Question 1

What is the best cooking oil for deep frying in a commercial kitchen?

Accepted Answer

For commercial deep frying, high-oleic sunflower oil or a high-oleic sunflower/canola blend offers the best balance of frying stability, cost, and clean flavour. High-oleic oil lasts 2–3x longer than standard sunflower before polar compounds reach the 25% legal food safety limit. Palm olein is also widely used for its natural stability and low cost, particularly in Asian and Middle Eastern cuisine styles. Avoid standard high-linoleic sunflower for continuous frying — it oxidises and breaks down relatively quickly.

Question 2

What packaging size is standard for restaurant cooking oil delivery?

Accepted Answer

The food service standard is 20-litre jerry cans (or cubitainers), which are easy for kitchen staff to handle and store. 5-litre bottles are used in smaller kitchens or for specialty oils. 200-litre drums are available for very high-volume operations (large hotels, central kitchens) but require a drum pump and appropriate storage. Some suppliers offer used cooking oil (UCO) collection in exchange for fresh oil delivery — useful for restaurants with sustainability commitments.

Question 3

How do I calculate how much cooking oil my restaurant uses per month?

Accepted Answer

A rule of thumb for busy restaurant fryers: a commercial fryer (15–20 litre basket capacity) uses approximately 2–4 litres of top-up oil per day in active frying service, with a full oil change every 3–7 days depending on oil type, fryer design, and what is being fried. For weekly ordering, track how many 20L cans you go through per fryer per week — most mid-size restaurant kitchens with 2–4 fryers use 80–160 litres of cooking oil per month.

Question 4

Can I get Halal-certified cooking oil for a restaurant serving Halal food?

Accepted Answer

Yes. Refined sunflower, palm olein, canola, and soybean oil are all inherently Halal-compatible, but you need a valid Halal certificate from a recognised certification body issued to the specific production facility. Ask your supplier for a current Halal certificate (not older than 1 year) from a body recognised in your market. For UK restaurants: HMC or IFANCA; for UAE/GCC: ESMA or SFDA; for Indonesia: MUI.
