Liquefaction, saccharification and debranching enzymes for rice syrup plants running broken rice, rice flour or rice starch. Wholesale and bulk supply by quote for manufacturers and resellers.
Request pricingRice syrup plants lose money in the same places: a slurry that stays thick after cooking, a saccharification that runs long, filters that block early, and DE or Brix that drifts from batch to batch. Most of that is decided by how the enzyme program fits the rice you actually receive, not by the enzyme name on the drum.
Enzymesvalue supplies the enzyme stack for rice syrup production: alpha-amylase for liquefaction, glucoamylase for saccharification and pullulanase for debranching. Amylase is used on starch outside food as well, and a German-language page covers desizing with fungal alpha-amylase in textiles. We work with syrup manufacturers, ingredient distributors and resellers who buy in bulk, and every order is quoted to the plant's process and volume.

Broken rice is a practical, lower-cost feedstock, but it does not behave like refined starch. Particle size, starch damage, protein load, fines, soaking history and seasonal changes in the rice all move slurry viscosity, liquefaction speed, saccharification time and filtration rate. One batch can liquefy cleanly and the next can hold viscosity far longer, which costs steam, agitator load and schedule time. A good enzyme plan is built around that variability: the plant knows which step to adjust when a new rice lot arrives, instead of correcting the syrup at the end.

The front end of a starch-sugar line is a thermostable alpha-amylase made for the liquefaction of starch raw materials. It is built to survive jet cooking: it keeps working in a jet liquefaction system at 110 °C. A typical liquefaction setup is a starch slurry at 25-35% dry solids and pH 5.4-5.8, jet-cooked at 105-110 °C and held for 5-10 min. The enzyme dose is set per tonne of dry starch, so the right figure for your plant depends on the solids you run and is confirmed in a trial. It works by rapidly cutting the main-chain bonds of the starch, which is what turns a heavy cooked slurry into a pumpable dextrin stream.
The second step is glucoamylase, which converts those dextrins into sugar. The same glucoamylase is used across starch sugar, brewing, seasonings, traditional malt syrup and dextrin production, so a rice syrup plant buys from the same product family as much larger starch-sugar users. Its working range is 30-65 °C and pH 3.5-6.0, which means the liquefied stream has to be cooled and its pH brought down before the glucoamylase goes in.
| Step | Enzyme | Working window | What goes wrong if it is off |
|---|---|---|---|
| Liquefaction | Thermostable alpha-amylase | 105-110 °C jet cooking, pH 5.4-5.8, slurry at 25-35% dry solids | Slurry stays thick, pumps and heat exchangers struggle |
| Saccharification | Glucoamylase | 30-65 °C, pH 3.5-6.0 | Hot or high-pH stream slows conversion and DE stalls |
| Debranching | Pullulanase, added with the glucoamylase | Matched to the saccharification step | Residual branched dextrins load the filters |
