Assessing consumer perception, sensory acceptance and nutritional composition of radish microgreens

Abstract Purpose: Microgreens, young-tender green leafy plants, are being valued for their vibrant appearance, rich flavors and nutrient-rich profile, yet remain an underexplored area. Hence, the study was undertaken to analyze consumer perception towards microgreens, as well as to evaluate the sensory characteristics and nutritional composition of three microgreen varieties (white, purple, and pink radish). Methods: A pre-tested online questionnaire was used to assess consumer awareness and perception using 610 respondents aged 20-35 years. To identify the barriers to purchasing microgreens, a ranking method was applied, while consumer perceptions were evaluated using a 5-point Likert scale. The sensory attributes of microgreen varieties were evaluated using a semi-trained panel comprising 20 members. Additionally, the nutritional composition and antioxidant properties were assessed across the three selected varieties. Results: The study surveyed 610 respondents, out of which 65.58% (400 respondents) were familiar with microgreens and hence were included in the study. The majority of participants had a positive perception regarding microgreens, with 84.25% acknowledging potential health benefits. Sensory evaluation of three radish microgreens revealed that all varieties scored well for overall acceptability, indicating positive inclusion potential of microgreens in daily diets. Proximate analysis revealed high moisture, moderate protein and low-fat among the varieties. Calcium, iron, magnesium, copper and zinc were also present. High levels of ascorbic acid, chlorophyll, total phenol and total flavonoids content were found in all the assessed varieties, with purple radish demonstrating the strongest antioxidant activity. Conclusion: Overall, results highlight positive consumer perception, unique sensory profile and high nutritional potential of radish microgreens.
