Abstract(s)
Com a crescente preocupação com o desperdício alimentar e com o meio ambiente, é
urgente o estudo de alternativas sustentáveis que permitam combater o desperdício e
ajudar a natureza.
O presente projeto visa o estudo de uma matriz vegetal de baixo custo e altamente
disponível, como é o caso da banana, no que diz respeito à valorização e reaproveitamento
da sua polpa, mas essencialmente do seu subproduto, a casca, em diversas áreas, sejam
elas nas indústrias agrícola, alimentar, cosmética, automóvel, ambiental e farmacêutica
com aplicações em medicina.
O valor nutricional da polpa e da casca da banana e o teor em compostos fenólicos
variam consoante a variedade da banana, o seu estado de maturação e a estação do ano.
Neste sentido, serão pesquisadas as propriedades nutricionais e o teor em compostos
fenólicos tanto da polpa como da casca da banana de diferentes espécies.
Ao longo desta dissertação foi possível verificar que a casca da banana é
nutricionalmente tão rica como a polpa da banana, apesar de existirem diferenças notórias
nos vários componentes, por exemplo a casca da banana é mais rica em fibra, carboidratos
proteína e, consequentemente, aminoácidos, do que a polpa da banana, mas mais pobre
no teor de água e açúcares totais.
Relativamente à bioatividade, o teor de compostos fenólicos totais é significativamente
maior na casca da banana, pelo que também é possível concluir que a casca da banana
tem mais poder antioxidante do que a polpa da banana.
Após a pesquisa bibliográfica efetuada, verificou-se que a casca da banana se mostrou
eficaz quando utilizada em várias indústrias, nomeadamente química, agrícola, ambiental,
alimentar, cosmética, farmacêutica, automóvel e energética.
Assim, pode dizer-se que a casca de banana é um recurso de valor acrescentado,
versátil, de baixo custo e de elevada disponibilidade que poderá servir como alternativa a
muitos materiais que, possivelmente, serão mais caros, raros e prejudiciais para a saúde
humana e o meio ambiente.
With the escalating concerns about food waste and environmental impact, there is an urgent need to explore sustainable alternatives that can address waste and benefit the environment. This project aims to study a readily available and low-cost vegetable matrix, namely the banana. The focus will be on valuing and reusing its pulp and, more importantly, its by-product, the peel. The potential applications span several industries, including agriculture, food, cosmetics, automotive, environmental, and pharmaceutical, with potential medical applications. The nutritional value of both the banana pulp and peel and their phenolic compound content fluctuates based on the banana variety, its ripeness, and the season. Accordingly, this research will delve into the nutritional properties and phenolic compound content in both the pulp and peel of various banana species. This study showed that the banana peel is as nutritionally rich as the banana pulp. However, there are distinctive differences: for instance, the banana peel has a higher fiber content, carbohydrates, proteins, and, subsequently, amino acids compared to the banana pulp. Conversely, it contains less water and total sugar. Regarding bioactivity, the banana peel displays a significantly higher content of total phenolic compounds. This indicates that the banana peel possesses greater antioxidant capacity than the banana pulp. Reviewing existing literature, the banana peel has shown promise in various chemical, agricultural, environmental, food, cosmetics, pharmaceutical, automotive and energy sectors. In conclusion, the banana peel stands out as a value-added, versatile, low-cost, and widely available resource. It has the potential to replace certain materials that might be more expensive, scarce, and detrimental to both human health and the environment.
