of food, fermentation time and temperature; It can also be designed according to the customer's brand and image requirements.

3. Application of food-grade fermentation bags

Food grade fermentation bags are widely used in the fermentation of various foods, such as dairy products, soybean products, vegetable products, etc. The following are some specific application scenarios:

Dairy fermentation: Fermentation is an important step in the processing of dairy products. The quality and taste of dairy products can be guaranteed by using food grade bags for fermentation. At the same time, due to its high barrier property, it can also extend the shelf life of dairy products.

Soy products fermentation: Soy products also need to be fermented during the production process. The use of food-grade fermented bags can ensure the hygiene and safety of soy products, while also improving their nutritional value and taste.

Vegetable products fermentation: vegetable products are susceptible to microbial contamination and oxidation deterioration during processing. The use of food-grade fermentation bags for fermentation can effectively avoid these problems and ensure the quality and safety of vegetable products.

Other food fermentation: In addition to the several common foods mentioned above, there are many other types of food that also need to be fermented. For example, meat products, aquatic products, etc., can be fermented using food-grade fermentation bags to improve their quality and taste.

4. FAQ

What is food grade fermentation bag?

Food grade fermentation bag is a bag specially used for food fermentation process, made of materials that meet food safety standards, and can provide a closed and suitable environment for food fermentation to ensure that the fermentation process is safe and does not pollute the food.

What are food grade fermentation bags made of?

Usually made of food-grade polyethylene (PE), polyethylene terephthalate (PET) and other materials, these materials are non-toxic, odorless, chemically stable, and do not release harmful substances into food.

Do food grade fermentation bags come in color? Does color affect fermentation?

Available in clear or white colors. In general, color has no direct effect on the fermentation itself, but transparent bags may be more convenient to observe changes in the fermentation process, such as color and bubble conditions.

How do food grade fermentation bags seal?

Common sealing methods are zipper sealing, heat sealing and so on. Zipper seal is easy to open and close, suitable for the need to check or add raw materials fermentation; Heat sealing provides a tighter seal and prevents air leakage.

Is there an exhaust design? Why do I need to exhaust?

Some food grade fermentation bags have an exhaust valve design. In the fermentation process, microorganisms will produce gases, such as carbon dioxide, etc., and exhaust can prevent the bag from bursting due to excessive expansion of gas accumulation, while maintaining the stability of the fermentation environment.

Does the exhaust valve prevent outside air from entering?

The high-quality exhaust valve has a one-way exhaust function, allowing the gas produced by fermentation to be discharged while preventing the entry of outside air to maintain the anaerobic or specific gas environment required for fermentation.
