About Enzymes

• There is a sizeable global market for industrial enzymes
• Thousands of tons of industrial enzymes are produced and used annually
• These industrial enzymes are:
  
  1. Powder enzymes sold in boxes or drums
     
  2. Liquid enzymes sold in Jerry cans or drums

Statement on storage/shelf life of industrial enzymes

1. Industrial enzymes sold by Science Technics are formulated with stabilizers.
   These stabilizers vary from enzyme to enzyme. Due to the presence of stabilizers it is not essential for the enzymes to be maintened cold.
2. When enzymes are packed and sent to customers they have a certain “overfill” over the declared activity on the product sheet. This “overfill” is typically 5-10%.
3. When these enzymes are stored in a cool place (eg. air-conditioned room) they lose about 1% of their activity per month.
4. When these enzymes are stored in a fridge (not frozen) they lose less than 0.5% of their activity per month.
5. When stored in a cool place or refrigerator these enzymes can be used at the dosages recommended in application sheets for up to one year from the date on the certificate of analysis.
6. Beyond one year these enzymes can still be used. However the dosages are typically increased by 1% for each additional month stored beyond 12 months from certificate of analysis. This compensates for activity loss.
7. Good Manufacturing Practice dictates that industrial enzymes are not used beyond 24 months from date of analysis.
8. In practice this is not a problem – industrial purchasers typically purchase monthly or bimonthly.
9. Under no circumstances should these enzymes be subjected to high temperatures during storage.
10. Do not make “stock solutions” or dilutions of enzymes to be stored. In such “stock solutions” or dilutions the concentration of stabilizers is much lower and the stability of the enzyme is very poor; activity can be lost in hours or days.
11. Accidental freezing of liquid enzymes does not harm them. However on thawing these frozen enzymes some separation may occur and a thorough mixing is required.
12. When powdered enzymes are stored in a fridge please wait for the bottle to attain room temperature before opening. Atmospheric moisture will condense on cold enzyme granules and cause lumping.

Statement on Heavy Metal Analysis and Microbiological Analysis of Bake Plus B111

Science Technics Sdn bhd produces a range of enzyme powder blends containing enzymes, emulsifiers, stabilizers in a carrier of tapioca starch or maltodextrin.

All components of our blends are food grade materials.

To satisfy legal requirements our company samples our blends and sends samples to an accredited external laboratory for microbiological and heavy metal testing.

Such testing is done yearly or at the request of customers.

Typically the following test are done

• Microbiology
  1. Aerobic Plate Count
  2. Yeast and Mould Count
  3. Coliform (Solid Medium Method)
  4. Salmonella (Solid Medium Method)
  5. Escherichia coli Count
• Heavy Metal
  1. Arsenic
  2. Lead
  3. Cadmium
  4. Mercury
  5. Antimony
