Enzymatic fruit juice analysis

For years enzymatic fruit juice analysis methods have an important place in laboratories for controlling of raw materials, production process and end products. Therefore enzymatic fruit juice analysis methods are contained in the method books of national and international associations in fruit juice industry, as well as in governmental locations (EN, IFU, AIJN, national food laws).
As like many other analytical fruit juice analysis methods, enzymatic analysis was used first in clinical chemistry and then the methods were introduced for the determination of fruit juice ingredients. Due to the high specificity of the enzymes this fruit juice analysis method has enabled the analysis of fruit juice matrices without the need of complicated sample preparation techniques. This makes enzymatic fruit juice analysis a common method for manufacturers of fruit juice products, trade companies and in the governmental food inspection.


Automated enzymatic fruit juice analysis

Due to the fact that batch sizes in fruit juice productions becomes bigger and capacity of filling lines increased by higher speed, fruit juice analysis becomes more important. The risk to lose a lot of money by a not detected hygiene problem or false recipe is very high. Unique DiaSys reagents for fruit juice analysis enable the quality control to prevent problems before they occur. All DiaSys fruit juice analysis reagents are designed for use on automated systems. Combination of liquid and stable DiaSys reagents and automation speed up fruit juice analysis in the same way as filling lines and production capacity becomes faster and bigger.


Enzymatic fruit juice analysis with reagents from DiaSys

Founded in 1991 DiaSys is a company focusing in the development and manufacture of high-quality ready-to-use reagents for Clinical Chemistry Tests. With more than 150 employees at Holzheim (between Frankfurt and Cologne / Germany), DiaSys manufactures liquid stable reagents for customers worldwide. Thereby DiaSys was the first company in Europe specialising in developing and manufacturing liquid and ready to use reagents in clinical diagnostics.
Whereas the existing methods in clinical field were transferred to convenient methods using liquid stable reagent, enzymatic fruit juice analysis methods did not change. In order to express the needs in fruit juice analysis DiaSys decided to modernize the enzymatic fruit juice analysis by the transfer and adaptation of their knowledge in development of liquid and stable test-kits for clinical chemistry. Using innovative research, development and manufacturing techniques DiaSys produces the highest quality, liquid stable ready to use reagents for enzymatic fruit juice analysis analysis.


The benefits of DiaSys reagents for fruit juice analysis

· Ease of use:
No errors and no time wasted in reconstitution by using the liquid and ready to use fruit juice analysis reagents. Furthermore the pipetting steps are minimized by the use of 2 or maximum 3 reagents per assay. In case of 3 reagents two can be used premixed. The pipetting order is user friendly by standardization on a 4+1 or 4+1+1 format.
· Online monitoring:
All fruit juice analysis methods reached endpoint in less than 5 min at 37 °C. Combination from simplified assay procedure and incubation at 37 °C allows online monitoring of production processes.
· Cost-efficient by automation:
All fruit juice analysis tests can be adapted easily for use on fully automated systems like Vitalab Selectra, Konelab, Respons, Hitachi, LISA etc. (applications on request). Combination of less reagent consumption and high speed fruit juice analysis prevent problems before they occur.
· Environmental friendly:
The fruit juice analysis reagents are not hazardous. Due to the liquid and stable form the fruit juice analysis reagents are always available when needed and can be used up to the very last drop.
