Verification of Mycotoxin Patulin from Apple Juice with Isocratic HPLC
The permitted daily exposure for the mycotoxin patulin is 0.05 µg/mL in apple juice, as stated by the Scientific Committee on Food for the European Commission. In this application note, KNAUER presents a fast protocol for the determination of patulin from apple juice using the AZURA® HPLC plus with a Eurospher II column.
Scale-Up of an Analytical HPLC Method for Steviol Glycosides to a Preparative Approach
In this application note, KNAUER describes how an existing analytical HPLC method can be transformed to a preparative HPLC using the KNAUER Scale-Up Converter. The example used in this application is steviol glycosides, which are often used as natural sugar substitutes due to a far higher sweetening power than normal sucrose or glucose. However, this approach is also designed to be applicable for the fast scale-up of other analytes.
Quantification of Steviol Glycosides in Stevia Samples with RP-HPLC
In this application note, KNAUER provides a method that promises fast determination of six steviol glycosides. The AZURA® HPLC plus system is designed for fast separation in under ten minutes and an optimized gradient, promising fast quality control of Stevia products.
Determination of Vanillin and Associated Marker Substances
With the continuous increase in the price of vanilla pods, artificial vanilla flavoring agents such as vanillin are in high demand. In this application note, KNAUER outlines a method using the AZURA® UHPLC system for screening the components of different vanilla products to determine authenticity.
Quantitative Determination of Primary Aromatic Amines in Recycled Cold-Cure and Flexible Foams
A reliable method for the quantification of aryl amines in cold-cure and flexible foams from recycled mattresses is described in the following application. The focus was set on two substances, 2,4-diaminotoluene (TDA) and 4,4-diaminodiphenylmethane (DAPM), which are mandatory to be determined before processing the recycled foam due to their carcinogenic properties.
Alternative Xylitol Extraction via HPLC Purification from Fermented Biomass
A latest approach in bioethanol generation is the usage of yeast and bacteria that uses C5 sugars for fermentation and the valorization of bio refinery by products. Here it is shown that a hemicellulose-like fermentation mash has a high content of the artificial sweetener xylitol and that its purification by HPLC can be accomplished using polymer based Eurokat columns. The product is soluble in water and can easily be used for further applications.
