COMMISSION RECOMMENDATION

of 2 March 2010

on the prevention and reduction of ethyl carbamate contamination in stone fruit spirits and stone fruit marc spirits and on the monitoring of ethyl carbamate levels in these beverages

(Text with EEA relevance)

(2010/133/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 292 thereof

Whereas,

| (1) | The Scientific Panel on Contaminants in the Food Chain of the European Food Safety Authority (EFSA) adopted on 20 September 2007 a scientific opinion on ethyl carbamate and hydrocyanic acid in food and beverages (1). In this opinion the Panel derived margins of exposure (MOE) for ethyl carbamate for different scenarios of food and beverage consumption. Based on these MOE the Panel concluded that ethyl carbamate in alcoholic beverages indicates a health concern, particularly with respect to stone fruit brandies, and recommended taking mitigation measures to reduce the levels of ethyl carbamate in these beverages. As hydrocyanic acid is an important precursor of ethyl carbamate formation in stone fruit spirits and stone fruit marc spirits, the Panel concluded that such measures should include focus on hydrocyanic acid and other precursors of ethyl carbamate, to prevent the formation of ethyl carbamate during the shelf-life of these products. |

ANNEX

Code of Practice for the prevention and reduction of ethyl carbamate contamination in stone fruit spirits and stone fruit marc spirits

INTRODUCTION

| 1. | Ethyl carbamate is a compound that occurs naturally in fermented foods and alcoholic beverages such as bread, yoghurt, soy sauce, wine, beer, and particularly in stone fruit spirits and stone fruit marc spirits, mainly those made from cherries, plums, mirabelles and apricots. |
| --- | --- |

1.

| 2. | Ethyl carbamate can be formed from various substances inherent in food and beverages, including hydrogen cyanide (or hydrocyanic acid), urea, citrulline, and other N-carbamyl compounds. Cyanate is probably the ultimate precursor in most cases, reacting with ethanol to form ethyl carbamate. |
| --- | --- |

2.

| 3. | In stone fruit distillates (stone fruit spirits and stone fruit marc spirits) ethyl carbamate can be formed from cyanogenic glycosides that are natural constituents of the stones. When mashing the fruit, the stones may be broken and cyanogenic glycosides from the stones may come into contact with enzymes in the fruit mash. Cyanogenic glycosides are then degraded to hydrocyanic acid/cyanides. Hydrocyanic acid may also be released from intact stones during a longer storage of the fermented mash. During the distillation process hydrocyanic acid may be enriched in all fractions. Under influence of light cyanide is oxidised to cyanate reacting with ethanol to form ethyl carbamate. Once the reaction has been triggered, it cannot be stopped. |
| --- | --- |

3.

| 4. | A major reduction in the concentration of ethyl carbamate could be achieved using two different approaches: first, by reducing the concentration of the main precursor substances; second, by reducing the tendency of these substances to react to form cyanate. The main influencing factors are the concentration of precursors (e.g. hydrocyanic acid and cyanides) and storage conditions, such as light exposure and temperature. |
| --- | --- |

4.

| 5. | Although no strong correlation between the level of hydrocyanic acid and ethyl carbamate has been established so far, it is evident that under certain conditions high concentrations of hydrocyanic acid lead to higher levels of ethyl carbamate. A potential increase in ethyl carbamate formation has been associated with levels at or above 1 mg/l hydrocyanic acid in the final distillate (1) (2). |

| --- | --- |

6.

I.   DESCRIPTION OF THE PRODUCTION PROCESS

| 7. | The production process for fruit spirits and fruit marc spirits involves mashing and fermentation of the whole fruit, followed by distillation. The process typically follows the steps listed below:






  — | crushing the whole ripe fruit; |
| --- | --- | --- |

7.

—

crushing the whole ripe fruit;

| — | fermenting the mash in stainless steel tanks or other suitable fermentation vessels; |
| --- | --- |

—

fermenting the mash in stainless steel tanks or other suitable fermentation vessels;

| — | transferring the fermented mash into the distillation device, often a copper pot; |
| --- | --- |

—

transferring the fermented mash into the distillation device, often a copper pot;

| — | heating the fermented mash by a suitable heating method in order to slowly boil off the alcohol; |
| --- | --- |

—

heating the fermented mash by a suitable heating method in order to slowly boil off the alcohol;

| — | cooling the alcohol vapour in an appropriate (e.g. stainless steel) column where it condenses and is collected; |
| --- | --- |

—

cooling the alcohol vapour in an appropriate (e.g. stainless steel) column where it condenses and is collected;

| — | separation of three different fractions of alcohol: ‘heads’, ‘hearts’ and ‘tails’; |
| --- | --- |

—

separation of three different fractions of alcohol: ‘heads’, ‘hearts’ and ‘tails’;

| 8. | During distillation, the heads boil off first. They can usually be recognised by their solvent or lacquer aromas. This fraction is generally unsuitable for consumption and should be discarded. |
| --- | --- |

8.

| 9. | During the middle distillation run (the ‘hearts’), the principal alcohol in all spirits, ethyl alcohol (ethanol), is distilled. This part of the distilling run, where the content of volatiles other than ethanol is lowest and the purest fruit aromas are found, is always collected. |
| --- | --- |

9.

| 10. | The ‘tails’ of the distillation include acetic acid and fusel oils, which are often identified by unpleasant vinegary and vegetal aromas. They are also discarded, but they may be re-distilled because some ethanol is invariably included with the tails. |
| --- | --- |

10.

II.   RECOMMENDED PRACTICES BASED ON GOOD MANUFACTURING PRACTICES (GMP)

Raw materials and preparation of fruit mash

| 11. | The raw materials and preparation of the fruit mash should be suitable to avoid the release of hydrocyanic acid. |
| --- | --- |

11.

| 12. | The stone fruits should be of high quality, not mechanically damaged and not microbiologically spoiled. |
| --- | --- |

12.

| 13. | The fruit should preferably be de-stoned. |
| --- | --- |

13.

| 14. | If the fruits are not de-stoned, they should be mashed gently to avoid crushing the stones. |
| --- | --- |

14.

Fermentation

| 15. | Selected yeast strains for alcohol production should be added to the mashed fruits, according to the instructions for users. |
| --- | --- |

15.

| 16. | Mashed fermented fruits should be handled with high standards of hygiene, and exposure to light should be minimised. The fermented fruit mash should be stored as short as possible before distillation since hydrocyanic acid may also be released from intact stones during longer storage of the mash. |
| --- | --- |

16.

Distillation equipment

| 17. | Distillation equipment and the distillation process should be suitable, to ensure that hydrocyanic acid is not transferred into the distillate. |
| --- | --- |

17.

| 18. | The distillation equipment should include automatic rinsing devices and copper catalytic converters. The automatic rinsing devices will keep the stills cleaned while the copper catalytic converters will bind hydrocyanic acid before it passes into the distillate. |
| --- | --- |

18.

| 19. | Automatic rinsing devices are not necessary in the case of discontinuous distillation. The distillation equipment should be cleaned by systematic and thorough cleaning procedures. |
| --- | --- |

19.

| 20. | In certain cases, when no copper catalytic converters or other dedicated cyanide separators are used, copper agents should be added to the fermented fruit mash before distillation. The purpose of the copper agents is to bind hydrocyanic acid. Copper agents are sold at specialised shops and should be used very carefully according to the manufacturer’s instructions. |
| --- | --- |

20.

Distillation process

| 21. | Stones settled in the fermented mash should not be pumped into the distillation device. |
| --- | --- |

21.

| 22. | Distillation should be carried out in such a way that alcohol is boiled off slowly (e.g. by using steam instead of a direct flame as the heating source). |
| --- | --- |

22.

| 23. | The first fractions of the distillate, called ‘heads’, should be separated carefully. |
| --- | --- |

23.

| 24. | The middle fraction, called ‘hearts’, should then be collected and should be stored in the dark. When the alcohol content reaches 50 % vol. in the receiver, collection should be switched to the ‘tails’, so that any ethyl carbamate that may have been formed is separated in the tail fraction. |
| --- | --- |

24.

| 25. | The separated tails, possibly containing ethyl carbamate, should be collected and if they are used for re-distilling, they should be re-distilled separately. |
| --- | --- |

25.

Checks on the distillate, re-distillation and storage

Hydrocyanic acid

| 26. | The distillates should be regularly checked for their levels of hydrocyanic acid. The determination should be carried out by appropriate tests, either by kits for rapid testing of the hydrocyanic acid levels, or, alternatively, by a specialist laboratory. |
| --- | --- |

26.

| 27. | If the concentration of hydrocyanic acid in the distillate exceeds a level of 1 mg/l, re-distillation with catalytic converters or copper agents (cf. points 18 and 20) is recommended, where appropriate. |
| --- | --- |

27.

| 28. | Distillates with hydrocyanic acid levels close to 1 mg/l should ideally also be re-distilled or, where this is not possible, be stored in lightproof bottles or covering boxes with storage times as short as possible in order to avoid ethyl carbamate formation during storage. |
| --- | --- |

28.

Ethyl carbamate

| 29. | Testing of ethyl carbamate is recommended for distillates in which the compound may already have been formed (e.g. distillates with unknown history of production, higher levels of cyanide, storage at light). The level of ethyl carbamate can only be tested by a specialist laboratory. |
| --- | --- |

29.

| 30. | If the distillate shows an ethyl carbamate concentration exceeding the target level of 1 mg/l, the distillate should be re-distilled, where appropriate. |
