Abstract:
Novel soybeans with altered composition offer solutions to off-flavors that limit soybean protein adoption. This study compared volatile profiles and sensory characteristics of raw soy slurries from four soybean types: Patriot (commodity), high oleic/low linolenic acid oil (HOLL) and two HOLL soybean types with reduced anti-nutrient carbohydrates, Tiger and Super (lipoxygenase-free). HS-SPME-GC-MS/MS analysis identified 21 targeted volatile compounds, with Patriot containing the highest levels of off-flavor compounds while Super showed the lowest concentrations. Sensory analysis confirmed Patriot had the strongest painty attributes, while Super exhibited pronounced pea notes. HOLL, Tiger, and Super slurries effectively limited off-flavor production compared to Patriot. Soy products made from Super may have the highest consumer appeal due to its lowest off-flavor levels. These findings highlight how novel soybean types can improve sensory quality and provides insights for breeding and processing strategies to enhance soybean flavor.

The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
