What is Potassium Metaphosphate Potassium metaphosphate, also called potassium polymetaphosphate or potassium polyphosphate, is a compound of several phosphates and appears as colorless and odorless crystals or powder. It is derived from monopotassium phosphate and could slowly dissolve in water. In food industry, it often used as fatter emulsifier, humectant, sequestrant, texturizer, thickener and texture modifier mainly in seafood flavors. Food Application of Potassium Metaphosphate It is a gluten free additive that adds sour taste to processed food. It could stabilize, thicken and regulate the acidity and moisture in foods, therefore it often used in soft and alcoholic drinks, fresh and canned meats, process meats like sausages and ham, dried vegetables, chewing gum, chocolate products, cereals, candies, dairy products and baked goods. Basically, potassium could be find in almost all food, especially in meat products. Side Effect of Potassium Metaphosphate In general, potassium metaphosphate is safe for most people within approriate amount. However, it could be absorbed by the body quicker than those naturally found in foods, therefore, people with kidney disease who need to control the phosphate level might want to be more careful and get doctor’s suggestion before choosing the food or supplements containing potassium metaphosphate. What worth people’s attention is that too much phosphorus intake could increase the probabilities of heart disease and morality, even in people who have normal kidney function.

Potassium sorbate is a white salt that primarily used as a food preservative with E number 202. Its chemical formula of E202 food additive is CH3CH=CH−CH=CH−CO2K and can easily dissolve in water and alcohol. Preservative E202 can inhibit the activity of dehydrogenase in mold cells, and combine with sulfhydryl base in enzyme system, thus destroy many important enzyme systems and achieve the purpose of preservation and bacteriostatic action. Uses of E202 Potassium Sorbate Potassium sorbate in foods can inhibit molds and yeasts, as well as used as non nutritional sweeteners to meet the special needs of certain patients. It has a wide range of uses in food, beverages, pickles, tobacco, pharmaceuticals, cosmetics, agricultural products, feed and other industries. Because of its preservative, safety, stability and the improvement of the sensory properties of food, potassium sorbate is a kind of food preservative widely used in developed countries. Potassium sorbate can extend the retention period if added to wine beverages, soda beverages, fresh orange juice and other beverages in proper proportions. This preservative can be directly added to flour or pasta. It is dissolved in water or milk before adding to flour or dough. It would be better to use a small amount of vinegar to make the material acidified in advance when sorbic acid and potassium salt are used in starch products. Sorbic acid and potassium salt can be used in hard cheese, cheese powder, salted cheese, fresh cheese, emulsified cheese, prepackaged cheese and other food as preservative. There are three ways to use preservative E202: potassium sorbate is added to the salt solution and cheese is made from this salt solution; soak or spray the potassium sorbate solution before the cheese is sold; soak or sprinkle cheese with a sorbic acid solution containing a certain amount of alcohol. Besides, it is used in many personal-care products, and many manufacturers are using this preservative as a replacement of benzoic acid. Side Effects of E202 Preservative Under some conditions, especially at high concentrations or when combined with nitrites, food additive E202 has shown genotoxic activity in vitro. To some extent, it inhibits skeletal development and could endanger kidneys and livers if it excesses the certain amount or with long-term taking. Its bacteriostatic effect is 5~10 times higher than that of the traditional sodium benzoate. Also, its toxicity is only 1/5 of that of sodium benzoate, 1/2 of salt. It will not destroy the original color, aroma, taste and nutrition of the food. This preservative can be absorbed by the body's metabolic system and quickly decomposed into carbon dioxide and water. There is no residue in human's body. As long as not exceeding the limit requirements, it is very safe. Related Articles Uses and safety of phosphoric acid EFSA: Sucralose Has No Risk of Cancer
What Is Ascorbic Acid Ascorbic acid, also known as Vitamin C, is a water-soluble vitamin, meaning that your body does not store it. You have to get it from food and beverages. It is essential for growth, healthy teeth, gums, bones, skin and blood vessels and aiding the absorption of iron. Ascorbic acid is found naturally in many fresh fruits and vegetables. Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food additives. These compounds are water soluble and thus can't protect fats from oxidation: for this purpose, the fat-soluble esters of ascorbic acid with long-chain fatty acids (ascorbyl palmitate or ascorbyl stearate) can be used as food antioxidants. Which Foods Contain Ascorbic Acid Dietary sources of vitamin C include many fruits and vegetables. Sources with the most vitamin C are fresh, raw cantaloupes, citrus fruits, kiwis, mangos, papayas, pineapples, strawberries, raspberries, blueberries, watermelon and cranberries, according to National Institutes of Health (NIH). Red and green peppers, spinach, cabbage, cauliflower, turnip greens and other leafy greens, tomatoes, potatoes, broccoli, winter squash and Brussels sprouts are other good sources of vitamin C. Benefits of Ascorbic Acid (Vitamin C) We need vitamin C for the growth and repair of tissues in all parts of the body. It helps the body make collagen, an important protein used to make skin, cartilage, tendons, ligaments, and blood vessels. Vitamin C is needed for healing wounds, and for repairing and maintaining bones and teeth. It also helps the body absorb iron from nonheme sources. As a food additive, ascorbic acid is widely used in food and beverage industry. You can find it in butter, frozen egg products, powdered and concentrated milk, frozen croquette potatoes, tinned baby foods and wine. It can also be added to products that may lose their vitamin C in processing - such as dried potatoes. It is also used as an antioxidant in the brewing industry where it improves the shelf life of beers and prevents haze development, a preservative in the meat industry where it helps maintain colour, an improving agent in the baking industry and also for inhibiting discolouration in cut fruits, fruit pulp and juices. 5 Facts about Ascorbic Acid (Vitamin C) 1. Vitamin C is sensitive to light, air, and heat, so you'll get the most vitamin C if you eat fruits and vegetables raw or lightly cooked. 2. Tablets, capsules, and chewables are probably the most popular forms, but vitamin C also comes in powdered crystalline, effervescent, and liquid forms. 3. Vitamin C is a water-soluble vitamin, meaning that your body doesn't store it. You have to get it from food everyday. 4. Ascorbic acid is considered safe, with a very low incidence of allergic reactions or other adverse effects. 5. Vitamin C acts as an antioxidant, which means it keeps foods from reacting with oxygen when they're exposed to air.
Ammonium persulfate (APS), a white crystalline solid is the inorganic compound with the formula (NH4)2S2O8. It is highly soluble in water, much more so than the related potassium salt. It is a strong oxidizing agent that is used as a bleaching agent and as a food preservative, also acts as a polymerization initiator in polymer chemistry, as an etchant and cleaner in the manufacture of printed circuit boards, as a booster in hair bleaching formulations in cosmetics and as a polymerization initiator, in soil stabilization and as a gel breaker in enhanced oil recovery systems. Ammonium persulfate is relatively easy and safe to handle. The Cosmetic Ingredient Review (CIR) Expert Panel has reviewed the use of ammonium persulfate and other persulfates as oxidizing agents in hair colourants and lighteners and has deemed them safe for brief discontinuous use followed by thorough rinsing from the hair and skin. However, it has stated that manufacturers of these products should be aware of the potential for urticarial reactions at concentrations greater than 17.5%. In a small study of hairdressers, occupational asthma (OA) was found in 51.1% and allergic occupational dermatitis in 36.2% of study participants. Ammonium persulfate was the responsible agent in 87.5% of OA cases. The average overall duration of exposure in the group of hairdressers with OA was 7 years and the average time from start of exposure to onset of symptoms was 5.3 years. Whilst just over 30% had a family history of allergic disease, none of the patients had previous occupations with possible risk factors for asthma, rhinitis, or dermatitis prior to the becoming hairdressers. Ammonium persulfate is approved for use by the Food and Drug Administration (FDA) as a multipurpose food additive in concentrations less than 0.075%. Although it has been approved for this use in the United States it is currently banned in the European Union, Australia and New Zealand as it has been found to cause contact urticaria in bakers. Generally ammonium persulfate is safe to use but some people may have an acute allergic reaction. Immediate urticaria after inhalation or contact appears to occur mainly in patients with a history of asthma. It is also evident from the study of hairdressers that repeated exposure may result in increased sensitivity to the substance, and that allergic reactions may not become apparent until after many years of exposure.
