A flora brasileira apresenta uma grande diversidade, e o mercado de frutas representa uma atividade de grande importância econômica para o país. A ingestão de compostos fenólicos, oriundos de frutas, está associada a vários efeitos benéficos e prevenção de condições patológicas. O presente estudo consiste em uma revisão crítica sobre o teor de compostos fenólicos totais e flavonoides em relação ao preço de mercado de seis frutas nativas (caju, seriguela, umbu, juá, cajá e pitomba) e em oito frutas exóticas (acerola, carambola, coco, frutapão, graviola, pinha, sapoti, tamarindo) ao Nordeste brasileiro. O levantamento foi realizado a partir de avaliação dos preços divulgados nas plataformas digitais dos Centros de Abastecimento de Alimentos dos estados nordestinos e as concentrações de fenóis totais e flavonoides foram obtidas através de levantamento bibliográfico em bases de dados. Diferenças significativas não foram observadas entre as concentrações médias de compostos fenólicos em frutas nativas e exóticas. Da mesma forma, o teor de flavonoides não apresentou diferença significativa entre os dois grupos. Contudo, foi observado a diferença de aproximadamente R$2,00 entre o preço médio das frutas nativas e exóticas, sendo atribuído menor preço às frutas nativas. Desse modo, as frutas nativas se mostram como fonte de menor custo e com o mesmo valor nutricional em flavonoides e fenóis totais das frutas exóticas avaliadas. No entanto, embora mais dispendiosas, há uma preferência do mercado pela aquisição de frutas exóticas por questões de produção e sabor.

Consumers in Croatia only recently got the opportunity to buy exotic fruits and vegetables. Until now offer was limited to the already known species which could be found on the shelves for decades, and this types can generally be cultivated in Croatia (except bananas, pineapples and several types of citrus). The demand for exotic fruits and vegetables and its cultivation in Western Europe is growing, and this trend is coming to Croatia. In the study conducted for the city of Zadar the correlation of the interest in buying exotic fruit/vegetables and familiarity with the product, the exact definition of the product and the most significant characteristics of kiwano/sweet potatoes was explored. Regression analysis results showed that all three independent variables significantly predict purchase of both kiwano and sweet potatoes. Three segments of consumers with respect to their demographic characteristics were identified using cluster analysis. A more detailed analysis of these groups could serve future researchers in order to segment the market and determine the marketing approach to each of the segments.

The pitahaya or dragon fruit is one of the most representative exotic fruits that Colombia has, with an important, growing international market, but the cultivation and postharvest of this fruit lack sufficient technological support to be more competitive. Therefore, alternatives that provide good-quality products that meet market requirements are very important. Therefore, the objective of this research was to determine the effect of a ripening retardant and ethylene application on the conservation and quality of pitahaya fruits and the possible changes during ripening associated with ethylene, for which a completely randomized design with three treatments was used, corresponding to the application of ethylene (ethephon, 3 mL L-1), 1-methylcyclopropene (1-MCP, 600 mg L-1) and a control, with four replications, for a total of 12 experimental units. The fruits were stored at 18°C with 75% relative humidity. The 1-MCP application significantly decreased the loss of firmness, total soluble solids, loss of fresh mass and respiratory rate. Fruits from the control and ethylene treatment tended toward a climateric respiratory behavior. The total carotenoid content of the fruits was significantly higher in the ethylene application and the control treatment, which was consistent with the color change of the fruits. It can be concluded that the 1-MCP application reduced the ethylene action, slowing the ripening of the dragon fruits.

Many African countries are endowed with rich biodiversity with enormous nutritional and economic prospects, but the majority of these resources are not fully harnessed. Exploring these neglected resources, for example, the Transvaal red milkwood tree [(Mimusops zeyheri) Sond. family: Sapotaceae] is of paramount importance for food and nutritional security as well as economic prosperity. This review provides a critical appraisal of the nutritional and health benefits as well as the economic potential of Mimusops zeyheri. The plant is known for its diverse uses among rural communities. In folk medicine, the decoction from the bark and leaves of Mimusops zeyheri are used for treating wounds and ulcers, while the root is used as an infusion taken to treat candidiasis and other health issues. The nutritional profile of the fruit tree is similar to popular exotic fruits and richer in vitamin C when compared to guava and orange. Mimusops zeyheri is a rich source of vitamins, protein, and fatty acids. Based on the rich chemical pool, especially in the fruit and seeds, it has the potential to provide an accessible, readily available, and affordable enriched functional food with valuable health benefits. However, the successful exploration of Mimusopszeyheri for food security and sustainability requires multidisciplinary research. This will help achieve the envisaged food-nutrition security and poverty alleviation potential of the plant, especially among local communities.

While the ongoing global warming and the economic crisis threaten horticultural and ornamental products production in the Mediterranean region, new challenges and opportunities for renewing plant material occur. Pitaya has great potential as a new crop for Mediterranean growers: it consumes little water and it adapts well to the high temperatures present in the greenhouse. Moreover, the market shows increasing demand of new, healthy exotic fruits and the fruit of these crops are worldwide appreciated as a super fruits. The aim of this study was to investigate the potential of introducing a new type of product that in addition to the aesthetic value can combine functional nutritional characteristics, through a whole chain approach, in order to develop basic knowledges and technical information that may lead to the commercial production of pitaya by small-scale farmers in Italy. The results of this study report and discuss various aspects to support the establishment of pitaya cultivation, such as its propagation by cuttings and micropropagation, greenhouse cultivation practices (through the clarification of the sprouting and flowering phenology as well as the fruit maturation period), while providing also information on the sensory properties and the antioxidant levels which naturally occurring in these fruits.
