Tocopherol food grade is a natural antioxidant commonly used to inhibit lipid oxidation in food. Apart from its applications in the food industry, tocopherol is also used in the cosmetic industry due to its properties. While all the types of tocopherols are beneficial, studies have shown that gamma vitamin e is the most beneficial when used cosmetically. Here are the types of tocopherol.
Vitamin E alpha tocopherol is a natural antioxidant that slows the rate of lipoperoxidation change in tissues, and erythrocytes and thus prolongs the storage life of raw and cooked food fats and foods rich in fats. It also exhibits antioxidant activity on food and enzymatic oxidation.
Alpha-tocopherol is primarily used in the food industry due to its ability to prevent oxidation in various food products. Considered the most potent form of vitamin E, this variant effectively extends the shelf life of oils, fats, and other perishable food items. Besides preventing rancidity, alpha-tocopherol enhances the nutritional value of food, adding to its appeal in both health and food sectors.
Beta-tocopherol has been found to possess weaker vitamin E activity than alpha tocopherol and gamma tocopherol because it cannot undergo GCE. Its sour smell and miscibility with water make it a poor candidate for incorporation into food-related products.
Beta-tocopherol is rarely found in food but has been identified in certain vegetables and grains, as well as in beeswax. Due to its properties, it has no applications in the food industry. However, its cosmetic applications include anti-acne products, high-performance and long-lasting moisturizers, and anti-sun products, among others.
Gamma-tocopherol is the most abundant vitamin E found in foods and is especially prominent in certain oils. While it has slightly lower vitamin E activity than alpha tocopherol, studies show it exhibits a variety of biological activities. These include anti-inflammatory properties and potential protection against certain diseases, such as cancer and cardiovascular disease. However, there is still a lack of consensus in the scientific community on this matter.
Tocopherol is highly useful when added to food products as it helps prevent lipid oxidation. It is also added as a dietary supplement. Some of the food sources that contain gamma-tocopherol include corn oil, soybean oil, canola oil, and many others. Its ability to extend the shelf life of foods, enhance nutritional value, and provide health benefits makes gamma tocopherol an excellent additive for food and supplements.
Delta-tocopherol is not as commonly found as other tocopherol forms but still holds potential as a food-grade antioxidant. It shares structural similarities with gamma-tocopherol and exhibits antioxidant activity that can protect against oxidative stress.
While it's often found in smaller quantities in food sources, delta-tocopherol is being explored for its potential health benefits, which may include anti-cancer properties.
When purchasing tocopherol for food purposes, buyers must understand several factors to make informed purchases. Below are the factors to consider when buying tocopherols.
When purchasing tocopherol food grade, buyers must ensure the product is of food grade purity and quality. Such products are usually manufactured in facilities adhering to GMP regulations, and it is常常 verified by independent third-party laboratories. Alpha-tocopherol should preferably be 98% pure or more and synthetic forms are preferable.
As mentioned earlier, gamma and delta tocopherols possess several healing properties. Therefore, gamma-tocopherol and the rest of the co-tocopherols should be in small amounts to enhance the antioxidant activities of alpha-tocopherol. When buying vitamin e for food grade supplements, buyers should focus on tocopherol blends that contain the aforementioned co-tocopherols.
Buyers should also ensure that the ingredients used to derive vitamin e are of high quality. For instance, organic oils used should be non-GMO and preferably sourced from organic soybeans or sunflower seeds. Also, other ingredients in the blends should be scrutinized to ensure the product is free from additives, fillers, or artificial ingredients. Furthermore, buyers should look for tocopherols that list their vitamin e content on the product label.
Smart buyers always request certificates of analysis so they can be sure the products purchased have passed the required quality tests. A reputable supplier places a premium on transparency and client happiness. They give COAs and refer to dubious industry practices to ensure the reported values correspond with the actual product statistics, just as they settle for nothing less than top-shelf merchandise.
When purchasing vitamin e, buyers should also consider its safety. For instance, check whether the product adheres to the newest standards for contaminants like heavy metals, pesticides, and solvents. In addition, other purity metrics like the product's country of origin or achievement certificates will reassure buyers of its safety for food and supplement usage.
Tocopherol is popular in several industries. While it has multiple applications in the food and cosmetic industries, its most popular use is as an antioxidant. Below are some of the applications of food grade tocopherol.
Tocopherol, as mentioned previously, is primarily used in the food industry to prolong the shelf life of food products by preventing oxidation. This is normally achieved by adding it to fatty foods like oils, nuts, and meats.
Vitamin E is often sold in dietary supplement form to provide its antioxidative benefits. Supplements containing tocopherol are used to promote overall health and prevent vitamin E deficiency. Additionally, taking these supplements in conjunction with other anti-oxidative supplements like astaxanthin enhances their effectiveness.
Tocopherol is commonly added to moisturizers, anti-aging creams, sunscreens, and other skincare products. Its antioxidative property helps in neutralizing harmful free radicals in the skin, which helps to prevent skin damage and premature aging. Furthermore, tocopherol is known to improve skin hydration by enhancing moisture retention and reducing dryness.
Tocopherol is used as an antioxidant in certain industrial applications, such as in the formulation of lubricants and oils. Just like food and cosmetic products, lubricants are prone to oxidation, and tocopherol helps extend their stability and lifespan. Its role in preventing oxidative degradation ensures longer-lasting and efficient lubricating products for machinery and equipment.
Vitamin E is usually extracted from sunflower oil and soy oil. Other oils that might be used include wheat germ oil, olive oil, and even palm oil. The extracted oil is then subjected to molecular distillation to separate and purify the different tocopherols. The pure tocopherol is then converted into tocopherol acetate through an acetic anhydride catalyzed rectification process.
Budapest released tocopherols are usually incorporated into recommended food dosage ranges of 30-300 mg per kg of food. It is worth mentioning that this vitamin is heat resistant and thus can be used in food manufacturing processes without destroying it. Besides its applications in food and supplement products, vitamin E is added to skin care products with oil bases.
Cosmetic vitamin e should be stored ideally at cool temperatures of about 20-30 degrees Celsius. Protect the product from direct sunlight and store it in opaque containers to avoid exposure to light, as this may degrade its quality. It's also important to seal the containers tightly to avoid air exposure, which can lead to oxidation. Vitamin E should especially be stored in a cool place if the product contains tocopherol acetate. This is because prolonged exposure to high temperatures can cause hydrolysis of the compound, converting it to tocopherol alcohol, which is less effective.
A1. While vitamin E refers to a group of compounds, alpha-tocopherol is just one member of that family. Alpha-tocopherol is the most potent form of vitamin E and is often highlighted in supplements and studies. However, other forms like gamma-tocopherol also possess unique benefits, such as antioxidative properties and anti-inflammatory functions.
A2. Although the majority of vitamin E supplements are derived from plant oils like soybeans and sunflowers, there are synthetic variants. Typically, naturally occurring vitamin E is usually derived from non-GMO soybeans or sunflower oil. However, there are also vegan forms of vitamin E derived from algae, which offer a similar profile of benefits like alpha, beta, gamma, and delta tocopherols.
A3.The recommended daily allowance of vitamin E typically depends on age and gender. For adults, the RDA is usually 15 mg per day, equivalent to 22 IU of alpha-tocopherol. However, this may not be applicable for naturally occurring vitamin E, where the IUs can go up to 1000. High doses should only be taken under medical supervision.
A4. High doses of vitamin E, especially over 1000 IUs a day, can cause nausea, diarrhea, and abdominal cramps. In rare cases, it may even cause bleeding and bruising because of its anticoagulant properties. Therefore, people taking vitamin E should do so in moderation and consult medical practitioners when taking high doses.
A5.Vitamin E is a potent antioxidant that helps neutralize free radicals, which are harmful byproducts of cellular metabolism. Free radicals cause oxidative stress, damaging cells and potentially leading to chronic diseases. By scavenging these free radicals, vitamin E may help reduce the risk of conditions like heart disease and cancer.
