It seems that cereals is the most commonly listed food in breakfast, but do you know what ingredients are used in cereals? You may have read the ingredients label and noticed some ingredients that do not look like they belong in the cereal we eat, and one of them is the trisodium phosphate. Then you may have the questions about this doubtful stuff in your food. First, what is trisodium phosphate? Trisodium Phosphate is the inorganic compound Na3PO4, also known as TSP, trisodium orthophosphate or simply sodium phosphate. It is a white, granular or crystalline solid and mostly come in form of white powder. Trisodium phosphate can serve as a food additive (E339) and can also be found in daily consumer products such as toothpastes, dental cleansers, shampoos, cosmetics, and bleaching agents. As a nutritional supplement, TSP can also improve performance in sports players. Why is trisodium phosphate used in cereal? Trisodium phosphate can act as the acidity regulator and reduce the acid nature of the food and can always be found in in dry and extruded cereals. It can also modify the cereal color and aid in the cereal’s flow through the extruder. When used with other phosphates, it can help provide phosphorus fortification. And TSP can also be used as an emulsifier in cheese. Is trisodium phosphate in cereal safe? Since trisodium phosphate is widely used in food industry such as fruit drinks, dairy product, canned foods, meat, kids cereals and cheese, the safety issue and side effects of STP are concerned by more and more people. The United States Food and Drug Administration (FDA) lists sodium phosphates as "generally recognized as safe." The FDA allows TSP in our food and personal care products and it is not a risk in certain amounts. The use of TSP in food is also clearly defined according to the Chinese hygienic standard. For the canned foods, juice drinks, dairy products and vegetable protein beverages, the maximum use is 0.5 grams per kilogram; for meat, the maximum quantity is 3.0 grams per kilogram; for cheese, the maximum amount is 5.0 grams per kilogram; for drinks, the maximum use is 1.5 grams per kilogram. TSP will become alkaline when it is dissolved in water, therefore, excessive dosage in food will not only destroy the nutrients in the food but also endanger health. TSP as a food additive has not been proven to be toxic to humans, and the reasonable use of TSP in cereal is safe.

Gelatin is made of the degradation of the collagen part in skin, bone, sarcolemma, muscle and other connective tissue of animals. It is a white or light yellow, translucent, micros trip shiny sheet or powder. Therefore, it is also called animal gelatin or fat glue. Industrial gelatin is colorless or pale yellow transparent or translucent sheet or powder. It is tasteless and odorless. Moreover, gelatin can swell in cold water and dissolved in hot water. It is soluble in glycerol and acetic acid, while insoluble in ethanol and ether. Water and inorganic salts in gelatin account for about 16%, and protein content accounts for more than 82% in Gelatin. Similar to maternal collagen, gelatin is also made of 18 kinds of amino acids, in which, the content of Pro and hyp in amino acids is higher. The three-helix structure in gelatin gel is mainly composed of hydrogen bonds and hydrogen bond hydride. Pro--NH, Hyp-OH and other amino acid side chain groups and water molecules can form hydrogen bonds, and structural stability. Gelatin can be divided into skin gelatin and bone gelatin according to the raw materials. Skin gelatin can be subdivided into bovine skin gelatin, pig skin gelatin, chicken gelatin, fish gelatin and so on. What’s more, bone gelatin can be subdivided into bovine bone gelatin, pig bone gelatin, chicken bone gelatin and fish bone gelatin. Scale gelatin is a kind of gelatin extracted from fish scales in recent years. Gelatin is a macromolecular hydrophilic colloid. It is a kind of low calorie health food with high nutritional value. It can be used as confectionery additives, frozen food additives and so on. Based on the difference of raw materials, production methods, product quality and usage, gelatin can be divided into edible gelatin, medicinal gelatin, industrial gelatin, photographic gelatin, leather gelatin and bone gelatin. In industrial usage, it is customary to use the protein for the extraction of hydrolyzed animal protein called animal gelatin, in feed additives called feed gelatin, and in match industry called match gelatin. Moreover, for the packaging and other products of hot gel gelatin, it is called hot melt adhesive powder.
People usually refer to a horizontal row on the periodic table as a period, which means that the outermost electrons of the elements on the horizontal rows of the periodic table are circulated from one to eight; the vertical columns of elements are called groups, which means that the elements in the vertical columns with the same number of electrons in the outermost layer have similar properties. Scientists use this method to classify different elements, infer the relevant chemical properties according to the period and group of elements, and study the periodic table to summarize the rules applied in daily life. For example, it is found that Al and Be are amphoteric elements with almost the same properties by the diagonal rule. Figure 1 Periodic Table of Elements The period and group of elements on the periodic table are divided according to the atomic structure of the elements. The scientists place the members with the same electron shell number in the same horizontal row as a period (See Figure 1). In order to have an easy understanding, you can imagine the structure of the atoms as the orbital graph of the solar system. The nucleus in the atomic center takes up most of the weight as the "sun", while the extra-nuclear electron layers are equivalent to the Earth, Jupiter, and Saturn just like "stars movement track". According to the distance between the “sun”(nucleus) and “stars”(layer), the first layer can be indicated as K, the remaining second and third layer can be L and M. The elements with the same electron layer number are in the same period, which means the number of electron layers in the same period is the ordinal number of the period. For example, all the elements with the electron layer represented by K can be expressed in the first period. At the same time, the scientist places the elements with the same electrons on the outermost layer in the same vertical column of the periodic table as a group (the Ⅷ group includes three columns). The electron number of the atomic and atomic number are the same. The first layer can put two electrons, the outermost layer can put 8 electrons, and the outer layer can put 18 electrons.When their outermost electrons are identical, they will be in the same group (see Figure 2). In general, the elements of the same group always have similar chemical properties, like the halogen elements, alkaline earth elements and alkali metals.

Citric acid is widely used in our life, in this article we are going to talk about it in the following aspects: What is citric acid? Citric acid is a weak organic acid and always comes in form of white crystalline powder. According to the different water content, it divides into citric acid monohydrate and citric acid anhydrous. What can citric acid be used for? Citric acid is often used in food, personal care and pharmaceutical industry. According to IHS research, about three-quarters of the world consumption of citric acid is in beverages and food, and approximately 13% of the citric acid market is in household detergents and cleaners. In food industry, citric acid is the most widely used food preservative and flavor enhancer in beverages. Citric acid is used to control the growth of microorganisms, adjust acidity (pH), provide sourness and tartness, and enhance flavors. The acidic pH of citric acid makes it useful as a preservative. Citric acid is also used in soft drinks, teas, juices, and other beverages to create a slightly tart, refreshing flavor and balance sweetness. Because citric acid can be made in a powder form, it can also be used in dry foods when a sour flavor is desired. Because citric acid kills bacteria, mold, and mildew, it's great for general disinfecting and cleaning. It’s also very helpful in cleaning hard water stains and kitchen messes. One of the most well-known use of citric acid is home made bath bombs, along with baking soda. Citric acid is also widely used in other industrial sectors, such as cosmetics and pharmaceuticals, dyeing, photography and synthesis solid materials from small molecules. Where to buy citric acid? Organic citric acid is obtained especially from citrus fruits, like lemon and lime juices. But it’s not economical for industrial use. Most citric acid in bulk is a commodity chemical produced by feeding simple carbohydrates to Aspergillus niger mold and then processing the resulting fermented compound. China is the largest producer and the top exporter of citric acid (HS code: 29181400) with the production about 72% of the total output and takes up 86.8% of global citric acid export volume in 2016. Therefore, most of the citric acid used on the global market is from China. So the best answer to the question is China.
