MVO specifications for refined vegetable and marine oils excluding olive oil

January 2012

The specifications for refined vegetable and marine oils excluding olive oil 2012 of the Product Board for Margarine, Fats and Oils (MVO) provide information on the quality and safety parameters of refined oils and fats to buyers of these oils and fats. They include:

• legal limits for contaminants in oils and fats
• limits in Codex Alimentarius standards
• MVO guaranteed values for quality and food safety parameters which are not legally regulated
• recommended methods of analysis for the parameters mentioned

These values apply unless otherwise agreed in additional documents between supplier and buyer.

1) This applies to hydrogenated refined fats and oils.


Pesticide residues
According to EC Regulation No. 396/2005, European Maximum Residue Limits (MRLs) for processed products like oils and fats should be derived from the European MRLs for raw agricultural products. Concentration or dilution caused by processing must be taken into account. European MRLs for raw agricultural products can be found in the EU MRL database.
The reference method of analysis is NEN-EN 1528-1/4. FEDIOL has a list with recommended labs approved for analysing pesticide residues in oils and fats.


Quality parameters for refined oils and fats at loading

Bacteriological specifications 2)	Legal limit	Codex limit	MVO guaranteed value	Reference Method of Analysis
Total plate count			max 1000/g	ISO 4833
Salmonella			absent in 25 g	ISO 6579
Yeasts			max 10/g	ISO 7954
Moulds			max 10/g	ISO 7954
Enterobacteriaceae			max 10/g	ISO 21528-2
E. coli			max 10/g	ISO 16649-2

2)  Refined oils are sterile and have a too low moisture content for bacteria to affect the quality of the oil. However, during loading of means of transport contamination can occur. Bacteriological specifications should assure refined oils to be loaded according to good practices. 

Other quality parameters	Legal limit	Limit of Codex Standard for named vegetable oils	MVO guaranteed value	Reference Method of Analysis
Soap remains		50 mg/kg  (0.005% m/m)	max 10 mg/kg (0.001% m/m)	NEN 6330
Free fatty acids		0.3% FFA  (0.6 mg/KOH/g oil)	max 0.1% FFA (0.2 mg/KOH/g oil)	ISO 660
Peroxide value		max 10 milli  equivalents O2/kg	max 1.0 milli equivalents O2/kg	ISO 3960

Mineral oils and thermal heating fluids
Strict legislation for the transport of refined oils and fats by sea and by land prevents the contamination of refined oils and fats with mineral oils.
There is no risk of contamination of refined oils with thermal heating fluids because European oils and fat producers only use steam heating. Refined (or semi refined) products from third countries are regularly checked on the presence of thermal heating fluids.
