Aloe Vera Quality Certification Analysis Quality Control

Aloe Vera Services.  CEAMED a complete service for the analysis of aloe vera. These studies include both

  • Physico-chemical analysis.
  • and Microbial analysis.

Why analyze Aloe Vera?

There are 3 main reasons why the quality of aloe should be measured:

  1. It has been scientifically proven that the positive biological effects of aloe correlate with its quality. Poor quality aloe has no, or significantly reduced biological effects, compared to high quality aloe.
  2. Adverse (or unwanted) biological effects are more common with poor quality aloe (especially those with relatively high aloin levels).
  3. Fraudulent practices (addition of bulk adding substances or dilutions) have been recorded within the aloe industry that generates aloe products of poor quality.

In order to combat the sale of poor quality aloe some organizations have established certification processes.
For example, the International Aloe Science Council (IASC) establishes that an "Aloe Vera" product must contain at least 5% of the polysaccharide acemannan, have <10 ppm of aloin, be free of degradation products and comply with bacterial limits.

Why choose CEAMED for your Aloe Vera analysis?

There are 2 main reasons:

  • CEAMED Offers ISO 9001 certified analysis of aloe vera
  • CEAMED routinely provides analysis for more than 26 producers of aloe from all over the world (Europe, Asia and the Americas)
United Registrar of Systems URS ISO UKAS Management Systems

1. Chemical analysis.

Using High Performance Liquid Chromatography (HPLC) and nuclear magnetic resonance techniques (NMR) we can determine the quality (levels of "good" components, degradation products and aloin) of an Aloe vera sample (see table for details).
The main components of Aloe Vera



Acemannan =Aloverosa

"Active" component from Aloe vera


IASC requires <10 ppm for consumption

Malic acid

Natural component of aloe vera "good" component

Isocitric acid

Whole leaf marker

Isocitric acid lactone

Whole leaf marker

Lactic acid

Degradation products (sign of poor quality)

Pyruvic acid

Degradation products (sign of poor quality)

Acetic acid

Degradation products (sign of poor quality)

Succinic acid

Degradation products (sign of poor quality)

Fumaric acid

Degradation products (sign of poor quality)


Degradation products (sign of poor quality)

Potassium Sorbate


Sodium Benzoate




Total polysaccharides

Good component

Heavy Metals (Hg, Pb, Cd, As)

Levels are regulated by laws

2. Microbiological analysis.

Aloe vera products, especially beverage and food additives should be free of bacteria. We can perform these tests for you.
Each sample analyzed will be issued with a report detailing the results and the conclusions derived thereof, as well as technical and scientific indications that may be appropriate for product improvement.

3. Consultancy:

CEAMED can advise their clients how to improve their products (levels of aloin and acemannan) by suggesting changes to their production process.

4. Education:

Presentations are also available in order to improve the knowledge of the staff about Aloe vera. Themes include:

  • components of Aloe vera
  • identification and quantification of constituents
  • regulations on the content of Aloe vera products
  • production processes and additives used in industry
  • Uses and abuses.

FAQ Frequently asked questions from our customers

Centro Atlántico del Medicamento (CEAMED, SA) is an independent laboratory that, among its services provides chemical determination of the levels of acemannan (aloeverasa), aloin and other substances, using Nuclear Magnetic Resonance (NMR) and High Performance Liquid Chromatography (HPLC) techniques.

  • How long do the analysis of acemannan and aloin take?
    • If you want to determine both substances, the analysis can be done in 4 or 5 days, from receipt of the sample. If you only want to analyze one of the substances, the analysis takes 4 days.
  • What amount do I need to send to perform the analysis?
    • With 50 mL of aloe juice (1X) both determinations can be made. With less quantity, relative errors increase and the data obtained from the analysis may not be exact.
  • How do I send my sample to the laboratory?
    • It is recommended that the sample of aloe juice be transported in a closed, opaque (not transparent to light) recipient.

Shipping costs are included in the price of the analysis, so you should contact CEAMED to arrange a date for sample collection.
