Abstract(s)
O cânhamo é uma espécie da planta Cannabis sativa L. com teor de trans-Δ-9- tetrahidrocanabinol (THC), inferior a 0,3%, sendo este o principal composto psicotrópico da planta. O cultivo da planta apresenta vantagens em comparação a outras culturas, sendo capaz de resistir a diversas condições agroecológicas. O cânhamo tem sido utilizado principalmente pelas indústrias de fibras e pela indústria alimentar. A China é a maior produtora de cânhamo para fins industriais. O cultivo e consumo de produtos de cânhamo nomeadamente para fins alimentares é legal e regulamentado em cerca de 50 países, entre os quais Portugal. Já, pelo contrário, no Brasil o cultivo e consumo de cânhamo não é permitido. Na indústria de alimentos, as sementes destacam-se e têm sido alvo de numerosos estudos científicos pelas suas propriedades nutricionais. As sementes contêm mais de 30% de óleo e cerca de 25% de proteínas, sendo ainda ricas em fibras dietéticas, vitaminas e minerais. O presente estudo teve como objetivos i) fazer uma revisão da literatura técnica e científica sobre o cânhamo e suas aplicações e ii) explorar o conhecimento e interesse dos consumidores brasileiros e portugueses no consumo alimentos com cânhamo na sua composição. Para a prossecução deste segundo objetivo foi realizado um inquérito online que contou com a participação de 255 indivíduos, 58% brasileiros e 41% portugueses. No geral, os participantes demonstraram ter pouco ou nenhum conhecimento sobre o cânhamo, até mesmo quem já havia consumido alimentos com cânhamo. Os brasileiros representam a maioria que não conhecem e nunca consumiram o cânhamo, dadas as restrições legais em vigor no Brasil, mas estão mais predispostos a consumir estes alimentos que os portugueses. Mais de metade dos participantes no estudo que já consumiram alimentos com cânhamo apontaram a curiosidade como a principal razão de consumo (54%) seguida do valor nutricional (21%). Os resultados mostraram ainda que há mercado para explorar e inovar, mas que a população das duas nacionalidades ainda tem pouco conhecimento sobre o assunto.
Hemp is a species of the Cannabis sativa L. plant with less than 0.3% trans-Δ-9- tetrahydrocannabinol (THC) content, which is the main psychotropic compound of the plant. The cultivation of the plant has advantages compared to other crops, being able to withstand various agroecological conditions. Hemp has been used mainly by the fiber industries and the food industry. China is the largest producer of hemp for industrial purposes. The cultivation and consumption of hemp products, namely for food purposes, is legal and regulated in around 50 countries, including Portugal. On the other hand, in Brazil the cultivation and consumption of hemp is not allowed. In the food industry, seeds stand out and have been the subject of numerous scientific studies for their nutritional properties. The seeds contain more than 30% oil and about 25% protein, and are also rich in dietary fiber, vitamins, and minerals. The present study aimed to i) review the technical and scientific literature on hemp and its applications and ii) explore the knowledge and interest of Brazilian and Portuguese consumers in consuming foods with hemp in their composition. For the pursuit of this second objective, an online survey was carried out with the participation of 255 individuals, 58% Brazilian and 41% Portuguese. Overall, participants were shown to have little or no knowledge of hemp, even those who had previously consumed hemp foods. Brazilians represent the majority who do not know and have never consumed hemp, given the legal restrictions in force in Brazil, but they are more predisposed to consume these foods than the Portuguese. More than half of the study participants who had already consumed hemp foods cited curiosity as the main reason for consumption (54%) followed by nutritional value (21%). The results also showed that there is a market to explore and innovate, but that the population of both nationalities still has little knowledge on the subject.
