Every extra day of shelf life in a fresh food means fewer losses in the industry, greater logistical reach and fewer returns in retail. For those who produce, package and distribute meat, dairy, fruit, vegetables and ready meals, shelf life is now a margin and competitiveness variable as well as a technical characteristic.<\/div>\n

\u00a0<\/p>\n

Active packaging has emerged as one of the answers to this challenge. In this guide, you will learn what reduces the shelf life of fresh foods, what active packaging is, which technologies exist and which criteria should guide your company\u2019s decision.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

A food\u2019s durability depends on several factors acting at the same time. Understanding each one is the first step in choosing the right strategy.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Bacteria, molds and yeasts are among the main causes of spoilage. In foods with high water activity, such as meat, dairy and leafy vegetables, microbial multiplication can compromise safety, appearance, odor and flavor within a few days. To go deeper into the logic of microbial control in industry, read the article on industrial microbiological control<\/a>.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The oxygen present in the package favors fat oxidation, loss of color and browning of fruits and vegetables. In plant products, the ethylene released by the food itself accelerates ripening and senescence.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Passive packaging only protects and contains the product. Active packaging acts on internal conditions, for example by absorbing oxygen or reducing microbial growth. Intelligent packaging monitors and informs, through indicators of temperature, freshness or integrity. In many projects, the three approaches are combined.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

In this case, the protection is incorporated into the packaging material to reduce microbial growth on the surface in contact with the product or with the internal environment. The approach is based on the same principles explained in the content on technology applied to plastics<\/a>.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
