Abstract Media and food advertisements today represent important industrial strategies for the differentiation, promotion and selling of products. Thus, they can exert a strong influence on consumer buying and consumption behaviour. Considering this, the objective of this work was to evaluate the perception of consumers about the media and its influence on food purchasing behaviour through a market research survey with consumers from two municipalities in the south of Minas Gerais State, Brazil. A non-probabilistic sample was used for convenience, totalizing 285 respondents (150 in Varginha and 135 in Lavras), and an interview with questions prepared by the researchers themselves being used as the research instrument. The data were analysed in a descriptive way. Based on the results, it could be seen that, for the sample under study, food consumption could be influenced by the media and by the food advertisements. Exposure to these ads may also be related to opinions about what is most valued in the purchase of food, such as practicality and convenience. Regarding the reading of labels, a low frequency of consumers who frequently read this information was observed. Together, these results reinforce the evidence that marketing strategies have the potential to influence the eating behaviour of the subjects, and, therefore, also contribute to the achievement of public health goals for food and nutrition. In this case, the importance of food and nutritional education strategies for the training of more autonomous and critical consumers regarding their food choices is highlighted.

Abstract Recently, many researches have become available in order to value agroindustrial waste and by-products through processes that exploit these wastes and transform them into new value-added products. Thus, this study aimed to assess the chemical composition (proximate analysis, mineral profile, pectic substances, carbohydrates), fatty acid profile, and bioactive compounds of two major exotic fruit wastes (seeds), marolo and soursop, largely found in one of the richest Brazilian biomes, the Savannah. Soursop and marolo seeds showed significant fat (295.1 and 311.3 g kg-1 d.b., respectively), protein (149.9 and 188.7 g kg-1 d.b., respectively), and fiber (426.7 and 351.1 g kg-1 d.b., respectively) contents. Marolo seeds were found to be the richest in phenolic compounds (32043.1 mg GAE kg-1 d.b.) and also presented the highest DPPH• scavenging activity (91.25%). The major phenolic compound found in marolo and soursop seeds was rutin. Among the fatty acids found in both seeds, the ones with unsaturated chains were predominant, such as oleic acid (48.54% for marolo, and 40.35% for soursop seeds). The seeds analyzed were found to be sources of Cu and Mg. Marolo and soursop seeds were found to be a good source of nutritional compounds and an alternative to obtain compounds of interest to be used in the development of food produce, pharmaceutical, and cosmetic products.
