20 TPD Peanut Oil Processing Plant in Ghana
Full-refinery groundnut oil line for Greater Accra food company — roasting, pressing, degumming, neutralizing, bleaching, and deodorizing — producing batch-consistent colour oil now sold as "Premium Ghana Groundnut Oil" in Shoprite and Melcom.
Project Overview
Ghana is West Africa's second-largest peanut producer, growing over 500,000 tonnes annually across the Northern, Upper East, and Brong-Ahafo regions. A Greater Accra food company — already producing peanut butter and snack products — had been purchasing all of its refined groundnut oil requirements from importers at substantial cost.
The company's vision was vertical integration and a new retail brand: "Premium Ghana Groundnut Oil" that could compete on the combined appeal of local provenance and consistent quality in a market where imported brands dominated the transparent-bottle premium segment. This required full refinery capability — not just pressing and basic degumming.
The critical retail requirement was batch-to-batch colour consistency. A transparent PET bottle on a supermarket shelf immediately reveals colour variation — and inconsistent colour signals poor quality to Ghanaian consumers. This meant the full refinery sequence was non-negotiable: degumming, neutralizing, washing, bleaching (to standardize colour), deodorizing, and 5-micron polishing filtration.
The peanut oil is hot-pressed (roasting at 180°C) to develop the characteristic nutty aroma that Ghanaian and West African consumers associate with authentic groundnut oil. The deodorizer is operated at moderate intensity to remove harsh off-notes while preserving the desired roasted peanut character — a deliberate process design choice, not the neutral deodorization used for food manufacturing applications.
The PLC-controlled process ensures consistent batch quality. After 18 months of commercial operation, the company has received zero quality complaints from retail buyers — and has expanded distribution from the original 8 outlets to 40+ independent shops plus Shoprite and Melcom chain listings.

Results
Key performance metrics after 18 months of commercial operation at the Accra plant.
"Our 'Premium Ghana Groundnut Oil' brand has been very well received in Accra. Consumers are proud to buy locally processed oil. The colour consistency the refinery gives us was what we needed for a premium retail product — you cannot have variable colour in a transparent bottle on a supermarket shelf. We have been running 18 months with no quality complaints."— Production Director, food company, Accra, Ghana | January 2024

Expert answers on Ghana FDA standards, West African groundnut oil markets, and food safety in peanut processing.
What standards apply to edible groundnut oil in Ghana?
Ghana Food and Drugs Authority (FDA) standards for edible groundnut oil include: FFA (as oleic acid) ≤0.5%, moisture ≤0.1%, iodine value 82–107 g I₂/100g, peroxide value ≤10 meq/kg, saponification value 185–200. The oil must meet Ghana Standards Authority (GSA) GS 248 for edible vegetable oils. Our Accra plant produces oil at FFA under 0.2%, comfortably within standards. Aflatoxin testing of incoming peanuts is critical — high contamination is common in poorly stored Ghanaian groundnuts.
Why is groundnut oil popular in West Africa?
Groundnut oil has been a staple cooking oil in West Africa for centuries. Its high smoke point (230°C refined, 160°C crude), neutral to nutty flavour, and compatibility with regional cuisines make it preferred for frying, sautéing, and marinades. In Ghana, Nigeria, Senegal, and neighboring countries, groundnut oil has cultural significance in traditional dishes (groundnut soup, jollof rice, kelewele). The strong local consumption creates a reliable domestic market for groundnut oil producers.
How do I prevent aflatoxin contamination in peanut oil production?
Aflatoxin (produced by Aspergillus flavus/parasiticus fungi) is a critical food safety concern for peanut oil. Key control measures: (1) Reject visibly mouldy, shrivelled, or discoloured peanuts at intake, (2) Ensure incoming peanut moisture under 10% to prevent mould growth in storage, (3) Rapid first-in-first-out turnover of peanut stocks, (4) Maintain storage humidity under 70%, (5) Test incoming peanut batches with aflatoxin rapid test kits or HPLC, (6) Note: aflatoxins are not destroyed by roasting at normal temperatures. A refinery including bleaching earth step does partially reduce aflatoxin levels.
Can I sell groundnut oil pressed from Ghanaian peanuts in Europe?
Yes, with significant compliance requirements. EU aflatoxin limits for groundnut oil are B1 ≤2 μg/kg, total ≤4 μg/kg (extremely low). This requires strict incoming peanut testing and rejection protocols. EU food business operators must register with competent authorities, implement HACCP, and meet traceability requirements (EU 178/2002). Some EU member states require additional testing. Our approach for EU-targeting plants includes full HACCP implementation support and aflatoxin management protocols.
What is the shelf life of refined groundnut oil?
Properly refined and packaged groundnut oil (sealed in PET or glass, nitrogen-flushed, dark storage) has a shelf life of 18–24 months. Key factors affecting shelf life: peroxide value at packing (under 1 meq/kg ideal), degree of deodorization (removes peroxides), packaging integrity, storage temperature (under 25°C), and light exposure. Natural antioxidants (tocopherols) are partially preserved through physical refining. Some producers add synthetic antioxidants (BHA, BHT) to extend shelf life — check local food additive regulations.
