Neutral Protease

DESCRIPTION
Glucoamylase PUREMEI PG is made from NON-GMO strains of Aspergillus niger through submerged fermentation, extraction and refining processes. PUREMEI PG has a high conversion rate of starchy substrates into fermentable sugars. It can hydrolyze a-D-1, 4 glucosidic bonds from the non-reducing end of starch one after. It can also hydrolyze the a-D-1, 6 glucoside branch bonds of starch and cleaves the a-1, 3 bonds to release glucose.

PUREMEI PG is designed with a robust glucoamylase activity for saccharification in fuel ethanol production. Use of PUREMEI PG provides higher ethanol yields, faster fermentations, and lower residual starch levels.

PRODUCT CHARACTERISTICS
Declared Enzyme: Glucoamylase
Systematic Name: EC 3.2.1.3, 1,4-alpha-D-glucan glucohydrolase
Appearance: Sepia brown liquid
Activity: 130,000 U/ml (minimum)
Product pH: 3.0 to 5.0
Specific gravity: 1.10 to 1.20 g/ml

EFFECT OF PH
The optimal pH for PUREMEI PG is 4.0 to 4.5.

EFFECT OF TEMPERATURE
The effective temperature range for PUREMEI PG is 30 to 65°C. The optimal temperature range is 55 to 60°C.

PRODUCT APPLICATIONS AND BENEFITS
PUREMEI PG is used to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca. The resultant glucose product is fermented by yeast or another appropriate microorganism to yield ethanol.

For ground-grain processing plants using simultaneous saccharification fermentation (SSF), PUREMEI PG may be added directly to the fermenter. For ground-grain dry mill plants and for wet mill plants using a separate pre-saccharification step prior to fermentation, PUREMEI PG may be added to the cooling mash or liquefied starch when the temperature reaches 55 to 60°C. Temperatures above 65°C can result in loss of activity rapidly.

DOSAGE GUIDELINES
PUREMEI PG is generally added at a level of 0.065 to 0.085% w/w (dry solids basis). The actual dosage depends on the actual processing conditions including raw materials, temperature, reaction time, pH and the desired results in individual ethanol plants.

Beer enzyme complexed

Product presentation

Beer enzyme complex aka606 consist of the excellent resist high temperatureªG-dextranase, xylanase, neutral protease, cellulose enzyme, neutral temperature ªß-amylase, etc.

Prodcut character
This product have some function as follows:resolve dextranase and pentosan enzyme, reduce the viscocity of malt juice, increase filter speed and the clear of wheat juice, remove the phenomenon of cold mix in the wheat juice, prolong the quality time, improve the rate of receiving sugar and the washing achievement of the heater, increase each quantity of filtering beer, keep the beerí»s good flavor and foam, improve beerí»s stable.
Enzyme activity:ªG-dextranase 4000 iu/g;xylanase 3500 iu/g;cellulose 1500 iu/g;neutral protease 45000 u/g;middle temperature ªß-amylase 1500u/g.

Using method
The best quantity of this enzyme to sugar the beer is 300-600g per ton .This beer enzyme complex is especially used in the process of sugar, which the main material consist of 10-40 percent of wheat.In the case of the high sugar and the high using propotion of chinese malt, the inicial using quantity of this enzyme is 400-600g per ton.The using quantity can be reduced when the result of sugaring is very good.
This beer enzyme complex can be mixed after the materials have been put into the sugar pan.You can directly put the enzyme into the sugar pan when you use them.
Ph range:valid ph:3.6-6.5, the best ph:5.5+-
Temperature range:suitable temperature:40-75 centi degree, the best:65 centi degree.

Using range
This product can be mainly used in the beer production

Product presentation:
Beer complex enzyme which is independently combined by our corporation consists of some kinds of excellent enzyme which is used in beer brewing industry, including Beta-amylase,Xylanase,Cellulose,Neutral protease, Middle-temperature Alpha-amylase,etc
Through many experiments and pilot plant test, the proportion of combination is very reasonable and efficient, and can exert their function of all kinds of enzyme preparation. It has been used expansively in beer brewery, which has obtained good result.

Specification:
One kg per bag(Aluminum foil bag) 20kg per barrel.
Beta-dextranase:5600 IU/g Xylanase:2600 IU/g Cellulose:2200 IU/g.
Neutral protease:35000 u/g Middle-temperature Alpha-amylase:1500 u/g.
98 percent can pass 80 meshed normal sieve.

Using methods:
Recommended amount of beer saccharification is 200-500 g per ton malt
This beer complex enzyme mainly used in the process of saccharification of material which contents 10-40 percent of malt. In the event of high-concentrated glycation and using numerous national malt, the best using amount is 300-600 g per ton malt(net weight). If the result of glycation is very good, you can properly reduce the using amount.
This enzyme can be added after material has been put into mesh copper. This enzyme can be directly put into mesh copper.

Using condition:
PH range: proper PH:3.6-6.5, the best PH:5.5.
Temperature: proper temperature:40-75 centi grade,the best:65 centi grade.

Using result:
It is mainly used in the process of saccharification of beer brewing to improve and raise result of glycation.
1. It can validly decompose Xylanase,Beta-dextranase,reduce viscosity of malt juice, increase malt juice and beer¡¯s filter efficiency and quality.
2. Improve receiving rate of malt juice.
3. Decompose protease, improve content of Alpha-amino nitrogen and dissolved nitrogen in malt juice.
4. Improve washing result of filter, boiling machine
5. Increase amount of filtering beer each time.
6 Avoid validly turbidness to improve beer non-biological stability.

Storage and transportation:
This product is a kind of active substance, which should be put on the cool, dry place, avoiding strong shine,heat,moisture.If can be well kept six months below 25 centi grade, one year below four cent grade.
