The most used O 2 scavengers are based on the principle of iron oxidation. Often the oxygen absorber or scavenger is enclosed in a porous sachet.

A Concise Guide To Active Agents For Active Food Packaging Sciencedirect

However the oxygen that permeates from the outside environment into the package through the packaging material cannot be removed by this method.

Oxygen scavengers food packaging. It should comply with the current regulation on food contact. More specifically oxygen scavengers refers to a category within active packaging. When the pigment for red meat myoglobin is exposed to oxygen the meat appears as a bright red color which is associated with freshness and overall acceptability.

However when meat is exposed to too. Vacuum packaging of food is the most common method of food packing to prevent oxygen seeping in from the environment. Sachets plastic films labels plastic trays and bottle crowns.

Oxy-Guard oxygen scavengers are available globally in a variety of sizes. Oxygen accumulates in the packaging and that is the main reason for food degradation. Oxygen scavengers or oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package.

Pires year2012 Oxygen O2 presence in food packages is mainly due to failures in the packaging process such as mixture of gases containing oxygen. Other oxygen also reacts with other gases and creates residual gases. They are used to help maintain product safety and extend shelf life.

Oxygen scavengers are used in food packaging to protect oxygen-sensitive food products. Development of smart packaging solutions for oxygen scavengers. Contrast yeast ascorbic acid ie vitamin C enzyme and photosensitive dye were often used as organic oxy- gen scavengers in the literatures3437 In which iron powder and ascorbic acid are the most often used oxygen scavengers in the food packaging.

One of the main causes of food and beverage deterioration is the presence of oxygen inside the package of sensitive foods. Active agents can work through direct contact with foods or by generating a vapor phase that transfers the antioxidant activity to the headspace. Clariants Oxy-Guard oxygen scavengers can be used to preserve baked goods nuts dried grains pasta processed and dried meats coffee and tea chocolates and confectionary dairy products powdered proteins and beverages frozen meals and pet foods among other products.

Oxygen scavengers can be physically adsorbed or coated onto food packaging materials so that the scavenger migrates from the package to the food to prevent oxidative reactions in the food products Fig. This in turn protects the product from degradative oxidation reactions. An Approach on Food Preservation authorR.

Oxygen scavengers are packaging films or devices that chemically react with oxygen to remove it from the packaging environment. Food degradation also occurs due to inefficient vacuum. Oxygen scavengers packets are absorbed approximately three times of its weight in scavengers and protect products from the mold mildew oxygen moisture loss of quality test and color change.

Modified atmosphere packaging MAP is often used as an alternative to reduce the O2 inside food packaging. Oxygen scavengers OS represent an innovative and effective solution applied to food packaging in order to extend the shelf life of sensitive and perishable foods subjected to oxidative degradation. Several studies have reported the application of oxygen scavengers to food packaging and its effects on food quality attributes.

O2Block additive is primarily designed to maximize shelf life for diverse packaging made of materials such as LDPE and HDPE PP PET and polylactic acid PLA for the food and pharmaceutical industries. The technology uses purified and modified layered clay as a performance-enhancing carrier of the oxygen-scavenging iron. Application on transparent plastic will be valued.

There are many types of oxygen absorbers available to cover a wide array of applications. Oxygen scavengers are one of the most widely used active packaging technologies. The use of oxygen scavenging packaging materials means that oxygen dissolved in the food or present initially in the headspace can potentially be reduced to levels much lower than those achievable by modified atmosphere packaging Zerdin et al 2003.

These oxygen scavenging system are used in various forms such as. The most commonly used enzymes for oxygen scavenging in food packaging are glucose oxidase GOx along with catalase Cat Strobel Gagnon 1998 Johansson Joensson Jaernstroem 2011. The scavenging takes place by the following mechanism where glucose must be present in food or in the scavenger formulation.

A variety of oxygen scavengers have been commercialised for use in the food packaging industry. Oxygen Scavenger Packets - For hdpe bottle packaging. Oxygen scavengers are used in meat packaging to con-trol color in red meat packages.

Vacuum packaging has been widely used to eliminate oxygen in the package prior to sealing. Oxygen capture 03 Easy implementation in packaging chain. In this article We describe about Oxygen Scavengers for Food Preservation.

A mixture of gallic acid GA and sodium carbonate was used as an oxygen scavenger OSc in bio-based. In this context research and developments in the food packaging area have been conducted. Solutions not of interest.

The components of an oxygen absorber vary according to intended use the water activity of the product being preserved and other factors. The use of OSs was implemented through selfadhesive labels other adhesive devices loose sachets to be included in the packaging with the food or the utilization of active elements in the monolayer or multilayer packaging material for bottles and jars 456.
