DETECTION OF ANTIMICROBIAL RESIDUES IN SKIMMED MILK POWDER
UGOTAVLJANJE ANTIMIKROBNIH OSTANKOV V POSNETEM MLEKU V PRAHU
A microbial inhibitor screening test using Geobacillus stearothermophilus var. calidolactis ATCC 10149 (identical to strain C953) as test micro-organism and being sufficiently sensitive to detect 4 μg benzylpenicillin per kg milk and 100 μg sulfadimidine per kg milk shall be used.
Uporablja se mikrobni inhibitorski izločilni preskus z Geobacillus stearothermophilus var. calidolactis ATCC 10149 (enak kot C953) kot preskusnim mikroorganizmom, ker je dovolj občutljiv, da zazna 4 μg benzilpenicilina v kilogramu mleka in 100 μg sulfadimina v kilogramu mleka.
Commercial tests kits are available and can be used if they have the required sensitivity for benzylpencillin and sulfadimidine.
Na voljo so komercialni kompleti za preskušanje in se lahko uporabijo, če imajo zahtevano občutljivost za benzilpenicilin in sulfadimin.
For the test, reconstituted skimmed milk powder (1 g powder +9 ml aqua dest) is used.
Za preskus se uporabi rekonstituirano posneto mleko v prahu (1 g prahu +9 ml destilirane vode).
The test is carried out as described in ISO/TS 26844:2006 Milk and milk products — Determination of antimicrobial residues — Tube diffusion test IDF — Bulletin No 258/1991, section 1, Chapter 2, or according to the instructions of the test kit manufacturer [1].
Preskus se izvede, kakor je opisano v standardu ISO/TS 26844:2006, mleko in mlečni proizvodi – ugotavljanje antimikrobnih ostankov – difuzijski test epruvete IDF, Bilten št. 258/1991, oddelek 1, poglavje 2, ali v skladu z navodili proizvajalca preskusnega kompleta [1].
Positive results are to be interpreted as follows:
Pozitivni rezultati naj se interpretirajo tako:
The presence of β-lactams can be confirmed by repeating the test adding penicillinase to the test system [2]:
Prisotnost β-laktamov lahko potrdite s ponovitvijo preskusa z dodatkom penicilinaze preskusnemu sistemu [2]:
Negative result: Inhibiting substance is a β-lactam antibiotic.
Negativni rezultat: Inhibitorska substanca je β-laktamski antibiotik.
Positive result remains: Inhibiting substance cannot be identified by this procedure, continue with 2.
Pozitivni rezultat ostaja: Inhibitorske substance s tem postopkom ni mogoče razpoznati, nadaljujte s točko 2.
The presence of sulfonamides can be confirmed by repeating the test adding p-amino benzoic acid to the test system:
Prisotnost sulfonamidov lahko potrdite s ponovitvijo preskusa z dodatkom p-amino benzojske kisline preskusnemu sistemu:
Negative result: Inhibiting substance is a sulfonamide.
Negativni rezultat: Inhibitorska substanca je sulfonamid.
Positive result remains: Inhibiting substance cannot be identified by this procedure, continue with 3.
Pozitivni rezultat ostaja: Inhibitorske substance s tem postopkom ni mogoče razpoznati, nadaljujte s točko 3.
The presence of a combination of a β-lactam and sulfonamide can be confirmed by repeating the test adding pencillinase + p-amino benzoic acid to the test system:
Prisotnost kombinacije β-laktama in sulfonamida lahko potrdite s ponovitvijo preskusa z dodatkom penicilinaze + p-amino benzojske kisline preskusnemu sistemu:
Negative result: Inhibiting substances are a β-lactam antibiotic and a sulfonamide.
Negativni rezultat: Inhibitorska substanca je β-laktamski antibiotik in sulfonamid.
Positive result: Inhibiting substance cannot be identified by this procedure.
Pozitivni rezultat: Inhibitorske substance s tem postopkom ni mogoče razpoznati.
Important notice: False-positive results may be obtained, when skimmed-milk powder is analysed.
Pomembna opomba: Pri analizi posnetega mleka v prahu so rezultati lahko lažno pozitivni.
It is important, therefore, to verify that the test system used does not yield false-positive results.
Zato je zelo pomembno preveriti, da uporabljeni preskusni sistem ne daje lažno pozitivnih rezultatov.
Some β-lactams are less sensitive to β-lactamase.
Nekateri β-laktami so manj občutljivi na β-laktamazo.
In such cases an additional pre-treatment of the sample, (1 ml of test sample with 0,3 ml of penase concentrate at 37 °C for 2 h) is recommended.
V takšnih primerih se priporoča dodatna predhodna obdelava vzorca (1 ml preskusnega vzorca z 0,3 ml koncentrata beta-laktamov pri 37 °C za 2 uri).

V najmanj 95 % obdelanih primerov razlika dveh vzporednih analiz istega vzorca v dveh laboratorijih ne sme biti večja od 6,5 g posnetega mleka v prahu v 100 g krmne mešanice.
OBSERVATIONS
UGOTOVITVE
The addition of large percentages of certain non-milk proteins and especially of soya proteins, when heated together with skimmed-milk powder, may lead to too high results due to co-precipitation with the para-casein of milk.
Če je dodan visok odstotek nekaterih nemlečnih, zlasti sojinih beljakovin, lahko to pri segrevanju skupaj s posnetim mlekom v prahu povzroči previsoke rezultate zaradi skupnega usedanja s parakazeinom mleka.
Addition of buttermilk may lead to somewhat low figures, due to the fact that only the non-fat portion is determined.
Dodatek pinjenca lahko povzroči nekoliko nizke rezultate, ker se določajo samo nemlečni proteini.
Addition of certain acid buttermilk may give considerably low figures, due to incomplete dissolving in the citrate solution.
Dodatek nekega kislega pinjenca lahko povzroči izrazito nizke vrednosti zaradi nepopolnega raztapljanja v raztopini citrata.
Lecithin additions of 0,5 % or more may also lead to low results.
Dodatek 0,5 % ali več lecitina lahko prav tako povzroči nizke vrednosti rezultatov.
Incorporation of high-heat skimmed-milk powder may lead to too high figures due to the co-precipitation of certain whey proteins with the para-casein of milk.
Vključevanje močno segretega posnetega mleka v prahu lahko privede do previsokih vrednosti zaradi skupnega usedanja nekaterih sirotkinih beljakovin s parakazeinom mleka.

DETECTION OF STARCH IN SKIMMED-MILK POWDER, DENATURED MILK POWDER AND COMPOUND FEEDINGSTUFFS
DOLOČITEV ŠKROBA V POSNETEM MLEKU V PRAHU, DENATURIRANEM MLEČNEM PRAHU IN KRMNIH MEŠANICAH
This method is for the detection of starch which is issued as a tracer in denatured milk powders.
S to metodo se ugotavlja škrob, ki je pokazatelj za denaturirani mlečni prah.
Limit of detection of the method is approximately 0,05 g of starch per 100 g of sample.
Meja ugotavljanja pri tej metodi je približno 0,05 g škroba na 100 g vzorca.
The reaction is based on the one used in iodometry:
Reakcija temelji na tisti, ki se uporablja v jodometriji:
fixation by the colloids of the free iodine in aqueous solution,
fiksacija s koloidi prostega joda v vodni raztopini,
absorption by the starch micelles and by colour formation.
absorpcija s škrobnimi micelami in tvorbo barve.
Iodine solution
Raztopina joda
Iodine: 1,0 g,
Jod: 1,0 g,
Potassium iodine: 2,0 g,
Kalijev jodid: 2,0 g,
Distilled water: 100 ml,
Destilirana voda: 100 ml,

Dodajte 0,5 ml raztopine joda (3.1), stresite in opazujte nastalo barvo.
A blue colouration indicates the presence of native starch in the sample.
Modra obarvanost kaže na navzočnost nemodificiranega škroba v vzorcu.
When the sample contains modified starch the colour may not be blue.
Če vzorec vsebuje modificirani škrob, se ta morda ne obarva modro.
The colour, the intensity of the colour and the microscopic appearance of the starch, will vary depending on the origin of native starch (e.g. maize or potato) and the type of modified starch present in the sample.
Barva, jakost barve in mikroskopski videz škroba se spreminjajo glede na izvor nemodificiranega škroba (npr. koruzni ali krompirjev) in na vrsto modificiranega škroba, ki je v vzorcu.
In the presence of modified starches the colour produced turns violet, red or brown, according to the degree of modification of the crystalline structure of native starch.
V prisotnosti modificiranega škroba se nastala barva spremeni v vijolično, rdečo ali rjavo v skladu s stopnjo modificiranosti kristalne strukture nemodificiranega škroba.
