Sugar beet molasses is a thick, brown syrup that is leftover after the manufacturing of sugar out of sugar beets. It contains significant amounts of fermentable sugars, protein, vitamins as well as minerals. The main applications of molassed sugar beet include:
Specifically, molasses is widely used as a nutrient-dense supplement in cattle and livestock feed rations. It also serves as an excellent source of sugars to produce baker's yeast, ethanol, citric acid and other products through large-scale fermentations. The sugars and micronutrients in molasses also make it suitable for certain niche food products.
·As an animal feed ingredient ·As fermentation feedstock for industrial microbiology processes ·As a sweetener for flavoring human foods ·As an agricultural fertilizer
The below table explains sugar beet molasses composition. At the time of getting fermented sugar beet molasses, it is worth to be aware of the characteristics and composition.

Molasses made from sugar beets are useful in a variety of industries. Here are some of the most prominent industries out of them.
Sugar beet molasses is commonly blended into rations and feed as a source of readily available energy and minerals for livestock. The sugars are easily fermented in the rumen to volatile fatty acids that are absorbed and utilized. Molasses enhances palatability and benefits pellet production. Typical inclusion rates are 2-8% of the total mixed ration for cattle, delivering carbohydrates, protein, potassium, sulfur and B-vitamins. It is an economical feed ingredient.
Animal Feed Production
The sugars in beet molasses provide an optimal feedstock for culturing yeasts. Molasses supports yeast growth and fermentation without the need for expensive media. It is used to produce baker’s yeast, along with yeast extracts and supplements. Molasses is pasteurized, fermented, and processed to harvest yeast and valuable byproducts.
Production of Yeast
It is also a great feedstock for anaerobic digestion to produce biogas and biomethane. Its sugars are readily converted to methane and carbon dioxide. Blending with other substrates creates a balanced feedstock. Molasses boosts biogas yields. The process produces renewable natural gas and a biofertilizer digestate.
Production of Biogas/Biomethane
Beet molasses provides a cost-effective, renewable feedstock for ethanol production via yeast fermentation. As an alternative to food crops like corn, molasses does not compete with human food supplies. With proper nutrient supplementation, nearly 50% of the sugar content can be converted to fuel-grade ethanol for blending with gasoline.
Production of Ethanol
Molasses is commonly used to produce citric acid, an important industrial acid with applications in foods, pharmaceuticals, and cleaning agents. The sugars support high-yielding fermentation by the mold Aspergillus Niger to metabolize and excrete citric acid. Molasses provides an economical substrate relative to other carbohydrate sources.
Production of Citric Acid
Proper storage and transportation practices are critical for maintaining the quality and utilization of sugar beet molasses.
Steps for Storage of Sugar Beet Molasses.
To prevent excessive microbial fermentation and decomposition during warm seasons, molasses must be stored in temperature-controlled, insulated stainless steel tanks during warehouse storage and transit. Tanks should be heated to maintain the product above 110°F during storage to keep the viscous molasses pumpable for transport and downstream processing. Temperatures should also not exceed 160°F to avoid detrimental heat effects. Care should be taken that tank insulation and heating capacity are adequate to limit temperature fluctuations.
Bulk shipment in dedicated tanker railcars or tanker trucks is common, ranging from 25-200 tons per container. Heating and insulation capacity should allow the molasses to remain between 110-150°F in transit. Railcars and tanker trucks should have food-grade, corrosion-resistant stainless steel tanks to prevent corrosion and off-flavors.
Cleaning and sanitation of transport containers is critical to avoid contamination across loads. Molasses should be gently agitated before unloading to ease pumping. Then you can learn more on how to make molasses from sugar beets. This is applicable for both fermented sugar beet molasses and desugared sugar beet molasses.
With proper temperature-controlled storage in food-grade tanks, sugar beet molasses can remain stable for up to 6 months post-production. Careful temperature and tanks management preserves quality for industrial use.
