As a matter of principle we do not use enzymes in order to have fat (lipases), protein (proteases), and amylum (amylases) degrade more easily at low temperatures.
Enzymes are to be found in almost every conventional laundry detergent as well as in all of the dishwasher detergents. Enzymes are proteins occurring in all plants, animals, and humans. They are involved in every metabolic process. Therefore, enzymes are no chemical substances dissolving or binding dirt; they rather act as organic catalysts that virtually “eat up” dirt. They are isolated from fungi or bacteria.
This constitutes a major problem. Enzymes are integrated in a live organism and fulfill their specific function. They represent a harmonious component of the respective living organism. If they are detached from this organic correlation to achieve a certain effect, enzymes are no longer able to distinguish for example between greasy food residues and human cutaneous lipids, and, via enzyme residues in the dry laundry, at random attack the skin wherever it is most moist, i.e. in the neck, elbow, arm pits, etc. thus resulting in sensitisations which, in turn, may cause allergies.
Furthermore, there is the problematic nature of genetic engineering as such. Nowadays almost 100% of all enzymes used in laundry detergents are derived from GMOs. If such organisms, artificially modified by man to extreme imbalance, were to integrate into the environment, the consequences thereof would be unmanageable and irreversible.
We have come to consume metabolic products of these manipulated organisms as “lab ferments” in Swiss high-quality cheese, as a fermentation accelerant in French champagne, as a baking aid in our bread and as “valuable vitamin supplements” in so-called functional food.
The most recent development takes one more step toward manipulation.
Even the protein structure of the enzymes is genetically modified, so that the enzymes thereof no longer occur naturally; the justification for this even farther-reaching manipulation of the organism being, amongst other things, improved resistance to heat or increased compatibility with bleaching agents.
Beware of the label: „enzymes guaranteed not to be genetically modified“!
This description is used for enzymes which do indeed originate from GMOs but the protein structure of which has not been modified.
