Quality Control
From the fields to the bottle, quality is checked at every step of our production process.
Quality Constantly Checked
At Sule Manufacturers Ltd, quality is not a final step, it is embedded in every stage of our production process. We are a team of experts committed to the highest quality standards, and we maintain oversight from the fields all the way through to the moment sunflower oil is carefully filled into each bottle.
All our products are produced under UNBS (Uganda National Bureau of Standards) parameters and supervision, ensuring that every batch meets Uganda's national food safety and quality benchmarks.
"We are a team of experts, and we commit ourselves to the highest quality standards."
Four Stages of Quality Control
We inspect quality at every critical stage, from raw material intake to finished product packaging.
1. Seed Inspection
All sunflower and soya seeds are sourced from our vetted farmer network and inspected on arrival. We check moisture content, purity, foreign matter, and absence of aflatoxins before any seed enters our mill.
2. Oil Extraction
During the pressing and extraction process, oil samples are tested for free fatty acid content, peroxide value, and colour, ensuring the crude oil meets our strict input quality standards before refining begins.
3. Refining & Processing
During degumming, neutralisation, bleaching, and deodorisation, quality parameters are continuously monitored. Only oil that meets UNBS specifications for colour, taste, odour, and fatty acid profile proceeds to packaging.
4. Packaging & Final Check
Before leaving our facility, every batch undergoes a final inspection, including fill accuracy, seal integrity, label correctness, and a physical quality check against UNBS benchmark samples.
