Dextran from Frozen or Deteriorated Beet: Juice Viscosity and Filtration Control
When beet quality shifts, the process feels it quickly: diffusion becomes less predictable, raw juice viscosity rises, clarification behavior changes, and filtration load can move from manageable to restrictive within a campaign window.
Dextran is often behind it when the campaign runs into deteriorated beet, microbial activity, frozen/thawed beet, long storage, delayed slicing, or slow beet yard turnover. Enzymeschoice works with factory process teams, and with the distributors who supply them, to scope an enzyme treatment for that problem, matched to refinery operating conditions and procurement requirements.

Why dextran becomes a factory problem
Dextran is commonly associated with microbial activity on beet and in process streams. It can become more visible when beet are stressed, damaged, frost-affected, stored too long, or processed after deterioration has started.
In the factory, dextran is not only a laboratory concern. It can influence how juice moves, separates, filters, and concentrates.
Typical process signals include:
- Higher apparent viscosity in juice streams
- Slower or less consistent filtration
- More difficult clarification behavior
- Increased pressure across filter stations
- Reduced mud handling predictability
- Foam or flow irregularities in affected areas
- Less stable evaporation and crystallization conditions downstream
- Campaign variability tied to beet condition rather than equipment alone
Dextranase is used to break down dextran chains so the process can return toward more stable flow and separation behavior.
Where dextranase fits in beet sugar processing
Dextranase is typically considered when dextran is creating measurable operating drag. The practical objective is not to change the identity of the factory process, but to reduce the impact of dextran on viscosity and filtration behavior.
Potential application points are selected around plant layout, juice temperature profile, residence time, pH conditions, and where dextran is most disruptive. The right location depends on the factory: beet quality, diffusion system, liming and clarification sequence, filtration configuration, and campaign rhythm all matter.
Enzymeschoice supports buyer-side evaluation with questions process managers already track:
- Where does pressure rise first?
- Is filtration instability tied to specific beet deliveries?
- Does viscosity change after delayed slicing or freeze/thaw events?
- Are clarification and mud settling behaving differently than normal?
- Is downstream evaporation or crystallization becoming harder to control?
- Is the problem episodic, campaign-wide, or linked to storage conditions?
Supply for campaign conditions
Sugar beet factories do not need speculative language. They need dependable enzyme supply that fits campaign planning, procurement approval, and plant handling.
Enzymeschoice provides dextranase for bulk ordering with a focus on:
- Consistent lot-to-lot supply documentation
- Practical storage and handling guidance
- Quote-based procurement for factory demand
- Packaging discussions for plant dosing workflow
- Clear communication around lead time and availability
- Technical alignment with beet condition and process objectives
We do not position dextranase as a universal fix for all beet quality problems. It is a targeted processing aid for dextran-related viscosity and filtration challenges, and it should be evaluated against real factory indicators.
Operating value: control what dextran makes unstable
When dextran is present, the value of dextranase is measured in process behavior, not in a brochure claim. Buyers typically evaluate the effect through existing factory data and operator observations, including:
- Lower viscosity trend in affected streams
- Improved filterability and flow continuity
- More predictable pressure behavior
- Cleaner transitions through clarification and filtration
- Reduced disruption during poor beet intervals
- More stable downstream concentration and crystallization handling
- Better confidence when processing frost-damaged or delayed beet lots
The aim is controlled operation: fewer surprises, cleaner flow behavior, and a more predictable response when beet quality is uneven.
For deteriorated, frozen/thawed, or delayed beet
Dextran problems often appear when incoming beet have already begun to lose process quality. Common triggers include:
Deteriorated beet
Mechanical damage, warm storage, microbial loading, and delayed processing can create conditions where dextran becomes a serious process variable.
Frozen and thawed beet
Freeze/thaw events can weaken beet tissue and change microbial dynamics. Factories may see more variable diffusion, juice quality, and filtration behavior after thawed beet enter the line.
Delayed processing
When beet spend longer in storage or delivery queues, process teams may face a narrower operating window. Dextranase can be considered as part of a broader response to maintain flow and separation stability.
How Enzymeschoice approaches selection and quoting
To prepare a useful dextranase quote, Enzymeschoice typically asks for practical operating context rather than unnecessary complexity:
- Beet condition and campaign timing
- Suspected source of dextran concern
- Main process symptom: viscosity, filtration, pressure, clarification, or downstream instability
- Intended application area
- Estimated campaign volume or purchasing interval
- Preferred packaging and delivery timing
- Site handling constraints
- Delivery destination, and whether the material is for your own plant or for resale to sugar factories
From there, we can recommend an appropriate supply format and quote price, pack format and lead time for that order.
