In pasaraninternasional corn starch used

In pasaraninternasional corn starch used as a substitute material for the manufacture tepungterigu biscuits, noodles, high-fructose syrup, industrial adhesives, and pharmaceutical industries. Utilization and value tambahsagu at the farm level is still vBOLAWIN88.COM PUSAT BANDAR TARUHAN AGEN JUDI BOLA CASINO POKER BOLATANGKAS DAN TOGEL ONLINE TERPERCAYA INDONESIAery simple. This karenasebagian sago processing purposes only to meet kebutuhankeluarga. The simple way of generating a low yield dankurang efficient.
Sago contains carbohydrates, protein, fat, calcium, and iron are high. With these contents, sago potentially be used as raw material dapatmeningkatkan glucose syrup added value sago. Sago starch containing 27% amylose dan73% amylopectin. Comparison of the composition of amylose content and starch properties amilopektinakan influence. The higher the amylose content patibersifat less dry, less sticky and easier to absorb water (hygroscopic).
Sago starch granules which have elliptical agakterpotong with granule size of 20-60  m and ranges from 60-72oC suhugelatinisasinya. Meanwhile, according to Wirakartakusumah et al., (1986) Starch gelatinization temperatures around 72-90oC.
A. Starch Hydrolysis
As bioethanol feedstock, sago starch will be hydrolyzed untukmendapatkan glucose, then fermented for mendapatkanbioetanol. Sago starch hydrolysis will produce a viscous liquid starch hydrolysates yangmerupakan the main component of glucose. Hidrolisispati into glucose can be done with the help of acid or enzimpada time, temperature and pH specific. Various ways of starch hydrolysis telahbanyak developed among which acid hydrolysis, acid hydrolysis and enzyme combination enzimdan.
Asammemiliki starch hydrolysis process diagram using a simple, but requires a complicated persyaratanperalatan (heat-resistant, high pressure). Denganhidrolisis different enzymatic, in addition to processing conditions are not extreme, the use of enzymes to produce the yield and quality of solution glukosayang higher than acid hydrolysis. In hidrolisissecara enzymatic starch ties cut according to the type of enzyme which is used, whereas when using acid dilakukansecara random cuts.vcc.co.id provider vcc murah di indonesia  
At sago starch hydrolysis process to convert starch tahapandalam there are three stages namely gelatinization, liquefaction dansakarifikasi. Gelatinization stage is the formation of starch granules kentaldari suspension, ie liquefaction stage hydrolysis process patiparsial characterized by decreasing viscosity and sakarifikasiyaitu further process of hydrolysis to produce glucose.
At this stage of liquefaction occurred -1,4 glycosidic bond breaking olehenzim  -amylase on the inside of the polysaccharide chains are generated acaksehingga glucose, maltose, maltodextrin and -limitdekstrin. Enzymes. -amylase is an enzyme that hydrolyzes secarakhas through the inside of the oligosaccharide producing alpha darikonfigurasi severing ties  - (1,4) glycosidic on amylose, amylopectin, and glycogen. Association of  - (1,6) glycosidic not dapatdiputus by -amylase, but it can be made into short branches yanglebih (Nikolov and Reilly, 1991). -amylase enzyme from Bacillus amyloquefaciens umumnyadiisolasi, B. licheniformis, Aspergillusoryzae, and A. niger. The optimum pH for this enzyme is about 6 to suhuoptimum 60oC. If the temperature is further increased the pH optimum punsemakin increased to about seven.
In likuifikasi patibiasanya -amylase used is one that has aktivitastinggi, so the enzyme dosage used approximately 0.5-0.6 kg / ton patiatau 1500 U / kg of dry substrate. -amylase enzyme commercially made ​​olehNovo Industri A / S, among others, by the name of the memilikiketahanan Termamyl the ambient temperature of 95-110oC. Termamyltergantung stability at temperature, the concentration of Ca2 + ion content and ekIndotophosting.com Hosting Unlimited dan Domain Murah Terbaik di Indonesiauivalendekstrosa. -amylase dose commonly used between 0.5 to 0.6kg Termamyl 102 L per tonne of dry starch. The KNU (kilo Novo-amilaseUnit ) is the amount of enzyme that can hydrolyze starch 5.26 (gramstandar) per hour at 37 ° C, pH 5.6 at standard conditions.
