What Is Antioxidant
Antioxidants are indispensable chemical compounds often functioning behind the scenes, typically to safeguard the quality and integrity of various industrial products. These remarkable agents are akin to silent protectors, tirelessly preventing the detrimental effects of oxidation on a wide range of materials. These compounds are versatile by nature and play a prominent role in ensuring operational efficiency. A crucial element that combats oxidation, the role of these antioxidants goes beyond that. Foods are also treated with antioxidants to forestall spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol, or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress.
Advantages of Antioxidant
They better support food production processes and protect the final product more
Due to the composition and chemical characteristics of natural antioxidants, they are less volatile and more stable at high temperatures, which means that they better support food production processes such as frying, cooking or baking, making them more effective in the protection of the final product. This property of “surviving” the thermal process and remaining in the final product is known as “Carry Through”.
They are usually more soluble than synthetics
Another benefit of natural antioxidants is that they are often more soluble than synthetics. Because an antioxidant cannot reverse the autoxidation process, but only prevent it, it is important to ensure that its distribution in the lipid medium is as homogeneous as possible.
There are soluble in oil and soluble in water
On the other hand, there are natural antioxidants that are soluble in oil and soluble in water, so depending on the production process and the product to which they will be added, there are different solutions. In addition, in the market it is easy to find prepared solutions with components which, for example, make it possible to convert a liposoluble antioxidant into a water-dispersible ingredient.
They have no effect on the colour, taste or odour of the final product
It is worth noting that there are natural antioxidants such as Tocopherols or Ascorbic Acid, and due to the low doses in which they are used, they have no effect on the colour, taste or odour of the final product.

Types of Antioxidant
Synthetic antioxidants
Synthetic antioxidants are of potential use in chemistry, the food industry and medicine. Some of these compounds retain functional group chemistry analogous to that of “natural” antioxidants and introduce new chemical groups that enhance their range of cellular action or make them available to cell sites hitherto restricted. Alternatively, some synthetic antioxidants bear no structural analogy with natural antioxidants and exhibit a high reactivity toward reactive oxygen species and display selective protection in certain tissues. A large number of synthetic antioxidants are available for the stabilisation of nonfood materials such as plastics, rubber and polymers. However, the use of synthetic antioxidants in foods requires that different aspects be taken into consideration including technological necessity, the toxicology of lipid oxidation products and the toxicology of antioxidants.
Natural antioxidants
Plants are persistently the generous source to supply man with valuable bioactive substances and thus different plant products are being evaluated as natural antioxidants to improve the overall quality of meat and meat products. The focus on using natural antioxidants for the effective preservation of meat or meat products has almost exclusively been on the use of plant phenolics or phenolic-containing extracts. Phenolic compounds are plant secondary metabolites commonly found in herbs and fruits, vegetables, grains and cereals, tea, coffee and red and white wines. Phenolic acids are phenols that possess carboxylic acid functionality. Phenolic compounds can be broadly divided into two categories. Among phenolic compounds found in plants, flavonoids are the most widely studied class of polyphenols with respect to their antioxidant and biological activities.
Where Can Natural Antioxidants Be Used Within the Food Industry
Ascorbic Acid (E-300)
Ascorbic Acid (E-300), along with its derivatives, is one of the antioxidants used in foods such as meats, juices, beverages, pastries or fruits. In baking it can also be used as a technological aid that helps to improve dough. Its application in fatty products is limited due to its lipid insolubility. This additive acts as an antioxidant through the extinction of oxygen, the reduction of free radicals and the regeneration of primary antioxidants. It is considered a safe food additive and has no use limits. Ascorbic Acid is very susceptible to elements such as heat, light or oxygen, so it is often necessary to add it exogenously to food. vIn addition to its antioxidant activity, it acts as vitamin C, a flavouring, acidulant, colour fixative and reducing agent.
Tocopherols (E-306)
Mixtures of Tocopherols (E-306) are another natural antioxidant most used in food, mainly in products containing fats, such as oils, cookies, cereals, snacks, sauces, flour, confectionery, etc. Tocopherols are a mixture of four isomers and their antioxidant activity lies mainly in the Gamma and Delta isomers, being practically null in the Alpha and Beta isomers. These antioxidants prevent the oxidation of fats by stopping chain reactions of free radicals. Why choose natural antioxidants based on tocopherols? Antioxidants based on Tocopherols are an excellent solution to stabilise fats and oils. They are a natural antioxidant with a lot of benefits, such as its resistance to high temperatures, its high solubility, its null impact on the colour or odour of the final product, or the possibility of being used in organic products. In addition, it is allowed to use as an antioxidant in any country in the world.
Rosemary extract (E-392)
Rosemary extract (E-392) is another antioxidant widely used in food. It has a good performance in animal fats, but has certain problems of smell and taste. It is often used in combination with other antioxidants such as Tocopherols looking for a synergistic effect between these ingredients. This antioxidant is an extract obtained from the Rosemary plant using solvents suitable for human consumption. Its most important compounds from the antioxidant point of view are Rosmarinic Acid, Camosol and Carnosidic Acid.
Preservation of product quality in food and cosmetics
Across diverse industries, maintaining product quality is of utmost importance. Antioxidants significantly help preserve the product quality regardless of the application and industry. In the food industry, for instance, antioxidants like antioxidant 1010 are used to extend the shelf life of food products. By delaying lipid oxidation, the antioxidants prevent the development of rancidity and off-flavour, ensuring that the product is of high quality, fresh and in food condition. Similarly, in the cosmetics industry, antioxidants guard against active ingredient degradation and product texture and colour deterioration. The ability to preserve the product quality helps keep the effectiveness and aesthetics of the cosmetic products alive.
Enhanced stability of pharmaceutical products
Considering how stability is vital in the pharmaceutical industry, antioxidants play a critical role in determining the safety and efficacy of the products. The antioxidants step in as stabilizing agents in medications, vaccines and healthcare products, particularly hindered phenolic antioxidants like antioxidant 1076. These antioxidants protect pharmaceutical products from oxidative degradation caused by factors like exposure to light, heat, and oxygen. By maintaining stability, the use of antioxidants ensures that the medications retain therapeutic properties, a viral aspect of patient care products.
Longevity of polymer products
Polymers, accessible and available in various forms like plastics and rubber, are particularly vulnerable to oxidation-induced degradation. Antioxidants, typically like antioxidant 168 and antioxidant 1098, are instrumental in extending the lifespan of polymer products. In the automotive industry, for instance, where rubber components must withstand harsh environmental conditions, antioxidants safeguard against premature ageing and deterioration. By neutralizing free radicals and delaying oxidation reactions, the antioxidants ensure the longevity and reliability of the vital components.
Fuel quality assurance
The fuel industry relies on antioxidants to maintain fuel quality, a factor critical for engine performance and operational efficiency. Antioxidants combat the formation of gum and varnish deposits in engines and fuel systems, a phenomenon that can delay fuel flow and reduce engine efficiency. By preventing these deposits, antioxidants ensure that the fuels burn cleanly and efficiently, leading to improved engine performance, reduced maintenance costs, and lower emissions.
Protection in paints and coatings
In the industries where paints and coatings are used, antioxidants play a prominent role in preserving the colour vibrancy and durability. These antioxidants shield painted surfaces from the ravages of oxidation, which can lead to fading, peelings, and reduced protection against corrosion. Antioxidants like antioxidants 1010 play a critical role in preserving the aesthetics and functionality of painted structures, be it architectural coatings or industrial coatings on machinery and equipment.
Textile industry guardian
The textile industry is yet another beneficiary of antioxidants. Fabrics, fibres, and textiles are exposed to a range of environmental factors causing degradation. Antioxidants are introduced to protect these materials from the harmful effects of uv radiation, heat and humidity. By extending the life of textiles, antioxidants contribute to sustainability by reducing the need for frequent replacements and lowering the environmental footprint of the industry.
The increasing consumer awareness regarding the use of natural antioxidants has led to exploring new natural sources of these compounds. As such, by-products obtained from the agri-food industry constitute an important source of natural antioxidants.
Prior to commercialization at the industrial level, it is first necessary to extract the antioxidants using, if possible, green extraction methods. Secondly, the antioxidant obtained must be characterized considering that their biological activity differs if they are alone or in a matrix. For this purpose, both screening (e.g., spectrophotometric techniques) as well as advanced analysis techniques, including the use of liquid or gas chromatography, coupled with mass detectors, triple quadrupole, etc., will be necessary.
Once the compounds are characterized in a global or individualized way, studies will be necessary to demonstrate their safety, for example, cytotoxicity studies. In vitro and in vivo bioavailability and bioavailability tests will also be required considering the application, since these may be included in active packaging or in food, as food additives, or for different purposes.
