Our Best-Selling Food Additives
Α-ketoglutaric Acid
Α-ketoglutaric acid (AKG), as an endogenous metabolite in human body, is an intermediate of tricarboxylic acid cycle, and a most important precursor for the synthesis of amino acids and proteins. AKG is widely applied in human nutrition, animal nutrition and personal cares.
Calcium α-Ketoglutarate
Ca-AKG, or calcium α -ketoglutarate salt, is a form of AKG and is often used in supplements. α -ketoglutaric acid (AKG) is a naturally occurring molecule that is crucial for various metabolic and signal transduction processes and pathways in our cells. For instance, AKG is a key participant in tricarboxylic acids (TCA), which connects most cellular processes, such as energy production, synthesis, and the degradation of various molecules.
5-aminolevulinic Acid
5-aminnolevulinic acid (5-ALA, C5H9NO3, MW:131.13, CAS No.:106-60-5) is an organic compound containing oxy-gen and nitrogen elements.
Give the food a smooth and consistent texture:
- Emulsifiers prevent liquid products from separating.
- Stabilizers and thickeners provide an even texture.
- Anticaking agents allow substances to flow freely.
Improve or preserve the nutrient value:
- Many foods and drinks are fortified and enriched to provide vitamins, minerals, and other nutrients. Examples of commonly fortified foods are flour, cereal, margarine, and milk. This helps make up for vitamins or minerals that may be low or lacking in a person's diet.
- All products that contain added nutrients must be labeled.
Maintain the wholesomeness of foods:
- Bacteria and other germs can cause foodborne illnesses. Preservatives reduce the spoilage that these germs can cause.
- Certain preservatives help preserve the flavor in baked goods by preventing the fats and oils from going bad.
- Preservatives also keep fresh fruits from turning brown when they are exposed to the air.
Control the acid-base balance of foods and provide leavening:
- Certain additives help change the acid-base balance of foods to get a certain flavor or color.
- Leavening agents that release acids when they are heated react with baking soda to help biscuits, cakes, and other baked goods rise.
Provide color and enhance flavor:
- Certain colors improve the appearance of foods.
- Many spices, as well as natural and man-made flavors, bring out the taste of food.
Solvent Extraction
Commonly used for plant-based pigments, this method uses food-grade solvents like ethanol, water, or oils to dissolve and separate the pigments from the plant material. The choice of solvent depends on the solubility of the pigment.
Steam Distillation
Used mainly for volatile compounds like essential oils, steam distillation helps in extracting colors and aromas by passing steam through the raw material.


Cold Pressing
Often used for extracting oils and color from seeds or fruits, this mechanical method applies pressure without heat to preserve the natural color and properties of the extract.
Enzymatic Extraction
This process uses enzymes to break down plant cell walls, releasing pigments more efficiently. It’s particularly useful for delicate materials that may be damaged by harsher extraction methods.
Principles for Using Food Additives
The food additives being used should present no risk to the health of the consumer at the levels of use.
The use of food additives is justified only when such use has an advantage:
● To preserve the nutritional quality of the food.
● To provide necessary constituents for foods manufactured for groups of consumers having special dietary needs.
● To enhance the keeping quality or stability of a food or to improve its organoleptic properties.
● To provide aids in the processing, packaging, transport or storage of food, provided that the additive is not used to disguise the effects of the use of faulty raw materials or of undesirable (including unhygienic) practices of techniques during the course of any of these activities.
All food additives shall be used under conditions of good manufacturing practice (gmp) which include the following:
● The quantity of the additive added to food shall be limited to the lowest possible level necessary to accomplish its desired effect.
● The quantity of the additive that becomes a component of food as a result of its use in the manufacturing, processing or packaging of a food and which is not intended to accomplish any physical, or other technical effect in the food itself, is reduced to the extent reasonably possible.
● The additive is prepared and handled in the same way as a food ingredient.
Storage
Food additives should be stored in a cool, dry place, out of direct sunlight, and kept tightly sealed. Properly sealed packaging prevents contamination and protects against environmental factors that could compromise product integrity. It is recommended that additives be stored in their original containers and clearly labeled packaging to avoid mix-ups and ensure traceability.
