Rice quality: How is it defined by consumers, industry, food scientists, and geneticists?

ABSTRACT: Background:Quality is a powerful engine in rice value chain upgrading. However, there is no consensus on how "rice quality" should be defined and measured in the rice sector. Scope and approach:We adopt a Lancasterian definition of rice quality as a bundle of intrinsic and extrinsic attributes. We then review how rice quality is (i) perceived and defined by consumers and industry stakeholders in rice value chains in Southeast and South Asia; (ii) measured and defined by food technologists; and (iii) predicted through genetics. Key findings and conclusions:Consumers are heterogeneous with respect to their perceived differentiation of rice quality among regions, countries, cities, and urbanization levels. Premium quality is defined by nutritional benefits, softness and aroma in Southeast Asia, and by the physical appearance of the grains (uniformity, whiteness, slenderness), satiety, and aroma in South Asia. These trends are found to be consistent with industry perceptions and have important implications for regional and national breeding programs in terms of tailoring germplasm to regions and rice varieties to specific local market segments. Because rice is traded internationally, there is a need to standardize definitions of rice quality. However, food technologists have not reached unanimity on quality classes and measurement; routine indicators need to be complemented by descriptive profiles elicited through sensory evaluation panels. Finally, because rice quality is controlled by multiple interacting genes expressed through environmental conditions, predicting grain quality requires associating genetic information with grain quality phenotypes in different environments.

Project description:This study aimed to investigate food truck consumers' profile, choices, preferences, and food safety importance perception. We conducted structured interviews with a convenient sample of 133 food truck consumers in the Federal District, Brazil. Most of the participating consumers were married (52%) and female (56%), who had completed at least tertiary school (81%). The interviews revealed that most food truck consumers eat from food trucks once or twice a week (96%), usually near home (74%), and have an average per capita expenditure of approximately US $5 to US $9.99 (70%). Hamburgers and sandwiches are the most popular food among consumers (72%). Consumers indicated that taste (30%) was the most important reason to choose a food truck and that poor vehicle hygiene (30%) was the main point assigned for not opting for a food truck. Food hygiene and vendors' personal hygiene were considered important by consumers when eating from food trucks (78% and 80%, respectively). Considering all food truck consumers interviewed and the questions about food safety importance perception, the minimum score was 1 and the maximum was 2.9, with a mean score of 1.68 (SD = 0.46), indicating a high level of perceived importance. The instrument of food safety importance perception presented a Cronbach's alpha coefficient of 0.73, indicating good internal consistency. No significant differences were observed in the food safety importance perception scores in gender (0.192), marital status (0.418), level of education (0.652) or food safety training (0.166). However, significant differences were found in the food safety importance perception scores for age (0.026) and the presence of children (0.001). The findings of this study indicate that there remains the need for consumers to comprehend their role in the food supply chain. Food safety and food handling practices are of public concern, and strategies are required to prevent foodborne diseases. Future public health interventions aiming to increase consumer knowledge and awareness of food safety should be emphasized.
