Refined sunflower oil is among the most extensively used vegetable oils in foodservice, food manufacturing, retail, and international trade. The light colour, neutral flavour, and suitability for frying and packaging make refined sunflower oil a popular choice for all types of food buyers and food producers.
When purchasing refined sunflower oil, importers and distributors should consider a variety of factors in addition to price. These include the refining process, product specifications, packaging, certifications, and the consistency of the product from batch to batch.
This guide will describe the production process for refined sunflower oil, the difference between refined and crude sunflower oil, the specifications for refined sunflower oil, and the factors that buyers should consider before placing an order for bulk refined sunflower oil.
What Is Refined Sunflower Oil?
Refined sunflower oil begins as crude sunflower oil that has been extracted from sunflower seeds. This crude oil contains a variety of elements that can negatively impact the quality and characteristics of the oil, such as waxes, pigments, moisture, odour, and more.
The refining process removes or reduces these elements to produce an oil that is light yellow in colour and features a mild flavour and odour.
Most refined sunflower oil is typically produced as RBD or RBDW oil. RBD oil stands for refined, bleached, and deodorised oil. RBDW oil has the additional step of winterising the oil to remove waxes.
A reputable supplier of RBD sunflower oil will provide the buyer with product specifications, analysis certificates, origin documentation, and food safety certifications prior to shipment.
How Refined Sunflower Oil Is Produced
Refining crude sunflower oil can involve several different processes, but most manufacturers use the following stages:
- Degumming the crude sunflower oil removes phospholipids, gums, and other water-soluble elements.
- Neutralising the oil removes free fatty acids from the oil. Alkali refining with sodium hydroxide converts the free fatty acids into soapstock, which can be separated from the oil.
- Bleaching the oil with activated bleaching earth removes pigments and other unwanted elements from the oil.
- Deodorising the oil involves passing steam through the oil at high temperatures under vacuum conditions. This removes odours and flavours that are not preferred in the oil.
- Winterising the oil removes the waxes from the oil that can cause cloudiness at lower temperatures.
Specifications for Refined Sunflower Oil
Refined sunflower oil from the manufacturer will have the following specifications:
| Quality Parameter | Specification |
|---|---|
| Free Fatty Acids | 0.1% Maximum |
| Moisture and Volatile Matter | 0.1% Maximum |
| Insoluble Impurities | 0.05% Maximum |
| Peroxide Value | 5 meq O₂/kg Maximum |
| Colour | Light Yellow and Clear |
| Odour and Taste | Neutral and Characteristic |
| Iodine Value | 118–141 Approximately |
| Appearance | Clear, No Sediment |
These specifications can vary depending on the manufacturer and the destination market for the product. When placing a bulk order for refined sunflower oil, buyers should confirm these specifications with the supplier.
An independent inspection company can also be used to verify the quantity and quality of the sunflower oil prior to shipment.
Refined Sunflower Oil vs Crude Sunflower Oil
Refined and crude sunflower oil have different properties and different uses.
Refined sunflower oil is used in cooking and food processing industries. It is the type of sunflower oil that is used by manufacturers, caterers, distributors, wholesalers, and private label food brands.
Crude sunflower oil has not yet undergone the refining process. It is used in industries that require crude sunflower oil, such as refineries, food processing plants, feed manufacturers, and companies with their own refinery operations.
When purchasing crude sunflower oil, the supplier should state whether the oil is pressed or extracted, degummed or non-degummed, filtered or unfiltered, and whether it is intended for shipment or further refining.
What Is Unrefined Sunflower Oil?
Unrefined sunflower oil is minimally processed to retain as many of the natural features of the oil as possible. The oil is usually produced using cold pressing or expeller pressing methods.
Unrefined sunflower oil is typically used in speciality food products. It is used in salad dressings and other natural food products.
Buyers interested in purchasing unrefined sunflower oil wholesale should consider the following features of the oil:
- Processing method
- Quality of the sunflower seeds used
- Level of filtration
- Free fatty acid content
- Moisture content
- How to store the oil
- How long the oil will last
- How the oil will be used in food products
- Whether the oil is certified as organic or non-GMO
Due to the minimal processing of unrefined sunflower oil, the oil is more sensitive to heat and light and will begin to oxidize more quickly than fully refined sunflower oil.
Why Buyers Choose Refined Sunflower Oil
Refined sunflower oil is popular with buyers for several reasons.
Neutral taste and smell
Due to the deodorizing process, refined sunflower oil does not have a strong taste or smell.
Can be used with high temperatures
Refined sunflower oil is perfect for use in frying, sautéing, baking, and other high-temperature processes in the food industry.
Clear appearance
Refined and winterized sunflower oil has a clear and bright appearance.
Can be used in many food products
Refined sunflower oil is used in the following products:
- Restaurants and caterers

Flexible packaging options
Refined sunflower oil can be purchased in consumer packaging, industrial packaging, and bulk transport systems.
Refined Sunflower Oil Bulk Packaging Options
The packaging option that will best suit each buyer will depend on the distribution model, storage facilities, quantity purchased, and final use of the oil.
Flexitanks
Flexitanks are commonly used in 20-foot shipping containers to transport edible oils.
They will work best for buyers who have the equipment to handle and store the oil.
ISO tanks
ISO tanks, which are reusable containers for the transportation of bulk liquids, are another option for buyers who have industrial supply contracts and need to handle the oil.
Tanker vessels
Buyers who purchase vast quantities of sunflower oil may have it shipped to them using tanker vessels.
Intermediate bulk containers (IBC containers)
IBC containers are another option for buyers who need industrial quantities of oil but cannot receive a shipment of flexitanks or tanker vessels.
Drums
Food-grade drums are another option for select industrial orders.
Buyers will need to confirm the material of the drums, the internal coating, the net weight of the drums, and the pallet configurations of the drums.
PET bottles
Refined sunflower oil can also be packaged in the following PET bottles for retail and food service packaging:
- 1-litre bottles
- 2-litre bottles
- 3-litre bottles
- 5-litre bottles
- Custom private-label bottles
Each packaging option will require the negotiation and agreement of the packaging carton configuration, bottle design, caps, labels, barcodes, and palletisation.
What to Check When Choosing a Refined Sunflower Oil Supplier
Choosing a supplier based on the lowest price can be risky for buyers.
A good refined sunflower oil supplier will provide the following information to the buyer:
Product specifications
The supplier will provide a specification sheet that lists the product’s free fatty acid content, moisture content, impurities, peroxide value, colour, appearance, taste, and other agreed-upon characteristics.
Certificate of analysis
The supplier will also provide a certificate of analysis for the batch of oil supplied.

Variations in the oil’s colour, taste, free fatty acid content, moisture content, or peroxide value can affect the manufacturing process and the quality of the food products produced.
Food manufacturers should request product specifications from the supplier and arrange for testing of the oil before committing to a long-term supply contract.
A good RBD sunflower oil supplier will be able discuss the production capacity of the oil, the monthly availability of the oil, shipping lead times, how to trace the batches of oil, and how to plan for unforeseen circumstances in the supply of the oil.
Buying Crude Sunflower Oil for Further Refining
Refineries will need to consider different factors than those that are considered by bottled sunflower oil distributors.
The following factors should be considered when purchasing crude sunflower oil:
- Free fatty acid content
- Phosphorus content
- Wax content
- Moisture and impurities
- Peroxide value
- Flash point
- Fatty acid profile
- Sediment content
- Extraction method
- Refining loss
