During the holiday season, food takes centre stage. Meat, fish, desserts and prepared dishes travel long distances before reaching the table, and maintaining their freshness and flavour is a challenge that blends science, technology and sustainability.

At this time of year —when production and consumption rise sharply— ensuring food safety is just as important as enjoying a meal with family. This is where innovations such as deep freezing and modified atmosphere packaging (MAP) come into play, alongside on-site gas generation and high-efficiency cooling solutions developed by GasN2.

The Holidays: Higher Demand, Greater Preservation Needs

In December, food companies increase production to meet growing demand for fresh and processed products.

In this context, maintaining a consistent cold chain and controlling oxygen exposure are key to preventing oxidation, texture loss and microbial growth.

Proper food preservation not only ensures appearance and taste — it also helps reduce waste, protect consumer health and optimise energy use.

The Science Behind Effective Preservation

Most fresh products deteriorate due to oxygen and bacterial activity.

Through Modified Atmosphere Packaging (MAP), the air surrounding the product is replaced with a precisely formulated gas mix: nitrogen (N₂), oxygen (O₂) and carbon dioxide (CO₂).

Each gas has a specific function:

  • Nitrogen (N₂): prevents oxidation and maintains freshness without altering flavour.
  • Oxygen (O₂): helps preserve the natural colour of meat and fish.
  • CO₂: acts as a barrier against bacterial and mould growth.

The result is longer-lasting, safer and more sustainable preservation, allowing products to retain full quality even days after packaging.

Deep Freezing: Maximum Quality in Minimal Time

If modified atmospheres protect, deep freezing preserves.

Unlike conventional freezing, which can damage food texture, deep freezing lowers the temperature extremely rapidly, forming micro ice crystals that do not harm the cellular structure.

This maintains the product’s original texture, colour and nutritional value, even after long storage periods.

When combined with controlled atmospheres, deep freezing becomes an essential tool for ensuring food quality and safety, particularly during high-demand periods like Christmas.

GasN2’s industrial cooling solutions deliver precise thermal control, energy efficiency and adaptability across various processes — from refrigeration and storage to continuous deep freezing.

Innovation and Sustainability with GasN2 Solutions

GasN2 provides on-site gas generation systems —for nitrogen, oxygen or custom blends— and high-efficiency industrial cooling solutions that work together to optimise food preservation.

Key benefits include:

  • Continuous, autonomous supply of high-purity gases.
  • Energy savings and reduced operating costs.
  • Lower carbon footprint by eliminating transport and cylinder handling.
  • Enhanced safety and process control.

This enables food companies to ensure top product quality with minimal environmental impact, in line with the highest sustainability standards.

Preserving Food, Protecting the Planet

Efficient preservation doesn’t just improve food safety — it also supports a more sustainable production model.

Less waste, less transport and greater energy efficiency all contribute to a more responsible future.

This holiday season, as we enjoy familiar flavours, let’s remember that behind every well-preserved product lies technology that safeguards both our food and the planet.

GasN2 works year-round to ensure that innovation, efficiency and sustainability are always on the table.
