The mechanism of action of the respective systems are also explained adequately.Many naturally occurring oxygen scavengers based on phenolic compounds and naturally occurring minerals like hydrotalcite have been mentioned in this review which have not yet been investigated thoroughly. Oxygen Scavengers - Frequently Asked Questions As a means of addressing concerns about using hydrazine as an oxygen scavenger and to compare several competing products, Arch Chemicals, Inc., has prepared the following questions and answers to aid in your decision making about oxygen scavengers.

In this review, oxygen scavenging systems like iron, palladium, ascorbic acid, tocopherol, unsaturated hydrocarbons, microorganisms have been thoroughly discussed along with their applicability with respect to the moisture content of the targeted food products. TEMPO has a wide range of applications including use as a free radical scavenger, a reagent in organic synthesis and as a structural probe in electron spin resonance spectroscopy.

Oxygen scavengers are a type of active packaging technique which absorb the dissolved oxygen or oxygen in the headspace leading to extended shelf life and retainment of the original food quality.Extensive work has been done in this particular field. They protect food products against oxygen degradation, thus increasing the shelf life, customer acceptability, and safety of food products. One of the main causes of food and beverage deterioration is the presence of oxygen inside the package of sensitive foods. Typically, organic oxygen scavengers are carbon based comprising compounds using carbon. What are the two primary types of oxygen scavengers As a rule, generally oxygen scavengers are divided into organic and inorganic types. Addition of oxygen scavengers is one of the means to reduce the oxygen exposure on food products. Oxygen scavengers are used to extend the shelf life and maintain the natural efficacy of food products. 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. Oxygen scavengers are a concoction of natural compounds designed to react with oxygen in order to eliminate it (oxygen). Additional oxygen may be dissolved during agitation at surface. The use of oxygen scavengers is more critical in applications in which fluids are to be circulated in the wellbore. Many food products available are sensitive to oxygen and which upon prolonged exposure may lead to deterioration in the food quality like change in taste, odour and colour of the food or facilitate the growth of microorganisms in them. Oxygen scavengers capture the dissolved oxygen in a harmless chemical reaction that renders the oxygen unavailable for corrosive reactions.
