Charm Peel Plate YM Microbial Test for Dairy, Food Dilutions, and Enviromental Samples
The Charm® Peel Plate® YM Microbial Test (Peel Plate YM) is a simplified culture
method for detection of fungal micro-organisms.
Each plate contains prepared media
in a shallow dish with an adhesive top. Quickly pipette the test sample in the middle
of the plate and it automatically wicks through the media and solidifies. No spreading
device is needed. Invert the test and stack up to 20 together for efficient incubation.
The Peel Plate YM is based on potato dextrose media and both yeast and mold will
produce blue/green colonies for easy visual identification. An air gap between the
plate and cover allows colony picking for additional isolation and identification.
Benefits of the Peel Plate YM Test Include
Ready-to-use. Just add sample/dilution. No spreading device needed.
Etched grid lines for estimated counts.
Colonies easily picked for additional isolation/classification.
Convenient plate stacking for improved air circulation.
Buffered formulation – pH not required for most samples.
12 month refrigerated shelf-life in a resealable foil zip bag.
47 mm diameter convenient for water filters and 100 mL water samples or larger.
AOAC-RI Validated Matrices.
5 mL high volume test available.
Automated counting and data storage when used with the Charm Peel Plate
Colony Counter
FOR DETECTION AND ENUMERATION OF YEAST AND MOLD
The Peel Plate YM test is based on potato dextrose medium to support and colorimetrically identify
the growth of yeast and mold at 25 ± 3 oC in the dark. The Peel Plate YM test contains the
enzyme substrates that turn blue when detecting phosphatase and glucosidase enzymes that
are produced by growing fungi. Peel Plate YM tests also contain gelling and wicking agents which
absorb and diffuse the sample.
The Peel Plate YM method has been certified by the AOAC Research Institute as Performance
Tested Method 061601.
This test kit’s performance was reviewed by AOAC-RI and was found to
perform to the manufacturer’s specifications. The Peel Plate YM test has been validated at 25 oC ±
3 oC for 3 to 5 days in 2 % milk, cottage cheese, sour cream, yogurt, vanilla ice cream mix, mixed
fruit, sliced apples, orange juice, grape juice, corn flour, flour tortillas, salad dressing, hummus,
breaded fish sticks, and sponge rinse samples from stainless steel surfaces and found to not
be significantly different from the dichloran rose bengal chloramphenicol agar (DRBC) reference
method. Samples should be 10-fold serially diluted into the countable range of 1 to 150 CFU/mL.
Counts less than 10/plate are considered estimated counts.
