Necessity of nitrogen in Food Packaging Field
Because nitrogen is inert at room temperature and is not easy to breed bacteria, it is widely used in the preservation and storage of beverages, fruits, vegetables, cakes, tea, Chinese herbal medicine, pasta and other foods. It can fully maintain the original color, aroma and taste. The storage quality is obviously better than mechanical refrigeration.
1. Food packaging
Nitrogen-filled packaging is rapidly replacing traditional vacuum packaging and is used in the packaging of fried food, puffed food, baked food, freshly sliced agricultural products, special cheese and fresh meat. Nitrogen-filled packaging can better maintain the taste and taste of food. and nutrition, and its application fields are expected to further develop.
The deterioration of food is mostly caused by oxidation reaction under the participation of O2, and promotes the reproduction of microorganisms and bacteria, resulting in food spoilage. As a suffocating inert gas, N2 has suffocating and inhibiting effects on bacterial reproduction in food. The purpose of using N2 is to eliminate O2, slow down the oxidation and respiration of food, and the solubility of N2 in water and oil is small. The adsorption effect of food on N2 is relatively small, so it can be used as a better gas for food preservation and preservation.
In addition, nitrogen-filled packaging can also play a good role in protecting the shape of the food inside; prevent crispy and fragile food from being crushed; avoid the unbalanced internal and external pressures that cause the packaged food to be bonded together under pressure to make its texture Hardening; even food with irregular shape can keep the appearance of the package body, and reduce the deterioration of the food due to the damage of the packaging material caused by surface folds.
2. Drink stirring
Oxygen dissolved in liquids and oils can cause them to precipitate, and the oxygen in these liquids can make them worse and shorten their lifespan. Using a method known as "churning" (compressed gas through a nebulizer to agitate the liquid), gaseous nitrogen is passed through the liquid during the treatment process. These nitrogen bubbles remove oxygen to prevent carbonated beverages (juice, tea and milk). ) and edible oils (peanut, olive, sunflower and canola) oxidation, spoilage and discoloration.
3. Nitrogen puffing
Other types of food require the addition of gas to increase their volume. Using nitrogen to "fluff" food oil, mayonnaise, barrel margarine or peanut oil products can increase their bulk and swelling power, thereby extending their life.
1. Used before beer, wine, fruit wine, edible oil, pressure canning, bottle blowing, and capping, it can remove oxygen to prevent oxidation, corruption and fading of non-carbonated beverages and edible oils. If a cork stopper is used, it can prevent mildew in the cork.
2. Puffed and fried food: It can prevent the food from being soft and tasteless with a small amount of water, and the appearance and packaging are good-looking, and it is not easy to be crushed during transportation.
3. Cakes, baked goods, egg yolk pie: After nitrogen filling, it can prolong the preservation time and prevent deformation and crushing during transportation.
4. Milk powder and soybean milk powder: Using a small amount of nitrogen can prevent or reduce the agglomeration caused by long-term extrusion and storage of milk powder.
5. Cereals, nuts, fruits, vegetables: Filling with nitrogen can prevent the harm of pests, and leaving trace oxygen can also reduce the respiration rate of fruits, and the preservation effect is obvious.
6. Candy and small food: mainly suitable for packaging in airtight bags.
