Influence of different levels of ethnocentrism of the Brazilian consumer on the choice of dulce de leche from different countries of origin

Importance of the origin, organic production and other extrinsic parameters in fruit and vegetable choices

The aims of the present work were to evaluate consumers' perceptions and purchasing habits in relation to fruit and vegetables and to determine the importance of the production type, price and geographical origin of such products for consumers' purchasing decisions. For this purpose, an online consumer survey was conducted to determine Spanish people's opinions and consumption habits in relation to fruit and vegetables, especially those from organic farming. The survey also included a part to assess the importance that consumers attach to different extrinsic attributes in oranges and avocado pears (with a conjoint analysis), and a section to determine the participants' ethnocentrism. Consumers agree that organic food respects the environment more, contains fewer 'chemicals' and is more natural. Price is the first reason why many people do not buy organic food, followed by them thinking that they do not offer any added value and they are difficult to find. For the Spanish population, country of origin, local production, seasonality and price are much more important attributes for purchasing fruit and vegetables than them being organic. This study reflects a relatively high ethnocentrism level of the surveyed population, especially in older individuals. Given consumer preference for km 0/local and seasonal products, and the importance of these parameters for the environment, promoting the market of such products would help to achieve some Sustainable Development Goals. This study offers a vision of the trends of Spanish consumers in relation to fruit and vegetable preferences, which can help producers and distributors to design new strategies that focus on meeting consumer demands.

The country-of-origin label impact on intention to consume insect-based food

The global food consumption scenario and the influence of a country's image on consumer decision-making motivated this research. The global edible insect market is growing, and cultural issues, disgust, and low perception of quality are barriers to consumption. Through an online experiment (n = 194) Brazilian consumers demonstrate that the use of the country-of-origin label (COOL) can result in greater intention and quality expectation regarding a cricket flour. Consumers showed a preference for the flour produced by a positive image country label. Both intention and quality expectation were higher for the cricket flour produced in the United States. Furthermore, the mediation model indicates that quality expectation mediated the effect of COOL on the intention to consume. The results show that even though consumers have created a positive expectation concerning the product, a higher level of neophobia diminished their intention to consume the product and this relates to the aversion and disgust that can exist towards an edible-insect product. The neophobia level can weaken the effect of COOL on intention mediated by quality expectation. The study aimed to contribute to a better understanding of the consumer's perception of an insect-based food and provide insights into variables related to the intention to consume by verifying their contribution to the consumer's behavior.

The impact of packaging design on the perceived quality of honey by Brazilian consumers

This study aimed to construct and validate a scale to evaluate the honey consumer perception. Furthermore, the impact of packaging design on honey's perceived quality and purchase intention was evaluated. Brazilian consumers (n = 343) answered the 21 self-descriptive statements of the scale using 7-point Likert scales. Furthermore, six different packages were presented, and the consumer perception (health, origin, safety, and taste) and purchase intention were evaluated using 5-point and 7-point Likert scales, respectively. Exploratory and confirmatory factor analyses and PLS path modeling were employed. The validated scale had 13 self-descriptive statements (indicators with factor loading higher than 0.4) and showed discriminant (heterotrait-monotrait ratio values < 0.85) and convergent validity (average variance extracted > 0.4) and adequate reliability (composite reliability > 0.70). The consumers associated honey with health properties and a safe product. Furthermore, they preferred honey purchased directly from producers due to its perceived quality (natural and pure). Honey packaged in glass jars with or without dipper was perceived as healthier, tastier, higher quality, and from trusted origin. Furthermore, glass jars were considered more practical and sustainable packages.

Lactiplantibacillus plantarum CCMA 0743 and Lacticaseibacillus paracasei subsp. paracasei LBC-81 metabolism during the single and mixed fermentation of tropical fruit juices

Fruit juices have shown promising results as new probiotic carriers. This study aimed to evaluate acerola, jelly palm, and passion fruit juices as substrates for fermentation using Lactiplantibacillus plantarum CCMA 0743 and Lacticaseibacillus paracasei LBC-81 in single and mixed cultures. First, the juices were evaluated as substrate and selected based on bacterial growth performance during fermentation. Afterward, the impact of fermentation on sugars, organic acids, and bioactive compounds was also appraised. Phytochemical modification of three different juices fermented by lactic acid bacteria at 37 °C/24 h was evaluated. After 18 h of fermentation, passion fruit juice showed higher cell viable counts of single and mixed L. plantarum CCMA 0743 culture, above 9.00 Log CFU/mL, and pH between 4.07 and 4.10. Sugars consumption and organic acid production were influenced by juice composition and culture used. The mixed culture reduced the total sugars in the passion fruit juice by approximately 53.0% (8.51 g/L). Lactic acid was the main product of the sugars fermentation, with higher concentrations detected in passion fruit juice (8.39-11.23 g/L). Bioactive compounds were analyzed on the selected substrate. The fermentative process reduced antioxidant activity and carotenoid content. However, single L. plantarum CCMA 0743 culture increased the yellow flavonoid content of passion fruit juice by approximately 3.0 µg/mL. L. plantarum CCMA 0743 showed high and suitable cell, viable counts, to claimed probiotic products, increasing bioactive compounds in passion fruit juice. Therefore, this strain and passion fruit substrate showed attractive potential to produce alternative and functional fermented fruit beverages.
