Sugazym boosts the quality of beet and cane sugar.
Sugazym simplifies processing of raw materials containing starch and dextran.
Sugazym reduces the viscosity of sugar juice and syrup.

The dextran problem
Dextrans are not natural components of sugar cane or beets. They are formed after the harvest from sucrose through irreversible microbial metabolic processes. If these macromolecular polysaccharides get into production processes, it means:
Viscous dextran threads between spreading fingers during a typical inspection of sugar syrup. To the right, syrup without dextran.
Crystals that are deformed by dextran can easily break in centrifuges (B) or form too small incidental crystals (C) that get lost in the process.

These technical consequences result directly

Filtration
Crystal form
Eff ects on production processes
Viscosity caused by dextran reduces filter performance.
At concentrations of high molecular weight [HMW] dextran there is a shift in crystal sizes to smaller crystals, which implicates sugar loss during centrifugation.

When high dextran content can be expected
Dextran is not part of the plant’s own metabolism,but instead is formed by microbial infection of sugar cane or beets by Leuconostoc mesenteroides.The main causes are:
High humidity and temperatures Burnt plants (sugar cane) Alternating freezing and thawing (beets) Extended transportation and storage periods Too many and too large cuts in plants
Challenges in production operations

By adding Sugazym DX L you can eliminate viscosity problems early on and prevent crystal malformation. We recommend using it in the raw juice tank or in the first juice, depending on the process.
The use of Sugazym HiTaA L in the liming prevents the problems that starch poses during downstream proces-sing. Alternatively, Sugazym MeTaA L can be added in the final evaporation step.

The starch problem
Starch blocks the fine filter pores in the decolourising step.
Starch presents immense challenges in the sugar production and refining process. It is one of the main products of photosynthesis and is stored by the sugar cane plant. In the production process, starch swells. In large quantities, it has negative effects on your manufacturing productivity:
Easily visible: agglomerated starch binds impurities (B) and takes them to filtration, where they cause blockages. A = Normal flocking, C = Clear syrup.
Flow
Pressure
Time
Relation between filter throughput and pressure. The blocked filter pores raise the pressure and reduce the flow rate.
When you can expect high starch contentSugar cane contains starch in all seasons! But the amount in the plant varies with the specific variety and the weather. Factors that favour starch are:
High-starch sugar cane varieties Harvest with young, green cane Dryness
