GAS GENERATORS

Use of nitrogen gas for the preservation of food products

The food industry, beverages, and snack foods will focus on prolonging the shelf life of the product. by maintaining freshness and flavor for as long as possible In the past, food preservation methods were cooking, dried, vacuum-packed, exposure to radiation, or even preservatives. Although these methods will extend the shelf life of the food has increased. But it will not be able to maintain the taste, and freshness, which is an important feature of these types of products.

Nowadays, ways to maintain the quality and taste of food and beverage products are increasingly recognized and popular. Is the use of nitrogen gas to pack products in packaging, known as the ‘Environmental improvement process within the packaging’ (MAP Modified Atmosphere Packaging), or simply called Gas flushing, based on the principle of bringing nitrogen to replace oxygen. The oxygen in the air is considered an important factor that changes food products. The oxidation reaction, for example, causes oily food to smell rancid and change color or even spoilage due to the growth of microorganisms. These reactions can also affect the value of food, for example, the loss of vitamin C in fruit juices, including wine.

Therefore, the use of nitrogen, which is an inert gas that reacts with food more difficult than the oxygen in the package as a result, food products, beverages, or snacks made from natural ingredients do not change in appearance, color, and taste, as well as retain freshness for a longer time. In addition, it also maintains the value of nutrients from deterioration. And nitrogen can also increase the characteristics of beer-type drinks that will cause the beer foam to not collapse quickly. create satisfaction for the drinker as well.

In the food and beverage industry extending shelf life, and maintaining the taste and appearance of these products is value creation. and maintain the value of the product for a longer time, because extending the expiration (Shelf life) of the product, directly represents the cost and profit of the company.

Although nitrogen has such advantages. But the initial use of nitrogen in food packaging was not as popular as it should have been. Due to the high cost of nitrogen gas affecting the cost of products today, the evolution of technology is better. Buying gas from producers became unnecessary. Since there is a pure nitrogen gas generator in the market called Nitrogen Gas Generator, the cost per unit is reduced and worth the investment.

The operation of the nitrogen gas generator uses a principle known as pressure swing absorption, which is the application of high pressure to the carbon pellets contained within the machine. The pressure acts to push oxygen molecules into the charcoal pellet. while the oxygen is trapped The remaining nitrogen will be purer and purer, and the Nitrogen Gas Generator can set the time to adjust the value of nitrogen according to the level required by various industries.

The current leading manufacturer of nitrogen gas generators is Parker domnick hunter from England. Which is the inventor and distributor of pure nitrogen gas generators for the food and beverage industry for more than 29 years, has brought such products to be sold in Thailand through domnick hunter-RL (Thailand). Co., Ltd. In addition to being a global distributor of products for more than 20 years, also provides high-quality after-sales service. by checking equipment for customers every 6 months by skilled engineers and there is after-sales service for both spare parts. Fast maintenance within 48 hours, as well as providing consulting services and recommending nitrogen gas generators suitable for various food and beverage industries. To add value and prolong the shelf life of food and beverage products. which means lower costs and increased customer profits.
