“…Pitaya thrives at 18–27 °C, but an extreme temperature of 39 °C is not suitable [ 128 ]. Cold damage is the biggest issue in northern China [ 129 , 130 ], while a humid climate causes pests and diseases in pitaya produced in Malaysia [ 131 , 132 ]. A study reported that fresh-cut pitaya fruit storage at 5–10 °C increased the accumulation of total soluble phenolics reactive oxygen species and improved antioxidant activity [ 133 , 134 ].…”

Pitaya (Hylocereus spp.) is a member of the cactus family that is native to Central and South America but is now cultivated throughout the sub-tropical and tropical regions of the world. It is of great importance due to its nutritional, ornamental, coloring, medicinal, industrial, and high consumption values. In order to effectively utilize and develop the available genetic resources, it is necessary to appreciate and understand studies pertaining to the usage, origin, nutrition, diversity, evaluation, characterization, conservation, taxonomy, and systematics of the genus Hylocereus. Additionally, to gain a basic understanding of the biology of the plant, this review has also discussed how biotechnological tools, such as cell and tissue culture, micropropagation (i.e., somatic embryogenesis, organogenesis, somaclonal variation, mutagenesis, androgenesis, gynogenesis, and altered ploidy), virus-induced gene silencing, and molecular marker technology, have been used to enhance pitaya germplasm.

“…A pitaya ou pitaia (gênero Hylocereus), é um fruto exótico apreciado por seus atributos sensoriais e valor nutricional (Covino et al, 2015;Gong et al, 2019;Magalhães et al, 2019). A pitaya é rica em flavonoides e fonte de minerais e vitaminas (C e complexo B), além de possuir elevados teores de fibra, nitrogênio, potássio, cálcio, ferro, manganês e zinco (Cordeiro et al, 2015).…”

As barras de cereais são exemplos de alimentos que combinam saúde e praticidade, além de apresentarem possibilidades de inclusão de nutrientes benéficos à saúde. A pitaya (gênero Hylocereus), é um fruto exótico apreciado por seus atributos sensoriais e valor nutricional. A utilização da casca da pitaya tem grande potencial no desenvolvimento de produtos alimentícios. O objetivo desse estudo foi o desenvolvimento de barra de cereal adicionada de farinha de casca de pitaya e avaliação de suas características físico-químicas e sensoriais. Foram produzidas cinco barras de cereais (B0, BFL5, BFL10, BFC5 e BFC10). As médias dos valores de proteínas das BFC5 e BFC10 foram menores em comparação com a B0 e quanto ao teor de carboidratos, a B0 teve o menor resultado e se diferenciou das demais. Foi identificado menores teores de lipídeos (6,03 a 8,63%) em todas as formulações, com exceção da B0. Quanto ao teor de fibra alimentar, o valor médio apresentado pela amostra BFL10 (5,89±0,00) diferiu dos valores das amostras B0 (6,62±0,37) e BFL5 (7,04±0,59), significando que a adição das farinhas desidratadas não representou acréscimo de fibras nas formulações. O resultado obtido da capacidade antioxidante foi significativo e superior para a formulação BFL5 (30,91±1,55). Quanto à concentração de fenólicos totais, a formulação BFC10 (1,07±0,06), apresentou valor médio acima das demais. Em relação aos parâmetros de aroma, textura, sabor e aceitabilidade global analisados no teste sensorial de aceitação, não houve diferença estatística entre as médias obtidas pelas formulações. Houve efeito positivo da adição da casca de pitaya nas características físico-químicas e sensoriais das barras de cereais, com destaque para as formulações com maiores concentrações de farinhas de cascas de pitayas, desidratada pelo método de liofilização e convencional em estufa.

Pharmaceutical compounds are a serious problem in the environment. They cause damage to the aquatic, animal, and human organisms and soon became considered emerging pollutants where their removal is extremely urgent. Among the techniques used, adsorption has been used with success, where several adsorbent materials, including those from residual biomass, have been used to remove these pollutants. In this study, the skins of the pitaya fruit (Hylocereus undatus) productive chain were carbonized with ZnCl2 to obtain activated carbon and later used in the adsorption of the drug naproxen (NPX) in a batch system. The Freundlich model demonstrated a better adjustment for the equilibrium isotherms. A high adsorption capacity for NPX (158.81 mg g −1 ) was obtained at 328 K, which can be attributed to the remarkable textural properties of the adsorbent, besides certain functional groups present on its surface. Thermodynamic studies confirmed the endothermic nature of the adsorption process (∆H 0 = 0.2898 kJ mol −1 ). The linear driving force model (LDF) presented a good statistical adjustment to the experimental kinetic data. The application of the material in the treatment of simulated wastewater composed of various pharmaceutical drugs and salts was very promising, reaching 75.7% removal. Therefore, it can be inferred that the application of activated carbon derived from pitaya bark is highly promising in removing the NPX drug and treating synthetic mixtures containing other pharmaceutical substances.
