How Vibe analyzers were used
Grain length, length-breadth ratio, and chalkiness of zinc-biofortified and control rice varieties in Bolivia and Colombia were measured with a Vibe QM3 image analyzer and linked to consumer sensory acceptance scores from 243 adults.
Study overview
Biofortification aims to address zinc deficiency by breeding staple crops with higher micronutrient content, but adoption depends on consumer acceptance. This study characterized grain quality — including grain length, length-breadth ratio, and endosperm chalkiness, measured with a Vibe QM3 image analyzer — and sensory acceptability of zinc-biofortified rice varieties alongside local controls in Bolivia and Colombia. Sensory acceptability was evaluated in 243 adults using a 7-point hedonic scale. In Bolivia, biofortified variety T2-11 and the control were equally accepted with no significant difference; in Colombia, biofortified variety 035 scored higher in overall acceptance than the other biofortified variety and the local control, supporting the viability of zinc-biofortified rice for wider adoption.
