Overview
Sugarcane molasses is a thick, dark syrup derived from the sugar refining process. It retains residual sugars and nutrients after sucrose crystallization. As a cost-effective feedstock, it is globally traded for industrial and agricultural uses. Its composition varies slightly depending on sugarcane origin and processing methods, but it consistently offers high energy density and fermentable carbohydrates. The product is classified as food-grade or technical-grade based on purity.
Physical and Chemical Properties
Sugarcane molasses is hygroscopic and highly viscous, with a characteristic caramel-like odor. Its high sugar content (primarily sucrose, glucose, and fructose) makes it an excellent carbon source for microbial fermentation. The liquid also contains minerals like potassium, calcium, and iron, contributing to its nutritional value in animal feed. Its density and viscosity require heated storage tanks in cold climates to facilitate pumping and handling.
Main Applications
In fermentation industries, molasses serves as a substrate for producing ethanol, citric acid, and yeast. Its affordability and sugar concentration make it preferable to refined sugars for large-scale bioprocessing. Agriculture relies on molasses as a palatability enhancer and energy supplement in livestock feed. Additionally, it is used in baking, brewing, and as a binder in fertilizer pellets. Emerging applications include bio-based chemical synthesis.
Safety and Storage
While non-hazardous, molasses can attract pests due to its sugar content. Sealed containers and clean storage areas are essential to prevent contamination. Spills should be promptly cleaned to avoid slippery surfaces. Bulk storage tanks should be corrosion-resistant (e.g., stainless steel) and equipped with heating coils in temperate regions to maintain flowability. Food-grade molasses requires compliance with FDA or equivalent regulations.
B2B Procurement Guide
Buyers should specify parameters like Brix (sugar concentration), ash content, and microbiological limits. Food-grade purchases necessitate certificates of analysis (CoA) for heavy metals and pesticides. Suppliers often offer molasses in tanker trucks, drums, or totes. Long-term contracts are common due to seasonal production. Prices fluctuate with sugar market trends and regional availability, with bulk discounts typically applied for orders exceeding 20 metric tons.
