Food additives have been used for thousands of years, ever since people realized salt could keep meat from spoiling. Today, there are more than 10,000 additives approved by the U.S. Food and Drug Administration (FDA) to preserve, package, or modify the taste, look, texture, or nutrients in foods. But increasing evidence suggests some chemicals used as food additives should be avoided―especially for children.

How do food additives affect kids?

The American Academy of Pediatrics (AAP) policy, "Food Additives and Child Health," explains that a rising number of studies suggest some food additives may interfere with hormones, growth, and development Some may also raise a child's risk of obesity. Children may be particularly susceptible to the effects of these additives, given that they have more exposure than adults due to their size and dietary intake.

Below is a list of the most commonly used food additives and the current health concerns. This list includes indirect additives, which are used in processing or packaging, as well as direct additives that are put directly into foods.

How to reduce your family's exposure to food additives

Buy fresh or frozen. It's best to buy and serve fresh or frozen fruits and vegetables when possible.

Eat fewer processed meats. Try to avoid processed meats, such as hot dogs, ham and meats in pre-packaged meals, especially during pregnancy.

Wash plastic food containers and utensils by hand, rather than in the dishwasher. Heat can cause plastics to leak BPA and phthalates into food. Avoid microwaving food or beverages―including infant formula and breastmilk―in plastic, if possible.

Use glass and stainless steel. Especially when cooking or serving hot foods, use alternatives to plastic, such as glass or stainless steel, when possible.

Learn plastic recycling codes. Look at the recycling code on the bottom of products to find the plastic type. Try to avoid plastics with recycling codes 3 (phthalates), 6 (styrene), and 7 (bisphenols) unless plastics are labeled as "biobased" or "greenware," which means they are made from corn and do not contain bisphenols.

Wash your hands. Because chemicals from plastics are so common in items we touch throughout the day, be sure to wash your hands thoroughly before and after handling food.

Speak out. Join the AAP and other organizations calling for more research into food additives' safety, including improvements to the U.S. food additive regulatory program and retesting some previously approved additives. A recent review of nearly 4,000 food additives showed that 64% of them had had no research showing they were safe for people to eat or drink. While some change to the current law could be achieved by the FDA, some may require congressional action.

Common questions from parents about food additives

How do I find out which additives are in foods?

Additives that are put directly in foods are listed on ingredient labels, but often with their chemical names. For example, salt may be listed as sodium chloride, sugar as sucrose, vitamin C as ascorbic acid, and vitamin E as alpha-tocopherol. Artificial colors are usually listed by their numbers, such as Blue #2 or Yellow #5. However, there are also indirect additives from processing or packaging materials that are not listed on the ingredient labels. These can include chemicals from plastic, glues, dyes, paper, cardboard, and different types of coatings.


Are additives a problem in any baby products?

The FDA recently banned BPA from baby bottles and sippy cups, but the chemical is still used in some food and beverage containers. Many companies have voluntarily removed BPA from their products, but in many cases replaced it with chemicals such as bisphenol S (BPS) that may have similar health effects. In 2017, the Consumer Product Safety Commission banned the use of some phthalates in child-care products such as teething rings.


Do artificial food colors cause childhood hyperactivity?

More research is needed to better understand how artificial food colors (AFCs) may or may not impact a child's behavior. This is because much of the original research on these additives were animal studies that did not include behavioral affects. For some children with attention-deficit/hyperactivity disorder (ADHD) and other problem behaviors, the AAP says that until we know more, it may be helpful to eliminate AFCs from their diet if they seem to worsen symptoms.


The future of food additives

Many new techniques are being researched that will improve how additives are produced. One approach is the use of biotechnology, which can use simple organisms to produce food additives. These additives are the same as food components found in nature.

Talk with your pediatrician

Although there are ways to limit the amount of potentially harmful food additives in your family's diet, stronger federal food safety requirements will help keep all children healthy

If you're concerned about food additives, talk with your pediatrician. Your regional Pediatric Environmental Health Specialty Unit (PEHSU) have staff who can also talk with parents about concerns over environmental toxins.

There are many different methods used to produce natural plant extract powder. Durning an extraction process a solvent is used to draw out the plant extracts, common solvents utilised are water or alcohol. Once the desired compounds are extracted the solvent is then removed. The plant extraction method used depends on whether specific compounds of the plant are desired to be extracted or the full range of plant compounds. Here we take a close look at the different methods of extraction.

1. LIPOPHILIC EXTACTION // Lipophilic are oil loving (fat soluble) and therefore soluble in oil. Macerated or Infused oil are Lipophilic extracts. This includes fat soluble vitamins (A, D, E, K), carotenoids, bisabolol and other lipophilic active ingredients. Note: Vitamin C is an extremely sensitive hydrophilic vitamin and therefore it is NOT present in plant oils, however some plant oils exhibit Vitamin C behaviours, research, I am sure one day may explain these 'effects'.

HOW IT WORKS // Plant material is added to a carrier oil. Maceration is performed as cold or warm-cold. Usually the procedure takes a few days to several weeks and the plant material is renewed several times during the maceration period. Heat or sun are applied as sources of energy.
Ingredient Example // St Johns Wort Infused Oil

2. SUPERCRITICAL EXTRACTION (CO2) //Supercritical extraction uses CO2 (Carbon dioxide - an oxygen-free process) instead of organic solvents.

HOW IT WORKS // At a temperature and pressure above its critical point, a molecule will become a supercritical fluid, which is not quite a gas, but not quite a liquid. Supercritical fluids can be used under high pressure to extract a full range of phytochemical types. CO2 has a high diffusion rate that can penetrate the material quickier than liquids. It is a pure substance found in nature and is, thus, easily removed from the final extract without leaving any residue.

Among its advantages, supercritical CO2 extraction has the flexibility to extract specific compounds, and it operates at temperatures lower than expeller press and organic solvent methods. It also involves no oxygen, thus better preserving the extracted compounds.

CO2 extraction delivers the superior active properties of the plant without the use of any chemical solvents or the production of residues & impurities or issues with rancidity. Supercritical CO2 extraction is not ideal for all ingredients, this method is only applicable to materials that are lipid soluble.

A natural instant fruit juice powder is a powder made from the juice of fresh fruit and then dried into a fine powder. Fruit juice powders are basically concentrated fruit juice dehydrated by spray-drying method. Its moisture content is 1%-3%. The spray drying process is considered a conventional method to convert fruit juices to powder form. It can be used in drinks, dressings, marinades, desserts, smoothies etc. One must not get confused between fruit powder and fruit juice powder as the two are totally different. Powders are made from drying the whole fruits while fruit juice powders are made from drying the pure juice.

What is an API?

An API is defined as a specification of possible interactions with a software component. What does that mean, exactly? Well, imagine that a car was a software component. Its API would include information about what it can do—accelerate, brake, turn on the radio, etc. It would also include information about how you could make it do those things. For instance, to accelerate, you put your foot on the gas pedal and push.

The API doesn't have to explain what happens inside the engine when you put your foot on the accelerator. That's why, if you learned to drive a car with an internal combustion engine, you can get behind the wheel of an electric car without having to learn a whole new set of skills. The what and how information come together in the API definition, which is abstract and separate from the car itself.

One thing to keep in mind is that the name of some APIs is often used to refer to both the specification of the interactions and to the actual software component you interact with. The phrase "Twitter API," for example, not only refers to the set of rules for programmatically interacting with Twitter, but is generally understood to mean the thing you interact with, as in "We're doing analysis on the tweets we got from the Twitter API."
