Maize, the second most important genetically modified (GM) crop, has the highest number of authorised GM events for food and feed in the EU. To provide consumer’s information, labelling for food products containing more than 0.9% of GM material is demanded by the actual EU legislation. Analysis of foods is then essential to detect and quantify GM maize material and verify the compliance with labelling informati...
Species identification in meat products has grown in interest in recent years since these foodstuffs are susceptible targets for fraudulent labelling. In this work, a real-time PCR approach based on SYBR Green dye was proposed for the quantitative detection of pork meat in processed meat products. For the development of the method, binary meat mixtures containing known amounts of pork meat in poultry meat were ...
Soybean is a food ingredient with both techno- and biofunctionality properties, whose use has been increasing considerably in the past decades [I]. Besides its numerous applications, soybean is widely used by the food industry in processed foodstuffs such as sausages, hamburgers or hams. However, since soybean is considered one of the most common foods known to cause allergic reactions in sensitized individuais...
Este trabalho foi realizado no âmbito da unidade curricular de Projeto da Licenciatura em Engenharia Biomédica do Instituto Politécnico de Bragança. Teve como principal objetivo desenvolver um processo de microencapsulação para proteção do α-tocoferol, a principal forma da vitamina E. O α-tocoferol é um antioxidante que possui um papel importante na proteção do organismo contra certos tipos de cancro e do envel...
Authenticity assessment and fraud detection in processed meat products have becn attracting an increased attention driven by public health, economic and legal cancems, and also for religiolls reasons. Currcntly, ooe af the major issues conceming adulterations in the meat indust:ry regards the fraudulent substitution af higher commercial valued meat species by less expensive oDes [1]. The manufacture af traditio...
Honey is a natural product highly consumed due its known associalion wilh heallh benefits. Monofloral and Protecled Designation 01 Origin (PDO) honeys have generally higher economic value since Ihey are considered to have higher quality due lo its specific and well-delined flavor and aroma, Thus, these products are susceptible to misleading labeling and Iraudulenl praclices, making their assessment 01 bolanical...
Honey can be c1assified based on the type of flowers used by the bees to collect pollen as unifloral honey, if arising predominantly from a single botanical origin, which generally represents more than 45% of the total pollen content, or as multi floral honey, if it is produced from various plant species A single plant origin should assure a product of better quality because it guarantees a specific and well-de...
Os nanotransportadores (NT) são sistemas desenvolvidos à escala nanométrica (< 1μm) sendo usados como veículo de substâncias ativas (SA) [1]. Atualmente a maioria dos trabalhos foca o encapsulamento de fármacos e caracterização dos NT obtidos, sendo escassos os dados relativos a NT sem SA. Este trabalho teve como objectivo a preparação e caracterização de diferentes tipos de NT sem SA: lipossomas (L), nanocápsu...
A par da evolução da nanotecnologia, assiste-se a uma crescente preocupação sobre eventuais riscos/toxicidade que os nanotransportadores possam representar [1]. A maioria dos trabalhos publicados relativos à avaliação da citotoxicidade in vitro de nanotransportadores (NT) incide na comparação quando a substância ativa (SA) é administrada em solução ou nanoencapsulada, sendo escassos os estudos que visam avaliar...
A indústria do calçado é o núcleo de um importante cluster da economia nacional. A sua evolução refletiu-se no aumento da produtividade e no valor bruto da produção. Como resultado, o preço do calçado exportado em 2011 subiu para os 23,70 euros/par, tendo o valor global das exportações atingido 1548 milhões de euros (APICCAPS, 2012). Atualmente, este setor procura afirmar-se em nichos de mercado com maior exigê...
