Mapping Consumer Preference for Vegan and Omnivorous Diets for the Sensory Attributes of Flour Products with Iodine-Fortified Plant-Based Ingredients
Objectives: Flour products with iodine-fortified dried vegetables can be a good source of iodine. However, in addition to iodine stability, the sensory quality of these products is also important. Therefore, this study aimed to assess the effect of adding iodine-fortified dried vegetables to flour products (gnocchi and ciabatta) on their sensory quality and map consumers (vegan/omnivore diets) as potential consumers of fortified flour products with iodine-fortified dried vegetables. Methods: A quantitative analysis of the sensory desirability and profiling were used to achieve the work objective. Results: It was confirmed that there was no relationship between the form of iodine (without iodine/KIO3/KI) and the intensity of all definite descriptors of colour, aroma, and taste. We also confirmed the relationship between the vegetable type and the descriptors’ intensity. It was confirmed that the positive attribute with the highest impact was the pumpkin taste, and the attribute with the most negative impact was the cauliflower aroma. This was true for consumers on vegan and omnivore diets, and they confirmed the most positive attitude toward the taste of pumpkin. Conclusions: Introducing dried iodine-fortified vegetables (gnocchi dumplings 24%; ciabatta rolls 5%) allows for the high sensory desirability of designed products. Introduced iodine (gnocchi dumplings 30 mg I/100 g; ciabatta rolls 9–11 mg I/100 g) does not change products’ sensory profiles.
Analysis of Sensory Attributes and Purchasing Decisions of Plant-Based Beverages of Young Consumers in Poland on a Vegan and Traditional Diet
This study aimed to analyse young consumers’ behaviour in Poland toward the consumption of plant-based beverages as milk alternatives. The sensory analysis included oat, buckwheat, cashew, almond, soy, pea, rice, coconut, hazelnut, and macadamia nut beverages and their mixtures. Quantitative analysis of sensory desirability and sensory profiling were employed to evaluate plant-based beverages. The study was conducted among young people (aged 18–35) who declared a vegan or omnivorous diet. It was found that the most frequently consumed beverages included oat and soy beverages, both among vegan and traditional (omnivorous) young groups. A significantly lower frequency of plant-based beverage consumption was confirmed in the group of people with an omnivorous diet. The taste characteristics in plant-based beverages are a key factor in driving sensory desirability among young consumers. Analysis of the influence of respondents’ declared diet and gender revealed no significant differences in the desirability of the taste of the plant-based beverages. The consumers rated the coconut, pea, macadamia, oat, and rice–coconut beverages as the most desirable in terms of taste. The lowest taste desirability was confirmed for the soy drink despite its high reported consumption. The importance of this study focused on the local market development in vegan food, as well as its potential due to further consumer expectations.
