Hence the present study aimed to assess the consumer's attitude toward the physical and sensory attributes of the nutritional supplement.

Methodology: 262 consenting non-diabetic subjects of either gender≥ 40 years of age participated in this cross-sectional study. After enrollment, the subjects were requested to consume 53.8 gm of nutritional supplement dissolved in 195 ml of cold water, followed by an interview-based survey.

Results: Around 66.50% of subjects valued the taste of the nutritional supplements the most, followed by flavor (13.0%), aroma (9.20%), color (5.60%), energizing effect (3.60%), mouth feel (3.10%) and aftertaste (0.50%). The mean score for all the physical and sensory parameters was higher than 5, except for grainy mouth feel (mostly perceived as a negative attribute) and energetic feeling post-consumption. Around 92.4% agreed that the mouth feel of the consumed, oral nutritional supplement was smooth, 75.8% agreed on flavor quality, 70.7% were satisfied with the taste, and 82.8% reported that the smell was pleasant.
