Therefore, even
if the testing procedure of the unsafe sample is relatively simple,
it must be done with proper management with the right sample; such
as
Randomly choosing samples from manufacturing and supplying sources.
Information on the amount of sample tested the preparation of the sample
(details available on the GT test kit brochure). This is to ensure
the correct test results and to cover all kinds of vegetables. This
semi-fast testing method tests for toxicity using the Acetyl Cholinesterase
Technique (details available in the manual*).
The theory suggests that
the toxic in the phosphate group and/or carbamate is distinct in
its ability to halt the mechanism of the enzymes in the body. When
the
body receives these toxins, it will not function properly. We use
this fact as a preliminary test for toxicity to filter out the 2
groups
of chemicals that are commonly used.
However, investigation on this method shows that the method is
not only specific to chemicals in these 2 groups, it will also
test positive
against other toxin such as the toxicity in some herbs. These herbs
include old red seed of the Bitter Cucumber (Momordica Charantia
Linn) or Biodegradable products or toxicity that resulted when
low-intensity toxin comes into contact with plant cells. This
is a great step towards
protecting the consumer. Therefore this method is different from
the
methods used in labs that tests and analyzes the safety of the
chemical by comparing chemical levels with the type of food.
If the chemical
level doesnt exceed the danger level, then it is declared safe.
However, the example mentioned above is being debated whether the
consumers will be safe from receiving toxin from food with more
than 2 types
of chemicals or not. Another problem comes when there is a chemical
in the food that does not have a set danger-level-value. This
will cause confusion in determining the safety of the toxicity-level
in the food. Experienced personal would be required for this
task.
The main feature of the basic test kit involves testing the toxic
residue of the sample, whether its an insecticide, or toxic from
plant cells and some chemicals that causes toxicity. There is also
a designated safety level, derived from the toxicity of one chemical
or the toxicity of the combined chemicals. These toxins also have
the ability to reduce the performance of the enzymchlorineesteres
by 50% in terms of its ability to test a small amount of chemicals.
The tester is then able to determine by him/herself whether the sample
tested is safe or not.
