1. What is nitrogen gas? Is nitrogen gas toxic?

Nitrogen gas, also known as Nitrogen gas, is an inert, colorless, odorless and tasteless gas, nitrogen with a purity of at least 99%, producing many important compounds such as amino acids, nitric acid, ammonia and cyanides, have no adverse effect on the food or beverage with which it comes into contact. Thanks to these non-toxic features, nitrogen gas is applied in food packaging technology because it helps food to last longer and retain its freshness.

2. Application of nitrogen gas in life and coffee packaging

Food products spoil in different ways. Whether due to microbial growth, discoloration, oxidation or moisture loss. By absorbing all the moisture, replacing the oxygen in the packaging with pure gas or a mixture of gases that are nitrogen, the shelf life of the product can be greatly extended, keeping the product in good condition, The smell and taste lasts much longer than other methods. Therefore, nitrogen gas is a very important gas in the preservation of fresh and processed foods

Nitrogen gas is used a lot in our human life

Nitrogen can be used for packaging in the processing industry of many foods, including meat, poultry, seafood, fruits, vegetables, pasta, dairy products, baked goods and prepared meals. Ready-made to help food stay fresher for longer
Application of preserving roasted coffee from nitrogen gas:
Based on the inert nature and can replace oxygen gas, nitrogen gas is used to preserve roasted coffee beans. This technology is essentially to maintain the freshness of the coffee in the packaging from roasting to brewing. Because when freshly roasted coffee beans will be affected by oxygen and moisture. It is oxygen that causes the quality of coffee beans to decrease. The moisture will reduce the aroma and cause it to lose its taste.

In the case of packaging roasted coffee, it will take a suitable amount of time for the CO2 in the packaging to escape. If CO2 does not escape, when packing, the packaging will swell, ugly and occupy the area. At this time, people will use nitrogen gas for the purpose of vacuuming. The inside of the coffee bag contains nitrogen, which will keep the aroma and flavor for a long time in the sealed package.

3. Nitrogen generator in capsule coffee packaging (coffee capsules):

Nitrogen gas slows down rancidity and other types of damage caused by oxidation. Nitrogen is used to preserve the freshness of packaged and bulk foods.

Aro Bao Khanh Co., Ltd. has applied nitrogen generation technology to serve the packaging of Nespresso and Kcup capsule coffee to bring consumers excellent coffee quality. Fresh, pure taste
