Knowledge about coffee packaging introduce how coffee deoxidizer is used

Candy and other "deoxidizer" it is also used to preserve coffee, do you know what it does? Today we will discuss food and oxygen scavengers for coffee.

About oxygen scavengers

A deoxidizer is a drug that puts the inside of a sealed container in a deoxidizing state. There are types of oxidation such as the use of iron, the adsorption of oxygen and the use of oxidation.

Benefits of using deoxidizer

By using deoxidizers to prevent oxidation, you can prevent the occurrence of molds and pests and prevent changes in fats and oils. It is widely used in food packaging.

The properties of coffee beans

When coffee beans are roasted, carbon dioxide gas is produced. At the same time, because it is in contact with air, it also begins the deterioration caused by oxidation. Have you noticed that the bags swell when they buy fresh coffee? This is due to the carbon dioxide produced by coffee beans.

The difference between valve and deoxidizer

Have you ever seen coffee beans sold in bags with valves? The valve discharges the carbon dioxide gas from the coffee beans to the outside, so that the external air will not enter the inside, preventing the airbag from expanding too much. If any, the valve is designed to remove the gas and cannot be said to completely prevent oxidation.

The difference between nitrogen filling and deoxidizer

The advantage of nitrogen filling of coffee for commercial coffee is the antioxidant effect of oil and aroma ingredients. In the case of coffee, it has the function of preventing the change of "aroma", so you can enjoy the aroma of fresh beans even after opening it. However, because it does not have the effect of inhibiting carbon dioxide, the bag may expand.

Advantages and disadvantages of deoxidizer specially used in coffee beans

Advantages

The deoxidizer designed for coffee beans absorbs the oxygen in the packaged container and the carbon dioxide produced by the coffee beans to prevent the coffee beans from deteriorating and maintain their quality. It can be said to be a drug that combines the benefits of coffee and nitrogen-filled packaging with each valve.

Shortcoming

In addition to carbon dioxide, carbon dioxide in coffee beans. As carbon dioxide continues to be absorbed by oxygen absorbers, coffee is in danger of losing its natural flavor because it contains a large number of aroma components. Be careful when the retention period becomes longer.

Let's use it! Deoxidizing agent

Oxygen inhalers are available in commercial stores, etc. For candy, coffee, etc., it is divided into different types according to the use, so please confirm before you buy. Sealing is important, so be sure to prepare a sealing machine. How to use it is very easy. Put the deoxidizer and coffee in a sealed bag and seal immediately with a sealing machine. Over time, oxygen and carbon dioxide are absorbed by oxygen absorbers and may be preserved for a long time.

Summary of scavengers for coffee

The deoxidizer used in coffee can protect coffee beans from oxidation and maintain quality. This is the recommended drug to keep coffee beans in good condition. However, since the aroma components of coffee are also absorbed with carbon dioxide, long-term preservation may damage the natural gas flavor and flavor of coffee beans.

In fact, scavengers are rare in coffee shops where black coffee is sold.

Drinking beans fresh is the best way to enjoy the original taste of coffee. Due to the use of oxygen scavengers, I feel uncomfortable and suggest using them as soon as possible.
