Usage of Food use psa nitrogen generator

As a kind of fundamental environmental substances, nitrogen is a colorless and tasteless gas with inactive chemical property, which occupies 79% in earth's atmosphere. When gaseous nitrogen is used for preserving foods, there is no any chemical residue. It is a good and practical way to cover food for preservation by using nitrogen.

(1) Food package: Traditional vacuum package is rapidly replaced by nitrogen-filling package, which is applied in package of fired food, puffed food, bakery food, and fresh slices of various farm products, special cheese and fresh meet. Because nitrogen-filling package can more effectively maintain taste and nutrition of foods.

In addition, nitrogen-filling package can effectively protect the shape of food in package; prevent crumbly food from being crushed; avoid packed food adhesion together under pressure due to unbalance between interior and exterior pressures; avoid food packed food stiffening.


(2) Beverage Mixture: Oxygen dissolved in liquid and oil can cause precipitation. Oxygen existing in beverage can make the taste become bad and shorten its life. Gaseous nitrogen is conveyed in liquid during processing by applying a kind of method known as “mixture” (liquid is mixed by compressed air through sprayer). These nitrogen bubbles can remove oxygen in order to prevent non-carbonate beverages (fruit juice, tea and milk) and edible oils (peanut, olive, sunflower and rape oils) from being oxidized, deteriorated and faded.


(3) Nitrogen Expansion: For other foods, it is required to add gas for increase food volume. Nitrogen is used to puff edible oils, mayonnaise, margarine in barrel or peanut oil products for increasing their volumes and expansibility, so as to prolong their life.

When fruits and vegetables are kept in their optimum refrigerated storage temperature, their respiratory rates will decrease, and when applying nitrogen to make the oxygen level in storage equipment decrease to 2-5%, the respiratory rates of fruits can be further decreased.
