Experimental Data for Publication 'Treatment of fruit juices with β-glucosidase for release of aroma glucosides'

Abstract

The data set contains determined specific activities of a recombinant beta-glucosidase (family BglA) and the industrial product Rapidase under varying conditions (temperature, pH, sugar concentration, storage etc.). Specific activities have been determined via a spectrophotometric assay. Outliers have been removed. Both enzymes were then used to treat 4 different juice varieties (apple, apple mango, apple raspberry, grape) for 24 h at ambient temperature. The headspace of the treated juices was analysed via SPME GC-MS and compared to fresh and aged juice samples (24 h at ambient temperature). The list of compounds identified via the Tracefinder software of the treated juices and the enzymatic solutions prior to retention time alignment is included in this data set.

Data has been generated at the University Bielefeld (Industrial Organic Chemistry and Biotechnology) and the University of Nottingham (International Flavour Research Centre, School of Biosciences) and collaboratively analysed as per the jointly-awarded PhD program with the University of Adelaide.
