Quality Control
& Assurance
From sugarcane field to shipping container, every step of our production process is governed by strict quality control protocols that meet international food safety and export standards.
Our Philosophy
Quality Is Not an Afterthought — It Is Our Foundation
At Kanthararom Sugar, quality assurance is embedded into every stage of our operation. We do not simply test the final product — we control and monitor quality at each critical point from raw material intake through to the sealed export container.
Our integrated quality management system combines ISO 9001 process discipline, ISO 22000 food safety management, HACCP hazard analysis, and GMP manufacturing hygiene into a single, cohesive framework. This ensures that every ton of sugar leaving our facility meets both our internal standards and the exacting requirements of international buyers.
Quality at a Glance
Comprehensive Controls
8 Critical Quality Control Areas
Each area of our quality control program is designed to verify, measure, and document compliance with international standards at every stage of production and export.
Precision at Every Level
Advanced instrumentation ensures every batch meets exact specifications before export.
Sugarcane Quality Inspection
15,000+ farms inspected annually
Every delivery of sugarcane is inspected at the mill gate before processing begins. Our agronomists assess cane freshness, Brix levels, fiber content, and trash percentage using calibrated refractometers and sampling protocols. Only cane meeting our strict quality thresholds enters the production line, ensuring high sucrose recovery and consistent product quality from the very first step.
ICUMSA Testing
ICUMSA 45 tested every 30 min
ICUMSA (International Commission for Uniform Methods of Sugar Analysis) color measurement is the global benchmark for sugar quality grading. Our laboratory performs ICUMSA testing on every production batch using spectrophotometric analysis at 420nm. Refined white sugar is verified to meet ICUMSA 45 standards (maximum 45 RBU), while other grades are tested against their specific ICUMSA targets to guarantee compliance with international trading specifications.
Moisture Analysis
Max 0.04% moisture on refined
Moisture content is a critical quality parameter that directly affects sugar shelf life, free-flowing properties, and compliance with export specifications. We employ both inline NIR (Near-Infrared) sensors on the production line and laboratory oven-drying methods for verification. Refined white sugar is held to a maximum of 0.04% moisture, while raw sugar must not exceed 0.5%. Continuous monitoring ensures every batch meets the tight tolerances required by international buyers.
Crystal Size Control
0.4-0.7mm refined grain target
Uniform crystal size is essential for consistent dissolution rates, appealing visual presentation, and meeting buyer specifications. Our vacuum pan operators use automated vision systems and sieve analysis to monitor crystal growth in real time during the crystallization process. Finished sugar undergoes particle size distribution testing using standardized mesh screens. Refined white sugar targets 0.4-0.7mm grain size, while raw sugar is controlled to 0.9-1.2mm, ensuring every shipment meets the exact granulometry required.
Contaminant Removal
Zero-tolerance foreign material
Food safety demands absolute vigilance against physical, chemical, and biological contaminants. Our multi-stage contaminant removal system includes magnetic separators for ferrous metals, gravity separators for stones and heavy particles, multi-stage filtration for juice and syrup clarification, and activated carbon treatment during refining. Every packaging line is equipped with inline metal detectors and X-ray inspection systems that reject any package containing foreign materials, guaranteeing the purity of our final product.
Laboratory Testing
COA with every shipment
Our in-house laboratory is equipped with advanced analytical instruments and staffed by qualified food scientists who perform comprehensive testing on every production batch. Tests include polarization (Pol) for sucrose purity, reducing sugars, ash content (conductivity method), SO2 residual levels, microbiological analysis (total plate count, yeast, mold, coliforms, and E. coli), and heavy metals screening. A Certificate of Analysis (COA) accompanies every shipment, providing full traceability and analytical verification.
Packaging Inspection
Weight tolerance +/- 0.1%
Packaging integrity protects product quality throughout the entire supply chain. Our inspection protocols verify bag weight accuracy using high-precision checkweighers (tolerance of plus or minus 0.1%), seal strength through burst testing, print quality for batch codes and branding, and packaging material food-grade certification. Every bag passes through inline metal detectors before palletization. Random samples from each production run undergo accelerated shelf-life testing to confirm that packaging maintains product quality under real-world storage conditions.
Pre-shipment Inspection
100% SGS verified
Before any container leaves our facility, a comprehensive pre-shipment inspection is conducted. Independent SGS inspectors verify product quality, weight, packaging condition, and container cleanliness. Container structural integrity is checked and documented with photographs. Fumigation is performed and certified where destination regulations require it. All export documentation — including Bills of Lading, Certificates of Origin, phytosanitary certificates, health certificates, and SGS inspection reports — is compiled and verified for accuracy before shipment release.
