MALTANALYZER
GET A CLEARER PICTURE OF YOUR MALT QUALITY
With the MaltAnalyzer from UNIT-ONE you can examine the modification of the malt – the breakdown of the grain’s cell structure that takes place during malting.
UV light and image analysis help you assess the sample and provide a basis for quality control.
BENEFITS OF THE MALTANALYZER
Less manual
analysis work
Automated processes support the analysis and save time in the laboratory.
Easy to operate
in daily lab work
User-friendly operation makes the instrument accessible in everyday work.
A better basis for comparison
Use the analyses to examine differences between malt samples and to monitor quality.
What does the analysis show?
During malting, parts of the grain’s inner cell structure are broken down. This is called modification, and it affects how the malt can be used further on in the process.
The MaltAnalyzer uses UV light and fluorescence to examine the halved malt kernels. With the cut surface facing up, the inside of the kernels can be analysed, giving you a picture of the modification in the sample.
As a laboratory technician, you get help assessing how homogeneous the malt is and examining differences between samples. This gives you a better basis for monitoring quality and passing any deviations on to those responsible for production.
FROM SAMPLE TO ANALYSIS
Prepare the sample
The malt kernels are halved and prepared for analysis.
Place the sample
The halved kernels are placed in the sample holder with the cut surface facing up.
See the result
The sample is analysed, and the result is used to assess the modification of the malt.
See what the analysis tells you
A concrete analysis result makes it easier to understand the knowledge the instrument provides.
What do the markings show?
The black-and-white image shows a sample block under UV light: 50 halved, stained malt kernels in a 10 × 5 grid. Unmodified cell walls fluoresce brightly, while modified areas appear dull. The software measures every kernel and places it in a modification class from 0 (unmodified) to 5 (fully modified). The first table shows the class of each kernel, row by row (R1–R5) and column by column (C1–C10), and the second table shows the measured unmodified area of each kernel. Two blocks, A and B, are analysed and combined in one report, so the result is based on 100 kernels.
What should you look for?
The Score line at the bottom shows how many kernels fall into each class (G0–G5). From this the program calculates M = Modification and H = Homogeneity using the Carlsberg Modification and Homogeneity method. A high M means well-modified malt, and a high H means the kernels are evenly modified. Many kernels in the low classes, or large differences between kernels in the same block, point to uneven modification. As an example, the demo sample 140A gives M = 97.75 and H = 90.4.
WHAT YOU CAN USE THE ANALYSIS FOR
Examine the modification
Gain insight into the changes inside the malt kernels as a supplement to the laboratory’s other tests.
Assess homogeneity
Take a closer look at differences between
the kernels in the same sample, and
examine the variation.
Compare malt samples
Examine malt from different
deliveries under comparable
analysis conditions.
