Commission Regulation (EU) No 1272/2009 of 11 December 2009 laying down common detailed rules for the implementation of Council Regulation (EC) No 1234/2007 as regards buying-in and selling of agricultural products under public intervention (repealed) (c. 1272)

ANNEX I CEREALS

PART VIII Determination of the rate of loss of vitreous aspect

1. Principle

Only part of the sample is used to determine the percentage of grains which have wholly or partially lost their vitreous aspect. The grains are cut using a Pohl grain cutter or an equivalent instrument.

2. Equipment and apparatus

• Pohl grain cutter or equivalent instrument,

• tweezers, scalpel,

• tray or dish.

3. Procedure

(a)

The determination is carried out on a sample of 100 g after separation of any matter other than basic cereals of unimpaired quality.

(b)

Spread the sample on a tray and homogenise well.

(c)

Insert a plate in the grain cutter and spread a handful of grains on the grid. Tap firmly to ensure that there is only one grain in each hole. Lower the moveable section to hold the grains in place and then cut them.

(d)

Prepare sufficient plates to ensure that a minimum of 600 grains are cut.

(e)

Count the number of grains which have wholly or partially lost their vitreous aspect (mitadiné).

(f)

Calculate the percentage of grains which have wholly or partially lost their vitreous aspect (mitadiné).

4. Expression of results

I

=

mass, in grams, of matter other than basic cereals of unimpaired quality.

M

=

percentage of cleaned grains examined which have wholly or partially lost their vitreous aspect (mitadiné).

5. Result

The percentage of grains which have wholly or partially lost their vitreous aspect (mitadiné) in the test portion is:

(M × (100 - I))/100 = …
