Challenges and opportunities in the analysis of raffinose oligosaccharides, pentosans, phytate, and glucosinolates

In this paper, the status of the analytical technologies for assaying animal antinutritional compounds, such as raffinose oligosaccharides, pentosans, phytic acid, and glucosinolates, is reviewed in terms of selectivity, sensitivity, and sample throughput. The implementation of simplified sample preparation schemes, use of novel separation approaches, and alternate detector technologies are discussed. The challenges and opportunities posed by these assays are highlighted along with the recommendations for best analytical practices. Key Words: Glucosinolates, Pentosans, Phytate, Raffinose, Stachyose
