EFFECT OF PH
FAA-5000 can effectively hydrolyze starches at a pH range from 4.0 to 6.5, with the optimum pH range being 4.8 to 5.4. If greater enzyme stability is preferred, the reaction should be conducted at a pH above 5.5; if a faster reaction rate is desired, the pH should be kept below 5.5. Its pH optimum will depend on several process variables such as time, temperature, substrate concentration, and dough moisture levels. Figure 1 shows the effect of pH on FAA-5000 activity.
EFFECT OF TEMPERATURE
FAA-5000 can effectively hydrolyze starch at temperatures from 45°C to 55°C, with its optimum temperature at 50°C. Its optimum temperature depends on the actual processing conditions such as time, pH, substrate concentration, moisture, etc. Figure 2 shows the effect of temperature on FAA-5000 activity.
The temperature versus activity profile of FAA-5000 matches well with the demand for sugars needed by the yeast during the dough fermentation. As the dough begins to ferment, the activity of the FAA-5000 and the yeast will be enhanced as the temperature rises (i.e. the Fungal Alpha-Amylase constantly hydrolyzes the soluble starchescontained in the dough and produces monosaccharides to support yeast proliferation, thus increasing the fermentation speed and improving the dough quality). When fermentation of the dough is completed and the semi-products begin to be steamed or baked, the yeast will become inactivated at 60°C and FAA-5000 will lose its activity as well (thus avoiding excessive saccharification of the dough which might otherwise lead to undesirable stickiness of finished products).
Inactivation of FAA-5000 can be achieved by maintaining the temperature at 90 to100°C for 5 to 10 minutes. If the starch content is high, FAA-5000 can be inactivated by maintaining the temperature at 80°C for about 30 minutes, or at 70°C for about 60 minutes.
FAA-5000 is used to extend the shelf life of bread and baked goods. Adding FAA-5000 to dough can result in magnified product volume as well as improved texture and appearance.
The recommended dosage is 0.02～0.05% of flour by weight. The exact dosage will vary among bakeries depending on the kind of flour, the specific formulation, the type of equipment and processes. In practice, it is recommended to conduct baking trials to determine the optimal dosage.
It is important that proper dispersion and mixing of FAA-5000 is achieved to obtain optimal efficiency of the enzyme performance in the process. Due to the small dosage required, it is recommended to premix FAA-5000 in a dry state first with a small amount of flour, and then add it to the batch over a long enough period of time so as to ensure even mixing with the flour. It is also acceptable to add the enzyme directly to the dough.

STORAGE AND SHELF-LIFE
Best before The product is best used within 6 months from date of delivery provided it is stored as recommended. Storage at customer's warehouse 0 ~ 25°C
Typical shelf-life is six months if it is stored below 25°C in its original packaging, sealed and unopened, protected from direct sunlight. Its shelf-life will be eighteen months if it is stored properly at 0 ~10°C. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, therefore should be avoided.
SAFETY AND HANDLING PRECAUTIONS
Inhalation of dust or aerosols should be avoided due to enzymes may cause allergic reactions in sensitized individuals. Splashing should be avoided. Spilled product should be flushed away with water immediately. Wear suitable protective gloves, safety glasses and nose covers. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. Refer to the Safety Data Sheet for further information regarding how to handle the product safely.
