Food Pigments: Classification, Challenges, Concerns and Health benefits
Introduction:
Food pigment or food colorant is a color additive that added to food or drink to impart color. In addition, any chemical that reacts with another constituent produce a color is also considered in the class of food pigment.
Natural food pigments are prevalent in plants, animals and microorganisms. These natural pigments enhance the visual appeal of raw food to where colors are associated with the quality of food.
Artificial food pigments are used in food due to two main reasons. The main reason is to compensate for the loss of the natural colors due to the physical parameters of light, temperature, air and storage conditions. The second reason is to make the food more attractive by enhancing the existence natural colors or by the giving a color to

Health benefits associated with artificial food pigments
Recently controversial studies reported a possible useful mechanisms for some artificial food pigments. In this regard, anti-inflammatory and anti-depressant effects were reported fore Brilliant Blue (Ma, Ren, Zhang, & Hashimoto, 2014).
Classification of the artificial food pigments:
Artificial food pigments could be classified according to their color to four main groups, blue, red - orange, yellow and green – white group. Table 1 shows the most used food pigments in each group and their relative ADI values and applications. The lowest ADI values were reported to the red to orange group of pigments with ADI values between 0.1 and 0.8 mg/kg b.w. making this group the most dangerous pigments, followed by the green-white group (with ADI values between 0.1 and 0.8 mg/kg b.w), then the yellow group and finally the blue group is the less dangerous
The essential points of the green-frosting are the concentration and absorbance value in each diluted which the process of serial dilution. The standard curve of Blue#1 and yellow #5 provide the equation of the trend-line in order to calculate the concentration in the diluted solution of the green frosting. The mole of dye in 100mL green stock solution, mole of dye in 5 gram and 1 gram of frosting, the Beer –Lambert Law, and the compare to amount desired by the company can be determined. The Beer-Lambert Law is the relationship between color and the concentration and equation A=Ebc. The “A” is absorbance, the “C” is a concentration in molarity, the “E” is a molar absorptivity and “b” is the path-length. The goal of the lab is to use the absorbance and the Beer-Lambert law to determine the amounts of blue#1 and yellow #5 in the green frosting.
One out of every 20 Americans will become depressed this year. This is obviously a very major and serious problem. St. John’s Wort’s main ingredient, hypericin, is what appears to help alleviate mild to moderate depression, although not much is known about whether or not it proves helpful in severe depression. Hypericin is the red pigment of the plant and it seems to inhibit monoamine oxidase (MAO) and the breakdown of the brain’s neurotransmitters and is also a SRI, serotonin reuptake inhibitor. However, according to Jean Carper in Miracle Cures, “recent research finds hypericin less potent an antidepressant than the whole plant extract itself, suggesting the herb’s complex mixture of chemicals, including xanthones and flavonoids, also are critical in the plant’s pharmacological benefits”.
PURPOSE: The purpose of the experiment is to determine the specific types of pigments found in water-soluble marker pens by using paper chromatography and water as a solvent.
Experiment #3: The purpose of this experiment to test the chromatography of plant pigments the alcohol test strip test will be used.
...ome serious genotoxic damage in the humna body at even a rather small dosage. Children suffering from ADHD are exposed to a very high risk of worsening symptoms when consuming the right amount of artificial food dyes. On other occasions, food dyes can be responsible for other, more serious cases such as cancer. As time goes on, new information is found that helps people become more and more educated on the world around them, yet, humanity is still oblivious to the things they put in and around their body. It would be apparent that people would care more about the health and safety of them and their children rather than the appearance of their food, however, the people refuse to give up the disguise of the artificially colored foods and see the true risks at hand. It is humanity that overlooks health and safety for colorful foods; one day humanity will have to learn.
Aspartame has been known as one of the most famous sweeteners and additives to food. Since its discovery in 1965-1969, it has now been developed into a commercial product in which several products use it to enhance its sweetness and taste. Because of this, it has also been a very prosperous commercial product where its company developers get much profit on. Nonetheless, it has been the subject of issue and controversy. Several reports and studies rebuke the suitability of it being a food product stating that it is more known as a poison. Therefore, in this essay, the advantages and limitations of Aspartame as a chemical food additive will be analyzed and evaluated with regards to Economic and environmental factors. Also, the physiological effect of this chemical additive will be looked upon and discussed.
Food coloring is typically used in food and drink products. Another term used for food coloring is artificial color. It is added to give the product a certain colored appearance. Food coloring can come as a gel, paste, liquid, or powder. Food coloring contains various chemicals but is often based from petroleum
Cocoa solids are valuable for their flavanol antioxidants and alkaloids which have physiological effects on the body and influence the levels of serotonin in the body meaning that they simply bring the perception of “happiness”. Chocolate is one of the most popular foods in the world and is applied widely in the food industry.
It changes from blue to red with acids but loses its colour in the presence of certain chemicals, one of which is vitamin C. DCPIP solution can be used to test for the presence of vitamin C in foods. Hypothesis Orange juice has the highest content of vitamin C. Citrus fruits have a higher content of vitamin C. The orange and lemon juice contain more vitamin C than the pineapple juice. Furthermore, as lemons are more acidic than oranges, I predict that the orange juice will contain more vitamin C than the lemon juice. Vitamin C affects, the ph the more vitamin C the higher the ph. Variables Independent Variables Different fruit juices (Pineapple, orange and lemon).
Food has been a common source of necessity in our everyday lives as humans. It helps gives us nutrition and energy to live throughout our life. Over several decades, the development of making foods has evolved. They have changed from natural to processed foods in recent years. Nowadays natural ingredients are barely used in the making of foods like bread, cheese, or yogurt. The food industry today has replaced natural food making with inorganic ingredients. The cause of this switch is due to processed foods being easier, cheaper and faster to make. Artificial nutrition and processed foods have been proven to last longer in market shelves then natural foods. Also, due to artificial additives in processed foods they help satisfy consumers taste more than natural ingredients. The method of producing processed foods is common in today's food industry and helps make money faster and efficiently for companies. Examples of this can be found in all markets that distribute food. Even though processed foods may be easier and faster to make, they are nowhere near as healthy for consumers compared to natural foods. Natural foods are healthier, wholesome, and beneficial to the human body and planet then processed foods.
Food is “composed of synthetic chemical additives, such as colorings, preservatives, sugar substitutes and trans-fats” (Fitzgerald, 2006, p.72). Fitzgerald reported that by the “1970s most meats and dairy products that were factory farmed were laced with growth hormones, antibiotics and a range of pesticides” (p.72). Furthermore, food that is frozen, packaged and canned is considered processed food. A brief explanation of the chemical additives in processed food. 1.

Processed foods dominate a large area of the modern food world. Food processing is any intentional change in a food item before it is available to consume, and could be as simple as freezing or drying food to preserve it to formulating a complicated food product with
It is known to make the hair shine, the skin glow, and the bones strong and good for the eyes. Two other fundamental substances found in glow foods are fiber and antioxidants. Solvent fiber supports in great assimilation, brings down awful cholesterol and keeps up glucose levels. The cell reinforcements, including vitamins A, C, E and selenium, help the body battle cell harm and reinforce the safe framework.
Food Preservation is the ways to retain the food quality in a longer times. It is to prevent the food decomposition and fermentation. Besides that, food preservation not only to prevent the food getting spoilt in a long period of time but also preserved the colour, taste and the food nutritive value. Nowadays, food preservation has become more and more important component in the food industry as the consumers expect that able to purchase those foods that are out of season or imported from other countries. Furthermore, there are few reason why food preservation is important in our daily life such as preservation foods when they are in season it may added variety choices in our meals for example smoke meats and
